改良腹壁下动脉穿支皮瓣的临床应用

目的 探讨腹壁下动脉穿支皮瓣(deep inferior epigastric perforator flap,DIEP皮瓣)切取方式的改进,扩大DIEP皮瓣的临床应用范围.方法 采用双腹壁下血管蒂仅带肌袖的DIEP皮瓣(并可通过筋膜蒂携带髂骨或肋骨)修复四肢大面积软组织缺损,其中前臂缺损5例,手腕部缺损6例,创面面积为10.0 cm×5.0 cm～45.0cm×20.0 cm,均为急诊修复.结果 术后11例皮瓣中全部存活10例,大部分存活1例.随访时间3～61个月,皮瓣愈合良好,手功能恢复满意.所有供区均未发生腹壁疝.结论 改良DIEP皮瓣是修复大面积皮肤缺损的首选皮瓣之一.

Clinical application of modified deep inferior epigastric perforator flap

Objective To improve the techniques of harvesting the deep inferior epigastric perforator (DIEP) flap and broaden the clinical application of the flap. Methods A modified DIEP flap (or DIEP osteofasciocutaneous flap with iliac or rib) involving perforating vessels of the bilateral deep inferior epigastric vasculature with a muscle cuff was used to cover large defects of the extremities. There were 5 cases of defects of the forearm and 6 cases with defects of the hand and wrist. The areas of the defects were 10.0 cm × 5.0 cm to 45.0 cm × 20.0 cm. All flap transfers were done in the emergent setting. Results 10 of the 11 flaps survived completely while one flap survived with partial necrosis. Follow up ranged from 3 to 61 months. The flaps healed well. Function of the hand was satisfactory. There was no abdominal wall hernia at the donor sites. Conclusion The modified DIEP flap involving bilateral pedicles is the procedure of option for reconstruction of large defects.
