摘　　要：目的探讨血管内治疗(EVT)后急性缺血性脑卒中(AIS)患者发生恶性脑水肿(MBE)的影像学预测因素。方法在西南医科大学附属医院接受EVT后的AIS患者51例,根据是否发生MBE分为MBE组和非MBE组。统计分析患者的特定部位灌注参数、造影剂外渗情况及临床资料。结果51例患者中,13例发生MBE。MBE组豆状核相对平均通过时间(rMTT)更大、造影剂外渗发生率更高、美国国立卫生研究院卒中量表(HIHSS)评分更高(P<0.05)。结论较大的豆状核rMTT值、造影剂外渗对于AIS患者EVT后MBE发生的早期预测有重要意义。Objective To investigate the imaging predictors of malignant brain edema(MBE)after endovascular treatment(EVT)of acute ischemic stroke(AIS).Methods A retrospective analysis was performed on 51 AIS patients who received EVT in our hospital.According to the occurrence of MBE,the patients were divided into MBE group and non-MBE group.The perfusion parameters at patients'specific sites,contrast agent extravasation and general data were statistically analyzed.Results Of the 51 patients,13 had MBE.Patients in the MBE group had a higher rMTT value of the lentil nucleus,higher incidence of contrast extravasation and greater HIHSS score when compared to the patients in the non-MBE group(P<0.05).Conclusion Ahigher rMTT value of the lentil nucleus and contrast extravasation are significant for early prediction of MBE after EVT in AIS patients.
