Objectives: In this study, we present our surgical management strategy in inferior vena cava (IVC) vein-associated tumors and discuss clinical results. Patients and methods: Between January 2014 and December 2020, a total of 16 vein-associated tumor cases (10 males, 6 females; median age: 56.3 years; range, 39 to 69 years) operated in our clinic were retrospectively analyzed. These tumors included 10 renal cell carcinomas (RCCs), two IVC leiomyomas, one IVC leiomyosarcoma, one right subclavian vein-associated lipoma, and one tumor with IVC compression due to right renal artery aneurysm. Results: Ten of the patients were RCCs, of three were leiomyomas, of one was leiomyosarcoma, and of one was lipoma. The RCC constituted the majority of vein-associated tumors. The IVC involvement was present in all patients. Extracorporeal circulation was required in three (30%) of the RCC patients during the operation. During postoperative follow-up, venous thromboembolism development was observed in five patients, and two patients had IVC total thrombosis. Conclusion: A multidisciplinary approach, such as the approach to RCC, can be applied in the management of large vein-associated tumors with low complication and mortality rates, particularly in benign lesions.
