Case of pulmonary artery thromboendarterectomy using cariopulmonary bypass under moderate hypothermia and flow modulation for sub massive pulmonary artery embolism

After acute or chronic pulmonary embolism, pulmonary hypertension develops in most patients. Pulmonary thrombo Endarterectomy is the definitive treatment especially if thrombolysis is contraindicated. Here we have a patient with a chronic thrombus in the pulmonary artery that required thrombo Endarterectomy on Cardio pulmonary bypass with moderate hypothermia and low flows. After removal of thrombus there was dramatic clinical improvement.
