Endovascular treatment of arteriovenous fistula for dialysis Aim: Aim of presented retrospective study was to evaluate the primary patency of angioplasty using a drug eluting balloon (DEB) and conventional balloon (PTA) in dysfunctional dialysis fistula. Methods: 58 adult patients treated for fistula dysfunction in the period from 2015 to 2018 were enrolled based on following criteria - matured native fistula with stenosis above 50 % compared to the adjacent healthy vein. Patients with restenosis, swing point, cephalic arch, and central vein stenosis, and multiple distant stenoses were ruled out. Patients were divided into two groups according to received treatment - DEB and PTA. Primary patency of angioplasty was defined as the function of dialysis without the need for clinically driven endovascular or surgical intervention on culprit lesion during follow-up. Secondary, dialysis access patency, 12-month assisted patency, technical, clinical success, complication rate, and mortality among treated groups were evaluated. Results: Primary patency at 6 and 12 months follow up was evaluated in 25 patients in the DEB and 25 patients in the PTA group. Primary lesion and access patency were in DEB vs. PTA: 96 % vs. 76 % (p = 0,1) and 96 % vs. 72 % (p = 0,049) at 6 months, 80 % vs. 56 % (p = 0,13), 80 % vs....

The role of imaging methods and interventional radiology in liver transplantation programme: transarterial chemoembolization of hepatocellular carcinoma and therapy of vascular and biliary complications after orthotopic liver transplantation.
Laštovičková, Jarmila ; Peregrin, Jan (advisor) ; Köcher, Martin (referee) ; Hořejš, Josef (referee)
121 9. Summárý Purpose: This study was designed to evaluate the role of interventional radiology in liver transplantation programme. The aim is to present our experience, technical outcomes and long-term clinical results with chemoembolization of hepatocellular carcinoma in patients before liver transplantation and with percutaneous treatment of vascular and biliary complication after orthotopic liver transplantation. Methods: Twenty five patients (17 men, 8 women, mean age 57.76 years) with HCC were scheduled for TACE prior to liver transplantation from 2008 to 2012. Twenty three procedures were performed, 7 c-TACE in 2008 and 16 DEB TACE in next years. Thirty patients (13 men, 17 women, mean age 46.4 years) with biliary strictures after liver transplantation without endoscopic access possibility were treated with balloon dilatation and biliary duct drainage from 1996 and 2010. Twenty patients (13 men, 7 women, mean age 45.25 years) were treated with PTA/stent due to hepatic artery stenosis after liver transplantation between 1996 and 2011. Stents were placed to the hepatic/celiac artery in 16 PTAs, balloon dilatation alone was performed in 7 stenosis due to tortuosity of the vessel. Results: Liver transplantation was performed to 20 patients after TACE. Only one patient (4.5 %) was excluded from waiting...
