摘要
目的 :为带血管神经蒂股薄肌瓣转位重建尿道括约肌术提供解剖学基础。方法 :在 35例成人下肢标本上 ,对股薄肌的形态、主要血管、神经的来源 ,血管神经蒂的长度、入肌部位等进行解剖观测。结果 :股薄肌全长 (42 .0± 0 .6 )cm ,肌腹长 (31.0± 3 .8)cm ;肌腱长 (10 .9± 0 .9)cm ;股薄肌的血供主要来源于股深动脉的股薄肌支 ,该分支起始处外径 (2 .1± 0 .6 )mm ,血管蒂长 (9.2± 0 .9)cm ,入肌部位在股薄肌中、上 1/3交界处前缘的深面 ;股薄肌的神经支配 ,均恒定地来自闭孔神经前支 ,该神经在闭膜管处 ,横径为(1.7± 0 .4)mm ;厚 (0 .5± 0 .2 )mm ,从闭膜管至入肌点处长 (10 .4± 1.4)cm。结论 :带血管神经蒂股薄肌瓣转位重建尿道括约肌术 ,经尸体摹拟实验 ,证明具有可行性。
Objective: To provide anatomic basis for the reconstruction surgery of sphincter of urethra using gracilis flap pedicled with vessels and nerves.Methods: On 35 adult upper extremity specimens, the shapes, main blood vessels and nerves of gracilis, the length of pedicle and the position where the vessels and nerves entered the muscle were dissected and measured.Results: (1)The lengths of gracilis, muscle belly and tendon were 42.0±0.6 cm, 31.0±3.8 cm, 10.9±0.9 cm respectively; (2) The blood supply of gracilis originated mainly from the gracilis branch of deep femoral artery, the outer diameter of this branch origin was 2.1±0.6 mm, the length of vessel pedicle was 9.2 ±0.9 cm; (3) Gracilis was innervated by the anterior branch of obturator nerve, the transverse diameter of the nerve in the obturator canal was 1.7±0.4 mm, thickness was 0.5±0.2 mm, the distance from the obturator canal to the site where it enter the gracilis was 10.4±1.4 cm. Conclusion: The transposition surgery of gracilis pedicled with vessels and nerves for the reconstruction of sphincter of urethra is feasible.
