Figure 2

DSA display for anomalous BAs. 2A: the two visible abnormal BAs originated from the thoracic and the abdominal aortas, jointly leading to vascular rupture; 2B: a tortuous BA was clearly presented from the right side of the thoracic trunk, which paralleled the right inferior lobar bronchus; 2C: the right BAs were displayed, and a normal BA paralleled the superior lobar bronchus, while two abnormal BAs with abnormal routes paralleled the inferior lobar bronchus; 2D: two tiny and tortuous arteries apparently repealed, respectively, and originated from the aortic arch and thoracic aorta, forming connecting branches and bleeding in the middle lobe of the right lung.
