Abstract

Objectives: Variations in branching of vessels have always been an area of keen interest in the field of anatomy. Variations of arteries are known and mentioned in literature too although studies on pattern of drainage of veins are lacking. With this interest the following study was done with its importance in abdominal organ mobilization resections surgeries. Materials and Methods: Present study was conducted with 24 formalin embalmed cadavers (20 Males and 4 Females) procured from department of anatomy, Dr. D. Y. Patil Medical College, Dr. D. Y. Patil Vidyapeeth Pimpri Pune, India. Results: Inferior mesenteric vein drains venous blood from superior part of rectum, sigmoid colon and descending colon and generally terminate into splenic vein. However it may drain into superior mesenteric vein, at the junction of superior mesenteric and splenic vein or portal vein. Conclusions: Knowledge of such variations of draining pattern of inferior mesenteric vein is an important prerequisite for surgeons to choose an adequate technique to avoid injury during colorectal surgeries especially at the time of inferior mesenteric vein ligation.
