ABSTRACT

Introduction: The inferior mesenteric vein drains blood from part of the large intestine and usually terminates in the splenic vein. It may drain into superior mesenteric vein or junction of superior mesenteric vein and splenic vein. Knowledge of such variations is very useful and important for anatomists, radiologists and surgeons performing surgeries related to this region.

Materials and Methods: The study was carried on 15 enblock specimens of duodenum, pancreas and spleen to understand the anatomy of drainage pattern of inferior mesenteric vein.

Results: It was found that in 11 specimens (73% cases) IMV drained into splenic vein at different sites. In 3 cases (20%) it drained at the junction of SMV& SV at level of formation of portal vein. In one case it was found that IMV drained nearly into SMV.

Conclusion: From the present study it was concluded that the inferior mesenteric vein does indeed drain into three  sites: the splenic vein, the superior mesenteric vein, or the junction between the superior mesenteric vein and the splenic vein. This study would be useful for the anatomists, surgeons and radiologists dealing with this region.

Key words: Inferior mesenteric vein, superior mesenteric vein, portal vein, splenic vein.
