Anévrisme médiastinal de l'artère bronchique : traitement par endoprothèse aortique

Mediastinal bronchial artery aneurysm is rare but potentially life-threatening, and requires prompt treatment to avert rupture with catastrophic results. Inflammatory conditions dominate the aetiologies. Conventional therapies are surgery via thoracotomy and endovascular embolization. We report a case of a giant saccular aneurysm of the bronchial artery described in an 80-year-old man, adjacent to the descending aorta, simulating aortic aneurysm and causing esophageal compression. It was totally excluded with an aortic stent-graft (TX2, Cook) performed through femoral access. Our case is the fourth reported of mediastinal bronchial aneurysm stent-graft exclusion. The analysis of success, complications rate and hospital stay duration favors endovascular grafting comparing with conventional techniques.
