気管支動脈瘤に対するコイル塞栓術の1例

Coil Embolization of Bronchial Artery Aneurysm；Report of a Case

はじめに　気管支動脈瘤は非常にまれであると報告されているが1～3），経過観察中に破裂して気管支内穿破から気道出血，あるいは縦隔内出血により重篤な状態に陥る場合がある．したがって，的確な診断と，瘤径・部位により適切な治療が重要である．われわれは，胸部不快感を主訴とした気管支動脈瘤を経験したので報告する．

An 82-year-old male was admitted due to mild chest discomfort. Enhanced computed tomography showed a large bronchial artery aneurysm （BAA） of 26×27 mm at the left hilus. To avoid the rupture of BAA, coil embolization alone was performed. There has been no enlargement of BAA for these 4 years. In general, coil embolization only should be indicated in a patient with BAA with a stalk because of thoracic endovascular aortic repair （TEVAR） being off-label and low cost performance. TEVAR would be considered as a last resort only in case of enlarging BAA even after coil embolization.
