摘要
目的:设计以腘窝中间皮动脉为蒂的岛状皮瓣。方法:通过对10侧新鲜成人下肢标本的显微解剖研究,系统观测腘窝中间皮动脉及其上行支的起始、走行、外径、分支、伴行静脉及供血范围。结果:腘窝中间皮动脉均起自腘动脉;起始点位于股骨内外髁连线中点上方(28.50±4.92)mm;起点外径(1.92±0.12)mm;上行支长度(250.03±9.24)mm;末端外径(0.33±0.09)mm;皮支(21±3)条;供血范围在股后区25cm×10cm。有两条伴行静脉,外径(1.41±0.1)mm。结论:腘窝中间皮动脉上行支起点、走行恒定,外径较粗,有较多皮支和恒定的供血范围,可设计以股后为供区的逆行岛状皮瓣。
Objectivo： To explore anatomic basis of the island flap pedicled with the popliteal intermediate cutaneous artery （PICA）. Methods： 10 fresh cadaveric specimens were microdissected. The origin, courses, diameter and length of PPICA and its branches are measured. The region they supplied and the relationship with the veins accompanied was determined. Results：All the PPICA of 10 specimens arose from the popliteal artery. The origin was （28.50±4.92） mm proximal to the middle point between the medial and lateral condyles of the femur. The diameter of the origin of PICA was （1.92±0.12） mm. The length and diameter of ending point of the ascending branch were （250.03±9.24） mm, and （0.33±0.09） mm respectively. There were （21 ±3） branches originated from the ascending branch. The scope of the flap was about 25 cm× 10 cm. Conclusions： The location and course of ascending branch of PPICA are constant with the wide diameter. For its extensive and constant blood supply and plenty of cutaneous branches, the flap is a better choice to repair soft tissue defect in the knee or upper calf.
