ABSTRACT

Background: the kidney arterial irrigation, as it is classically described, occurs from the renal artery and its two terminal branches exclusively. The aim of this research was to determine the presence and distribution of the polar arteries.
Method: a quantitative, longitudinal, prospective, observational and descriptive study was carried out on 37 tissue samples from dead bodies without aortic renal surgeries or congenital demonstrable reno-ureteral malformations at “Celia Sánchez Manduley” Teaching Provincial Clinical-Surgical Hospital of Manzanillo, Granma. The samples were washed, fixed and dissected through the direct macroscopic method.
Outcomes: The polar arteries were more frequent in the male sex and on the right side, being found in 16 cases (43.24%), 9 of which presented, at least, a superior polar artery; 3 presented at least an inferior polar artery; and 4 cases presented at least one of each type of polar artery. The origin of both polar arteries as a direct branch of the aorta was predominant.
Conclusions: The polar arteries are not anatomical variants of rare presence, and our knowledge of them is of vital importance in planning the removing and reconstructive nephro-urologic surgery.
