1觉醒型卒中的溶栓治疗一项新的研究显示,觉醒型卒中的溶栓治疗安全可行。既往研究表明,在发生卒中后弥散加权成像(DWI)序列立刻显示出阳性,而反映水肿的液体衰减反转恢复序列(FLAIR)则在3~4 h后显示出阳性。约有30%卒中为觉醒型卒中,觉醒型卒中因为无法准确地判断发病时间,因而在选择溶栓治疗时受到制约。这项研究(MR WITNESS)利用影像学手段判断未知发病时间的患者是否适合应用组织型纤溶酶原激活剂(t PA)进 Thrombolytic therapy in wakeful stroke One new study shows that thrombolytic therapy in arousal stroke is safe and feasible. Previous studies have shown that DWI sequences immediately after stroke have been shown to be positive, while FLAIR, which reflects edema, has been shown to be positive after 3 to 4 hours. Approximately 30% of stroke is arousal stroke. Arousal stroke is restricted in choosing thrombolytic therapy because it can not accurately determine the onset time. The study (MR WITNESS) used imaging to determine if patients with unknown onset were eligible for tissue plasminogen activator (t PA)
