Background: Safe resection of intraabdominal and retroperitoneal malignancies with a goal of negative margins may require vascular surgical assistance with grafting of the aorta and/or vena cava. The current report reviews malignancies associated with major vascular reconstructions at a single tertiary referral center. Methods: Adults with abdominal or retroperitoneal tumors involving the aorta, vena cava, or iliac arteries that underwent reconstruction with vascular grafts at the University of Michigan from 2010 to 2016 were reviewed retrospectively. The initial presentation, surgical management, and outcomes were analyzed. Results: Twelve patients with tumors involving the abdominal aorta, vena cava, or iliac arteries underwent major vascular reconstruction in this seven-year study period. Tumor pathology included solid tumors (leiomyosarcoma [n = 7], germ cell tumor [n = 3], and intravascular lymphoma [n = 2]). Surgical treatment included grafting of the vena cava (n = 6), aorta (n = 3), iliac artery (n = 4), or both the aorta and vena cava (n = 1). Patients with intravascular lymphoma were identified incidentally during treatment of abdominal aortic aneurysm or on pathological analysis of thromboembolism from an aortic source. Other patients had planned resection. Follow-up ranged from 9 to 86 months (median: 28.9). There were no graft occlusions. Tumor metastasized or recurred in patients with sarcoma (n = 2; 28.6%), germ cell tumor (n = 1; 33.3%), and intravascular lymphoma (n = 2; 100%). Both patients with lymphoma had multiple anastomotic or tumor-embolic pseudoaneurysms for <14 months after vascular reconstruction. Both lymphoma patients died during follow-up. Conclusions: This single-center review suggests that sarcoma and germ cell tumors may be safely resected in conjunction with major vascular reconstruction in carefully selected patients. In comparison, intravascular lymphoma identified incidentally at the time of aortic reconstruction resulted in a more malignant course with pseudoaneurysm formation of anastomoses or native vessels, cancer recurrence, and 100% mortality. Aneurysm contents and emboli should be carefully reviewed perioperatively by pathologists.
