Abstract

Background: Retroperitoneal leiomyosarcomas are aggressive malignancies. Complete surgical resection with negative margins is crucial to decrease the risk of recurrence but can be risky due to vascular involvement. The aim of our study was to evaluate the different approaches to IVC and renal vein management and their impact on postoperative complications.

Methods: We performed a retrospective review of patients who underwent surgery for retroperitoneal leiomyosarcoma with IVC and/or renal vein involvement at our institution from 2016 to 2024. Patients were stratified by intraoperative vascular management, including ligation only versus varying forms of vascular reconstruction. Postoperative complications, including bleeding, transfusions, the need for acute and chronic hemodialysis, and thromboembolic events, were recorded. Chi-squared tests were used to compare rates of postoperative complications by vascular management. A p-value of 0.05 was considered statistically significant.

Results: We identified 60 patients at our institution who underwent surgery for leiomyosarcoma with IVC and/or renal vein involvement. Ten patients underwent IVC ligation alone due to thrombosis, thirty-six had IVC replacement, and fourteen had patch angioplasty. In the entire cohort, twenty-six patients (43.3%) experienced an adverse event after surgery. When looking at postoperative adverse events by IVC management, we did not find any statistically significant differences among rates of adverse events by group. There were also no statistically significant differences in complications following renal vein ligation versus renal vein reconstruction.

Conclusions: Patients with leiomyosarcoma with IVC and/or renal vein involvement have several options for intraoperative vascular management. Our data demonstrates that there are no statistically significant differences in rates of complications among the different groups.
