Anatomical Variation of Celiac Axis Artery in Karaikal Population: MDCT Angiographic Findings

Journal Title: International Journal of Anatomy Radiology and Surgery - Year 2019, Vol 8, Issue 1

Abstract

ABSTRACT Introduction: The first branch of the abdominal aorta, the celiac axis is the main arterial supply to the foregut structures. Anatomical variations in such important arteries are very important for the surgeons and interventional radiologists. Conventional angiography has been replaced nowadays by the CT angiography to guide the surgeons and prevent complications such as injury to these arterial branches. Aim: To find the prevalence of variations in the anatomy of the celiac trunk in the population of Karaikal, Pondicherry using Multidetector CT (MDCT). Materials and Methods: A prospective study was conducted in which total of 300 consecutive patients from 20-60 years of age referred for a contrast enhanced CT study of the abdomen were included in the study. The arterial phase sequence is used for the evaluation of the celiac trunk and its branching pattern. The images were reported by two separate radiologists who were blinded to the report of the other. Kappa correlation test was used to analyse the data obtained. Results: The classic celiac axis anatomy was noted in 222 (74%) patients. The most common variant identified was the origin of left hepatic artery from left gastric artery which was seen in 26 patients. The second most common variant which is the direct origin of left gastric artery from abdominal aorta was seen in 20 patients. Other variants identified were Accessory splenic artery from the left gastric artery, Common trunk of celiac artery and superior mesenteric artery, Left hepatic artery originating from the celiac artery and the left gastric artery from the splenic artery and direct origin of left hepatic artery off the celiac axis. A rare variant of left gastric artery from the splenic artery was identified in one patient. The agreement between the two radiologists who separately reported the images was found to be 0.84. Conclusion: Out of the 300 patients, 78 patients (26%) had variant anatomy of the celiac axis which is one-fourth of the total number of patients in the study. Most common variant identified is the origin of left hepatic artery from left gastric artery in 26 patients while direct origin of left gastric artery from abdominal aorta being the second commonest variant identified in this study in 20 out of the 78 patients with variant anatomy.
