觉醒型缺血性卒中与6 h内缺血性卒中CT灌注成像特点比较

Characteristics of CT perfusion imaging in wake-up ischemic stroke and ischemic stroke within 6 hours

摘要

摘要: 目的：比较觉醒型缺血性卒中（wake-up ischemic strokes，WUIS）与6 h内缺血性卒中（ischemic strokes，IS）的临床特征及CT灌注成像（CTP）特点。方法：WUIS患者38例（WUIS组），明确IS发病时间6 h内患者42例（对照组），均行多模式CT检查CT-CTP-CT血管成像（CTA）。结果：2组患者梗死区和半暗带区数量、体积与CTP模式差异均无统计学意义（P>0.05）；2组患者CTP、CT和MRI Alberta卒中项目早期CT评分（ASPECTS评分）差异均无统计学意义（P>0.05），初始CT ASPECTS评分均明显高于CTP及3 d后CT或MRI ASPECTS评分（P<0.01）；WUIS组NIHSS评分显著高于对照组（P<0.01）。结论：WUIS患者的CTP特点与发病6 h内IS患者类似。

Abstract: Objective:To compare the clinical and CT perfusion imaging(CTP) characteristics between the wake-up ischemic stroke(WUIS) and ischemic stroke(IS) within 6 hours.Methods:Thirty-eight patients with WUIS and 42 patients with IS within 6 hours were divided into the WUIS group and control group.All patients were examined using the multi-mode CT.Results:The differences of the number and size of infarct,and penumbra,and the CTP pattern between two groups were not statistically significant(P>0.05),and the differences of the ASPECTS scores of CT,MRI and CTP between two groups were not statistically significant(P>0.05).The ASPECTS score of initial CT was significantly higher than that of CTP and CT or MRI after 3 days(P<0.01).The NIHSS score in WUIS group was significantly higher than that in control group(P<0.01).Conclusions:The characteristics of CTP in WUIS patients are similar to the patients with IS within 6 hours.
