OBJECTIVE: Ischemic stroke is a neuroemergency condition highly treatable with thrombolysis and thrombectomy. Recently, observational studies have brought insights into clinical and imaging characteristics of wake-up stroke, which interested up to 25% of ischemic stroke patients. In clinical practice, wake-up strokes are usually not considered for reperfusion therapy. The aim of this study was to investigate the use CT perfusion imaging in patients with wake-up stroke and to assess the effect of neuroimaging information provided by CT perfusion maps on the efficacy and safety of thrombolysis and thrombectomy. PATIENTS AND METHOD: We studied 22 wake-up stroke (WUS) patients (13F/9M mean age) who underwent reperfusion therapy after the eligibility assessed by the CT perfusion imaging (< 50% core-to-penumbra ratio and negative CT perfusion). RESULTS: Mean National Institutes of Health Stroke Scale (NIHSS) was 8.1 ± 4.9 at admission while 3.3 ± 5.1 at discharge, significantly different from admission (p < 0.001). As many as ten patients had mRS lower than 3 at discharge. Intracranial hemorrhage occurred in five patients and caused symptoms worsening only in two patients (decrease of NIHSS score of 4 points) of which one patient died. CONCLUSION: The main finding of this study is that wake-up stroke with adequate selection by CT perfusion may benefit reperfusion treatment.

Abstract

OBJECTIVE: Ischemic stroke is a neuroemergency condition highly treatable with thrombolysis and thrombectomy. Recently, observational studies have brought insights into clinical and imaging characteristics of wake-up stroke, which interested up to 25% of ischemic stroke patients. In clinical practice, wake-up strokes are usually not considered for reperfusion therapy. The aim of this study was to investigate the use CT perfusion imaging in patients with wake-up stroke and to assess the effect of neuroimaging information provided by CT perfusion maps on the efficacy and safety of thrombolysis and thrombectomy. PATIENTS AND METHOD: We studied 22 wake-up stroke (WUS) patients (13F/9M mean age) who underwent reperfusion therapy after the eligibility assessed by the CT perfusion imaging (< 50% core-to-penumbra ratio and negative CT perfusion). RESULTS: Mean National Institutes of Health Stroke Scale (NIHSS) was 8.1 ± 4.9 at admission while 3.3 ± 5.1 at discharge, significantly different from admission (p < 0.001). As many as ten patients had mRS lower than 3 at discharge. Intracranial hemorrhage occurred in five patients and caused symptoms worsening only in two patients (decrease of NIHSS score of 4 points) of which one patient died. CONCLUSION: The main finding of this study is that wake-up stroke with adequate selection by CT perfusion may benefit reperfusion treatment.
