Abstract
Median arcuate ligament syndrome, a rarely reported condition, is characterized by postprandial abdominal pain, nausea, vomiting, and weight loss. Its cause is unclear. We present the case of a 45-year-old woman who had intermittent chronic positional abdominal pain without weight loss. Magnetic resonance angiograms and computed tomograms revealed stenosis of the celiac artery. Ostial compression was confirmed on catheter angiographic and intravascular ultrasonographic images. Intravascular ultrasound revealed far greater stenosis than did the initial imaging methods and confirmed a diagnosis of median arcuate ligament syndrome. In lieu of surgery, the patient underwent a celiac ganglion block procedure that substantially relieved her symptoms. To our knowledge, this is the first report of the use of intravascular ultrasound in the diagnosis of median arcuate ligament syndrome. We recommend using this imaging method preoperatively in other suspected cases of the syndrome, to better identify patients who might benefit from corrective surgery.
