Rogie’s Venous Quadrilateral: Anatomical Variants

Abstract

The Rogie’s venous quadrilateral is an anatomical region where the inferior mesenteric vein, splenic and superior mesenteric veins drain in the hepatic portal vein. The hepatic portal vein is a large caliber vessel that collects venous blood from the stomach, jejunum, ileum, duodenum, colon and part of the sigmoid. In the human macroscopic anatomy laboratory at Universidad Nacional Autónoma de Honduras en el Valle deSula (UNAH-VS) we found two anatomical variants the components of the Rogie’s venous quadrilateral in relation to the abdominal aorta and the way the inferior mesenteric vein drains. The first variant found was the inferior mesenteric vein draining directly into junction between the splenic and superior mesenteric veins. The second variant found was in the same region and body in the post inferior limit of the Rogie ́s venous quadrilateral, where the left renal vein runs posterior to the abdominal aorta. This retro aortic position of the left renal vein could be harmful in case the abdominal aorta compressing it.
