Description
Summary:	Background Assessment of the impact of the thrombectomy learning curve on clinical outcomes is essential for developing healthcare system protocols. Aims The aim of this study was to assess the effect of thrombectomy case volume on procedural and clinical outcomes in a Brazilian registry. Methods A total of 645 patients with acute ischemic stroke treated by thrombectomy were included in the analysis. Patients were divided into two groups regarding the period of treatment: the early period group and the late period group. Results In the adjusted analysis, treatment in the late period was an independent predictor of recanalization (odds ratio 1.91, 95% CI 1.28–2.86) and excellent neurologic outcomes at three months (odds ratio 1.77, 95% CI 1.04–3.01). Treatment in the late period had no significant association with mortality (odds ratio 0.88, 95% CI 0.55–1.41). Conclusions An increase in thrombectomy case volume for the treatment of AIS over time was an independent predictor of recanalization and excellent neurologic outcome.
