Malignant invasion of the inferior vena cava (IVC) often necessitates complete tumor thrombectomy and IVC reconstruction. Bovine pericardial xenografts and prosthetic grafts are frequently used for partial or entire IVC reconstruction with adequate subsequent patency and freedom from thrombosis. Cryopreserved aortic homografts represent an alternative conduit for vena cava replacement with resistance to infection in contaminated fields or following extensive retroperitoneal dissection. Specific reports of aortic homograft use for IVC reconstruction are scarce. Described are 2 cases of cryopreserved aortoiliac artery allograft use for long segment cava patch repair while avoiding extensive caval reconstruction, mobilization and the need for renal vein and hepatic vein re-implantation.
