a) Pulmonary angiography, showing a stenosis in the subsegment of the 10th segmental artery (anterior view); b) the catheter is introduced into a web stenosis; c) the wire is introduced between the fibrotic material and the balloon is inflated, leading to rupture of the web. d) Angiography after balloon pulmonary angioplasty shows an improvement of blood flow with better perfusion of the parenchyma and quick venous return. In contrast to pulmonary endarterectomy, the fibrous material is not removed from the arteries, but is crushed against the vessel wall.
