Pulmonary Endarterectomy
PTE is surgery to remove blood clots and scar tissue from the arteries in your lungs. It is also called pulmonary endarterectomy (PEA). This surgery can potentially cure a condition called chronic thromboembolic pulmonary hypertension (CTEPH).
With CTEPH, blood clots get trapped within the walls of the arteries and develop scar tissue over time. Pressure in the lungs is high and breathing can be difficult. The blockage leads to high pressures in the arteries eventually leading to right heart failure and damage to the lungs.
