摘　　要：目的 探讨急性脑梗死患者的FLAIR图像上出现高信号血管征的范围与弥散加权成像范围的不匹配评估患者行血管内血栓切除术(EVT)后功能结局的预后价值。方法回顾性分析60例急性脑梗死发作后行血管内血栓切除术的患者,收集这些患者的FLAIR、DWI、FLAIR高信号血管征与DWI高信号不匹配、功能结果(mRS)以及其他临床相关数据,采用多元Logistic回归分析预测功能结果。结果功能结果良好组(36/60;60.0%)较功能结果不良组(24/60;40.0%)的FVHS-DW I不匹配高(85.29%对45.83%;t=12.371;P<0.001)。多变量Logistic回归分析表明,FVHS-DWI不匹配与良好的功能结局独立相关[OR (95%CI):0.179(0.042~0.494),P<0.001]。结论急性脑梗死患者EVT术前使用FVHS-DWI不匹配评估有助于预测急性脑梗死患者的功能结果。Objective To investigate the mismatch between the range of high-signal vascular signs on FLAIR images and the range of diffusion-weighted imaging in evaluating the prognostic value of functional outcomes after intravascular thrombectomy(EVT) in patients with acute ce rebral infa rction.Methods A retrospective analysis was performed on 60 patients with acute cerebral infarction who underwent intravascular thrombectomy.FLAIR,DWI,FLAIR high-signal vascular sign and DWI high-signal Mismatch(FVHS-DWI Mismatch),functional outcome(mRS),and other clinically relevant data were collected.Multiple logistic regression analysis was used to predict the functional results.Results Group with good functional results(36/60;60.0%) compared with poor functional outcome group(24/60;40.0%) had a high FVHS-DWI Mismatch(85.29% vs.45.83%;t=12.371;P<0.001).M ultiva riate logistic regression a nalysis showed that FVHS-DWI mismatch was associated with good functional outcomes Independent correlation [OR(95%CI):0.179(0.042~0.494),P<0.001].Conclusion The use of FVHS-DWI Mismatch before EVT is helpful in predicting functional outcomes in patients with acute ce rebral infa rction.
