Pulmonary Endarterectomy - Post-surgery care

  • 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

Discharge advice

Pay attention to wound care

  • Stitches will gradually disappear as the wound heals
  • Use support pillow when coughing
  • For female patients, it is advisable to wear a bra for 24hrs for six to 12 weeks after the surgery to provide support and allow the wound to heal
  • Go to the nearest General Practitioner (GP) or polyclinic if there are wound discharges, redness, hot and tingly sensations or tenderness

Pulmonary endarterectomy medication


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

  • Warfarin: International Normalised Ratio (INR), a form of blood test, targets to be within 2-3
  • Other drugs which do not require INR check: Rivaroxaban, Apixaban or Darbigartran


Some patients may require this medication to remove excess water from the body.

Side effects of the medication

  • Frequent urination
  • Low blood pressure
  • Dehydration
  • Nausea and vomiting
  • Low potassium / sodium level cause arrhythmias
  • Muscle cramps
  • Dizziness

Oxygen Therapy

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.


  • Nutrition: A balanced diet is important to promote healing.
  • Exercise: It is recommended to resume daily activities.
  • Showering: Shower daily with back facing the shower head to prevent water spraying directly on the wound. Take note to keep surgical wound clean and dry.
  • Housework: Light housework is tolerable.
  • Driving: It is advisable to only resume driving in six to eight weeks’ time, after the surgery. Do place cushion on chest for better comfort.
