Clinical and multidetector computed tomography findings of patients with median arcuate ligament syndrome.

OBJECTIVES

The present study aimed to present the clinical and multidetector computed tomography (MDCT) findings of patients who were diagnosed with the median arcuate ligament (MAL) syndrome on MDCT retrospectively.

METHODS

Seven hundred forty-four patients in whom MDCT angiography was performed were retrospectively analyzed for investigating incidental MAL syndrome.

RESULTS

Twenty-one patients were shown to have MAL syndrome. Of 21 patients, 18 with MAL syndrome were asymptomatic. Three patients had some symptoms. On MDCT angiography, proximal narrowing of the arteries was observed in 21 patients.

CONCLUSIONS

MDCT is a minimally invasive and useful tool for the diagnosis of MAL syndrome.
