But the increasing use of alteplase in ischemic stroke has made some complications more evident. Angioedema is a rare but potentially life-threatening complication of alteplase treatment. Only a few studies have examined the incidence of angioedema after treatment with alteplase for stroke.METHODS: A 75-year-old man complaining of right hemiparesis was admitted to our emergency department. He was diagnosed as having acute ischemic stroke, and alteplase infusion was given two hours after the onset of stroke symptoms. Immediately after the completion of infusion he was noted to have a large swollen tongue.RESULTS: His neurological symptoms resolved gradually within 4 hours, whereas his upper extremity strength improved to 4/5 and lower extremity 5/5. Lingual edema resolved within 16 hours without any complication. He died from presumed nosocomial infection 5 days later.CONCLUSIONS: Lingual angioedema may appear as a possible complication in patients who were treated with alteplase. The management of these patients should be very careful.展开更多

Methods: a total of 92 patients with acute mild ischemic stroke admitted from September in 2019 to March in 2020 were selected and divided into control group and observation group, with 46 cases in each group. The control group received conventional treatment, and the observation group received intravenous thrombolytic therapy with alteplase. The neurological function deficit, therapeutic effect and safety of the two groups were compared. Results: Before treatment, there was no statistical difference in NIHSS scores between 2 groups (P > 0.05). After treatment, the scores of both groups decreased, and the NIHSS scores of the observation group at different stages decreased more than that of the control group, with statistical significance (P < 0.05). The effective rate of observation group was significantly higher than control group. The complication rate of the observation group was lower than that of the control group. Conclusion: intravenous thrombolysis with alteplase is effective in treating acute mild ischemic stroke. It can be seen that the neurological function deficit has been significantly improved, with fewer complications. It is a treatment method with guaranteed safety and effectiveness, which is worthy of clinical promotion.展开更多

Methods: 86 patients with acute ischemic stroke admitted to our hospital by medical staff were selected for comprehensive data analysis and discussion on the individual condition of the patients. The patients were selected from June 2020 to May 2022 for research. After analyzing the condition of the patients, the patients were randomly divided into two groups. All patients met the test requirements and were recorded as the control group (n43) and the experimental group (n43) according to the experimental habits. The patients in the control group were treated only with alteplase, while the patients in the experimental group were treated with butylphthalide. After the treatment, the medical staff assessed the neurological deficit of the patients based on the NIHSS Stroke Scale to confirm the rehabilitation status of the patients. Results: compared with the control group, the NIHSS score of the experimental group was significantly lower than that of the control group, and the FMA score of the experimental group was significantly higher than that of the control group (P < 0.05). The MoCA score and MMSE score of the experimental group were higher than those of the control group (P < 0.05), and the effect of the experimental group was better than that of the control group (P < 0.05). Conclusion: the condition of patients with acute ischemic stroke is very complicated, and researchers found that the combined use of drugs can improve the treatment effect of patients. The application of butylphthalide combined with alteplase in the treatment of patients can improve the individual condition of patients, which is very good for the subsequent treatment of patients and the recovery of patients condition.展开更多

文摘Background:The occurrence of early neurological deterioration following intravenous thrombolysis(IVT)is considered a particularly ominous clinical event and is strongly correlated with poor outcomes.Initiating tirofiban within 24 h after IVT has been suggested as a better treatment option to achieve long-term functional outcomes.However,the rationality of this remedy is a controversial.The purpose of the study was to evaluate the safety and efficacy of early intravenous tirofiban administration after IVT in patients with acute ischemic stroke(AIS).Methods:Databases including PubMed,EMBASE,Cochrane Library,and Web of Science were searched for clinical trials on early tirofiban implementation after IVT in patients with AIS from inception to September 2022.Odds ratios(ORs)were generated for dichotomous variants via meta-analysis using STATA 17.0 MP.Results:Five clinical trials with 725 patients were eligible.The study outcomes demonstrated that early tirofiban administration after IVT was not associated with symptomatic intracranial hemorrhage(OR,0.78;95%confidence interval(CI),0.22–2.74;P=0.70),asymptomatic intracranial hemorrhage(OR,1.11;95%CI,0.52–2.37;P=0.80),systemic bleeding(OR,0.97;95%CI,0.42–2.23;P=0.94),and death(OR,1.05;95%CI,0.47–2.31;P=0.91),but may reduce the incidence of early neurological deterioration(OR,0.09;95%CI,0.02–0.50;P=0.01),and was significantly associated with 90-day excellent(modified Rankin scale score 0–1)(OR,2.01;95%CI,1.35–3.02;P=0.00)and favorable(modified Rankin scale score 0–2)(OR,2.30;95%CI,1.63–3.23;P=0.00)functional outcomes.Conclusion:The early intravenous administration of tirofiban after IVT in patients with AIS may be a safe and effective treatment strategy that improves long-term neurological functional outcomes without increasing the risk of adverse events.
文摘Objective: to investigate the clinical safety and efficacy of intravenous thrombolysis with alteplase in the treatment of acute mild ischemic stroke. Methods: a total of 92 patients with acute mild ischemic stroke admitted from September in 2019 to March in 2020 were selected and divided into control group and observation group, with 46 cases in each group. The control group received conventional treatment, and the observation group received intravenous thrombolytic therapy with alteplase. The neurological function deficit, therapeutic effect and safety of the two groups were compared. Results: Before treatment, there was no statistical difference in NIHSS scores between 2 groups (P > 0.05). After treatment, the scores of both groups decreased, and the NIHSS scores of the observation group at different stages decreased more than that of the control group, with statistical significance (P < 0.05). The effective rate of observation group was significantly higher than control group. The complication rate of the observation group was lower than that of the control group. Conclusion: intravenous thrombolysis with alteplase is effective in treating acute mild ischemic stroke. It can be seen that the neurological function deficit has been significantly improved, with fewer complications. It is a treatment method with guaranteed safety and effectiveness, which is worthy of clinical promotion.
文摘Objective: The medical staff randomly selected two groups during the research to explore and analyze the control experiment with the control score, and to explore the effect of butylbenzene peptide in the treatment of patients with acute ischemic stroke. Methods: 86 patients with acute ischemic stroke admitted to our hospital by medical staff were selected for comprehensive data analysis and discussion on the individual condition of the patients. The patients were selected from June 2020 to May 2022 for research. After analyzing the condition of the patients, the patients were randomly divided into two groups. All patients met the test requirements and were recorded as the control group (n43) and the experimental group (n43) according to the experimental habits. The patients in the control group were treated only with alteplase, while the patients in the experimental group were treated with butylphthalide. After the treatment, the medical staff assessed the neurological deficit of the patients based on the NIHSS Stroke Scale to confirm the rehabilitation status of the patients. Results: compared with the control group, the NIHSS score of the experimental group was significantly lower than that of the control group, and the FMA score of the experimental group was significantly higher than that of the control group (P < 0.05). The MoCA score and MMSE score of the experimental group were higher than those of the control group (P < 0.05), and the effect of the experimental group was better than that of the control group (P < 0.05). Conclusion: the condition of patients with acute ischemic stroke is very complicated, and researchers found that the combined use of drugs can improve the treatment effect of patients. The application of butylphthalide combined with alteplase in the treatment of patients can improve the individual condition of patients, which is very good for the subsequent treatment of patients and the recovery of patients condition.

文摘Aim:The rate of thrombolysis in Chinese acute ischemic stroke(AIS)was low and little was known about the long-term outcome.We aimed to compare the prognosis between thrombolysis and ordinary anti-platelet strategies in AIS.Methods:Patients,who were consecutively registered in our hospital from January 2005 to June 2012,were retrospectively studied.Inclusion criteria:(1)primary diagnoses of cerebral infarction coded with implantable cardioverter defibrillator-10 I63 to I69;(2)symptoms onset to treatment time(OTT)within 6 h;(3)thrombolysis with alteplase(TROM)or ordinary anti-platelet therapy(ANTP).Exclusion criteria:(1)symptoms and signs diminished rapidly without apparent neurological deficits;(2)no visible lesions on diffusion weighted image in magnetic resonance imaging;(3)cerebral infarction caused by serious metabolic in-balance or infections.The endpoints were defined as favorable(modified Rankin Scale 0-2)or being survival.Proportions of favorable outcome or survival were estimated by Kaplan-Meier curve and Cox regression.Results:One hundred and sixty eight cases were analyzed.Ninety one were in TROM and 77 in ANTP.Male accounted for 82(48.8%)and female 86(51.2%).The median of age was 74[interquartile range(IQR)67-79],national institute of health stroke scale(NIHSS 9)(IQR 5-17)and OTT 3.9 h(IQR 3.0-4.8)respectively.The median length of follow-up was 112(IQR 63.4-163.8)weeks.By the end of December 31,2012,87 patients(51.8%)reached favorable outcome while 81(48.2%)unfavorable.Forty five(26.8%)cases deceased.Kaplan-Meier curve estimation showed a longer favorable period of time in TROM than those in ANTP(212 weeks 95%confidence interval(CI)169.5-254.5 vs.126.9 weeks 95%CI 105.2-148.6;Log-Rank test x^(2)=19.632,P=0.000),while no significance was seen in survival time(258.0 weeks 95%CI 231.5-284.5 vs.160.8 weeks 95%CI 153.0-168.5;Log-Rank test x^(2)=2.427,P=0.119).In Cox regression,thrombolysis showed an independent protective effect for longer period of favorable outcome[202 vs.151 weeks,P=0.026,heart rate(HR)1.96,95%CI 1.958-3.540]and longer survival time instead(333 vs.170 weeks,P=0.000,HR 4.322,95%CI 1.942-9.618).The estimated proportion of favorable outcome in Chinese urban AIS was about 91%for 1 year and 50%for about 3.4 years,while the estimated proportion of survival was about 98.5%for 1 year and 50%for about 5.3 years,respectively.Conclusion:Chinese urban AIS patients who underwent thrombolysis with alteplase might have a better long-term outcome than those receiving ordinary anti-platelet therapy.
