Risk of Cerebral Complications of Surgical Treatment of Patients With Chronic Pulmonary Embolism

Abstract

Aim of the study was to assess risk of cerebral complications at the background of various methods of brain protection during surgery in patients with chronic pulmonary embolism (PE). We examined 61 patients aged 39-54 years operated because of chronic PE. Monitoring of cerebral oxygenation (rSO2, %) was performed at various stages of surgery. Neurological status was assessed in the immediate postoperative period. We conclude that antegrade cerebral perfusion was the most effective method of cerebral protection which was associated with reduction of risk of neurological complications in the early postoperative period. Application of full cardiac arrest at the background of craniocerebral hypothermia was associated with the most significant reduction of rSO2 and increased risk of impairment of neurological status in the early postoperative period.
