The abdominal aorta predominantly provides blood supply to the upper abdominal cavity and its contents. Its major branches include the celiac trunk, superior mesenteric artery, and inferior mesenteric artery. Abdominal aortic branch variants are relatively prevalent and can impact certain surgeries. During embryonic development, the 10th to 13th vitelline arteries (Primitive intestinal arteries) communicate between the aorta and a primitive ventral anastomotic artery. Typically the ventral anastomosis and the 11th and 12th vitelline arteries regress, while the 10th and 13th roots give origin to the celiac trunk and the SMA, respectively.The remaining segments regress before birth. If the 10th to 12th vitelline arteries regress but there is abnormal persistence of ventral anastomosis, a celiacomesenteric trunk occurs. The study aims to estimate the prevalence of abdominal aortic branch variants in our study population by analyzing CT angiogram images. The CTA is considered the modality of choice for the evaluation of arterial anatomy, with a diagnostic accuracy of 97%-98% for detection of arterial variations. The study was conducted in Department of Radiodiagnosis, Kanyakumari Government Medical College & Hospital, Asaripallam, during the period of September 2021-August 2022. All the abdominal CT Angiogram done during this period was included in the study except cases with motion artifacts and inadequate contrast opacification.CT images were analyzed by an independent Radiologist using axial source images and post processing techniques like maximum intensity projection and volume reconstruction images. Variants of abdominal aortic branches was seen in 93 patients (38.75%) of study population. Additional renal hilar artery was the commonest variant (8.12%), the next common was the early branching of renal artery (7.91%). The incidence of the variant in celiac trunk was (3.3%). The commonest celiac trunk variant was celiac mesenteric trunk (1.66%) and splenohepatic trunk (1.66%).Radiologists have to be familiar with these variants and report these variants whenever possible in order to guide the operating surgeon/interventionist for planning management and reducing the inadvert complications.
