Background: Involvement of the inferior vena cava (IVC) by neoplasm has traditionally been considered a contra-indication to curative surgery because of high surgical risks and poor long-term prognosis. Advances in surgical and anaesthetic techniques however have made this feasible. The aim of this study is to evaluate the outcome of combined IVC and visceral resection in a single institution.
Methods: A retrospective review of a prospectively maintained database was performed. Pre-operative clinicopathological data, operative details and post-operative outcomes including overall and disease-free survival were analysed. Clinicopathological data of patients over a seven-year period undergoing combined IVC and visceral resection was reviewed, including overall and disease-free survival.
Results: Between 2006 and 2012, 14 patients underwent IVC resection was accompanied by major hepatectomy (8), nephrectomy (6) and multivisceral resection (3). Post resection, the IVC was reconstructed primarily (3); with PTFE tube graft (9) or using a Gore-tex patch graft (2). All patients underwent a R0 resection. There were two postoperative deaths within 30 days. 6 patients had postoperative complications. There was 1 early and one late (after 6 months) IVC thrombosis. With a median follow up of 20 months (range 5-84 months), two patients died of tumour recurrence and ten are alive with (n = 5) or without (n = 5) disease.
Conclusion: Combined IVC and visceral resection can be safely performed in selected patients. Surgery provides the possibility of negative margins, acceptable perioperative morbidity/mortality and prolonged survival. These factors combined with lack of alternative treatments justify this approach. However, specialist teams should perform the surgery preferably in centres with expertise in liver transplantation.
