Abstract :Purpose: This cadaveric study aimed to identify the multiple renal arteries and evaluate their association with other anatomical abnormalities. The possible clinical consequences of more than one renal artery were analyzed. Material - methods: This study was carried out by accessing the Abdominal aorta (AA) of 20 American cadavers [12 males, 8 females, ages 50-96] donated to the C&DA Department of Albert Einstein College of Medicine. From the cadavers in the supine position, the branch points of the renal artery from the abdominal aorta on the right and left sides were checked to see if there was more than one. Renal artery (left side), celiac trunk, superior mesenteric artery, inferior mesenteric artery, and aortic bifurcation were measured in 3 ways: linear, longitudinal, and transverse. The obtained results were assessed using a comparative analysis with earlier research findings documented in the literature. Results: Among the 20 cadavers included in the study, two males, aged 62 and 80, were found to have two renal arteries on the right side, and both of them are hiler arteries. These multiple renal arteries were coexistent with splenomegaly, tortuosity of the abdominal aorta, and deviation of the vertebral column at the level of the 3rd lumbar vertebra. 94.7% of the cadavers exhibited normal renal arterial anatomy. The most common branching locations of the main renal arteries and multiple renal arteries (MRA) were found find from the abdominal aorta. Conclusion: Before surgical or radiological procedures in the anatomical region related to and adjacent to renal arteries, knowing the possible renal artery variations in the anatomy of the region is very important to reduce mortality and morbidity during surgical or interventional procedures. Knowing the anatomy of renal arteries and evaluating it radiologically will guide renal transplantation, hepatorenal surgery, interventional radiology, and nephrology the prevention and treatment of many conditions, such as hypertension, and target organ damage.
