1.本文分析了140例国人肾器官外动脉、器官内动脉及肾外形与器官外、内动脉的关系。2.肾动脉的条数无论左侧或右侧都以一条的为多占85.71%。二条以上的占14.29%。肾动脉的一级分支以2支者为多占83.33%。2支的数目为3及4支相加总数的5倍。一级分支的起点,以在距肾动脉中点远侧的“近肾门型”为多占60%;在肾动脉中点近侧分的“近主动脉型”占16%;在肾窦内者占24%。3.肾内动脉的分支情况、类型常随肾动脉数及一级分支类型而异。平常所称不经肾门入肾的“肾副动脉”它们在肾内分布情况多数是正常的肾段动脉,所不同的只是起点及入肾门点的变化而已,我们认为与其叫做肾副动脉不如叫做“迷走动脉”比较恰当,因为迷走动脉只是表示其走行的不正常,并不说明其对于肾的一个区域的血液供给是处于主要或次要地位。4.肾外形与肾内动脉的排列形式有一定规律性的联系。肾前半有80%属于“蚕豆型”肾,肾后半有85%是“逗点型”肾。“蚕豆型”肾的肾唇95.38%是“齿状唇”它的段动脉排列有95.38%为分散的“复支型”。“逗点型”肾的肾唇有95.71%是“角状唇”,它的段动脉排列有97.85%是较集中的“主支型”。借助肾外形及肾唇形状,大致可以判断出来肾内动脉的分布规律,对于手术有指示意义。
1. This article analyzes the 140 cases of external organs of the renal artery, internal organ and kidney shape and organ, internal artery. 2. The number of renal artery regardless of the left or right to one of the more accounted for 85.71%. Two or more accounted for 14.29%. The first branch of renal artery to two branches accounted for more than 83.33%. The number of 2 branches is 5 times the sum of 3 and 4 branches. The origin of the primary branches was 60% more for the “nephrenoid” distal to the midpoint of the renal artery; 16% for the “proximal aorta” proximal to the midpoint of the renal artery; Inside accounted for 24%. 3. Branch of the renal artery, the type often with the number of renal artery and a branch type varies. Commonly referred to without renal portal into the kidney, “the secondary arteries,” their distribution in the kidney most of the normal renal artery, the only difference is the starting point and change into the point of the kidney, we think it is called the renal artery It is better to call the “vagus artery” because the vagus artery merely indicates that it is not moving properly, and does not indicate that its blood supply to a region of the kidney is in a primary or secondary position. 4. Renal shape and renal artery arranged in the form of a certain regularity. 80% of the first half of the kidney belongs to the “broad bean type” kidney, and 85% of the latter half of the kidney are “comma type” kidney. “Broad bean” kidney of the kidney lip 95.38% is a “toothed lip” its segment arteries arranged 95.38% for the scattered “complex type.” There are 95.71% of the kidney lip of the comma-shaped kidney, which is “horn-shaped lip”, and 97.85% of its segmental arteries are more concentrated “main branches.” With the kidney shape and shape of the kidney lip, can roughly determine the distribution of renal artery, which indicates the meaning of surgery.
