[Cerebral oxygen supply in patients with chronic pulmonary artery embolism]
Abstract:
Aim of this study was to assess brain oxygen supply in patients with chronic pulmonary embolism (CPE) for elucidation of factors of risk of neurological complications in early postoperative period. We examined 34 patients with diagnosis of CPE. Mean duration of the disease was 3 (1.4-4.2) years. Data on baseline cerebral oxygenation, monitoring of brain oxygen during various stages of surgery, and level of cerebral oxygen supply in immediate postoperative period are presented. More than 40% lowering from initial values of parameters of cerebral oxygenation during circulatory arrest substantially increases risk of development of neurological complications in early postoperative period.
