CTICasesBPA-Related Pulmonary Artery Rupture
Imaging findings
CT chest obtained after balloon pulmonary angioplasty (BPA) shows a massive right-sided hemothorax, mediastinal shift, and active contrast extravasation (blush) within a large parenchymal hematoma in the right lung.
Key takeaways
Balloon pulmonary angioplasty (BPA) is an effective treatment for distal CTEPH, but carries risks of vascular injury. Pulmonary artery rupture or perforation by the wire or balloon can cause severe, life-threatening hemoptysis and hemothorax, requiring urgent transcatheter coil embolization.
