Hemoptysis due to Pulmonary Arteriovenous Malformation after Coil Embolization during Long-Term Follow-Up

Figure 3

(a) Coils of the cavity lesion were confirmed (arrow), but pulmonary angiography showed no extravasation or hypervascular inflammatory parenchymal lesions. (b) Angiography of the left bronchial artery showed hypervascular inflammatory parenchymal lesions around the coils of the cavity lesion (arrows). Thus, the left bronchial artery was the vessel most likely to be responsible for the hemoptysis symptoms. (c) The microcatheter was advanced to the target branch of the left bronchial artery. Angiography showed hypervascular inflammatory parenchymal lesions around the coils of the cavity lesion (arrows) and bronchial–pulmonary artery shunt (arrow head). Embolization was performed using gelatin sponge. (d) Angiography of the left bronchial artery showed a complete occlusion of the target branch.
