Cadaveric incidence of renal artery variations at SRTR Govt. Medical College Ambajogai

Abstract

Introduction: Vascular anomalies related to the renal arteries are not uncommon. The literature indicates that multiple renal arteries are found in 9-76% of cadavers. Two groups of renal artery variations are considered, the early division (ED) and extra renal arteries (ERA). Surgeons operating on the kidney must be acquainted with normal and abnormal anatomy of the renal vessels to avoid inadvertent injury. Aim of this study was to establish the prevalence of cadaveric renal artery variations with the Objective to bring awareness to the surgeons and radiologists performing vascular surgeries and invasive procedures respectively. Materials and Methods: This is a descriptive observational study wherein dissected cadavers were observed for the presence of renal arterial variations. The study was conducted in the department of anatomy, SRTRGMC, Ambajogai, Maharashtra over a period of 2012-2017 and total of 30 cadavers that is total 60 kidneys were observed for the presence of various renal arterial variations during routine abdominal dissection conducted for medical undergraduates. Result: In this present study the incidence of various renal artery variations taken together amongst all cadaveric kidneys observed was 36.66%. Incidence of ERA was 20% and Incidence of ED was 16.66%. Keywords: Renal artery variations, Extra renal artery, Early division, Ladder pattern, Fork pattern.
