Anatomic variations of the hepatic arterial irrigation in a Mexican population: contrast enhanced computer tomography evaluation: a cross-sectional study

Background: Knowledge and mastery of the anatomical variability hepatic arteries are essential for surgical disciplines and, given their complexity importance over time, they have been extensively studied described.Methods: A retrospective, cross-sectional, analytical study was carried out in which contrast-enhanced computer tomography (CT) studies between January 2021 December at North Central PEMEX hospital were analyzed. total 207 CT scans analyzed, Statistical analysis performed with statistical software IBM® SPSS© Statistics.Results: Uflacker type I found 90.8%, Michel class arterial irrigation 70.5%, origin CA documented right (RHA) 90.3%. Multiple cystic artery (Cas) identified 1% Moynihan's hump 0.5%. The mean length common (CHA) 53 millimeters.Conclusions: tomographic variants is an accessible non-invasive tool. nomenclature described present work allows a precise straightforward understanding clinical-surgical utility.
