    Abstract:
    OBJECTIVE: Coarctation of the descending thoracic aorta is uncommon, with controversial etiology. Usually, severe hypertension is the main symptom; lower extremity claudication is less often found. Surgical management remains the standard for long coarctation and provides good results. METHODS: We report three cases of coarctation 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. Hypertension 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 aortic coarctation 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 hypertension. Depending on technical considerations, open surgical bypass remains the standard repair for mid-aortic syndrome.
