The Effect of Intravenous Thrombolysis on Transient Ischemic Attack and Cerebral Infarction Patients Under the Guidance of Multimodal Magnetic Resonance Imaging

Abstract

Objective: To investigate the clinical effects of intravenous thrombolysis in the treatment of TIA (Transient Ischemic Attack) and cerebral infarction with multimodal MRI (magnetic resonance imaging), and to provide a reference for clinical diagnosis and treatment. Methods: Patients with acute cerebral infarction diagnosed and treated with intravenous thrombolysis were enrolled in the study. Multimodal MRI was performed to determine the location and type of cerebral infarction. Based on routine treatment and care, the rt-PA (Recombinant Tissue Plasminogen Activator) intravenous thrombolytic therapy was applied. The NIHSS (National Institutes of Health Stroke Scale) scores of patients before and after treatment were evaluated and compared to analyze the neurological prognosis. Results: The NIHSS scores after treatment were significantly lower than those before treatment, and the neurological prognosis was good. Three different forms of ACVS (asymmetric cortical venous signs) after treatment could be observed by SWI (drug-sensitive weighted imaging) images, which could help to assess the prognosis. Conclusion: Multimodal MRI could evaluate the type and severity of acute cerebral infarction. The rt-PA intravenous thrombolytic therapy could effectively promote the recovery of neurological functions in patients with cerebral infarction, which was worthy of clinical promotion.
