Background: Mediastinal bronchial artery aneurysms are uncommon, with fewer than 40 published case reports. This study objective was to evaluate the short term follow up of two cases ruptured Bronchial Artery Aneurysm (rBAA) treated with aneurysm embolization and subsequent aortic stent graft.
Methods: Two cases of rBAA were treated with a combination of an aortic stent-graft and aneurysm embolization. With rBAA, aneurysm embolization could be performed with sodium polymannuronate until the aneurysm was almost completely packed. One of the limitations of aneurysm embolization is spontaneous recanalization of previously occluded aneurysm. So a stent-graft was deployed to isolate the feeding artery of the rBAA from the descending aorta. The 3 months follow- up after the procedure included chest or back pain and computed tomographic angiography.
Results: The hospital stays of the 2 cases were 5 and 7 days. Chest or back pain was disappeared. There were no hospital deaths and late deaths. Computed tomographic angiogram showed no recanalization and no hemothorax. These 2 patients have not reported any complications up to now.
Conclusion: Aortic stent graft combined with aneurysm embolization is a minimally invasive, effective and safe method for rBAA.
