[Diagnostic value of transjugular liver biopsy in liver transplant recipients]

Liver biopsy after hepatic transplantation essential for the correct diagnosis of grant dysfunction. However, seriously imparied coagulation or massive ascites contraindicate percutaneous liver biopsy. In these cases transjugular liver biopsy may be valid alternative. in this study the efficacy, feasibility and safety of 69 transjugular biopsies carried out in 56 liver transplant recipients are evaluated. The suprahepatic veins were catheterized in 100% of the patients and histological samples were obtained in 63 (91.3%). The number of portal tracts was greater than six in 20.6% of the samples, lower than three in 35% and oscillated between four and six in 44%. The specimens obtained were sufficient for diagnosis in 82.5% of the patients, the overall diagnostic efficacy being 75.4%. The most common histological diagnosis (28.8%) was graft damage, while rejection represented 7.7%. Only one patient (1.18%) suffered a serious complication after transjugular biopsy. Transjugular biopsy is feasible and effective in liver transplant recipients with severely imparied coagulation.
