Combination of Aortic Stent-Graft and Arterial Embolization for Ruptured Bronchial Artery Aneurysm

Mediastinal bronchial artery aneurysm with short inflow segment successfully treated with a patent ductus arteriosus occluder device

“…Several previous reports have described the use of thoracic stent grafts to exclude proximal mediastinal BAAs that originate close to the thoracic aorta. 5,6 In a case described by Hu et al, 7 the sac of the proximal BAA was initially embolized with gelatin sponge before the deployment of a thoracic stent graft, resulting in occlusion of both the inflow and outflow of the aneurysm. Although thoracic stent grafts are useful in emergent situations, for example, in cases of acute rupture with active bleeding, their use can lead to complications such as endoleak.…”

Aortic Stent-Graft for a Giant Bronchial Artery Aneurysm with Ultrashort Neck

“…5,6) Various embolic materials have been used to treat bronchial artery aneurysms, such as, steel coils, gelatin particles, fibrin sealant, and PVA particles. [5][6][7][8] The advantage of using transcatheter BAE and an aortic stentgraft in combination, as opposed to transcatheter BAE only, is that it blocks blood flow into the aneurysm and prevents the development of potential collateral arteries arising from the thoracic aorta. 8) Up to now, six cases of bronchial aneurysm treated with aortic stent-graft have been reported in the English literature.…”

“…3,[5][6][7][8][9] Five of them were treated by transcatheter BAE plus aortic stent-graft placement. 3,[5][6][7][8] On the other hand, Kasashima, et al 9) used an aortic stent-graft only. They could not pass the catheter into the bronchial artery because the root of the bronchial artery was deviated and narrowed due to compression by the aneurysm.…”

Transcatheter embolization of a large mediastinal bronchial artery aneurysm with short neck

“…Advances in endovascular techniques have however led to a recent change in treatment planning. There are few case reports demonstrating successful embolization of mediastinal BAAs with short vascular necks . The treatment involved using coils, stent‐grafts or a combination of both.…”
