Abstract    Surgery treatment of complex retroperitoneal tumor invading major vein is complicated because of the risk of uncontrollable bleeding. To raise the excision rate and decrease the recurrence rate, many procedures can be used. The  sensitivity and specificity of preoperative imaging examination are effective for planning surgical procedures. With vascular surgery techniques, the invaded major veins can be isolated, resected or reconstructed. Appropriate postoperative treatments, including anticoagulation therapy, are significant for long-term patency of the invaded major veins and avoidence of distal organ reflux disorder, which contribute to improve the resection rate and postoperative quality of life.
