Mediastinal bronchial artery aneurysms: endovascular therapy in two patients.

We report two patients with cystic fibrosis and mediastinal bronchial artery aneurysms treated by means of endovascular coil embolization. In one case, the presence of a long segment of bronchial artery proximal to the aneurysm allowed coil embolization with regular steel coils. In the second case, the aneurysm was near the origin of the bronchial artery from the aorta. We used detachable coils to occlude this aneurysm for more precise embolization.
