1.在120具成尸观察了肾脏动脉的数目、起始高度、入肾状态、经肾门入肾的肾动脉初级分支类型以及肾副动脉与输尿管和下腔静脉的位置关系。2.肾脏动脉为一支型者占84.2±2.35%;二支型者占15.4±2.33%;三支型者占0.4±0.41%。两侧均为一支型者占73.4±4.03%,为常见型。动脉支数的多少无显著的侧别差异。3.两侧肾动脉起点的平均高度为第1、2腰椎间的椎间盘。两侧起点同高者占50.0±5.23%,右高者占34.1±5.05%,左高者占15.9±3.90%。4.在二支型中,被列为正常肾动脉的平均起点高度为第2,腰椎上1/3平面;肾副动脉多由肾动脉起点下方发起,起点范围在第1腰椎上缘与第5腰椎上缘之间,其中以起自第1腰椎平面以下者多见。5.肾动脉分支全部经肾朗入肾者占78.2±2.90%,发穿支入肾者占21.8±2.90%。根据入肾部位,穿支可分为五类,其中以穿入肾上端者最多见,占穿支总数的70.5±6.87%。6.在二支型中,肾动脉经肾门入肾者占75.0±7.21%,发穿支入肾者占25.0±7.21%;肾副动脉经肾门入肾者占66.7±7.85%,在其余例内,则主要以独立穿动脉形式穿入肾的上端或下端。7.绝大多数(占83.7±2.60%)肾动脉在肾门外分支,其初级支可分五型,其中以前后股型和上下股型最多见。8.援引本文材料对肾副动脉与输尿管及下腔静脉的位置关系的临床意义作了初步探讨。
1. Observe the number of 120 renal arteries, the initial height, into the kidney, the renal artery through the renal accessorial primary branches and the relationship between the renal artery and ureter and inferior vena cava position. 2. A type of renal artery accounted for 84.2 ± 2.35%; two branches accounted for 15.4 ± 2.33%; three branches accounted for 0.4 ± 0.41%. Both sides are a type accounted for 73.4 ± 4.03%, for the common type. The number of arterial branches without significant lateral differences. 3. On both sides of the average height of renal artery as the first 1,2 lumbar intervertebral disc. The highest starting point on both sides accounted for 50.0 ± 5.23%, the higher right accounted for 34.1 ± 5.05%, the left higher accounted for 15.9 ± 3.90%. In the two branches, was listed as the average starting height of the normal renal artery 2, 1/3 plane lumbar; renal accessory arteries mostly from the start below the start of the renal artery, the starting point in the first lumbar margin and the 5 between the upper edge of the lumbar spine, which from the first lumbar plane following more common. Nephropathy renal branches into the kidney all accounted for 78.2 ± 2.90%, sent through the branch of kidney accounted for 21.8 ± 2.90%. According to the kidney into the site, perforation can be divided into five categories, of which the most common penetration of the upper kidney, accounting for 70.5 ± 6.87% of the total number of perforating branches. In the two branches, the diameter of the renal artery was 75.0 ± 7.21% in the kidney and 25.0 ± 7.21% of the patients in the kidney and 66.7 ± 7.85% in the kidney, In the remaining cases, the upper or lower end of the kidney is penetrated mainly in the form of an independent artery. 7. The vast majority (83.7 ± 2.60%) of the renal artery in the renal branch of the branch, the primary branch can be divided into five types, of which before and after the shares and the upper and lower strands are the most common. 8. Cite this article on the clinical significance of the relationship between the position of the renal secondary artery and the ureter and inferior vena cava made a preliminary study.
