Endovascular clot retrieval in acute stroke with large ischaemic core is not always associated with poor outcomes

Abstract

Background: The benefits of endovascular clot retrieval (ECR) for anterior circulation stroke with large ischaemic cores remain uncertain. In spite of recent pooled analysis of randomised controlled studies, conclusions regarding the fate of large ischaemic cores cannot be reached given the small number of included patients. Aim: To evaluate outcomes of ECR in acute stroke with large ischaemic core. Methods: This was a single centre retrospective study of patients treated with ECR in the period 2012–2017. The inclusion criteria were anterior circulation stroke with symptom onset less than 6 h, baseline computed tomography perfusion and a 90-day clinical follow up defined by the modified Rank..
