Abstract

Abstract: This chapter addresses the neurosurgical management of stroke due to acute middle cerebral artery occlusion. Large vessel occlusion is a common mechanism of acute ischemic stroke. Mechanical thrombectomy has emerged as an important procedure that drastically improves outcomes in this disease. This chapter discusses the diagnosis and treatment of acute ischemic stroke from large vessel occlusion, including the rapid radiographic evaluation with CT, CTA, MRI, and perfusion imaging. The scoring of the stroke using scales such as the ASPECTS score and their use in decision-making is reviewed. The chapter then discusses treatment with both chemical thrombolysis and mechanical thrombectomy, including the technical aspects of the procedure.
