This study reports the surgical management and outcomes of patients with malignancies affecting the IVC.
This was a retrospective study that considered patients undergoing surgery for IVC thrombectomy in Calgary, Canada, from 1 January 2010 to 31 December 2021. Parameters of interest included primary malignancy, the extent of IVC involvement, surgical strategy, and medium-term outcomes.
Six patients underwent surgical intervention for malignancies that affected the IVC. One patient had a retroperitoneal leiomyosarcoma, 1 had hepatocellular carcinoma with thrombus extending into the IVC and right atrium, 1 had adrenocortical carcinoma with IVC thrombus extending into the right atrium, and 3 had clear cell renal cell carcinoma with thrombus extending into the IVC. Surgical strategy for the IVC thrombectomy varied where 5 patients required the institution of cardiopulmonary bypass and underwent deep hypothermic circulatory arrest. No patient died perioperatively. One patient died 15-months post-operatively from aggressive malignancy.
Different types of malignancy can affect the IVC and surgical intervention is usually indicated for these patients. Herein, we have reported the outcomes of IVC thrombectomy at our center.
本研究报告了影响下腔静脉（IVC）的恶性肿瘤的手术治疗和结果。
这是一项回顾性研究，纳入了 2010 年 1 月 1 日至 2021 年 12 月 31 日期间在加拿大卡尔加里接受 IVC 血栓切除术的患者。感兴趣的参数包括主要恶性肿瘤、IVC 受累程度、手术策略和中期结果。
6 名患者因恶性肿瘤影响 IVC 而行手术干预。1 例为腹膜后平滑肌肉瘤，1 例为肝细胞癌合并血栓延伸至 IVC 和右心房，1 例为肾上腺皮质癌合并血栓延伸至右心房，3 例为透明细胞肾细胞癌合并血栓延伸至 IVC。IVC 血栓切除术的手术策略各不相同，其中 5 例需要建立体外循环并进行深低温循环停止。无患者围手术期死亡。1 例患者术后 15 个月死于侵袭性恶性肿瘤。
不同类型的恶性肿瘤可影响 IVC，通常需要对这些患者进行手术干预。本文报告了我们中心的 IVC 血栓切除术结果。
