目的介绍上腹部双叶带蒂瓦合皮瓣修复手、前臂掌背侧皮肤缺损的方法及疗效。方法 2010年10月-2013年12月,收治4例手、前臂掌背侧皮肤软组织缺损男性患者,年龄36~62岁。其中机器伤致手部皮肤脱套伤3例,挤压伤术后皮肤、手指坏死1例;伤后至入院时间3 h^15 d。4例彻底清创后,软组织缺损范围掌侧7 cm×4 cm^16 cm×6 cm,背侧10 cm×7 cm^20 cm×10 cm。以腹壁下动脉与腹壁上动脉和肋间动脉交通形成的轴型血管为解剖学基础,设计上腹部双叶带蒂瓦合皮瓣修复创面。皮瓣切取范围垂直向12 cm×4 cm^18 cm×6 cm,斜向15 cm×8 cm^22 cm×11 cm。供区直接拉拢缝合。修复术后22~24 d行断蒂术。结果术后4例皮瓣均顺利成活,切口Ⅰ期愈合。患者获随访3个月~1年2个月。除1例皮瓣外形略臃肿外,其余皮瓣外形、质地均良好;皮瓣感觉恢复至S2~S3。手部功能恢复良好。结论对于手、前臂掌背侧皮肤软组织缺损患者,可应用上腹部双叶带蒂皮瓣顺利修复。该皮瓣切取面积大,血供来源可靠,是一种实用、安全且简便的手术方式。

Objective To introduce the surgical method and effectiveness of repairing skin and soft tissue defect in the palm or dorsum of the hand and forearm with epigastric bilobed flap. Methods Between October 2010 and December 2013, 4 male patients with skin and soft tissue defect in the palm or dorsum of the hand and forearm were treated, aged from 36 to 62 years. Of them, 3 cases had degloving injury caused by machines and 1 case had necrosis of fingers and skin after surgery of crush injury. The time from injury to hospitalization was from 3 hours to 15 days. Among the 4 cases, the size of palmar defect was 7 cm×4 cm to 16 cm×6 cm, and the size of dorsal defect was 10 cm×7 cm to 20 cm×10 cm. The epigastric bilobed flap was designed based on the axial vessel which was formed by inferior epigastric artery, superior epigastric artery, and intercostals arteries. The size of flap ranged from 12 cm×4 cm to 18 cm×6 cm in the vertical direction, 15 cm×8 cm to 22 cm×11 cm in the oblique direction. The donor site was directly closed. The pedicles were cut at 22 to 24 days after repairing operation. Results All the flaps survived well with the wound healing by first intention. Four patients were followed up 3 months to 1 year and 2 months. The other flaps had good appearance and texture except 1 bulky flap. The flap sensation basically restored to S2-S3. The function of the hands recovered well. Conclusion Skin and soft tissue defect in the palm or dorsum of the hand and forearm can be repaired with the epigastric bilobed flap, because it has such advantages as big dermatomic area and adequate blood supply. Besides, the operation is practical, safe, and simple.
