关于肾器官外肾动脉的研究,文献中已有许多记载。笔者在解剖一具成年男尸时,见其双侧肾都有肾器官外迷走动脉,现报道如下:左、右肾动脉各一条,于肠系膜上动脉起始部的稍下方,呈直角起自腹主动脉。左、右肾动脉的起点同高,但右肾动脉略粗于左肾动脉。右肾动脉从腹主动脉发出后,走行在下腔静脉的后方,右肾动脉的初级分支有七支,其中四支分别经肾下端的前唇(二支)、后唇(二支)穿入肾实质,另三支经肾门入肾。左肾动脉的初级分支有四支,其中二支经肾门入肾,另二支经肾下端的前唇穿入肾实质。左、右两侧肾迷走动脉,于肠系膜上动脉起始部的同高处,呈直角从腹主动脉左、右侧 There are many records in the literature about the study of the renal artery outside the kidney. The author in the dissection of an adult male corpse, see both kidneys have kidney organs outside the vagus artery, are reported as follows: the left and right renal artery of each one, at the beginning of the superior part of the superior mesenteric artery slightly below the right angle from the abdomen Aorta. Left and right renal artery with the same high starting point, but the right renal artery slightly thicker than the left renal artery. Right renal artery after the issue from the abdominal aorta, walking in the inferior vena cava rear, the primary renal artery has seven primary branches, four of which were the lower extremity of the anterior lip (two), the posterior lip (two) penetrate Renal parenchyma, the other three by the renal portal into the kidney. The left renal artery has four primary branches, of which two by the renal portal into the kidney, and the other two through the lower extremity of the anterior lip penetration into the renal parenchyma. Left and right renal vagal artery in the beginning of the superior mesenteric artery at the same height, at right angles from the abdominal aorta left and right
