Inferior Vena Cava-Atrial Anastomosis in Liver Transplant Recipient with Inferior Vena Cava Occlusion: A Case Report and Literature Review.

ABSTRACT: A 25-year-old woman with decompensated liver cirrhosis and complete inferior vena cava (IVC) occlusion was referred to our department for liver transplantation. The etiology of cirrhosis was Budd-Chiari syndrome (BCS) related to systemic lupus erythematosus, autoimmune hepatitis, and primary biliary cholangitis (AIH-PBC) overlap syndrome. Transplantation was feasible due to an extensive collateral circulation of pre-vertebral veins that drained blood from the lower extremities and both kidneys to the azygos-hemiazygos veins. This venous anomaly enabled the excision of the obstructed retrohepatic IVC, followed by an alternative anastomosis of the suprahepatic IVC to the right atrium without reconstruction of the infrahepatic IVC. Despite good venous patency and normalization of liver graft
