闭孔动脉跨区供血的长型股薄肌肌皮瓣

目的 为解决由股深动脉分支供血的股薄肌肌皮瓣因血管蒂在股薄肌中上1／3处，致使向骨盆会阴带蒂转移时距离受限的问题，探索该肌皮瓣由闭孔起始部为旋转点向骨盆会阴区域转移的方法。方法 根据闭孔动脉-旋股内侧动脉-股深动脉分支之间存在良好吻合支，设计以闭孔动脉跨区供血的长型股薄肌肌皮瓣转移的方法。这种方法可以切断股深动脉分支，使股薄肌肌皮瓣能够更松弛地转移至骨盆、外阴、耻骨、联合、腹股沟等区域。结果修复骨盆会阴区的畸形和缺损9例，所有肌皮瓣均全部成活，经术后3个月至3年的随诊，效果均满意。结论 闭孔动脉跨区供血的长型股薄肌肌皮瓣，可以作为常规的肌皮瓣在临床应用。

Longitudinal gracilis musculocutaneous flaps with a crossing boundary blood supply from the obturator artery

Objective The traditional ggracilis musculocutaneous flap is supplied by a branch of deep femoral artery, which enters the muscle in between the upper and meddle third of it. So the flap barely reaches the pelvis and perineum region for reconstruction. By exploring the blood supply pattern we tried to rotate the flap at the higher point starting at the obturator foramen in order to let it cover a bigger area. Methods Upon anatomical reviewing of the blood supply of the gracilis branches of obturator, medial femoral circumflex and deep femoral arteries. Based on this a new type of longitudinal gracilis musculocutaneous flap supported only by the obturator artery was designed to reach the pelvis, female genitalia, pubic symphysis, inguinal area easily. Results The new kind of flap has been applied to 9 patients for deformity repairing and tissue replacement in the pelvic and perineal area. All the flaps survived and achieved satisfactory result with 3 months to 3 years' follow up. Conclusions Longitudinal gracilis musculocutaneous flaps supplied by the obturator artery can be used as regular musculocutaneous flap clinically. ;
