Bronchial artery aneurysm (BAA) is a rare disease, for which early treatment is recommended due to the risk of rupture often resulting in severe consequences. We report a case of successful treatment of an asymptomatic BAA by selective branch embolization combined with thoracic endovascular aortic repair (TEVAR). A 68-year-old man was accidentally found to have a bronchial artery aneurysm by computed tomography. The distance from the origin of the bronchial artery to the aneurysm was only 6 mm, at which branches were found. The BAA was completely excluded by selective branch coil embolization and deployment of a thoracic stent graft to cover the orifice of the BAA. Angiography confirmed that there was no endoleak. Selective branch embolization of BAA combined with TEVAR is effective to completely occlude the blood stream to BAA.
支气管动脉动脉瘤（BAA）是一种罕见疾病，因其破裂风险常导致严重后果，故建议早期治疗。我们报告一例通过选择性分支栓塞联合胸主动脉腔内修复术（TEVAR）成功治疗无症状BAA的病例。一名68岁男性通过计算机断层扫描意外发现患有支气管动脉动脉瘤。支气管动脉起源至动脉瘤的距离仅6mm，在此处发现有分支。通过选择性分支弹簧圈栓塞及植入胸主动脉覆膜支架覆盖BAA开口，BAA被完全隔绝。血管造影证实无内漏。BAA的选择性分支栓塞联合TEVAR可有效完全阻断BAA的血流。
