Pulmonary hypertension
Pulmonary thromboendarterectomy (PTE) is a surgical procedure that is used for chronic thromboembolic pulmonary hypertension. It is the surgical removal of an organized thrombus (clot) along with the lining of the pulmonary artery; it is a large and very difficult procedure that is currently performed in a few select centers. Case series show remarkable success in most patients.
