BACKGROUND: Caval replacement after circumferential resection of the inferior vena cava remains controversial. The aim of the current study is to determine whether or not inferior vena cava replacement should be performed. METHODS: We reviewed 36 cases undergoing resection of the inferior vena cava concomitant with resection of malignant neoplasms. Our criteria for circumferential resection of the inferior vena cava were half or more of the circumference of the vessel wall invaded by tumor, a primary tumor of the caval wall, or massive intraluminal tumor thrombus suspected of adhering to the caval wall. We detailed 10 patients undergoing circumferential resection of the inferior vena cava. RESULTS: Most of patients who did not undergo replacement of the inferior vena cava showed no sign of swelling of the lower limbs, but one showed persistent leg edema with oliguria. This patient had poor development of collateral circulation and mild obstruction of the inferior vena cava before surgery. Two patients who underwent replacement of inferior vena cava had no venous sequelae, although they had poor development of collateral circulation before surgery. CONCLUSION: Caval replacement after circumferential resection of the inferior vena cava may be necessary in patients who have preoperative poor development of collateral circulation or who have oliguria or unstable hemodynamics intraoperatively.
