Six patients undergoing routine coronary artery bypass surgery were examined by magnetic resonance imaging of the brain before surgery, immediately afterwards, and 6-18 days later. Brain swelling was visible in all six patients on the immediate postoperative scan. In five patients who had later scans the swelling had subsided. No major neurological deficits were seen, and the patients were extubated successfully within 3 h of the operation. The mechanism of the cerebral swelling is uncertain, but it may provide insight into the cause of neurophysiological deficits seen after coronary artery surgery.
对6例接受常规冠状动脉搭桥手术的患者在术前、术后即刻以及术后6 - 18天进行脑部磁共振成像检查。术后即刻扫描显示,所有6例患者均出现脑肿胀。在5例接受后期扫描的患者中,肿胀已消退。未观察到严重的神经功能缺损,并且患者在手术3小时内成功拔管。脑肿胀的机制尚不确定,但它可能有助于深入了解冠状动脉手术后出现的神经生理缺陷的原因。
