研究目的:

比较rhTNK-tPA动脉溶栓+标准药物治疗与标准药物治疗对急性颅内中等血管闭塞的有效性和安全性  

Objectives of Study:

To compare the efficacy and safety of intra-arterial thrombolysis with rhTNK-tPA plus standard drug therapy versus standard drug therapy for acute medium vessel occlusion

药物成份或治疗方案详述:

动脉溶栓方法:将微导管放置于闭塞近端,如有可能尽量接触血栓并置于血栓内部(大脑中动脉供血区放置于M1段内侧豆纹动脉远端或更远处,大脑前动脉放置于A1段或更远处,大脑后动脉放置于P1段或更远处,小脑上动脉、小脑前下动脉和后下动脉均放置于起始段或更远处),经微导管给予rhTNK-tPA。首次给予0.0625mg/kg(以无菌注射用水配制成1.33mg/ml溶液,最大剂量6.25mg),以1ml/min匀速推注。推注完后5min复查造影,进行eTICI评分,若eTICI评分较基线评分有所提高或造影剂外渗则给药结束,否则以相同剂量和速度重复给药一次,给药结束后5min再次复查造影评估eTICI评分。 

Description for medicine or protocol of treatment in detail:

Arterial thrombolysis protocol: the microcatheter was placed in the proximal end of the occlusion,and, if possible, contacting the thrombus or placed within the thrombus (the microcatheter was placed in the M1 segment for MCA territory, A1 segment for ACA territory, P1 segment for PCA territory, beginning segment for SCA, AICA or PICA). rhTNK-tPA was given via microcatheter. For the first time 0.0625mg / kg of rhTNK-tPA(1.33 mg/ml solution for sterile injection, maximum dose of 6.25mg) was infused at a uniform speed of 1 ml/min. After the infusion, the angiography was performed within 5min and the eTICI score was assessed. If the eTICI score improved from the baseline, or hemorrhage was suspected, the administration was suspended, otherwise another infusion was repeated at the same dose and speed, and the angiography and eTICI score was performed again 5min after the infusion.

随机方法(请说明由何人用什么方法产生随机序列):

本研究采用分层区组中央随机方法,根据中心分层,利用中央随机系统设置区组,每中心设置入组试验组和对照组受试者比例为1:1。各中心采用竞争入组的方式进行入组。随机分配患者将根据中心分层。

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

This study employed a stratified block randomization method. Based on center stratification, a central randomization system was used to create blocks, with a 1:1 ratio of trial group to control group for participants at each center. The block size for stratified randomization was set at 4, and enrollment was conducted through competitive recruitment at each center.
