Prognostic factors of cerebral revascularisation in acute ischemic stroke at Hanoi Heart Hospital

Abstract

Background: Considering the effectiveness of treatment for acute ischemic stroke (AIS)patients, the most expected method is immediate revascularization using intravenous thrombolysis or mechanical thrombectomy, or both methods. Objective: “Find factors related to post-treatment outcomes of acute ischemic stroke patients undergoing cerebral revascularization”. Method: Cross-sectional, prospective, descriptive analysis with convenient sample size. Results: From February 2018 to August 2021, 83 patients were hospitalized with a diagnosis of acute ischemic stroke or acute ischemic stroke and had cerebral revascularision either by thrombolysis or mechanical devices or both. 6.02% of them had cerebral thrombosis with mechanical devices and stenting of cerebral/carotid arteries. Mean age was 66.37±11.82 (range 31to 91 years). Mean NIHSS score was 12.57±6.70. The rate of complete recanalization was 91.56%. The mRS score of 0-2 points accounted for 48.19% at the time of discharge and 54.21% at 30 days after discharge. The rate of death or severe illness at discharge accounted for 14.45%. 30 days all-cause mortality after discharge accounted for 25.3%. Conclusion: The rate of complete reperfusion in patients with acute cerebral infarction at Hanoi Heart Hospital and good recovery rate is quite high. Factors that related to the treatment efficacy of patients with acute ischemic stroke were NIHSS score, ASPECT score, occlusion site, pre-reperfusion parenchymal damage and the selection of appropriate reperfusion measures.
