title: Interventional radiologic procedures in the treatment of complications after liver transplantation.
abstract: The aim of this study is to report our interventional radiologic procedures (IRP) in liver transplant (LTX) patients. These include procedures for biliary, arterial, venous, and portal complications, as well as the treatment of infected and non-infected fluid collections. This retrospective study covered 583 patients (mean age: 44 +/- 14 yr) in whom a total of 685 LTX were performed from August 1987 to April 2005. Overall, 182 LTX patients underwent a total of 428 IRP, including digital subtraction angiography (n = 152/35.51%), percutaneous transluminal angioplasty (PTA) (n = 4/0.93%) and PTA + stent (n = 7/1.63%) of arterial anastomosis, PTA + stent of the celiac trunk (n = 2/0.46%), transjugular intrahepatic portosystemic shunt (TIPS) (n = 2/0.46%), arterial lysis (n = 4/0.93%), venous lysis (n = 2/0.46%), inferior vena cava stenting (n = 2/0.46%), percutaneous biliary drainage (n = 34/7.94%), percutaneous transluminal dilatation (PTD) of the choledocho-enteric anastomosis (n = 16/3.73%), biliary stent (n = 5/1.16%), intrahepatic biliary flushing treatment, stone and cast biliary extraction (n = 27/6.30%), other interventions (e.g., embolization in other regions, transjugular liver biopsies, lymphangiographies) (n = 9/2.10%), and ultrasound- and computer tomography-guided biopsies and percutaneous drainage (n = 153/35.74%). The overall success rate was 85.7%. Technical improvements in LTX and interventional radiology permit vascular and biliary complications to be treated successfully by interventional radiology.
