Context: The anatomy and variations of abdominal aortic branches needs to be established at pre operative imaging to avoid/ minimize the ischemic complications that could occur during surgeries such as liver transplants, laparoscopic surgery, vascular interventions etc. Aims: To determine the comprehensive spectrum of celiac axis, hepatic and renal artery variations with the use of multi-detector computed tomography (MDCT). Methods and Material: CT images of 200 patients who underwent MDCT abdomen in our hospital for various indications between June to September 2013 were analyzed retrospectively. The celiac trunk, hepatic and renal arterial system were individually assessed and variations noted. Statistical analysis used: The possibility of an association between celiac-hepatic arterial variations and renal artery variations were assessed using chi-square test with p < 0.05 as statistically significant. Results: There was normal trifurcation of celiac trunk in 95% patients, hepatosplenic trunk and gastrosplenic trunk (celiac bifurcation) in 2.5%, and quadfurcation in 1%. Hepatic artery variations were present in 67 patients (33.5%) and renal artery variations in 76 patients (38%). Celiac trunk and/ or hepatic artery variations were present in 38 of 124 patients (30.6%) with no renal artery variation and in 36 of 76 patients (47.3%) with renal artery variations. There was a statistically significant correlation noted between renal artery variations and coeliac trunk–hepatic arterial system variations (p= 0.026 by chi square test). Conclusions: Variations in the celiac trunk, hepatic artery and renal artery are common and their detection is important prior to any interventions or abdominal surgeries. MDCT allows rapid, accurate non-invasive evaluation of these variations.
