WSC 2022 | Endovascular thrombectomy outcomes in patients with ischemic stroke due to medium vessel occlusion

Nishita Singh, MD, University of Calgary, Calgary, Alberta, Canada, shares registry results looking at endovascular thrombectomy (EVT) outcomes in patients with medium vessel occlusion (MeVO) strokes. Data was collected from patients living in Calgary who had undergone EVT between January 2015 and December 2020 and imaging data was analyzed with a two-physician consensus. Around 140 patients were found to have a MeVO, compared to 524 large vessel occlusion (LVO) cases. No significant differences were found between the two groups at baseline, but LVO patients were slightly older than MeVO patients and had a higher percentage of poor collateral circulation. Nearly 85% of patients with MeVO achieved successful reperfusion (mevoTICI(≥2b/3)). Furthermore, there was no significant difference between the predicted home-times of MeVO and LVO patients after covariates adjustment. Factors predicting lower 90-day-home-time in MeVOs were diabetes mellitus, hypertension, and atrial fibrillation. This interview took place at the World Stroke Congress 2022 in Singapore.
