Angiographic findings. AÂ Selective digital subtraction angiography (DSA) of the right subclavian artery. Consistent with contrast-enhanced computed tomography image, the continuity from the right subscapular artery to the left pulmonary ligament artery (PLA) (arrow) is shown. BÂ and C Selective DSA of the left PLA. Note that the abnormal proliferation of small vessels is visible at the peripheral side of the left PLA. The arrowheads in b indicate the reversal blood flow of pulmonary artery, suggesting the presence of a systemic-pulmonary artery shunt. The dashed arrow in c indicates the pseudoaneurysm
