Factors influencing the need for emergent conversion to general anesthesia during mechanical thrombectomy in acute anterior circulation stroke – A retrospective observational study

•Emergency conversion from CS to GA during the procedure can occur, but its predictors and impact on clinical outcomes are not fully understood.•Atrial fibrillation and prolonged duration of procedure were identified as the independent predictors of emergency conversion to GA.•Emergency conversion to GA did not have any impact on the good functional outcome compared to CS at discharge or the rate of successful recanalization.
