A resected case of leiomyosarcoma of the Inferior Vena Cava

A 52-year-old female who presented with abdominal pain had undergone laparotomy at another hospital and been diagnosed as having a tumor of the IVC. She underwent reoperation at our hospital. The tumor arose from the IVC wall and extended into the right renal vein. The IVC patency was maintained. First, the right renal vein was anastomosed to the IVC using an autologous graft (saphenous vein), and then the tumor was completely resected along with a segment of the IVC wall. The IVC was reconstructed using an EPTFE graft. During the IVC resection and reconstruction, the IVC was clamped for 43 min. without any bypass. No remarkable changes in blood pressure or congestion were observed. The postoperative course was uneventful and the patient was discharged on the 18th postoperative day. Histological diagnosis was leiomyosarcoma of the IVC. Six months later, the patency of the IVC graft was still maintained. In Japan, ours is the 53th case report, and the 12th with resection and econstruction of the IVC.
