Understanding CTEPH Diagnostic & Interventional Techniques

Dr. Lakhter outlines a practical diagnostic workup, emphasizing the Ventilation-Perfusion (V/Q) scan as the key screening test, supplemented by thin-cut CT pulmonary angiography and transthoracic echocardiography (TTE). He then explains how treatment decisions are made within a multidisciplinary framework, balancing medical therapy, surgical pulmonary endarterectomy (the curative gold standard for surgically accessible disease), and balloon pulmonary angioplasty (BPA) for patients with distal disease, residual pulmonary hypertension after surgery, or those who are not surgical candidates.
Drs. Lichaa and Lakhter dive into a detailed procedural overview of BPA, including pulmonary artery anatomy resources, pulmonary angiography technique, access and equipment selection, lesion classification, and intraprocedural assessment using pressure wires and venous return patterns. Dr. Lakhter shares practical strategies to minimize complications, including undersized balloon sizing to reduce reperfusion pulmonary edema, routine post-procedure diuresis, and management of complications such as pulmonary artery injury and tamponade using Gelfoam, coils, and, in rare cases, vascular plugs. They finish the conversation with a closer look at typical BPA staging and treatment endpoints.
