OBJECTIVE: The aim: To improve the outcomes of inferior vena cava (IVC) leiomyosarcoma, propose own classification of IVC segments, which correlates with surgical access, methodology, sequence and amount of surgery.
PATIENTS AND METHODS: Materials and methods: In the period from 1991 to 2021 in the Transcarpathian Regional Clinical Hospital named after A. Novak and in the Transcarpathian Antitumor Center 8 patients with IVC leiomyosarcoma were operated. The prevalence of leiomyosarcoma in IVC was determined according to the division of IVC into 7 segments. Defeat of one segment of IVC was in 50% of cases, two - in 37.5%, three - in 12.5%. In 5 (62.5%) cases circular resection and alloprosthesis of IVC were performed; in 2 (25%) - circular resection, alloprosthesis of IVC and implantation of the right and left renal veins in the prosthesis; in 1 (12.5%) - circular resection, alloprosthesis of IVC and implantation of the left renal vein in the prosthesis. All surgeries were performed with laparotomy access (87.5% by Chevron type).
RESULTS: Results: The average operation time was 215 (160-320) minutes, the average blood loss was 305 (250-500) ml. Postoperative complications were recorded in 2 (25%) cases. There were no cases of pulmonary embolism, venous thrombosis, prosthesis thrombosis, perioperative mortality. In 7 (87.5%) cases, surgery was radical. The overall 1-year, 2-year and 3-year survival rates were 87.5%, 71.4% and 57.7%.
CONCLUSION: Conclusions: The division of IVC into 7 segments characterizes the detailed definition of the cranial limit of leiomyosarcoma and segmental involvement of IVC in the tumor process, which allows to choose the right surgical tactics, perform radical resection of IVC and maintain laminar blood flow to IVC and its tributaries.
