胸腹壁随意皮瓣联合腹直肌肌瓣修复胸壁缺损

目的探讨胸腹壁随意皮瓣联合腹直肌肌瓣移位修复胸壁缺损的临床应用价值。方法2002年1月～2005年6月,对5例胸壁缺损患者行胸腹壁随意皮瓣联合腹直肌肌瓣移位修复术。其中胸骨骨髓炎术后、胸骨肿瘤刮除术后、胸骨结核病灶清除术后各1例,心脏手术术后2例;均因感染致胸骨及内置物外露,病程6个月～2年。先行病灶清除,视创面大小设计切取15cm×10cm的胸腹壁随意皮瓣,然后切取腹直肌肌瓣移位修复胸壁缺损。结果术后4例皮瓣期愈合,1例皮瓣延期愈合,无并发症。皮瓣外观良好,无臃肿及色素沉着,X线片显示胸骨死骨阴影消失。随访1～3年,平均1年6个月,无复发。腹部供区皮肤愈合良好,无腹壁疝发生。结论胸腹壁随意皮瓣联合腹直肌肌瓣移位修复术是治疗胸骨体周围胸壁缺损的一种简单、有效方法,值得推广应用。

REPAIR OF DEFECTS IN CHEST WALL WITH THORACICO-ABDOMINAL SKIN FLAP AND MUSCLE FLAP OF MUSCULUS RECTUS ABDOMINIS

OBJECTIVE: To evaluate the application value of repairing the defects of the chest wall with the thoracico-abdominal skin flap and the muscle flap of the musculus rectus abdominis. METHODS: From January 2002 to June 2005, five patients with defects in the chest wall underwent the prothesis with the thoracico-abdominal skin flap and the muscle flap of the musculus rectus abdominis under general anesthesia. Focal cleaning was performed first; then, the skin flap was designed and taken (15 cm x 10 cm); and finally, the defects of the chest wall were repaired with the muscle flap of the musculus rectus abdominis. RESULTS: Of the 5 patients, 4 had the flap healing by the first intention, and 1 had the delayed healing, with no complication. The skin flap had a good appearance, without edema or pigmentation. The X-ray examination showed that the shadow of the sternal sequestrum disappeared. There was no recurrence or complication during the follow-up for 1-3 years (average, 18 mon). CONCLUSION: The repairing of the defects in the chest wall with the thoracico-abdominal skin flap and the muscle flap of the musculus rectus abdominis is a simple and effective surgical treatment for defects of the chest wall around the sternum, and this kind of treatment is worth applying extensively in clinical practice.
