[Middle XXXX : A rare vascular disorder.]

@entity2333 @entity1498 @entity613 @entity101
OBJECTIVE: Coarctation of the descending thoracic aorta is uncommon, with controversial etiology. Usually, severe @entity101 is the main symptom; lower @entity613 is less often found. Surgical management remains the standard for long @entity1498 and provides good results. METHODS: We  report three cases of @entity1498 of the descending aorta operated at our department of cardiovascular surgery of Hospital La Rabta between January 2012  and December 2013. RESULTS: The median age was 19  years and the median follow-up was 16  months. @entity101 was the most common clinical manifestation. The diagnosis was made by computed tomography angiography. Two cases were treated by an aorto-aortic bypass and one by subclavian-descending aorta bypass. Recovery was excellent, with a decrease in antihypertensive medications (four to two) and restoration of all distal pulses. CONCLUSIONS: Middle @entity1498 is a rare entity. Etiologies include congenital, acquired, inflammatory and infectious causes. The condition is considered a life-threatening emergency as a result of the complications associated with severe @entity101 . Depending on technical considerations, open surgical bypass remains the standard repair for @entity2333 .
