MDCT Evaluation of Celiac Axis Compression Syndrome- A Rare Case Series

Abstract

Celiac axis compression syndrome is an uncommon entity of abdominal vascular compression syndrome which results from the compression of the proximal celiac artery by the hypertrophied median arcuate ligament. The patients present clinically with postprandial abdominal pain predominantly in the epigastric region and weight loss. The use of thin-section Multidetector Computed Tomography (MDCT) and 3-Dimensional (3D) image reconstruction has greatly improved the ability to obtain detailed images and helped to assess the abdominal vascular system non invasively. Five cases of celiac axis compression syndrome with its characteristic MDCT imaging features like hooked appearance, thickened median arcuate ligament more than 4 mm, poststenotic dilatation and posterior and inferior displacement of celiac artery with indentation on aorta have been described in the present case series and the imaging findings described by other authors in their reported studies have also been compared.
