Is celiac artery compression syndrome genetically inherited?: a case series from a family and review of the literature.

The median arcuate ligament is a tendinous arch joining the two medial borders of the diaphragm crura together. In 13-50% of asymptomatic subjects it is responsible for significant angiographic celiac trunk compression. The significance of median arcuate ligament-associated celiac artery compression has been a source of some controversy in the past literature, and the etiology remains unclear. We report here a case series from a family that was diagnosed by the use of multidetector computed tomography. The observation of this syndrome in a family suggests that the responsible anatomic relationships are congenital and may be genetically inherited.
