1.采用剥离、塑型和动脉造影方法研究了130例成人和儿量肾动脉在肾内的吻合、分支和分布。2.肾动脉在肾内呈节段性分布。分段动脉造影、动脉塑型和不同颜色赛璐珞分段塑型都表明,肾段动脉间无吻合,按照分支,在多数例内可把肾分为顶、上、中、下和后段。3.一支型肾动脉通常在肾门外分成前后干和上下干。前干往往分成顶、上、中、下段动脉,布于肾前部和后方小部,后干为后段动脉,布于肾后部中央区域;上千通常分成顶、上、中、后段动脉,下干为下段动脉,或上干分成顶、上、后段动脉,下干分成中、下段动脉。顶、下段动脉的数目、起源和分布范围常有变化。4.两支型肾动脉仍按节段性分布,其中一支作为下段或顶段动脉,另一支分成其余段动脉者多见,共占70.58±11.05%。三支型肾动脉也呈节段性分布。5.肾动脉初级干在肾内的分支形式以肾前部为分散型,后部为主干型多见。这种分支形式与肾外形及肾唇形状密切相关。6.肾段动脉在肾门处的位置具有一定规律性,本文分为三类,熟悉这种位置可迅速确定各肾段动脉。
1. Peel off, modeling and arteriography were used to study the anastomosis, branching and distribution of 130 adult and pediatric renal arteries in the kidney. 2. Renal artery was segmental distribution in the kidney. Segmented arterial angiography, arterial modeling, and celluloid segmental modeling of different colors all showed no anastomosis between the renal arteries and, in most cases, the kidneys were divided into the top, upper, middle, lower and posterior segments according to the branch. 3. A renal artery is usually divided into before and after the renal hilar and dry up and down. Dry before is often divided into top, upper, middle and lower arteries, cloth in the anterior and posterior small renal artery, the posterior segment of the artery, located in the central area of the back of the kidney; thousands are usually divided into top, upper, middle and rear Artery, under the dry artery for the next paragraph, or on the dry into the top, on the posterior segment of the artery, the next dry into the lower artery. The number of arterial top and bottom, the origin and distribution of the often change. 4. The two renal arteries were still segmental distribution, one of them as the lower or top artery, and the other one was divided into the remaining segments more common, accounting for 70.58 ± 11.05%. Three renal artery also showed segmental distribution. 5. Primary renal artery in the kidney branch of the kidney in front of the form of dispersion for the back of the trunk more common. This branch form and kidney shape and shape of the kidney are closely related. 6. The renal arteries in the renal door at a certain degree of regularity, this article is divided into three categories, familiar with this location can quickly determine the renal arteries.
