带血管蒂的足外侧肌皮瓣的应用解剖研究

Applied anatomical studies on the pedicled lateral pedal musculocutaneous flap

目的 :为足部软组织缺损的修复提供解剖学基础。方法 :对 6 8例新鲜成人下肢标本分别用红色乳胶、ABS,以及 10 %明胶硫酸钡墨汁混悬液进行血管灌注 ,经血管造影、X线摄片和显微解剖的方法 ,进行观测和研究。结果 :足外侧肌皮瓣的血供可有腓动脉的穿支或跗外侧动脉保证。其中腓动脉穿支的外径为 1.2± 0 .3( 0 .5～ 2 .1)mm ,跗外侧动脉的外径为 0 .9± 0 .2 ( 0 .5～ 1.8) m m。结论 :根据不同部位的需要可选择不同的带血管蒂的足外侧肌皮瓣 ,以修复足部软组织的缺损。

Objective: To provide the anatomical basis for the repair of the soft tissue defects on the dorsum of the foot. Methods: Sixty eight low extremity specimens were taken from fresh cadavers. The arterial distributions of the foot were observed by perfusing red latex, barium sulfate, Chinese ink and 10% gelatin, also studied by X ray angiography and microdissection. Results: The blood supply of the lateral pedal region was ensured by the lateral tarsal artery and perforating branch of the peroneal artery. The external diameter of the lateral tarsal artery was 0.9±0.2(0.5～1.8)mm while external diameter of the perforating branch of the peroneal artery was 1.2 ± 0.3 (0.5～2.1)mm. Conclusion: The lateral pedal musculocutaneous flap can be devised according to the different repair regions to restore the defected soft tissues of the foot.
