The arterial supply of the abdomen is unique for each individual. The conventional description and illustration of the

arterial blood supply to the intestinal tract are too incomplete which may mislead the surgeons in the intestinal surgery.

Surgical procedure for diseases of colon is one of the most common operative procedures performed by the surgeons.

The blood supply to the intestinal tract is mainly from the superior mesenteric artery (SMA) & inferior mesenteric artery (IMA), Branches from

abdominal aorta. Variations in anching pattern of arteries are common. These variations are usually due to the changes occurring during the

development of vessels. The knowledge of the anatomy of colonic mesenteric arteries & it�s distribution is necessary to accomplish successful

uncomplicated abdominal operations, especially laparoscopic colonic resections in which the mesenteric vessels cant be palpated. We studied

the pattern of distribution of the Inferior mesenteric artery (IMA) & it�s anches in formalin preserved 50 cadavers at the department of Anatomy,

MGM Medical College, Navi Mumbai, India. .This study was conducted to enlighten our knowledge about colonic blood supply.
