研究目的:

基于计算机断层扫描灌注影像(Computed tomography Perfusion,CTP),探究在接受静脉溶栓治疗的AIS患者中,静脉溶栓前的CST低灌注与静脉溶栓后的uEND和3月神经功能结局的关系。  

Objectives of Study:

Based on Computed tomography Perfusion (CTP), this paper investigates the relationship between low CST perfusion before intravenous thrombolysis and uEND and neurological function outcome 3 months after intravenous thrombolysis in AIS patients.

药物成份或治疗方案详述:

 

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1、发病9小时内接受IVT治疗; 2、IVT前行CTP检查。

Inclusion criteria

1.Received IVT within 9 h after the onset; 2.Underwent baseline CT perfusion (CTP) before IVT.

排除标准:

1、24 h复查影像出现脑实质出血(Parenchymal hematoma,PH)转化,定义为出血转化>30%梗死灶大小,有明显占位效应出血或远离梗死灶出血; 2、24小时内出现恶性脑水肿,定义为伴有脑肿胀和中线偏移,伴意识改变; 3、早期复发性缺血性卒中和早期癫痫发作; 4、由于运动伪影或大的损伤而导致图像后处理失败。

Exclusion criteria:

1.Had cerebral arenchymal hemorrhage (PH) within 24 h, which was defined as a hematoma in ≤ 30% of the infarcted area with some slight space-occupying effect or blood clots in > 30% of the infarcted area with a substantial space-occupying effect; 2.Had malignant brain edema within 24 h, which was defined as concomitant imaging which showed brain swelling and midline shift which were associated with worsening of consciousness; 3.Had early recurrent stroke within 24 h, which was defined as the new neurological symptoms along with the evidence of corresponding ischemic lesions on follow-up cranial CT or MRI, which suggested the involvement of initially unaffected vascular area ; 4.Finally, if they had failed image post-processing due to movement artifacts or huge previous lesions.

随机方法(请说明由何人用什么方法产生随机序列):

两位经验丰富的神经科医师检查了符合入组标准的灌注图像,并在处理后的 CT 灌注图像上明确 CST 对应层的位置,以及低灌注是否累及 CST 区域。CST 区域包括放射冠、半卵圆中心、侧脑室、内囊后肢、脑干区。CST 低灌注定义为低灌注累及 CST 区域。非 CST 低灌注定义为 CST 以外区域出现低灌注或无灌注。

Randomization Procedure (please state who generates the random number sequence and by what method):

Two experienced neurologists examined all perfusion images and identified the site of CST in the corresponding layers on post-processed CT images, and whether hypoperfusion involved CST areas, including corona radiata,central semi-elliptic, lateral ventricle, the posterior limb of the internal capsule, and brainstem area. CST hypoperfusion was defined as hypoperfusion involving CST areas. Non-CST hypoperfusion was defined as hypoperfusion involving areas other than CST and no hypoperfusion
