解剖观测了30侧成人下肢足内侧区皮肤血管.足底内侧动脉深支、浅支、内踝前动脉和跗内侧动脉,分别发4.5(3～8)支、7.4(3～12)支、5.9(2～12)支和2.8(1～6)支,外径在0.2～0.8mm之间的皮支分布足内侧区,动脉间吻合恒定.经选择性动脉注射显示,皮瓣面积约为9×6cm～10×8cm.以上述动脉为蒂的足内侧皮瓣,可转位修复内踝、跟腱、足跟和足底远侧区的软组织缺损,临床应用了12例均获得成功. The skin vessels in the medial region of lower extremities of 30 adult adults were dissected, including deep branches of the medial plantar pedis, superficial branches, anterior malleolus and medial malleolus, with 4.5 (3-8) branches, 7.4 (3-12) branches, 5.9 (2 ~ 12) branches and 2.8 (1 ~ 6) branches, the outer diameter of 0.2 ~ 0.8mm between the branch distribution of the medial foot area, constant anastomosis between arteries .Selective arterial injection showed flap area of ​​about 9 × 6cm ~ 10 × 8cm. The medial pedicle pedicle flap can be transplanted to repair the soft tissue defect of the medial malleolus, Achilles tendon, heel and the plantar distal region, all of which have been successfully applied in 12 cases.
