目的为膝下外侧动脉远端蒂腓骨头瓣移植提供解剖学基础。方法在30侧经动脉内灌注红色乳胶成人下肢标本上重点观测膝下外侧动脉发出腓骨头支近端及远端的长度及外径,另在1侧新鲜标本上进行摹拟手术设计。结果膝下外侧动脉始于腘动脉,近端长(4.1±0.5)cm,外径(1.8±0.2)mm,远端长为(5.3±0.4)cm,外径为(1.0±0.1)mm。结论以膝下外侧动脉远端为蒂的腓骨头瓣,较近端为蒂损伤小、操作简便等优点。
Objective To provide an anatomical basis for the distal pedicled pedicle fibular head flap transplantation. Methods The length and diameter of the proximal and distal branches of the fibular head were observed on the lower extremity of the adult lower extremity arteries by injection of red latex on the 30th side of the adult. The mock surgery design was also performed on the fresh side of the 1 case. Results The inferior genicular artery originated from the popliteal artery, with a length of (4.1 ± 0.5) cm at the proximal end and a diameter of (1.8 ± 0.2) mm on the proximal end. The distal length was (5.3 ± 0.4) cm and the outer diameter was (1.0 ± 0.1) mm. Conclusion The distal pedicle of the lateral hypothalamic pedicle fibular head flap, compared with the proximal pedicle injury, simple operation and so on.
