Abstract:Objective To investigate the clinical efficacy of recombinant tissue plasminogen activator (r-TPA) arterial thrombolysis combined with intravascular therapy in the treatment of cerebral infarction within 6 hours. Methods The data of 160 patients with acute cerebral infarction (ACI) admitted to our hospital from February 2017 to March 2019 were collected. According to the patient's family treatment plan, 80 patients in the observation group were treated with r-TPA+vascular intervention (intravascular treatment with stenting), 80 patients in the control group only received r-TPA arterial thrombolysis. NIHSS scores and ADL scores were compared before treatment, 24?h, 7?d, and 3 months after treatment. The recanalization of patients was observed, and adverse reactions and clinical prognosis were recorded. Results The NIHSS score and ADL score of the two groups were different at different time points (P?0.05), the NIHSS score and ADL score of the two groups were different (P?0.05), and the trend of the NIHSS score of the two groups was different (P?0.05). There was a difference in the trend of ADL score between the two groups (P?0.05). The revascularization rate in the observation group was 100% (76 cases of complete recanalization and 5 cases of partial recanalization), and the rate of vascular recanalization in the control group was 95% (62 cases of complete recanalization, 14 cases of partial recanalization, and 4 cases of nonrecanalization). The difference in revascularization rate between the two groups was statistically significant (P?0.05). Only 2 cases of cerebral infarction recurred in the observation group after treatment, and no death occurred. 12 cases of recurrent cerebral infarction in the control group after treatment, and 4 cases died due to cerebral infarction with cerebral hernia, the difference in prognostic data between the two groups is statistically significant (P?0.05). Conclusion The combination of r-TPA and endovascular treatment can improve the thrombolytic effect, promote the recovery of neurological function, improve the prognosis and have good safety. However, due to factors such as DSA technology and time-consuming preparation before vascular intervention, it may prolong the timing of thrombolytic treatment and offset the advantages of early arterial thrombolysis. It is recommended to develop an individualized thrombolytic therapy according to the patient's condition.
