Abstract
Background: We aim to assess the association between procedural time and outcomes in patients in unsuccessful mechanical thrombectomy (MT) for anterior circulation acute stroke.Methods: We conducted a cohort study on prospectively collected data from patients with M1 and/or M2 segment of middle cerebral artery occlusion with a thrombolysis in cerebral infarction 0–1 at the end of procedure. Primary outcome was 90-day poor outcome. Secondary outcomes were early neurological deterioration (END), symptomatic intracranial hemorrhage (sICH) according to ECASS II and sICH according to SITS-MOST.Results: Among 852 patients, after comparing characteristics of favourable and poor outcome groups, logistic regression analysis showed age (OR: 1.04; 95%CI: 1.02–1.05; p < 0.001), previous TIA/stroke (OR: 0.23; 95%CI: 0.12–0.74; p = 0.009), M1 occlusion (OR: 1.69; 95%CI: 1.13–2.50; p = 0.01), baseline NIHSS (OR: 1.01; 95%CI: 1.06–1.13; p < 0.001) and procedural time (OR:1.00; 95% CI: 1.00–1.01; p = 0.003) as independent predictors poor outcome at 90 days. Concerning secondary outcomes, logistic regression analysis showed NIHSS (OR:0.96; 95%CI: 0.93–0.99; p = 0.008), general anaesthesia (OR:2.59; 95%CI: 1.52–4.40; p < 0.001), procedural time (OR: 1.00; 95% CI: 1.00–1.01; p = 0.002) and intraprocedural complications (OR: 1.89; 95%CI: 1.02–3.52; p = 0.04) as independent predictors of END. Bridging therapy (OR:2.93; 95%CI: 1.21–7.09; p = 0.017) was associated with sICH per SITS-MOST criteria whereas M1 occlusion (OR: 0.35; 95%CI: 0.18–0.69; p = 0.002), bridging therapy (OR: 2.02; 95%CI: 1.07–3.82; p = 0.03) and intraprocedural complications (OR: 5.55; 95%CI: 2.72–11.31; p < 0.001) were independently associated with sICH per ECASS II criteria. No significant association was found between the number of MT attempts and analyzed outcomes.Conclusions: Regardless of the number of MT attempts and intraprocedural complications, procedural time was associated with poor outcome and END. We suggest a deeper consideration of procedural time when treating anterior circulation occlusions refractory to MT.
