Pulmonary Endarterectomy - What is it for

Pulmonary endarterectomy (also known as PEA) is an open-heart surgery carried out for patients with chronic thromboembolic pulmonary hypertension (CTEPH). The operation is conducted to remove blood clots from the pulmonary arteries in the lungs to allow regular blood flow. 
The introduction of NHCS CTEPH programme, which started in 2016, is the first in Singapore to offer comprehensive treatment options for CTEPH patients, including pulmonary endarterectomy, balloon pulmonary angioplasty and medical therapy.

​Pulmonary endarterectomy is a curative and complex surgery. It involves placing the patient on heart-lung bypass machine support that will take over the function of the heart and lungs, and to allow the doctors to carefully remove the clots from the lungs. The whole operation takes about seven to eight hours and is undertaken by specially trained doctors and support staff, working closely as a team.

  • Patients who have undergone a PEA surgery will be warded for a week or two or as long as they are needed for observation. An electrocardiogram (ECG) monitor will continuously record the rhythm of the heart in the first few days after the surgery.
  • Physical therapy will slowly be introduced to strengthen the patient with light physical activities.
  • Patients who have duly recovered their strength and have stable conditions will be arranged for discharge
  • Follow-up appointments for regular check-ups will also be arranged at NHCS
