Extra coeliac axis origin of cystic artery: a cadaveric study

Abstract

Abstract Background: A thorough knowledge of extra hepatic biliary system vasculature is very important for surgeons to avoid iatrogenic bleeding during upper abdominal surgeries. Aim: Cystic artery usually a branch of right hepatic artery rarely has anomalous origin from coeliac trunk or from its branches. Very rarely it has an extracoeliac origin. The aim is to study the incidence of origin of cystic artery other than coeliac trunk. Material and method: The study was done on 50 formalin fixed cadavers [32male, 18 female] in the department of anatomy, Bangalore medical college and research institute during 2014-17. During routine dissection of coeliac trunk, cystic artery was traced and observed for its origin. Results: Cystic artery took its origin from right hepatic artery in 37 [74%], left hepatic artery in 9[18%], hepatic artery in 3[6%] and superior mesenteric artery ini [2%] cadaver. Conclusion: The incidence of extra coeliac axis origin of cystic artery is 2% which arose from superior mesenteric artery. Prior knowledge of these variations is important for surgeons and interventional radiologists during pancreatobiliary surgeries, angiogram and arterial embolization.
