Figure 2.

Imaging and thrombus in CTEPH. A V/Q scan in the same patient showing multiple bilateral mismatched defects. B CT scan showing clear vascular mosaicism. C The white arrow highlights an angiographic “pouch” occlusion of the right interlobar vessel. The presence of organized thromboembolic disease is also evident by “web” narrowing of the proximal anterior upper lobe artery (green arrow). D The lateral right pulmonary arteriogram in the same patient shows another “web” narrowing (white arrow) of the proximal posterior upper lobe vessel not appreciated on the AP films.
