摘要
观察５３具成人尸体腹主动脉主要的脏支及其分支：腹部干均为单支，４６例起于Ｔ１２高度，全发自主动脉前壁，９０％相当于１２点钟位，４７例腹腔干为典型的三主支型，变异的仅６例；肠系膜上动脉均为１支，其中３６例起于Ｌ１高度，全起自主动脉前壁，行向右前下，分支变异很少；肠系膜下动脉亦为单支，４４例在Ｌ３高度发自主动脉前壁，全部行向左下，分支极少变异；左、右肾动脉分别起于主动脉左右侧壁，全部位于Ｌ１￣２高度，
This paper offers an observation on the main visceral boughs of abdominal aorta andtheir branches in 53 cases of adult corpses. Everyone has a single celiac a tery,arising from the anteriorwall of the aorta (100%), at the point of 12 o'clock (90%), and at the level of the 12th thoracicvertibra (46/53). Among 53 cases, 47 have typical theree-branched celiac artery, while 6 show variationin branching. The superior mesenteric artery in these cases is one in number, all arise from theanteri or wall of the aorta, at the level of the 1st lumbra vertebra (in 36 cases). They pass downwards toanterior-right, having little variation in branching. The inferior mesenteric artery is also single in eachcase. They arise in 44 cases from the anterior wall of the aorta, at the level of the 3rd lumbra vertebra.They all goes downwards to the left, showing almost on variation in branching. The renal arteries arisefrom the right and left side of the aortic wall, respectively, at the level of the 1st to 2nd lumbravertebra. At the origin it goes at an angle of near 90°with the aorta, then passes in the exterior directinonand enter the kidney left renal arteries in 50 cases, and right in 49 cases, are of single branch whilethose in the rest are of two branches. Accessory renal artery is found in 33% of them, arising fronaorta or renal artery. Arteriae suprarenalis media are found in 50 cases of right and 51 cases of left, onebranch each and 95 branches arise from aorta.
