Figure 2. a–c.

Orthotopic bronchial arteries. Preembolization digital subtraction angiography (DSA) image (a) shows selective catheterization of common bronchial artery giving rise to hypertrophied right bronchial artery (black arrow) and left bronchial artery (white arrow) with parenchymal blush (white block arrow). Postembolization DSA image (b) shows contrast stasis in right bronchial artery (black arrow), obliterated left bronchial artery and no residual parenchymal blush suggestive of successful embolization. DSA image in a different patient (c) shows selective run of hypertrophied right intercostobronchial trunk giving rise to right bronchial artery (white arrow) and intercostal artery (black arrow).
