摘　　要：目的:评价头颅磁共振液体衰减反转恢复序列(MR-FLAIR)增强对颈动脉支架植入术(CAS)后高灌注综合征(HPS)的诊断和预测作用。方法:选择CAS患者共46例,术前及术后查经颅多普勒超声(TCD)、头颅CT、头颅CT灌注(CTP),术后48 h内行头颅MR检查,重点检查FLAIR增强。结果:46例患者中发生HPS 7例,MR-FLAIR增强阳性符合率为85.7%,高于CT及无增强MR(P<0.05),阴性符合率为97.4%,高于TCD、CTP(P<0.05)。结论:头颅MR-FLAIR增强可以作为诊断和预测的CAS术后HPS的理想方法。Objective： To assess the role of cranial magnetic resonance （MR） imaging with enhancement fluid attenuated inversion recovery （FLAIR） in the diagnosis and prediction of cerebral hyperperfusion syndrome （HPS） after carotid artery stenting （CAS）. Methods： Forty six patients underwent carotid artery stenting （CAS） were included. Transcranial doppler （TCD）, cranial computer tomography scanning （CT） and perfusion cranial computer tomography （CTP） were performed before and after CAS. Enhanced cranial MR-FLAIR were performed within 48 hours after CAS. Results： Of all 46 patients, HPS developed in 7 cases. The positive accordance rate of enhancement MR-FLAIR was 85.7%, higher than that of CT and non-enhancement MR （P〈0.05）, and the negative accordance rate was 97.4%, higher than that of TCD and CTP （P〈0.05）. Conclusion： Enhancement cranial MR-FLAIR can identify patients at risk for post-CAS HPS.
