The purpose of this project is to report the variable drainage pattern of the inferior mesenteric vein (IMV) as reported by medical students’ observations recorded on anatomical variation data sheets (n = 192). A meta-analysis on the drainage pattern of the inferior mesenteric vein as described in various anatomy resources was conducted (n = 40). The inferior mesenteric vein was observed to drain into the splenic vein, the superior mesenteric vein, and the junction between the superior mesenteric vein and the splenic vein. Anatomy resources do not commonly report all three drainage sites. It is imperative that all these common drainage sites of the inferior mesenteric vein are stated in anatomy resources, so that students are taught realistic human anatomy including its common variations.
