Rescue Implantation of Covered Stent in Pulmonary Artery Rupture During Balloon Pulmonary Angioplasty.

The ring-like lesions in chronic thromboembolic pulmonary hypertension (CTEPH) patients are sometimes difficult to dilate because they are hard and fibrotic. For this reason, slightly oversized balloons are used; however, this may result in an increased risk of vessel rupture. We present a 62-year-old female with residual pulmonary hypertension after pulmonary endarterectomy for CTEPH who underwent balloon pulmonary angioplasty (BPA). Implantation of a covered stent not only protects the ruptured vessel, but also keeps perfusion in the future.
