Background. Classically, each kidney is supplied by a single renal artery originating from abdominal aorta. The present study aimed at its variations and their embryological and clinical correlation. Material and Methods. The formalin-fixed thirty-seven cadavers from north India constituted the material for the study. During routine abdominal dissection conducted for medical undergraduates at the department of anatomy, the kidneys along with their arteries were explored and the morphological variations of renal arteries were noted. Results. We observed supernumerary renal arteries in 23/37 (62.2%) cases (48.6% of aortic origin and 13.5% of renal origin) on the right side and 21/37 (56.8%) cases (45.9% of aortic origin and 10.8% of renal origin) on the left side. Supernumerary renal arteries entered the kidney through hilum, superior pole, and inferior pole. Conclusion. Awareness of variations of renal artery is necessary for surgical management during renal transplantation, repair of abdominal aorta aneurysm, and urological procedures and for angiographic interventions.
背景。传统上,每个肾脏由一条发自腹主动脉的单一肾动脉供血。本研究旨在探讨其变异情况及其胚胎学和临床相关性。材料与方法。来自印度北部的37具福尔马林固定尸体构成了本研究的材料。在解剖学系为医学本科生进行的常规腹部解剖过程中,对肾脏及其动脉进行了探查,并记录了肾动脉的形态变异。结果。我们观察到右侧23/37例(62.2%)(48.6%起自主动脉,13.5%起自肾脏)和左侧21/37例(56.8%)(45.9%起自主动脉,10.8%起自肾脏)存在额外肾动脉。额外肾动脉通过肾门、上极和下极进入肾脏。结论。了解肾动脉变异对于肾移植、腹主动脉瘤修复、泌尿外科手术及血管造影介入治疗期间的手术管理很有必要。
