Variations in the origin of arteries in the abdomen are very common but with the invention of new operative techniques within the abdominal cavity, the anatomy of abdominal vessels has assumed much more clinical importance. During routine dissection of the abdominal cavity, we came across multiple arterial anomalies involving testicular and suprarenal arteries. On the right side, there was double testicular artery (medial and lateral) and the right inferior suprarenal artery aroused from the medial testicular artery. The right inferior phrenic artery (IPA) and middle suprarenal artery took origin from a common trunk just above the origin of right renal artery (RRA). On the left side, the left testicular artery was arching over the lower tributary of the left renal vein proper (LRVP). Apart from the developmental and morphological interest in arching gonadal arteries, they are of practical importance from a clinical and surgical viewpoint. The embryological and clinical significance of above variations has been described.
腹部动脉起源的变异非常常见,但随着腹腔内新手术技术的发明,腹部血管的解剖结构在临床上具有了更为重要的意义。在腹腔常规解剖过程中,我们发现了多例涉及睾丸动脉和肾上腺动脉的动脉异常情况。右侧有双睾丸动脉(内侧和外侧),右肾上腺下动脉起自内侧睾丸动脉。右膈下动脉(IPA)和肾上腺中动脉共同起自右肾动脉(RRA)起始部上方的一个共同干。左侧,左睾丸动脉在左肾静脉固有支(LRVP)的下支上方呈弓形走行。除了弓形走行的性腺动脉在发育和形态学上的研究价值外,从临床和外科角度来看,它们也具有实际重要性。上述变异的胚胎学和临床意义已作描述。
