| 1 | Three benefits of microcatheters for retrograde transvenous obliteration of gastric varices显示文摘AIM:To evaluate the usefulness of the microcatheter techniques in balloon-occluded retrograde transvenous obliteration (BRTO) of gastric varices.METHODS:Fifty-six patients with gastric varices underwent BRTOs using microcatheters.A balloon catheter was inserted into gastrorenal or gastrocaval shunts.A microcatheter was navigated close to the varices,and sclerosant was injected into the varices through the microcatheter during balloon occlusion.The next morning,thrombosis of the varices was evaluated by contrast enhanced computed tomography (CE-CT).In patients with incomplete thrombosis of the varices,a second BRTO was performed the following day.Patients were followed up with CE-CT and endoscopy.RESULTS:In all 56 patients,sclerosant was selectively injected through the microcatheter close to the varices.In 9 patients,microcoil embolization of collateral veinswas performed using a microcatheter.In 12 patients with incomplete thrombosis of the varices,additional injection of sclerosant was performed through the microcatheter that remained inserted overnight.Complete thrombosis of the varices was achieved in 51 of 56 patients,and the remaining 5 patients showed incomplete thrombosis of the varices.No recurrence of the varices was found in the successful 51 patients after a median follow up time of 10.5 mo.We experienced one case of liver necrosis,and the other complications were transient.CONCLUSION:The microcatheter techniques are very effective methods for achieving a higher success rate of BRTO procedures. | Tetsuo Sonomura Wataru Ono Morio Sato Shinya Sahara Kouhei Nakata Hiroki Sanda Nobuyuki Kawai Hiroki Minamiguchi Motoki Nakai Kazushi Kishi | 2012 | World Journal of Gastroenterology2012，18，12： | 5 |
| 2 | Emergency balloon-occluded retrograde transvenous obliteration of ruptured gastric varices显示文摘AIM: To evaluate the effectiveness and safety of emergency balloon-occluded retrograde transvenous obliteration(BRTO) for ruptured gastric varices.METHODS: Emergency BRTO was performed in 17 patients with gastric varices and gastrorenal or gastrocaval shunts within 24 h of hematemesis and/or tarry stool.The gastric varices were confirmed by endoscopy,and the gastrorenal or gastrocaval shunts were identified by contrast-enhanced computed tomography(CE-CT).A 6-Fr balloon catheter(Cobra type) was inserted into the gastrorenal shunt via the right internal jugular vein,or into the gastrocaval shunt via the right femoral vein,depending on the varices drainage route.The sclerosant,5% ethanolamine oleate iopamidol,was injected into the gastric varices through the catheter during balloon occlusion.In patients with incom plete thrombosis of the varices after the first BRTO,a second BRTO was performed the following day.Patients were followed up by endoscopy and CE-CT at 1 d,1 wk,and 1,3 and 6 mo after the procedure,and every 6 mo thereafter.RESULTS: Complete thrombosis of the gastric varices was not achieved with the first BRTO in 7/17 patients because of large gastric varices.These patients underwent a second BRTO on the next day,and additional sclerosant was injected through the catheter.Complete thrombosis which led to disappearance of the varices was achieved in 16/17 patients,while the remaining patient had incomplete thrombosis of the varices.None of the patients experienced rebleeding or recurrence of the gastric varices after a median follow-up of 1130 d(range 8-2739 d).No major complications occurred after the procedure.However,esophageal varices worsened in 5/17 patients after a mean follow-up of 8.6 mo.CONCLUSION: Emergency BRTO is an effective and safe treatment for ruptured gastric varices. | Tetsuo Sonomura Wataru Ono Morio Sato Shinya Sahara Kouhei Nakata Hiroki Sanda Nobuyuki Kawai Hiroki Minamiguchi Motoki Nakai Kazushi Kishi | 2013 | World Journal of Gastroenterology2013，19，31： | 2 |

| 14 | 为从乳癌的内部乳房的淋巴节点转移的新奇的根除的高剂量的率 brachytherapy显示文摘 AIM:To develop a method of delivering an eradicative high radiotherapeutic dose safely preserving the surrounding skin in the treatment of internal mammary lymph node metastasis (IMLNM) of breast cancer. METHODS:We report a 38-year-old female patient with a solo IMLNM showing no response to 60 Gy in 2.5 Gy fractions of external beam radiotherapy. To eradicate this tumor, a boost brachytherapy plan was created after percutaneous insertion of an applicator needle into the IMLNM lesion avoiding the pleura and vessels under ultrasound monitoring. According to the dose distribution, the required thickness of a spacer between the skin and the tumor was determined, and hyaluronic gel was injected up to this thickness under ultrasound monitoring. We evaluated skin doses, target doses and clinical outcome. RESULTS:All procedures were performed easily. Sixteen Gy (34.7 Gy equivalent in 2 Gy fractions calculated by the linear quadratic model at α/β = 10:EQ 2, α/β = 10 , cumulative total was 101.9 Gy EQ 10) to 100% of the target volume was irradiated with cumulative maximum skin dose of 70 Gy EQ 2, α/β = 3 which was 98.7 Gy EQ 2, α/β = 3 without spacer. No procedure related-or late complications and no local recurrence at the treated site were observed for three years until expiration. CONCLUSION:We consider that this procedure will provide an eradicative high-dose irradiation to IMLNM of breast cancer, preserving skin from overdose complications. | Kazushi Kishi Hirokazu Tanino Tetsuo Sonomura Shintaro Shirai Yasutaka Noda Morio Sato Yoshitaka Okamura | 2012 | World Journal of Radiology2012，4，11： | 0 |
| 15 | Usefulness of the Guglielmi detachable coil for embolization of a systemic venous collateral after Fontan operation:A case report显示文摘Embolization of collateral veins is often treated with rigid coils(Gianturco and interlocking detachable coils type).However,when dealing with tortuous and dilated collateral veins,there is a high risk for technical failure and coil migration due to inflexibility of the coils.To safely and successfully solve this problem,Guglielmi detachable coils(GDC) can be used for embolization.Their flexibility allows for easy navigation in tortuous veins,low risk of unintended coil release or coil migration,and safe deployment.A 12-year-old girl with a single ventricle had severe cyanosis and a low exercise tolerance 5 years after Fontan procedure.The symp-toms were caused by a tortuous and dilated collateral from the left phrenic vein into the left pulmonary vein,forming a right-to-left shunt.The collateral,which had a large diameter and high flow,and therefore a high risk of coil migration,was successfully embolized with 8 GDC.There were no complications such as coil migration or cerebral infarction.Transcatheter embolization increased her systemic oxygen saturation from 81%-84% to 94%-95%,and increased her ability to exercise.The embolization procedure using flexible GDC was low risk compared with other rigid coil embolization techniques when performing embolization of tortuous and dilated collateral veins. | Tetsuo Sonomura Akira Ikoma Nobuyuki Kawai Tomohiro Suenaga Takashi Takeuchi Hiroki Minamiguchi Shunji Uchita Motoki Nakai Hiroyuki Suzuki Kazushi Kishi Morio Sato | 2012 | World Journal of Radiology2012，4，9： | 0 |
