Figure 2. Comparison of bronchial arteriography findings frontal views before and after bronchial artery embolization. (A) Digitally subtracted angiography demonstrated that the right bronchial arteries were abnormal, with hypertrophy and peripheral bronchopulmonary shunt (yellow triangle). (B) After embolization of the right bronchial artery with use of porous gelatin particles (Gelpart, Nippon Kayaku, Tokyo, Japan), digitally subtracted angiography indicated a reduction in blood flow through the abnormal right bronchial arteries. BA – bronchial artery.
