睾丸动脉支数的变化,通常有左1右2(8.4%)和左2右1(4.5%),但鲜见左2右2的报道.作者在制作动脉标本时,在成年男性尸体上,见左、右侧睾丸动脉均有2支(左2右2),分别起自肾动脉、主动脉腹部、根据起始,将起自肾动脉的称为上睾丸动脉(变异的睾丸动脉);起自主动脉腹部的称为下睾丸动脉.1.上睾丸动脉 左上睾丸动脉起自左肾动脉干,外径1.0mm,在同名静脉的内侧于腰大肌前面下行、至第四腰椎高度,与下睾丸动脉一起、下行经腹股沟管至睾丸.右上睾丸动脉发自右肾动脉前干,外径1.2mm,在同名静脉的外侧、腰大肌前面下行至第五腰椎处,与同侧下睾丸动脉一起到达睾丸.2.下睾丸动脉左、右侧均在第三腰椎处,肠系膜下动脉下方12mm、主动脉腹部分叉处上方45mm处发自主动脉腹部的前外侧壁,左下睾丸动脉外径1.1mm,右下睾丸动脉外径1.0mm.同时,本例还发现左肾上端平第十二胸椎,下端至第三腰椎,位置低于右肾.左肾动脉在右肾动脉起点下方10mm处发自主动脉腹部的左壁.从动脉起始部位看,左肾位置低于右肾并非后天肾脏位置下移所致
Changes in the number of testicular artery branches, usually left 1 right 2 (8.4%) and left 2 right 1 (4.5%), but rarely seen on the left 2 right 2. The author in the production of arterial specimens in adult male bodies, See the left and right testicular arteries are 2 (left 2 right 2), respectively, from the renal artery, abdominal aorta, according to the beginning, from the renal artery called the upper testis artery (mutated testicular artery); From the abdominal artery of the lower called the lower testicular artery .1. The upper testicular artery from the left renal artery from the arterial artery, diameter 1.0mm, in the medial vein of the same name down in front of the psoas to the fourth lumbar spine height, and Under the testicular artery, the descending transbronchial tube to the testis. Upper right testicular artery from the anterior renal artery anterior, outer diameter 1.2mm, in the same name outside the vein, anterior psoas down to the fifth lumbar vertebra, and ipsilateral lower testis Arteries reach the testis .2. The lower left testis artery left and right in the third lumbar vertebra, the inferior mesenteric artery 12mm, aortic abdominal bifurcation 45mm above the anterior abdominal wall originated from the abdomen, the lower left testicular artery diameter 1.1mm, lower right testicular artery diameter 1.0mm.At the same time, this case also found that the upper left of the left kidney flat thirteen chest , The lower end of the third lumbar spine, lower than the right kidney.The left renal artery from the right renal artery 10mm below the starting point of the left abdominal wall.From the starting point of the artery, the left kidney position is lower than the right kidney is not the kidney position Down due
