Pulmonary arterial hypertension (PAH) is a severe complication of Pulmonary Embolism (PE). The primary
treatment method is thromboembolectomy with artificial circulation and cold cardioplegia. It is often
that difficulties come up when mobilizing and removing organized thrombi from the segmental branches
due to a blood discharge from bronchial vessels. For these difficulties to be overcome, usually circulatory
arrest under deep hypothermic conditions is used which has a number of negative effects. We applied
intermittent circulatory arrest (8-10 min) at a temperature of 23-24°С in 17 patients with postembolic pulmonary
hypertension. Studies have shown that this technique allows achieving a dry surgical field, performing
the surgery in the proper way as well as minimizing the negative effects of deep hypothermia and prolonged
circulatory arrest.
