OBJECTIVE: We aimed at determining the effectiveness of mechanical thrombectomy (MT) in patients with major vessel occlusion and infected with COVID-19, evaluating its clinical outcome and comparing it with non-COVID patients.

PATIENTS AND METHODS:  During the pandemic, 729 patients who underwent MT in stroke centers due to Acute Ischemic Stroke (AIS) with large vessel occlusion were evaluated. This study included 40 patients with a confirmed COVID-19 diagnosis by a positive PCR test between March 11, 2020, and December 31, 2020. These patients were compared to 409 patients who underwent MT due to major vessel occlusion between March 11, 2019, and December 31, 2019.

RESULTS: Of the patients with AIS who are infected with COVID-19, 62.5% were males, and all patients have a median age of 63.5 ± 14.4 years. The median NIHSS score of the COVID-19 group was significantly higher than that of the non-COVID-19 groups. Dissection was significantly more in the COVID-19 group. The mortality rates at 3 months were higher in the COVID-19 groups compared to non-COVID-19 groups.

CONCLUSIONS: This study revealed an increased frequency of dissection in patients with COVID-19. COVID-19-related ischemic strokes are associated with worse functional outcomes and higher mortality rates than non-COVID-19 ischemic strokes.
