title: Median arcuate ligament syndrome: Use of fractional flow reserve in documentation of chronic mesenteric ischemia.
abstract: Median arcuate ligament syndrome (MALS) is a rare clinical entity. This condition typically affects women between the ages of 20 and 40 years and causes symptoms of abdominal pain, primarily post-prandial, as well as nausea, vomiting and weight loss. MALS is considered a diagnosis of exclusion. Typically, mesenteric arterial duplex ultrasonography, computed tomography (CT), and magnetic resonance (MR) are highly suggestive, and conventional contrast angiography confirmatory. We explore the role of fractional flow reserve and intravascular ultrasound in the evaluation of MALS. In order to illustrate the utility of these tools, we present the case of a 47-year-old symptomatic woman who underwent angiography, complemented by assessment of fractional flow reserve and intravascular ultrasound. These data convincingly demonstrated the dynamic nature of the obstructive characteristic of MALS.
