ABSTRACT
PURPOSE:
The aim of the present study was (i) to evaluate the safety and efficacy of aspiration thrombectomy in patients with M2 occlusions and (ii) to compare outcome of treatment of occlusion of different M2 segments. MATERIALS ANDMETHODS:
Between March 2016 and June 2019, 82 patients with acute ischemic stroke and isolated M2 occlusions were treated in cerebrovascular stroke center with aspiration thrombectomy as the first-line treatment. Functional outcomes of patients with different types of M2 occlusions were statistically compared. Multivariable logistic regression analysis was performed to determine the factors associated with good clinical outcome.RESULTS:
The mean age was 71.9 ± 13.4 years, 47.6% were men. Aspiration thrombectomy alone was utilized in 72.5% of patients, with 27.5% of patients being treated with a combination of aspiration thrombectomy and stent retriever. At the three-month follow-up, there was no statistically significant difference in functional outcome between different types of M2 occlusions (p = 0.662), however in the underpowered analysis because of the small sample size of patients, with good clinical outcome mRS 0-2 in 50% of all treated patients. Symptomatic intracranial hemorrhage was found in 6.1% of patients. Lower age (OR 0.932, 95% CI 0.878-0.988) and lower NIHSS score upon admission (OR 0.893, 95% CI 0.805-0.991) were independent predictors of good clinical outcome.CONCLUSION:
Aspiration thrombectomy appeared to be a safe and effective first-line treatment option for patients with M2 occlusion, being the first-line option for almost three-quarters of patients.Palavras-chave
