摘要:

脑血流灌注与脑血管病变情况是影响脑卒中患者溶栓治疗效果的重要因素。目前大量的研究着重于如何提高缺血性脑卒中治疗前的影像诊断精确性,而对于患者溶栓后结局的预估判断则很少受到重视。为此,我们设计了观察CT灌注与CT血管成像检查预测缺血性脑卒中患者溶栓后临床结局中价值的试验。纳入缺血性脑卒中患者52例进行CT灌注及CT血管成像检查,按不同分组比较临床结局,其中短期结局以24 h NIHSS评分评价,长期结局以3个月mRS评分评价。分组:(1)溶栓与未溶栓患者;(2)溶栓患者中CT血管成像显示有无血管狭窄;(3)溶栓患者中CT灌注成像显示有无血流不匹配;(4)根据两种检查的不同结果组合进行分组。在52例缺血性脑卒中患者中有29例接受了溶栓治疗,其短期结局好于未溶栓者23例。在溶栓患者29例中,CT灌注与CT血管成像检查结果都为阳性者13例(CTA检查存在血管狭窄且CTP检查存在血流不匹配)短期结局最佳,而长期结局在溶栓患者29例中各组别间差异不明显。结果说明,CT灌注成像与CT血管成像联合检查有助于预测缺血性脑卒中溶栓患者的短期临床结局,对长期结局预测作用不大。

Abstract:

 

Cerebral blood perfusion and cerebrovascular lesions are important factors that can affect the therapeutic efficacy of thrombolysis. At present, the majority of studies focus on assessing the accuracy of lesion location using imaging methods before treatment, with less attention to predictions of outcomes after thrombolysis. Thus, in the present study we assessed the efficacy of combined computed tomography (CT) perfusion and CT angiography in predicting clinical outcomes after thrombolysis in ischemic stroke patients. The study included 52 patients who received both CT perfusion and CT angiography. Patients were divided into the following groups to compare clinical outcomes: (1) thrombolyzed and non-thrombolyzed patients, (2) thrombolytic patients with CT angiography showing the presence or absence of a vascular stenosis, (3) thrombolytic patients with CT perfusion showing the presence or absence of hemodynamic mismatch, and (4) according to different CT angiography and CT perfusion results. Short-term outcome was assessed by the 24-hour National Institution of Health Stroke Scale score change. Long-term outcome was assessed by the 3-month modified Rankin Scale score. Of 52 ischemic stroke patients, 29 were treated with thrombolysis and exhibited improved short-term outcomes compared with those without thrombolysis treatment (23 patients). Patients with both vascular stenosis and blood flow mismatch (13 patients) exhibited the best short-term outcome, while there was no correlation of long-term outcome with CT angiography or CT perfusion findings. These data suggest that combined CT perfusion and CT angiography are useful for predicting short-term outcome, but not long-term outcome, after thrombolysis.
