This study aimed to identify predictive factors for mortality within 3 months after mechanical thrombectomy for acute ischemic stroke patients. The study found that a low success rate of recanalization was a significant predictor of 3-month mortality.
Objective This study aims to determine predictive factors of mortality within 3 months after mechanical thrombectomy (MT) for patients with acute ischemic stroke (AIS). Methods This prospective cohort study was carried out at Assiut University stroke center in collaboration with Ain Shams University Egypt. Forty-four patients with anterior circulation AIS underwent MT between the first of January 2020 to the end of December 2020. They were evaluated for detection of death rates and identification of risks of 3-month mortality after MT. Results This study comprised 44 patients (52.3% male) with a mean age of 64.3 years. The mean time from onset to femoral arterial puncture was 304.1 min. The mean Alberta Stroke Program Early CT Score (ASPECTS) and National Institutes of Health Stroke Scale (NIHSS) score were 9.3 and 19.2, respectively. The 3-month mortality rate was 13.6%. Univariate analyses found that higher baseline NIHSS score (mean 22.2 vs. 18.7, p = 0.021), absence of good collateral (16.7% vs. 68.4%, p = 0.02), longer duration of procedure >= 60 min (66.7% vs. 23.7%, p = 0.032), lower rates of successful recanalization (83.3% vs. 28.9%, p = 0.01) and developing symptomatic intracerebral hemorrhage (33.3% vs. 5.3%, p = 0.026) were associated with 3-month mortality. Multivariate analyses found that low rates of successful recanalization (OR 0.081; 95% CI 0.009-0.780, p = 0.030) remained significant independent predictive factor of 3-month mortality. Conclusion Successful recanalization was an independent predictor of 3-month mortality after MT.
