过度灌注综合征是颈动脉内膜切除术(CEA)后的一种少见而又十分严重的并发症。最近,Neurosurgery报道利用近红外光谱分析(nea-infared spectroscopy)进行术中经颅局部脑氧饱和度(rSO_2)监测能够可靠地预测术后发生过度灌注综合征的危险性。 Ogasawara等对50例同侧颈内动脉狭窄(≥70％)患者CEA治疗时进行术中rSO_2监测,同时在术前和术后即时通过SPECT评价患者的脑血流(CBF)。结果发现,6例CEA术后出现过度灌注(定义为与术前相比
Over-perfusion syndrome is a rare and very serious complication after carotid endarterectomy (CEA). Recently, Neurosurgery reported that the use of nea-infared spectroscopy for intraoperative monitoring of intracranial regional cerebral oxygen saturation (rSO_2) reliably predicted the risk of postoperative over-infusion syndrome. Ogasawara et al performed intraoperative rSO_2 monitoring on 50 patients with ipsilateral carotid artery stenosis (≥70%) undergoing CEA. Cerebral blood flow (CBF) was assessed by SPECT immediately before and immediately after surgery. The results showed that 6 patients after CEA over-perfusion (defined as compared with preoperative
