| 1 | Stent placement is effective on both postoperative hepatic arterial pseudoaneurysm and subsequent portal vein stricture:A case report显示文摘To treat postoperative bleeding after hepato-pancreato-biliary surgery, interventional radiology has become essential. We report a case of coincidental pseudoan-eurysm and jejunal varices that were both successfully treated by stent-grafts. After a pancreaticoduodenec-tomy, the patient developed a pseudoaneurysm in the hepatic artery and a stenosis in its periphery. After establishing hepatic arterial flow by placing stent-grafts over both the pseudoaneurysm and the stenosis, the pseudoaneurysm was embolized with microcoils. Nine months later, the patient developed jejunal varices caused by a severe stricture in the main trunk of the portal vein. Percutaneous transhepatic portography was performed and stent-grafts were placed over the stenotic segment. A venoplasty using stent-grafts nor-malized the portal blood flow and the jejunal varices vanished. Although stenosis occurred due to scarred tissues from leakage after pancreaticoduodenectomy, stent-grafts were useful for managing jejunal bleeding post-operatively. | Toshiaki Ichihara Tsutomu Sato Hideaki Miyazawa Satoshi Shibata Manabu Hashimoto Koichi Ishiyama Yuzo Yamamoto | 2007 | World Journal of Gastroenterology2007，13，6： | 2 |
| 2 | Serum cystatin C can be used as a marker of renal function even in patients with intestinal urinary diversion显示文摘Objective:Recently,serum cystatin C(CysC)has been used as a novel marker of renal function.However,there is a lack of data on CysC levels in patients with intestinal urinary diversion(UD).Here we report CysC levels in such patients.Methods:We prospectively observed 38 patients who were diagnosed with bladder cancer and subsequently treated with radical cystectomy and UD at our institution in 2012 and 2013.Serum creatinine(sCr)and CysC were obtained optionally at the same time at least 1 month after radical cystectomy and UD.Results:The median CysC and sCr concentrations were 1.12 mg/L(range 0.75-2.47 mg/L)and 0.99 mg/dL(range 0.61-2.22 mg/dL),respectively.The median estimated concentrations of glomerular filtration rate(GFR)based on CysC(eGFRcys)and GFR based on creatinine(eGFRcreat)were 61.08 mL/min/1.73 m^2(range 22.64e99.89 mL/min/1.73 m^2)and 58.01 mL/min/1.73 m^2(range 23.48e91.82 mL/min/1.73 m2),respectively.CysC had a significant correlation with sCr(r=0.8607,p<0.0001)and eGFRcreat(r=-0.8993,p<0.0001).eGFRcys also had a significant correlation with eGFRcreat(r=0.8104,p<0.0001).Conclusion:The correlation between CysC and sCr was strong and the correlation coefficient was equivalent to that in patients without UD.The results suggest that CysC is not affected by UD and can be used as a marker of renal function similarly to sCr in patients with UD. | Masahiro Matsuki Toshiaki Tanaka Takeshi Maehana Koji Ichihara Masahiro Yanase Masanori Matsukawa Hideki Adachi Satoshi Takahashi Naoya Masumori | 2015 | Asian Journal of Urology2015，2，3： | 0 |
