| 1 | Impact of lattice relaxations on phase transitions in a high-entropy alloy studied by machine-learning potentials显示文摘Recently,high-entropy alloys(HEAs)have attracted wide attention due to their extraordinary materials properties.A main challenge in identifying new HEAs is the lack of efficient approaches for exploring their huge compositional space.Ab initio calculations have emerged as a powerful approach that complements experiment.However,for multicomponent alloys existing approaches suffer from the chemical complexity involved.In this work we propose a method for studying HEAs computationally.Our approach is based on the application of machine-learning potentials based on ab initio data in combination with Monte Carlo simulations.The high efficiency and performance of the approach are demonstrated on the prototype bcc NbMoTaW HEA.The approach is employed to study phase stability,phase transitions,and chemical short-range order.The importance of including local relaxation effects is revealed:they significantly stabilize single-phase formation of bcc NbMoTaW down to room temperature.Finally,a so-far unknown mechanism that drives chemical order due to atomic relaxation at ambient temperatures is discovered. | Tatiana Kostiuchenko Fritz Körmann Jörg Neugebauer Alexander Shapeev | 2019 | npj Computational Materials2019，，1： | 17 |
| 2 | Laparoscopic surgery for benign and malign diseases of the digestive system:Indications,limitations,and evidence显示文摘The laparoscopic technique was introduced in gastrointestinal surgery in the mid 1980s.Since then,the development of this technique has been extraordinary.Triggered by technical innovations(stapling devices or coagulation/dissecting devices),nowadays any type of gastrointestinal resection has been successfully performed laparoscopically and can be performed laparoscopically dependent on the patient’s condition.This summary gives an overview over 30 years of laparoscopic surgery with focus on today’s indications and evidence.Main indications remain the more common procedures,e.g.,appendectomy,cholecystectomy,bariatric procedures or colorectal resections.For all these indications,the laparoscopic approach has become the gold standard with less perioperative morbidity.Regarding oncological outcome there have been several highquality randomized controlled trials which demonstrated equivalency between laparoscopic and open colorectal resections.Less common procedures like esophagectomy,oncological gastrectomy,liver and pancreatic resections can be performed successfully as well by anexperienced surgeon.However,the evidence for these special indications is poor and a general recommendation cannot be given.In conclusion,laparoscopic surgery has revolutionized the field of gastrointestinal surgery by reducing perioperative morbidity without disregarding surgical principles especially in oncological surgery. | Markus Alexander Küper Friederike Eisner Alfred K?nigsrainer J?rg Glatzle | 2014 | World Journal of Gastroenterology2014，20，17： | 9 |

| 4 | Clinical and economic consequences of pancreatic fistula after elective pancreatic resection显示文摘BACKGROUND:Postoperative pancreatic fistula is the main cause of morbidity after pancreatic resection.This study aimed to quantify the clinical and economic consequences of pancreatic fistula in a medium-volume pancreatic surgery center.METHODS:Hospital records from patients who had undergone elective pancreatic resection in our department were identified.Pancreatic fistula was defined according to the International Study Group on Pancreatic Fistula(ISGPF).The consequences of pancreatic fistula were determined by treatment cost,hospital stay,and out-patient follow-up until the pancreatic fistula was completely healed.All costs of the treatment are calculated in Euros.The cost increase index was calculated for pancreatic fistula of grades A,B,and C as multiples of the total cost for the no fistula group.RESULTS:In 54 months,102 patients underwent elective pancreatic resections.Forty patients(39.2%) developed pancreatic fistula,and 54 patients(52.9%) had one or more complications.The median length of hospital stay for the no fistula,grades A,B,and C fistula groups was 12.5,14,20,and 59 days,respectively.The hospital stay of patients with fistula of grades B and C was significantly longer than that of patients with no fistula(P<0.001).The median total cost of the treatment was 4952,4679,8239,and 30 820 Euros in the no fistula,grades A,B,and C fistula groups,respectively.CONCLUSIONS:The grading recommended by the ISGPF is useful for comparing the clinical severity of fistula and for analyzing the clinical and economic consequences of pancreatic fistula.Pancreatic fistula prolongs the hospital stay and increases the cost of treatment in proportion to the severity of the fistula. | Filip Ceka Bohumil Jon Zdeněk ubrt Alexander Ferko | 2013 | Hepatobiliary & Pancreatic Diseases International2013，12，5： | 7 |
| 5 | Primary squamous cell carcinoma of the rectum: An update and implications for treatment显示文摘AIM: To provide an update on the aetiology, pathogenesis, diagnosis, staging and management of rectal squamous cell carcinoma(SCC).METHODS: A systematic review was conducted according to the preferred reporting items for Systematic Reviews and Meta-Analyses guidelines. A comprehensive search of Ovid MEDLINE was performed with the reference list of selected articles reviewed to ensure all relevant publications were captured. The search strategy was limited to the English language, spanning from 1946 to 2015. A qualitative analysis was undertaken examining patient demographics, clinical presentation, diagnosis, staging, treatment and outcome. The quantitaive analysis was limited to data extracted on treatment and outcomes including radiological, clinical and pathological complete response where available. The narrative and quantitative review were synthesised in concert.RESULTS: The search identified 487 articles in total with 79 included in the qualitative review. The quantitative analysis involved 63 articles, consisting of 43 case reports and 20 case series with a total of 142 individual cases. The underlying pathogenesis of rectal SCC while unclear, continues to be defined, with increasing evidence of a metaplasia-dysplasia-carcinoma sequence and a possible role for human papilloma virus in this progression. The presentation is similar to rectal adenocarcinoma, with a diagnosis confirmed by endoscopic biopsy. Many presumed rectal SCC's are in fact an extension of an anal SCC, and cytokeratin markers are a useful adjunct in this distinction. Staging is most accurately reflected by the tumour-nodemetastasis classification for rectal adenocarcinoma. It involves examining locoregional disease by way of magnetic resonance imaging and/or endorectal ultrasound, with systemic spread excluded by way of computed tomography. Positron emission tomography is integral in the workup to exclude an external siteof primary SCC with metastasis to the rectum. While the optimal treatment remains as yet undefined, recent studies have demonstrated a global shift away from surgery towards definitive chemoradiotherapy as primary treatment. Pooled overall survival was calculated to be 86% in patients managed with chemoradiation compared with 48% for those treated traditionally with surgery. Furthermore, local recurrence and metastatic rates were 25% vs 10% and 30% vs 13% for the chemoradiation vs conventional treatment cohorts.CONCLUSION: The changing paradigm in the treatment of rectal SCC holds great promise for improved outcomes in this rare disease. | Glen R Guerra Cherng H Kong Satish K Warrier Andrew C Lynch Alexander G Heriot Samuel Y Ngan | 2016 | World Journal of Gastrointestinal Surgery2016，8，3： | 5 |
| 6 | Clinical outcomes following salvage Gamma Knife radiosurgery for recurrent glioblastoma显示文摘Glioblastoma multiforme(GBM) is the most common malignant primary brain tumor with a survival prognosis of 14-16 mo for the highest functioning patients. Despite aggressive, multimodal upfront therapies, the majority of GBMs will recur in approximately six months. Salvage therapy options for recurrent GBM(r GBM) are an area of intense research. This study compares recent survival and quality of life outcomes following Gamma Knife radiosurgery(GKRS) salvage therapy. Following a Pub Med search for studies usingGKRS as salvage therapy for malignant gliomas, nine articles from 2005 to July 2013 were identified which evaluated rG BM treatment. In this review, we compare overall survival following diagnosis, overall survival following salvage treatment, progression-free survival, time to recurrence, local tumor control, and adverse radiation effects. This report discusses results for rG BM patient populations alone, not for mixed populations with other tumor histology grades. All nine studies reported median overall survival rates(from diagnosis, range:16.7-33.2 mo; from salvage, range:9-17.9 mo). Three studies identified median progression-free survival(range:4.6-14.9 mo). Two showed median time to recurrence of GBM. Two discussed local tumor control. Six studies reported adverse radiation effects(range:0%-46% of patients). The greatest survival advantages were seen in patients who received GKRS salvage along with other treatments, like resection or bevacizumab, suggesting that appropriately tailored multimodal therapy should be considered with each rG BM patient. However, there needs to be a randomized clinical trial to test GKRS for rG BM before the possibility of selection bias can be dismissed. | Erik W Larson Halloran E Peterson Wayne T Lamoreaux Alexander R MacKay Robert K Fairbanks Jason A Call Jonathan D Carlson Benjamin C Ling John J Demakas Barton S Cooke Christopher M Lee | 2014 | World Journal of Clinical Oncology2014，5，2： | 5 |

| 8 | Nonalcoholic fatty liver disease is associated with benign gastrointestinal disorders显示文摘AIM:To explore associations between nonalcoholic fatty liver disease(NAFLD)and benign gastrointestinal and pancreato-biliary disorders.METHODS:Patient demographics,diagnoses,and hospital outcomes from the 2010 Nationwide Inpatient Sample were analyzed.Chronic liver diseases were identified using International Classification of Diseases,the 9thRevision,Clinical Modification codes.Patients with NAFLD were compared to those with other chronic liver diseases for the endpoints of total hospital charges,disease severity,and hospital mortality.Multivariable stepwise logistic regression analyses to assess for the independent association of demographic,comorbidity,and diagnosis variables with the event of NAFLD(vs other chronic liver diseases)were also performed.RESULTS:Of 7800441 discharge records,32347(0.4%)and 271049(3.5%)included diagnoses of NAFLD and other chronic liver diseases,respectively.NAFLD patients were younger(average 52.3 years vs55.3 years),more often female(58.8%vs 41.6%),less often black(9.6%vs 18.6%),and were from higher income areas(23.7%vs 17.7%)compared to counterparts with other chronic liver diseases(all P<0.0001).Diabetes mellitus(43.4%vs 28.9%),hypertension(56.9%vs 47.6%),morbid obesity(36.9%vs 8.0%),dyslipidemia(37.9%vs 15.6%),and the metabolic syndrome(28.75%vs 8.8%)were all more common among NAFLD patients(all P<0.0001).The average total hospital charge($39607 vs$51665),disease severity scores,and intra-hospital mortality(0.9%vs6.0%)were lower among NALFD patients compared to those with other chronic liver diseases(all P<0.0001).Compared with other chronic liver diseases,NAFLD was significantly associated with diverticular disorders[OR=4.26(3.89-4.67)],inflammatory bowel diseases[OR=3.64(3.10-4.28)],gallstone related diseases[OR=3.59(3.40-3.79)],and benign pancreatitis[OR=2.95(2.79-3.12)]on multivariable logistic regression(all P<0.0001)when the latter disorders were the principal diagnoses on hospital discharge.Similar relationships were observed when the latter disorders were associated diagnoses on hospital discharge.CONCLUSION:NAFLD is associated with diverticular,inflammatory bowel,gallstone,and benign pancreatitis disorders.Compared with other liver diseases,patients with NAFLD have lower hospital charges and mortality. | Srinevas K Reddy Min Zhan H Richard Alexander Samer S El-Kamary | 2013 | World Journal of Gastroenterology2013，19，45： | 4 |
| 9 | Pancreatic Castleman disease treated with laparoscopic distal pancreatectomy显示文摘BACKGROUND: Castleman disease is an uncommon lympho-proliferative disorder most frequently occurring in the mediastinum. Abdominal forms are less frequent, with pancreatic localization of the disease in particular being extremely rare. Only seventeen cases have been described in the world literature. METHOD: This report describes an interesting and unusual case of pancreatic Castleman disease treated with laparoscopic resection. RESULTS: A 48-year-old woman presented with epigastric pain. CT scan showed a well-encapsulated mass on the ventral border of the pancreas. Endosonography with fine needle aspiration biopsy was performed. Biopsy showed lymphoid elements and structures of a normal lymph node. The patient was treated with laparoscopic distal pancreatectomy. The pancreas was transected with a Ligasure device and the pancreatic stump was secured with a manual suture. One year after surgery the patient was complaint-free and showed no signs of recurrence of the disease. CONCLUSIONS: Laparoscopic distal pancreatectomy is a feasible and safe method for the treatment of lesions in the body and tail of the pancreas. Transection of the pancreas with a Ligasure device offers the advantages of low bleeding and low risk of pancreatic fistula. | Filip ecka Alexander Ferko Bohumil Jon Zdeněk ubrt Petra Kaparová Rudolf Repák | 2013 | Hepatobiliary & Pancreatic Diseases International2013，12，3： | 4 |
| 10 | Efficient training of ANN potentials by including atomic forces via Taylor expansion and application to water and a transition-metal oxide显示文摘Artificial neural network(ANN)potentials enable the efficient large-scale atomistic modeling of complex materials with near firstprinciples accuracy.For molecular dynamics simulations,accurate energies and interatomic forces are a prerequisite,but training ANN potentials simultaneously on energies and forces from electronic structure calculations is computationally demanding.Here,we introduce an efficient alternative method for the training of ANN potentials on energy and force information,based on an extrapolation of the total energy via a Taylor expansion.By translating the force information to approximate energies,the quadratic scaling with the number of atoms exhibited by conventional force-training methods can be avoided,which enables the training on reference datasets containing complex atomic structures. | April M.Cooper Johannes Kästner Alexander Urban Nongnuch Artrith | 2020 | npj Computational Materials2020，，1： | 3 |
| 11 | PI 3-kinase pathway is responsible for antiapoptotic effects of atrial natriuretic peptide in rat liver transplantation显示文摘AIM:To investigate the in vivo effect of atrial natriureticpeptide(ANP)and its signaling pathway during ortho-topic rat liver transplantation.METHODS:Rats were infused with NaCl,ANP(5 μg/kg),wortmannin(WM,16 μg/kg),or a combination ofboth for 20 min.Livers were stored in UW solution(4°C)for 24 h,transplanted and reperfused.Apoptosis wasexamined by caspase-3 activity and TUNEL staining.Phosphorylation of Akt and Bad was visualized by West-ern blotting and phospho-Akt-localization by confocalmicroscopy.RESULTS:ANP-pretreatment decreased caspase-3activity and TUNEL-positive cells after cold ischemia,indicating antiapoptotic effects of ANP in vivo.The an-tiapoptotic signaling of ANP was most likely caused byphosphorylation of Akt and Bad,since pretreatment withPI 3-kinase inhibitor WM abrogated the ANP-inducedreduction of caspase-3 activity.Interestingly,analysis ofliver tissue by confocal microscopy showed translocationof phosphorylated Akt to the plasma membrane of hepa-tocytes evoked by ANP.CONCLUSION:ANP activates the PI-3-kinase pathwayin the liver in vivo leading to phosphorylation of Bad, an event triggering antiapoptotic signaling cascade inischemic liver. | Uwe Grutzner Melanie Keller Michael Bach Alexandra K Kiemer Herbert Meissner Manfred Bilzer Stefan Zahler Alexander L Gerbes Angelika M Vollmar | 2006 | World Journal of Gastroenterology2006，12，7： | 3 |
| 12 | Long-term survival of a patient after resection of a gastrointestinal stromal tumor arising from the pancreas显示文摘BACKGROUND:Gastrointestinal stromal tumors (GISTs) may arise in any part of the gastrointestinal tract;extragastrointestinal locations are extremely rare.Only a few cases of extragastrointestinal stromal tumor arising from the pancreas were reported.None of the reports described a long-term follow-up of the patients.METHOD:This report describes an interesting and unusual case of GIST arising from the pancreas.RESULTS:A 74-year-old female presented with a palpable abdominal mass.CT scan showed a large mass 11×8×4 cm originating from the tail of the pancreas.Percutaneous biopsy revealed a GIST predominantly with spindle cells,but some parts also contained epitheloid cells.The patient was treated by distal pancreatic resection with splenectomy.Immunohistochemistry of the tumor showed a staining pattern characteristic of GIST.The patient has achieved a long-term survival of five years and six months without any sign of recurrence of the disease.CONCLUSION:This is the first reported case of an extragastrointestinal stromal tumor arising from the pancreas treated surgically,with a long-term survival. | Filip eka Bohumil Jon Alexander Ferko Zdeněk ubrt Dimitar H Nikolov Věra Tyová | 2011 | Hepatobiliary & Pancreatic Diseases International2011，10，3： | 3 |
| 13 | Effect of process parameters on additive-free electrospinning of regenerated silk fibroin nonwovens显示文摘Silk fibroin is a biomaterial with multiple beneficial properties for use in regenerative medicine and tissue engineering.When dissolving and processing the reconstituted silk fibroin solution by electrospinning,the arrangement and size of fibers can be manifold varied and according fiber diameters reduced to the nanometer range.Such nonwovens show high porosity as well as potential biocompatibility.Usually,electrospinning of most biomaterials demands for the application of additives,which enable stable electrospinning by adjusting viscosity,and are intended to evaporate during processing or to be washed out afterwards.However,the use of such additives increases costs and has to be taken into account in terms of biological risks when used for biomedical applications.In this study,we explored the possibilities of additive-free electrospinning of pure fibroin nonwovens and tried to optimize process parameters to enable stable processing.We used natural silk derived from the mulberry silkworm Bombyx mori.After degumming,the silk fibroin was dissolved and the viscosity of the spinning solution was controlled by partial evaporation of the initial solving agent.This way,we were able to completely avoid the use of additives and manufacture nonwovens,which potentially offer higher biocompatibility and reduced immunogenicity.Temperature and relative humidity during electrospinning were systematically varied(25–35°C,25–30%RH).In a second step,the nonwovens optionally underwent methanol treatment to initiate beta-sheet formation in order to increase structural integrity and strength.Comprehensive surface analysis on the different nonwovens was performed using scanning electron microscopy and supplemented by additional mechanical testing.Cytotoxicity was evaluated using BrdU-assay,XTT-assay,LDH-assay and live-dead staining.Our findings were,that an increase of temperature and relative humidity led to unequal fiber diameters and defective nonwovens.Resistance to penetration decreased accordingly.The most uniform fiber diameters of 998±63 nm were obtained at 30°C and 25%relative humidity,also showing the highest value for resistance to penetration(0.20 N).The according pure fibroin nonwoven also showed no signs of cytotoxicity.However,while the biological response showed statistical evidence,the material characteristics showed no statistically significant correlation to changes of the ambient conditions within the investigated ranges.We suggest that further experiments should explore additional ranges for temperature and humidity and further focus on the repeatability of material properties in dependency of suitable process windows. | Alexander Kopp Ralf Smeets Martin Gosau Nadja Kröger Sandra Fuest Marius Köpf Magnus Kruse Judith Krieger Rico Rutkowski Anders Henningsen Simon Burg | 2020 | Bioactive Materials2020，5，2： | 3 |
| 14 | Intra-abdominal drainage following pancreatic resection:A systematic review显示文摘AIM: To study all the aspects of drain management in pancreatic surgery.METHODS: We conducted a systematic review according to the PRISMA guidelines. We searched the Cochrane Central Registry of Controlled Trials,EMBASE,Web of Science,and Pub Med(MEDLINE) for relevant articles on drain management in pancreatic surgery. The reference lists of relevant studies were screened to retrieve any further studies. We included all articles that reported clinical studies on human subjects with elective pancreatic resection and that compared various strategies of intra-abdominal drain management,such as drain vs no drain,selective drain use,early vs late drain extraction,and the use of different types of drains. RESULTS: A total of 19 studies concerned with drain management in pancreatic surgery involving 4194 patients were selected for this systematic review. We included studies analyzing the outcomes of pancreatic resection with and without intra-abdominal drains,studies comparing early vs late drain removal and studies analyzing different types of drains. The majority of the studies reporting equal or superior results for pancreatic resection without drains were retrospective and observational with significant selection bias. One recent randomized trial reported higher postoperative morbidity and mortality with routine omission of intraabdominal drains. With respect to the timing of drain removal,all of the included studies reported superior results with early drain removal. Regarding the varioustypes of drains,there is insufficient evidence to determine which type of drain is more suitable following pancreatic resection. CONCLUSION: The prophylactic use of drains remains controversial. When drains are used,early removal is recommended. Further trials comparing types of drains are ongoing. | Filip Cecka Martin Lovecek Bohumil Jon Pavel Skalicky Zdeněk Subrt Cestmír Neoral Alexander Ferko | 2015 | World Journal of Gastroenterology2015，21，40： | 2 |
| 15 | Should antibiotics be administered before arthroscopic knee surgery? A systematic review of the literature显示文摘AIM To explore the current evidence surrounding the administration of prophylactic antibiotics for arthroscopic knee surgery. METHODS Databases were searched from inception through May of 2018 for studies examining prophylactic antibiotic use and efficacy in knee arthroscopy. Studies with patient data were further assessed for types of arthroscopic procedures performed,number of patients in the study,use of antibiotics,and outcomes with the intention of performing a pooled analysis. Data pertaining to 'deep tissue infection' or 'septic arthritis' were included in our analysis. Reported data on superficial infection were not included in our data analysis. For the pooled analysis,a relative risk ratio was calculated and χ~2 tests were used to assess for statistical significance between rates of infection amongst the various patient groups. Post hoc power analyses were performed to compute the statistical power obtained from our sample sizes. Number needed to treat analyses were performed for statistically significant differences by dividing 1 by the difference between the infection rates of the antibiotic and no antibiotic groups. An alpha value of 0.05 was used for our analysis. Study heterogeneity was assessed by Cochrane's Q test as well as calculation of the I^2 value.RESULTS A total of 49682 patients who underwent knee ar-throscopy for a diverse set of procedures across 19 studies met inclusion critera for pooled analysis. For those not undergoing graft procedures,there were 27 cases of post-operative septic arthritis in 34487 patients(0.08%) who received prophylactic antibiotics and 16 cases in 10911(0.15%) who received none [risk ratio(RR) = 0.53,95% confidence interval(CI): 0.29-0.99,P = 0.05]. A sub-group analysis in which bony procedures were excluded was performed which found no significant difference in infection rates between patients that received prophylactic antibiotics and patients that did not(P > 0.05). All anterior cruciate ligament reconstruction studies used prophylactic antibiotics,but two studies investigating the effect of soaking the graft in vancomycin in addition to standard intravenous(IV) prophylaxis were combined for analysis. There were 19 cases in 1095 patients(1.74%) who received IV antibioitics alone and no infections in 2034 patients who received IV antibiotics and had a vancomycin soaked graft(RR = 0.01,95%CI: 0.001-0.229,P < 0.01).CONCLUSION Prophylactic antibiotics are effective in preventing septic arthritis following simple knee arthroscopy. In procedures involving graft implantation,graft soaking reduces the rate of infection. | John Carney Nathanael Heckmann Erik N Mayer Ram K Alluri Carleton Thomas Vangsness George F Hatch Ⅲ Alexander E Weber | 2018 | World Journal of Orthopedics2018，9，11： | 2 |
| 16 | Is the schatzki ring a unique esophageal entity?显示文摘AIM:To study,whether the association of Schatzki rings with other esophageal disorders support one of the theories about its etiology.METHODS:From 1987 until 2007,all patients with newly diagnosed symptomatic Schatzki rings (SRs) were prospectively registered and followed.All of them underwent structured interviews with regards to clinical symptoms,as well as endoscopic and/or radiographic examinations.Endoscopic and radiographic studies determined the presence of an SR and additional morphological abnormalities.RESULTS:One hundred and sixty-seven patients (125 male,42 female) with a mean age of 57.1±14.6 years were studied.All patients complained of intermittent dysphagia for solid food and 113 (79.6%) patients had a history of food impaction.Patients experienced symptoms for a mean of 4.7±5.2 years before diagnosis.Only in 23.4% of the 64 patients who had endoscopic and/or radiological examinations before their first presentation to our clinic,was the SR previously diagnosed.At presentation,the mean ring diameter was 13.9±4.97 mm.One hundred and sixty-two (97%) patients showed a sliding hiatal hernia.Erosive reflux esophagitis was found in 47 (28.1%) patients.Twenty-six (15.6%) of 167 patients showed single or multiple esophageal webs;five (3.0%) patients exhibited eosinophilic esophagitis;and four (2.4%) had esophageal diverticula.Four (7%) of 57 patients undergoing esophageal manometry had nonspecific esophageal motility disorders.CONCLUSION:Schatzki rings are frequently associated with additional esophageal disorders,which support the assumption of a multifactorial etiology.Despite typical symptoms,SRs might be overlooked. | Michaela Müller Ines Gockel Philip Hedwig Alexander J Eckardt Kathrin Kuhr Jochem Knig Volker F Eckardt | 2011 | World Journal of Gastroenterology2011，17，23： | 2 |
| 17 | Procedural complexity independent of P2Y12 reaction unit(PRU)values is associated with acute in situ thrombosis in Pipeline flow diversion of cerebral aneurysms显示文摘background Acute in situ thrombosis is an ischaemic phenomenon during Pipeline embolisation device(PED)procedures with potentially high morbidity and mortality.There is controversy regarding the role of platelet function testing with P2Y12 assay as a predictor of intraprocedural thromboembolic events.There is limited knowledge on whether procedural complexity influences these events.Methods Data were collected retrospectively on 742 consecutive PED cases at a single institution.Patients with intraprocedural acute thrombosis were compared with patients without these events.results A cohort of 37 PED cases with acute in situ thrombosis(mean age 53.8 years,mean aneurysm size 8.4 mm)was matched with a cohort of 705 PED cases without intraprocedural thromboembolic events(mean age 56.4 years,mean aneurysm size 6.9 mm).All patients with in situ thrombosis received intra-arterial and/or intravenous abciximab.The two groups were evenly matched in patient demographics,previous treatment/subarachnoid hemorrhage(SAH)and aneurysm location.There was no statistical difference in postprocedural P2Y12 reaction unit(PRU)values between the two groups,with a mean of 156 in the in situ thrombosis group vs 148 in the control group(p=0.5894).Presence of cervical carotid tortuosity,high cavernous internal carotid artery grade,need for multiple PED and vasospasm were not significantly different between the two groups.The in situ thrombosis group had statistically significant longer fluoroscopy time(60.4 vs 38.4 min,p<0.0001),higher radiation exposure(3476 vs 2160 mGy,p<0.0001),higher rates of adjunctive coiling(24.3% vs 8.37%,p=0.0010)and higher utilisation of balloon angioplasty(37.8% vs 12.2%,p<0.0001).Clinically,the in situ thrombosis cohort had higher incidence of major and minor stroke,intracerebral haemorrhage and length of stay.Conclusions Predictors of procedural complexity(higher radiation exposure,longer fluoroscopy time,adjunctive coiling and need for balloon angioplasty)are associated with acute thrombotic events during PED placement,independent of PRU values. | Bowen Jiang Matthew T Bender Erick M Westbroek Jessica K Campos Li-Mei Lin Risheng Xu Rafael J Tamargo Judy Huang Geoffrey P Colby Alexander L Coon | 2018 | Stroke & Vascular Neurology2018，3，3： | 2 |
