A coarctation of the distal thoracic aorta with a supradiaphragmatic origin of the celiacomesenteric trunk: an anatomic and etiologic description.

Stenosis of the distal thoracic aorta was found during an evaluation for incidentally detected hypertension in a 21-year-old male patient. A celiacomesenteric trunk originated from just above the coarctation site in the thorax, and the lower posterior intercostal arteries showed unusual low origins. Consideration of these anatomies suggests that the etiology of this case is congenital.
