教科书和不少文献对腹壁浅动脉的描述都没有分为两主支,动脉的行程和分布仅相当于本文所述内侧主支的范围,忽略了还具有一条与内侧主支相当的外侧主支。本文观察的50例标本中,腹壁浅动脉干分为内、外侧两主支的占20％。外侧主支的出现率为66％,穿阔筋膜进入浅层,穿出点多在以股动脉起点内侧5mm,向下15mm处为中心的附近。外侧主支的行程,以股动脉起点沿韧带向外侧10mm处的垂直线为轴线向上行,主要分布本侧下腹部中份偏外侧。内侧主支的出现率为68％,多穿卵圆窝进入浅层,穿出点多在以股功脉起点向下25mm处为中心的附近。内侧主支的行程以股动脉起点沿韧带向内侧10mm处的垂直线为轴线向上行,主要分布于本侧下腹部内侧半。两主支起始处的管径各与其分布范围的大小密切相关。讨论了以腹壁浅动脉或其主支为游离皮瓣血管源的轴线、厚度和范围等问题。
Textbooks and many of the literature on the description of the superficial abdominal artery are not divided into two main branches, arterial stroke and distribution is only equivalent to the scope of the main branch of the medial described in this article, ignoring the side of the main branch also has a lateral main branch . In this paper, 50 cases of specimens, the superficialis of the superficialis artery is divided into the medial and lateral two main branches accounted for 20%. The incidence of the lateral main branch was 66%, through the fascia lata into the superficial layer, out of the point in the medial femoral artery starting 5mm, down 15mm at the center of the vicinity. Outside the main branch of the stroke to the starting point of the femoral artery along the vertical line of the ligament to the outside 10mm as the axis upward, mainly in the lateral side of the lower abdomen in the partial lateral. The incidence of the medial main branch was 68%, and more to wear oval nest into the shallow, piercing point and more in the beginning of the femoral vein 25mm at the center as the center. The medial main branch of the stroke to the starting point of the femoral artery along the vertical to the medial 10mm at the line as the axis upward, mainly in the medial half of the lower abdomen. The diameter of the two main branches at the beginning of each with the size of its distribution is closely related. The axis, thickness and extent of the vascular source with the superficial abdominal artery or its main branch as free flap were discussed.
