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.
下腔静脉(IVC)恶性浸润常需要完全肿瘤血栓切除术和 IVC 重建。牛心包异种移植物和人工移植物常用于部分或全部 IVC 重建,具有足够的后续通畅性和无血栓形成。冷冻保存的同种主动脉移植物是替代腔静脉置换的一种选择,可在污染区域或广泛腹膜后解剖后抵抗感染。关于使用同种主动脉移植物进行 IVC 重建的具体报告很少。本文介绍了 2 例使用冷冻保存的主髂动脉同种异体移植物进行长段腔静脉修补,同时避免了广泛的腔静脉重建、移位以及需要重新植入肾静脉和肝静脉。
