Retroperitoneal leiomyosarcoma is a rare neoplasm for which complete surgical removal provides the only effective treatment, as local recurrence adversely affects prognosis. However, invasion of major vessels may occur, making complete resection difficult. This report describes the cases of three patients who required concomitant resection of parts of the inferior vena cava because of direct tumor invasion. The major vessels should be isolated in preference to the tumor capsule during surgery to prevent sudden exsanguination or incomplete tumor resection. Resection of a recurrent sarcoma or a solitary metastasis can be effective in selected patients.
腹膜后平滑肌肉瘤是一种罕见的肿瘤，对于它而言，完整的手术切除是唯一有效的治疗方法，因为局部复发会对预后产生不利影响。然而，可能会发生大血管侵犯，导致完整切除困难。本报告描述了3例因肿瘤直接侵犯而需要同时切除部分下腔静脉的患者病例。手术过程中，应优先分离大血管而非肿瘤包膜，以防止突然失血或肿瘤切除不完全。对于部分患者，复发性肉瘤或孤立性转移瘤的切除可能有效。
