教科书和不少文献提及的旋髂浅动脉只有一支,即浅主支,忽略了还具有一条恒定的深主支。本文共观察50例标本,由旋髂浅动脉干分为浅、深两主支的占56％。浅主支的出现率为86％,发出后迅速穿深筋膜进入浅层,穿出点多在以股动脉起点外侧15毫米、向下10毫米处为中心的附近。浅主支的行程以股动脉起点下15毫米处与髂前上棘的连线为轴线,末支多转入腹外侧部。浅主支主要分布于腹股沟外侧半的两侧。深主支恒有,其行程以腹股沟韧带下15毫米处一条与韧带平行的线为轴线,末支多转入臀部,主要分布股外侧部上份和臀部。深主支穿深筋膜处,多在髂前上棘之下20毫米处的附近。旋髂浅动脉两主支起始处的管径各与其分布的范围大小密切相关。旋髂浅静脉的走向和旋髂浅动脉的一个主支相似,或在两主支之间(70％)。讨论了采用有关皮瓣的轴、厚薄和范围等问题。
Textbooks and many literatures refer to the iliac artery only one branch, that is, the main shallow branch, ignoring also has a constant deep main branch. In this paper, a total of 50 specimens were observed, which were divided into shallow and deep branches by 56% of superficial iliac artery. The prevalence of the main superficial branch was 86%. After it was delivered, the deep fascia was rapidly penetrated into the superficial layer. The piercing points were mostly located 15 mm outside and 10 mm below the origin of the femoral artery. The main branch of the trip to the starting point of femoral artery 15 mm anterior superior iliac spine and the connection as the axis, the end of multi-branch into the lateral part of the ventral. The main superficial branch is mainly located on both sides of the lateral half of the groin. The main branch has a deep, its trip to the inguinal ligament 15 mm at a parallel with the ligaments as the axis, the end of multi-turn into the buttocks, the main distribution of the outer part of the shares and buttocks. Deep main deep fascia, mostly in the vicinity of the anterior superior iliac spine 20 mm. The diameter of the main branch of the two branches of superficial iliac artery is closely related to the size of its distribution. Circumflex iliac vein to the iliac artery iliac artery and the main branch of a similar, or between the two main branches (70%). Discusses the issues of using the shaft, thickness, and extent of the flaps.
