Mediastinal bronchial artery aneurysms: Endovascular therapy in two patients

Abstract

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.

Noninvasive diagnosis of bronchial artery aneurysm using dual-source computed tomography angiography

“…Up until the last decade, bronchial artery aneurysms have been treated surgically. Now, endovascular techniques such as transcatheter embolization are increasingly used and are shown to be effective in controlling bleeding (10,11). Provided the patient is stable, the first-line treatment should be radiologically guided coil embolization.…”

Percutaneous Embolization for Ruptured Ectopic Bronchial Artery Aneurysm

“…These permanent embolic agents can be positioned at the target site with fewer complications than other agents. 18 , 19 In our case, we reported a catheterization of the efferent branch was impossible because of the tortuosity of the ectopic right bronchial artery. Coils could not be deployed in the efferent branch, so PVA particles were chosen to embolize both the afferent and efferent vessels, including the aneurysm itself.…”

“…Among these, coils are most commonly used to treat BAA. They can be positioned at the target site with fewer complications than other agents [13] , [14] . To prevent retrograde filling of the aneurysm, both the afferent and the efferent of BAA need to be occluded [15] .…”
