Abstract
IntroductionThrombectomy has become the standard treatment for acute ischemic stroke (AIS) caused by large vessel occlusions (LVOs). The Aperio Hybrid (Acandis, Pforzheim, Germany) is a new stent retriever designed to enhance the effectiveness of this treatment. However, this new stent has not yet been compared to other thrombectomy devices in a clinical setting. The aim of this study was to compare the Aperio Hybrid® with the Solitaire™ FR/X (Medtronic, Minneapolis, USA) during thrombectomy in patients with AIS due to anterior circulation LVO.Materials and methodsWe analyzed data from a multicenter registry of thrombectomy for anterior circulation LVO. Patients with carotid/M1 or proximal M2 occlusions who underwent thrombectomy with either the Aperio Hybrid® or Solitaire™ FR/X® were compared using propensity-score matching (PSM). The primary outcome was the recanalization rate, measured by the Treatment in Cerebral Ischemia (TICI) score of 2b-3, while the secondary outcome was the rate of symptomatic intracranial hemorrhage (sICH).ResultsAmong 455 patients treated, after PSM, 258 patients (129 per group) were analyzed. The adjusted recanalization rates (TICI 2b-3) for the Aperio Hybrid and Solitaire FR/X were 79.8% and 75.9%, respectively (p = .08), while the adjusted sICH rates were 6.9% and 6.2%, respectively (p = .80).ConclusionsIn this observational study on thrombectomy for AIS, the Aperio Hybrid and Solitaire FR/X demonstrated similar rates of recanalization and symptomatic intracranial hemorrhage. However, due to significant selection bias, these results should be interpreted with caution.
