目的：报道切取旋髂深动脉（ＤＣＩＡ）髂骨复合瓣移植供区并发症前瞻性临床研究结果。方法：３８例下颌骨缺损患者共进行４０例ＤＣＩＡ髂骨复合瓣移植，对供区并发症及感觉、运动功能障碍进行手术前后连续追踪评价。结果：供区疼痛，感觉与步态障碍为术后普遍而暂时的并发症；伤口迁延不愈、腹疝、股神经麻痹等并发症发生率较低；供区长期痛可能与神经嵌压及牵拉损伤有关。结论：ＤＣＩＡ髂骨复合瓣移植供区并发症是可以接受的，但应严格掌握手术指征，重视技术操作
OBJECTIVE: To report the results of a prospective clinical study on the complications of grafting the iliac bone graft with deep iliac arteries (DCIA). Methods: Forty - eight patients with mandibular defect underwent a total of 40 cases of DCIA iliac composite flap transplantation. The complication, sensory and motor dysfunction were evaluated continuously before and after operation. Results: The donor site pain, sensory and gait disorders were the common and temporary postoperative complications. The delayed wound healing, low incidence of complications such as ventral hernia and femoral nerve paralysis were associated with long-term pain and nerve entrapment and Stretch injury related. Conclusion: DCIA ilium composite flap transplantation for regional complications is acceptable, but should strictly grasp the indications for surgery, attention to technical operation
