【摘要】：目的為臨床設(shè)計以脛后動脈肌間隙穿支皮瓣提供解剖學(xué)基礎(chǔ)。方法 8例成人新鮮小腿標(biāo)本,解剖觀察脛后動脈肌間隙穿支血管及其分支的分布規(guī)律,設(shè)計以脛后動脈穿支為血管蒂的顯微削薄穿支皮瓣、聯(lián)體穿支皮瓣、穿支蒂嵌合穿支皮瓣及穿支分葉皮瓣,并模擬皮瓣切取。結(jié)果脛后動脈平均發(fā)出4.8支(3~7支)肌間隙穿支,有3支較恒定、外徑較粗的穿支分別位于內(nèi)踝上(6.7±1.1)cm、(15.8±1.8)cm和(22.6±1.7)cm處;在深筋膜下穿支可發(fā)出多支皮支、骨膜支、肌支,骨膜支的穿支主要集中在小腿中段,在同一分支點兩皮支起始外徑均≥0.5 mm的穿支主要集中在中、上段。結(jié)論在小腿中、上段的脛后動脈的第1、2穿支較恒定、外徑較粗、蒂較長及可發(fā)出多種組織分支,適合切取脛后動脈穿支蒂顯微削薄穿支皮瓣、聯(lián)體穿支皮瓣、嵌合穿支皮瓣及穿支分葉皮瓣。
[Abstract]:Objective to provide anatomic basis for clinical design of perforating branch flap of posterior tibial artery. Methods eight adult fresh leg specimens were dissected to observe the distribution of perforating branches and branches of the muscle space of posterior tibial artery. The perforating branch flap with the perforating branch of posterior tibial artery as the pedicle was designed, and the perforating branch flap was conjoined. The perforating branch flap and perforating branch flap were cut by simulated flap. Results the posterior tibial artery issued an average of 4.8 branches and 37 branches) of the intermuscular space perforating branches, 3 of which were relatively constant and the thicker perforating branches were located at 15.8 鹵1.8)cm and 22.6 鹵1.7)cm in the superior medial malleolus, respectively, and the perforating branches in the deep subfascial perforating branch could give off multiple cutaneous branches, periosteal branches and muscular branches, respectively. The perforating branches of the periosteal branches were mainly concentrated in the middle part of the leg, and the perforating branches whose starting external diameters of the two cutaneous branches were 鈮，
