Abstract

Background: Primary leiomyosarcoma of the inferior vena cava (IVC) is a rare soft tissue sarcoma. Techniques for caval reconstruction after tumor resection vary widely. Our single-center experience serves as one of the largest reviews of caval reconstruction using polytetrafluoroethylene (PTFE) interposition grafts published in the past 10 years. Methods: We conducted a single-center retrospective review of all patients who had undergone surgical resection of IVC leiomyosarcomas since January 1, 2007. Information regarding the procedure and patient-specific data was obtained from the institution's electronic medical record. Results: We identified 4 patients (3 women and 1 man) who had undergone surgical resection for IVC leiomyosarcoma with PTFE graft reconstruction. Adjunct procedures (i.e., arteriovenous fistulas) were not used to maintain graft patency. There was no perioperative mortality within our patient population. One patient returned within 30 days with an acute kidney injury associated with a partially occlusive thrombus in the proximal part of the PTFE conduit. Another patient was found to have infolding of the PTFE graft due to inappropriate graft oversizing at the time of the index operation. Two patients developed distant metastases within a year of surgery, despite having tumor-free margins at the time of the initial operation. All the PTFE interposition grafts remained patent throughout the follow-up without the need for an additional intervention. Conclusions: PTFE interposition graft may be a safe and effective conduit for caval reconstruction after resection of a primary leiomyosarcoma of the IVC, but further research is necessary to establish appropriate management guidelines.
