Abstract:
Bronchial artery aneurysms (BAA) are a rare but potentially life-threatening complications because of the massive hemothorax or hemoptysis that occurs with ruptures. A 79-year-old woman was transferred to our hospital because of the sudden onset of back pain, syncope, and subsequent hypotension. Computed tomography showed a left BAA with bilateral hemothorax and hemomediastinum. Transcatheter bronchial artery embolization failed because of the anatomical location, and she went into cardiopulmonary arrest. Cardiopulmonary resuscitation was performed with successful revival. Urgent thoracic endovascular aortic repair to cover the root of the left bronchial artery was successful, and she survived without any neurological deficits.
