BACKGROUND.: METHODS.: Twenty-seven patients undergoing operative resection of a venous LMS at a single tertiary care center and one secondary care hospital were reviewed retrospectively and divided into 2 groups: IVC-LMS (Group A, n = 18) and non-IVC LMS (Group B, n = 9). As primary end points, postoperative mortality and morbidity, disease-specific survival and, if applicable, patency of venous reconstruction were considered. Bivariate differences were compared with the χ test. Disease-specific survival was expressed by a life-table analysis and compared using the log-rank test. RESULTS.: No postoperative mortality was observed in either group. Postoperative morbidity was 28% in group A and 11% in group B (P = .33). The mean duration of follow-up was 60 months (range, 13–140). Disease-specific survival was 60% in group A and 75% in group B at 3 years (P = .48), and it was 54% in group A and 62% in group B at 5 years (P = .63). Seven grafts were occluded in group A (39%) and 1of 3 were occluded in group B (33%) (P = .85). CONCLUSION.
