Two-stage Treatment Using Balloon Pulmonary Angioplasty and Pulmonary Endarterectomy in a Patient with Chronic Thromboembolic Pulmonary Hypertension.

We performed a 2-stage procedure combining balloon pulmonary angioplasty and pulmonary endarterectomy for a high-risk chronic thromboembolic pulmonary hypertension patient with high pulmonary vascular resistance. First, balloon pulmonary angioplasty was performed for distal lesions to improve hemodynamics and decrease the surgical risk. Subsequently, pulmonary endarterectomy was performed for proximal lesions, and the hemodynamics and symptoms improved dramatically. Our strategy was therefore found to be useful for treating a high-risk chronic thromboembolic pulmonary hypertension patient.
