摘　　要：目的 探讨旋髂深血管的嵌合穿支皮瓣移植修复四肢骨缺损合并皮肤软组织缺损的可行性和临床疗效. 方法 根据旋髂深动脉的走行及穿支分布特点,术前采用超声多普勒穿支定位,设计切取以旋髂深血管为蒂的嵌合穿支皮瓣,髂骨瓣与穿支皮瓣仅以穿支血管相连,髂骨瓣重建骨缺损,穿支皮瓣覆盖皮肤缺损创面.2008年5月至2012年6月,采用此方法治疗四肢骨缺损合并皮肤软组织缺损12例,其中车祸伤7例,重物砸伤2例,机器绞伤2例,摔伤1例;4例为急诊清创外固定支架固定后,Ⅱ期行嵌合瓣修复,8例为外院转入的开放感染创面,2例为慢性窦道流脓创面.创面细菌培养结果：大肠埃希菌2例,鲍曼不动杆菌4例,金黄色葡萄球菌3例,混合感染1例,无菌生长2例. 结果 12例皮瓣全部成活,术后切口一期愈合.术后随访6～ 18个月（平均15个月）,皮瓣质地优良,外观满意,髂骨瓣与受区骨均在8～ 10个月内获得骨性愈合,四肢功能恢复良好. 结论 吻合旋髂深血管的嵌合穿支皮瓣移植只需吻合一组母体血管,皮瓣与骨瓣仅以穿支血管相连,操作方便、血供可靠,可实现创面立体修复,是一种修复四肢骨缺损合并皮肤软组织缺损的理想方法.Objective To explore the clinical effect and experience of separating deep circumflex iliac artery osteocutaneous perforator flap （DCIAP） from the bone flap.Methods According to local applied anatomy of groin,vascularized chimerical flaps of deep iliac circumflex artery was designed and applied.From May,2008 to June,2012,12 patients who combined bone and composite skin and soft-tissue defects were positioned by color dopplar ultrasound before operation and treated with vascularized chimerical flaps of deep iliac circumflex artery.The deep circumflex iliac perforator flaps was 8 to 19 cm in length and 2 to 6 cm in width,and the iliac bone grafts ranged from 5 to 8 cm in length.Results All flaps were fully survival.After 8-10 months postoperative followed-up,all the bone defect gained healing.The function and appearance of cutaneous flaps were satisfactory.There was no serious complication in donor sites of groin.The average time of healing was 9 （8-10） months.Conclusion Vascularized iliac bone graft and a perforator flap are nourished by the same deep circumflex iliac artery.There is more mobile scope and only 1 blood vessel between the bone graft and skin flap,which should be called chimeric perforator flap based on the deep iliac circumflex artery,and is a kind of good method to repair bone and soft-tissue defects of limbs.
