Abstract

The surgical procedures on the caecum demand a precise knowledge of vascular anatomy of ileocolic region. The aim of this study is to study the arterial supply of the caecum, findings of which may reveal more anatomical facts about the arteries of caecum and their variations. Total 52 specimens of caecum and appendix with their arteries intact were collected, cleaned and dissected. The ileocolic artery and its branches to the caecum, and ileum were traced carefully and observations were recorded. The ileocolic artery arises independently from superior mesenteric artery in 96.88% of cases and ends by dividing into superior and inferior division in 93.76% of cases. The anterior and posterior caecal arteries arise by a common trunk in 56.25%. The ileocolic artery arises from the superior mesenteric artery independently in 96.88% and terminates into superior and inferior division in 93.76% of cases. Common caecal artery seen in 56.25% of cases, arises from inferior division (43.75%), superior division (9.38%) and ileocolic artery (3.12%).Anterior caecal artery arises from superior division (12.5%), inferior division (15.63%), ileocolic artery (3.12%), ileal branch (6.25%) and arterial arcade (6.25%).The posterior caecal artery arises from superior division (18.76%), inferior division (9.38%), ileal branch (3.12%), ileocolic artery (3.12%), arterial arcade (6.25%) and from ascending colic branch of inferior division (3.12%). 21.87% of cases showed additional anterior and posterior caecal arteries.
