Despite the therapeutic nihilism of the past, the advent of thrombolysis has changed the way stroke treatment is approached. Acute ischemic stroke is a challenging and heterogeneous disease, and treatment must be based on an understanding of the underlying pathophysiology of ischemia. Interventions are designed to improve neuronal salvage and outcome. The underlying tenets of stroke therapy focus on the brain parenchyma, arterial flow (pipes), perfusion, the ischemic milieu or penumbra, and prevention of complications. This article focuses on the practical issues of ischemic stroke care with a brief review of supporting literature.
