    Abstract:
    OBJECTIVES: This study sought to evaluate the indications, techniques, and results of inferior vena cava (IVC) replacement at living donor liver transplantation (LDLT). MATERIALS AND METHODS: We performed 821 LDLTs and 11 (1.3%) patients required concomitant IVC replacement. We analyzed the indications, replacement materials, and outcomes. RESULTS: Right, left, and left lateral liver lobes were transplanted in 7, 2, and 2 patients, respectively. The indications for IVC replacement were thrombosis/fibrosis in 7 patients (Budd-Chiari 4, hereditary tyrosinemia 1, congenital hepatic fibrosis 1, cryptogenic 1), involvement with mass in 3 patients (Echinococcus alveolaris 2, hepatoblastoma 1) and iatrogenic narrowing at IVC in 1 patient. Cryopreserved grafts (aorta n = 5, IVC n = 4, iliac vein n = 1) or synthetic graft (n = 1) were used for replacements. In 1 patient, hepatic outflow obstruction developed at 39 days and was treated successfully by interventional radiology. There was only 1 hospital mortality (8.9%) that was unrelated to caval replacement (subarachnoid hemorrhage). Of the remaining patients, the caval grafts were patent after a mean 7.7 months of follow-up (range 1 to 17 months). CONCLUSIONS: Although rare, IVC replacement can be necessary at LDLT. Budd-Chiari and E. alveolaris are the main underlying diseases for replacement requirements. Caval replacement with cryopreserved vascular grafts can provide successful short-term and long-term patency.
