应用30例注入红色乳胶的新鲜成人下肢,研究了供应大腿内中部皮瓣的缝匠肌内缘中皮动脉。该动脉出现率为93.3%,并且全部来源于股动脉。其起点处平均外径为1.69±0.08mm。穿深筋膜后该动脉可分为升支、横支和降支。 Using 30 fresh adult limbs infused with red latex, the medial arteria sarcolei of the sartorius muscle, which supplies the mid-thigh flap, was studied. The incidence of this artery was 93.3%, and all from the femoral artery. The starting point of the average outer diameter of 1.69 ± 0.08mm. After the deep fascia, the artery can be divided into ascending branch, transverse branch and descending branch.
