嗄声を契機に発見された気管支動脈瘤の1例

Bronchial Artery Aneurysm with Hoarseness；Report of a Case

はじめに　気管支動脈瘤は比較的まれな疾患であるが，破裂による大量出血で致死的となりうるため，気管支動脈塞栓術（BAE）などの適切な治療が必要である．われわれは嗄声を契機に発見された気管支動脈瘤の1例を経験したので報告する．

The patient was a 72-year-old man with a history of bronchiectasis. He was admitted to our hospital for an examination of hoarseness. Chest computed tomography （CT） showed bronchiectasis in the bilateral lungs and bronchial artery aneurysm in the mediastinum. To prevent rupture of the aneurysm, we imaged the bronchial artery aneurysm by selective bronchial artery angiography and performed bronchial artery embolization （BAE） with 19 platinum coils. Three months after successful BAE, his hoarseness had improved, and the bronchial artery aneurysm was reduced in size after 12 months. To our knowledge, this is the 1st report of BAE improving hoarseness due to bronchial artery aneurysm.
