[Abstract] Objective To study the correlation between the total load of cerebral small vessel disease (CSVD) and the early deterioration of neurological function of patients with acute ischemic stroke (AIS) after intravenous thrombolysis. Methods AIS patients who received intravenous thrombolysis with recombinant tissue plasminogen activator (rt-PA) (within 4.5 hours after onset) in the Stroke Center of People′s Hospital of Jinan City from May 2019 to October 2020 were retrospectively included. The general data and clinical features of patients were recorded, and the total load of CSVD was evaluated within 48 hours after cerebral MR. According to CSVD total load score,patients were divided into the mild and moderate group (CSVD: 0-2 points) and the severe group (CSVD:3-4 points). Finally, the general data and clinical features of the two groups were compared to determine whether there are statistically significant differences between two groups. Results Among 155 objects,there were 95 cases in the mild and moderate group (CSVD:0-2 points) and 60 cases in the severe group (CSVD:3-4 points). There were no statistically significant differences in age, gender, and vascular risk factors between the two groups. The clinical data of the severe group? and the mild and moderate group showed that, there were statistically significant differences in END [9.47% (9/95) vs. 25.00% (15/60), χ2=6.774, P=0.009], HT [11.58% (11/95) vs. 40.00% (24/60), χ2=12.430, P=0.001] and SICH [7.37% (7/95) vs. 20.00% (12/60), χ2=5.460, P=0.020] (P<0.05). Conclusion There is a positive correlation between the severity of the total load of CSVD and the early deterioration of neurological function, hemorrhage transformation and symptomatic intracranial hemorrhage of AIS patients after thrombolysis.

急性缺血性卒中(Acute ischemic stroke,AIS)是因腦動(dòng)脈急性閉塞后引起的局限或全面性神經(jīng)功能缺損綜合征,目前重組組織型纖溶酶原激活劑(Recombinant human tissue-type plasiminogen,rt-PA)靜脈溶栓是急性缺血性卒中超早期治療有效的方法之一。雖然大部分患者可以在此治療后獲益,但仍有少數(shù)患者會(huì)在溶栓早期出現(xiàn)神經(jīng)功能惡化、出血轉(zhuǎn)化的情況。應(yīng)用美國(guó)國(guó)立衛(wèi)生研究院卒中量表(National institute of health stroke scale,NIHSS)評(píng)估神經(jīng)功能缺損程度并定義24 h內(nèi)溶栓前后NIHSS評(píng)分增加≥4分者為早期神經(jīng)功能惡化(Early neurological deterioration,END)[1]。出血性轉(zhuǎn)化(Hemorrhagic transformation,HT)是指 AIS后缺血區(qū)的腦血管恢復(fù)血流灌注而引起的繼發(fā)性出血,即在CT/MRI中出現(xiàn)新發(fā)的顱內(nèi)出血[2]。根據(jù)其對(duì)神經(jīng)功能缺損的影響程度將其分為癥狀性顱內(nèi)出血(Symptomatic intracranial hemorrhage,sICH)和無(wú)癥狀性顱內(nèi)出血(Asymptomatic intracranial hemorrhage),而歐洲急性卒中協(xié)作研究Ⅱ(the european cooperative acute stroke study,ECASS Ⅱ)將 sICH 定義為CT上有出血表現(xiàn)且前后NIHSS 評(píng)分增加≥4分或出現(xiàn)臨床惡化事件(包括嗜睡或偏癱加重),sICH 與不良預(yù)后相關(guān)[3]。
