Potential Factors Affected Safety and Efficacy of Transcatheter Plug Closure for Pediatric Hemoptysis with Anomalous Bronchial Arteries

Figure 3

A secondary DSA of recurrent cases that had undergone transcatheter occlusion. 3A: a targeted abnormal BA that originated from the aortic arch was detected, which led to recurrence; 3B: two BAs from the thoracic trunk were blocked off, and a tortuous artery was clearly displayed from the aortic arch; 3C: after transcatheter occlusion of the dilated BAs from the thoracic aorta, another abnormal BA from the abdominal BA was detected in a secondary DSA presentation, which led to a recurrence; 3D: a recurrent case of an abnormal BA was detected with a tortuous route and abnormal origin from the right subclavian artery.
