Histology of a pulmonary artery treated by balloon pulmonary angioplasty (BPA) [cited from Ref. (38)]. (A) A large lumen was formed due to dissection in the media of a pulmonary artery by BPA (elastic tissue stain, low magnification; bar: 1 mm). (B) High magnification of the dissection site [square in (A); elastic tissue stain]. Dissection occurred in the middle of the media (arrow). Newly formed intima is observed on the inner surface (arrowheads). One of the recanalized lumina in the organized thrombi is also seen on the right.
