ObjectiveTo study the clinical efficacy of multi-modality image-guided arterial embolectomy beyond time window for the treatment of acute cerebral infarction (ACI). MethodsA total of 106 patients with ACI were divided into treatment group and control group according to the random number table method, with 53 cases in each group. The treatment group underwent multi-modality image-guided arterial embolectomy beyond time window, whereas the control group underwent intravenous thrombolysis. Operation-related indicators, success rate of vascular recanalization, pre- and postoperative neurological deficit severity, and postoperative complications were compared between the two groups. ResultsCompared to the control group, the treatment group obtained less vascular recanalization time and hospital stay, higher success rate of vascular recanalization (90.57% vs. 50.94%), lower total incidence rate of complications (3.77% vs. 20.75%) (all P＜0.05); there was no statistically significant difference in out-of-bed activity time (P＞0.05); the National Institute of Health Stroke Scale (NIHSS) scores and the modified Rankin scale (mRS) scores one day, one month and three months after surgery decreased in both groups compared to those before surgery, and the decrease was more significant in the treatment group (all P＜0.05). ConclusionMulti-modality image-guided arterial embolectomy beyond time window is safe and effective in the treatment of ACI, which can significantly shorten vascular recanalization time and hospital stay, improve the success rate of vascular recanalization, improve neurological deficits and facilitate the recovery of patients.
