PTE: Pulmonary Thromboendarterectomy Surgery for Pulmonary Hypertension


UC San Diego Health is the worldwide leader for pulmonary thromboendarterectomy (PTE) surgery, also known as pulmonary endarterectomy (PEA), to treat chronic thromboembolic pulmonary hypertension (CTEPH).

Developed here at UC San Diego Health, PTE is a complex surgery that removes deadly chronic blood clots from major blood vessels in the lungs that cannot be treated with medication. Without treatment, these clots block off blood flow to the lungs, cause damaging vascular changes and pulmonary hypertension. This condition can lead to heart failure and death.

For individuals who are not candidates for PTE surgery, our team also offers balloon pulmonary angioplasty and medical therapy.
