When it comes to blood vessels, alterations in embryological development may lead to the duplicity and the agenesis of vessels, or cause the emergence of arteries and the disembogue of vessels not according to the standard anatomical description. Case report: Dual anatomical variation in an individual was observed during a routine dissection in the Laboratory of Anatomy of the Centro Universitário São Camilo. The main renal artery originated in the abdominal part of the aorta artery, following its path until its entry in the renal hilum. However, instead of a rectilinear path from the aorta, it had a descending and well-angulated path. From the main renal artery, an aberrant polar artery emerged, that entered the inferior pole of the right kidney. At a lower level, on the same level as the bifurcation of the aorta, another aberrant polar artery emerged, which entered the renal hilum following a straight path to the inferior pole of the right kidney. The common hepatic artery was originated in the celiac trunk, following its path until its entrance in the porta hepatis. The superior mesenteric artery was originated in the celiac trunk. The right hepatic artery was originated in the superior mesenteric artery. Conclusion: The study of anatomical variations is an arduous task due to the innumerable different expressions that occur in the human body. However, the knowledge of these variations is extremely valuable for medicine and surgical planning, assuring accuracy and avoiding postoperative complications or erroneous diagnoses.</p> ER -
