Chronic thromboembolic pulmonary hypertension (CTEPH) is a condition whereby lung pressures are raised due to chronic blood clots in the lungs. Pulmonary endarterectomy (PEA) is potentially the curative treatment option for CTEPH. It is an open-heart surgery carried out to remove blood clots from the arteries in the lungs to help improve blood flow.
Pulmonary endarterectomy is a complex but potentially curative surgery for CTEPH. It involves placing the patient on a heart-lung bypass machine support that will take over the function of the heart and lungs as well as lowering the body temperature. This will allow the doctors time to carefully remove the clots from the lungs. The whole operation usually takes about seven to eight hours and is undertaken by a specially trained team of doctors and support staff.
PEA surgery can cause significant improvement in symptoms of breathlessness and help bring pulmonary artery pressures back to normal. Patients with CTEPH who underwent PEA surgery generally reported improved quality of life.
Less Common Risks
Please follow the below instructions to prepare for your PEA surgery:
Pay attention to wound care
Watch out for complications
Seek medical consultation with your doctor at the Cardiac Clinics / Specialist Outpatient Clinic or at the Department of Emergency Medicine of Singapore General Hospital (after office hours), if any of the following conditions occurs:
Anticoagulations are blood-thinning medications that help prevent blood from clotting. Patients who are on anticoagulations need to take them for long-term or in most cases, for the rest of their life.Blood-thinning medications
Some patients may require this medication to remove excess water from the body.
Side effects of the medication
Some patients may require oxygen therapy after discharge to help them breathe better and improve their quality of life.Pulmonary Vasodilatators
Some patients may require specific drugs to lower the blood pressure in the lungs. These are only given to those who have persistent pulmonary hypertension after the surgery.
