ABSTRACT
The authors studied cerebral oxygen supply by means of cerebral oximetry in patients presenting with chronic pulmonary artery thromboembolism (PATE) at various stages of operation. The study was aimed at assessing cerebral oxygen supply while carrying out surgical treatment in patients with chronic PATE on the background of various methods of perfusion. Thromboendarterectomy (TEA) from the pulmonary artery with the use of circulatory arrest and craniocerebral hypothermia is accompanied by more pronounced impairment of oxygen supply of the brain with a decrease in the cerebral oxygenation indices by more than 30% from the baseline values. These alterations promote increased risk for the development of neurological complications in the early postoperative period. Using the technique of antegrade cerebral perfusion ensures a minimum decrease of cerebral oxygenation during TEA and contributes to a reduction of the risk for the development of neurological complications.
