Abstract
We report a case of a bronchial artery aneurysm accompanied by a bronchial artery to pulmonary artery fistula in which only coil embolization was performed.Post-embolization, the majority of patients face significant metal artifacts from stents or coils during routine CT scans, which can compromise the visibility of the images. In this case,we conducted a spectral CT scan with metal artifact reduction technology postoperatively to clearly visualize the coils and accurately evaluate the treatment's effectiveness.
