    Abstract:
    The aim of this study was to analyse vascular complications (VC) accompanying the introduction in Estonia of orthotopic liver transplantation (OLT) for treatment of end-stage liver disease. We present the incidence and treatment of VC occurring among our first 23 OLT in 22 patients. The 11 female and 11 male patients were aged 12 to 67 years. Their diagnoses were cholestatic disease (n = 8); hepatitis C virus (HCV) cirrhosis (n = 6); tumor (n = 3); Budd-Chiari syndrome (n = 2); autoimmune hepatitis (n = 1); cystic fibrosis (n = 1); or fulminant hepatic failure (n = 1). Only end-to-end vascular reconstructions were used in OLT. The patients' 1-year post-OLT survival rate was 86%. VC were confirmed using computed tomography (CT) or magnetic resonance imaging (MRI). In cases of VC, we started a 1-week course of subcutaneous anticoagulant therapy with low-molecular weight heparin (LMWH) immediately followed by permanent oral treatment. The incidence of VC was 14% (n = 3). There was no hepatic artery thrombosis. One patient developed hepatic venous thrombosis at 3 weeks after retransplantation. She was treated successfully with immediate LMWH followed by a permanent oral anticoagulation. Two patients experienced portal vein complications: 1 with pre-OLT portal vein thrombosis developed right intrahepatic portal vein thrombosis at 5 weeks after OLT requiring portal thrombectomy. He was treated successfully with immediate LMWH followed by permanent oral anticoagulation. The other subject displayed left intrahepatic portal vein thrombosis at 1 week after OLT. Despite immediate LMWH treatment followed by a permanent oral anticoagulation, he required left lobe necrectomy and Roux-Y choledochojejunostomy for recovery. The survival and recovery of all studied patients with VC allow us to recommend immediate subcutaneous anticoagulant therapy for post-OLT portal or hepatic venous thrombosis.
