冠状動脈—気管支動脈吻合を伴った大動脈炎症候群の1例

A case of aortitis syndrome with anastmosis from left coronary artery to bronchial artery

　大動脈炎症候群は，大動脈・主分岐動脈・肺動脈などの弾性型動脈における非特異的炎症による疾患であり，大動脈弁閉鎖不全（aortic regurgitation　；　AR）や冠状動脈病変をきたすこともある。

　最近われわれは，発症後約10年経過した大動脈炎症候群末期の1例を経験し，ARと肺動脈狭窄と冠状動脈—気管支動脈吻合の合併を認めた。若干の文献的考察を加え報告する。

We reported a case of aortitis syndrome with about 10-year course from onset.

The patient was a 44-year old female suffering from a cardiac failure.

The angiogram revealed presence of aortic regur-gitation, pulmonary vascular lesions, anastomosis from left coronary artery to bronchial artery and hypervascularity of bronchial artery.

We considered the anastomosis from left coronary artery to bronchial artery as a collateral blood flow for the ischemic lesions of the lung.

We abandoned aortic valve replacement because of the severe pulmonary vascular lesions and of the pulmonary dysfunction.
