  • Title: Surgical Treatment of Chronic Thromboembolic Pulmonary Hypertension: Pulmonary Thromboendarterectomy.
    Author: Madani MM.

    Abstract:
    Pulmonary thromboendarterectomy (PTE), also referred to as pulmonary endarterectomy, is the definitive treatment for chronic thromboembolic pulmonary hypertension (CTEPH). The true incidence of CTEPH is unknown and difficult to ascertain; however, most experts agree that approximately 4% to 5% of all patients who have an acute episode of pulmonary embolism (PE) will continue to develop CTEPH. Based on an incidence rate of about 0.1% for acute PE, this translates into a CTEPH incidence of approximately 10,000 to 15,000 annually in the United States alone. Furthermore, there are patients with CTEPH who have no history of prior PE or deep vein thrombosis, adding to the estimated number. Despite these facts, the disease remains significantly underdiagnosed, and currently there are only about 300 PTEs performed nationwide, the majority of which are done at the University of California, San Diego (UCSD) Health System. The technical aspects of the procedure can be somewhat challenging and require meticulous and complete dissection of the entire pulmonary vascular tree, with the patient under profound hypothermic circulatory arrest. However, the determination of true CTEPH patients and those who would benefit from surgery can also be challenging and relies heavily on the experience of the CTEPH team. In this article, we will highlight some key points about the disease and describe the surgical techniques of PTE.
