岛状股前外侧皮瓣修复青春期后膀胱外翻腹壁缺损

The application of pedicled anterolateral thigh fasciocutaneous flap for the suprapubic defect in Post-adolescent with exstrophy of the bladder

目的:探讨一种皮瓣转移修复青春期后膀胱外翻耻骨上腹壁缺损的方法。方法:设计以旋股外侧动脉降支为血管蒂的岛状股前外侧皮瓣,掀起皮瓣后经过皮下隧道将其转移至耻骨上腹壁缺损处。对2例青春期后膀胱外翻患者,均以此法进行治疗,转移皮瓣面积为(9cm×11cm)^(10cm×15cm)。结果:临床治疗2例,转移皮瓣均成活良好,外形恢复满意。结论:青春期后膀胱外翻患者多经历数次手术修复,无局部及邻近组织可利用,岛状股前外侧皮瓣是修复耻骨上腹壁缺损的理想的远位皮瓣。

Objective：To evaluate a method for the reconstruction of suprapublc defect in postadolescent with exstrophy of the bladder by pedicle anterolateral thigh fasciocutanous flap. Methods： From January 1999 to May 2007, pedicled anterolateral thigh fasciocutaneous flap based on the perforates of lateral circumflex femoral antery had been designed and transferred to repair suprapubic defects in 2 post-adolescent patients. Results： Anterolateral thigh fasciocutaneous island flaps were performed with the size ranging from 9 cm× 11 cm to 10 cm× 15 cm. The flaps healed with satisfactory appearance. Conclusions：There is often no local and nearby flaps which can be used in post- adolescent with exstraphy of the bladder because of several previous repairs. Despite variable vascular anatomy and technical difficulties in elevating the anterolatered thigh flap, the method is a good choice in rotate flap for suprapubic defect reconstruction.
