ABSTRACT

Objective To evaluate surgical treatment for different types of tumor of the suprarenal infrahepatic segment of the inferior vena cava (IVC).Methods A retrospective analysis was made on 8cases of IVC leiomyosarcoma at the suprarenal infrahepatic IVC segment.According to the extent of tumor invasion and collateral circulations,operations included tumor resection plus inferior vena cava reconstruction or tumor resection plus right nephrectomy.Results Tumors were completly resected in all patients.Renal function recovered after operation.During a follow up of 24 mons,7 cases had no recurrence.One case with recurrence after 12 months underwent successful resection and is doing well after a follow-up of 12 months.Conclusion CT and inferior vena cavography can determine the extent of tumor invasion and collateral circulations helping select appropriate surgical aproach before the operation resulting in less renal injury.
