Abstract
Background: Renal vascularization is classically described as a renal artery and vein. However, this vascular pattern presents numerous anatomical variations in terms of their number, origin and course due to ontogenetic alterations. The aim was to carry out a descriptive study of the renal vascular pattern observed during the dissection of cadavers intended for teaching purposes.
Materials and methods: A descriptive and observational study of renal vascular anatomy was carried out by dissecting 16 renal blocks from 8 cadavers donated to science and used for teaching at the Faculty of Medicine of the University of
Zaragoza.
Results: The prevalence of arterial variations was 75% (56.3% for polar renal arteries, 12.5% for pre-hilar branching and 6.25% for double communicating arterial arch) and venous was 62.5% (12.5% for polar renal veins, 25% for late venous confluence, 6.25% for triple renal vein and 18.75% for double circumaortic renal vein).
Conclusions: We conclude that the renal vascular anomalies occur with high frequency; for this reason, knowledge of these anomalies is extremely important for the correct planning of numerous medical-surgical activities.
