Coil embolization of bronchial artery aneurysm with high flow bronchial artery-pulmonary artery fistula


We report a case of an asymptomatic 36-year-old man with a bronchial artery aneurysm in the right hilum. Selective angiography revealed a 25mmsaccular aneurysm and an efferent artery of the aneurysm forming a high flow bronchial artery-pulmonary artery fistula. Because of dilatation and tortuosity of the bronchial artery, the microcatheter could reach the efferent artery but not the fistula. Therefore, we embolized the fistula by sending microcoils through the bloodstream from the efferent artery to the fistula (the “flow-dependent” coil embolization technique), and further embolized the aneurysm by coil isolation and packing technique.
