Sequential Combination of Balloon Pulmonary Angioplasty for Distal Lesions in the Left Pulmonary Artery Followed by Pulmonary Endarterectomy for Central Lesions in the Right Pulmonary Artery: A Case Report.

Pulmonary endarterectomy (PEA) is the gold standard treatment for chronic thromboembolic pulmonary hypertension (CTEPH). While balloon pulmonary angioplasty (BPA) is an emerging treatment for distal CTEPH, a standard therapeutic strategy for CTEPH with unilateral central lesions has yet to be established. Herein, we describe the successful treatment of a patient with CTEPH who underwent BPA for left distal lesions, followed by PEA for unilateral right central lesions, without serious complications. BPA before PEA may reduce perioperative complications by improving hemodynamics and contribute to a better clinical course by shortening deep hypothermic circulatory arrest time through reduction of the PEA treatment area. Depending on the anatomical characteristics of the lesions, this combination therapy should be discussed by a multidisciplinary CTEPH team.
