In this post I link to and excerpt from Toast classification in acute ischemic stroke from Radiopaedia, accessed 3/14/2021.
Here are excerpts:
The TOAST (trial of ORG 10172 in acute stroke treatment) classification denotes five sub types of ischemic stroke.
- large-artery atherosclerosis (embolus / thrombosis)*
- cardioembolism (high-risk / medium-risk)*
- small-vessel occlusion (lacune)*
- stroke of other determined etiology *
- stroke of undetermined etiology
It is thought to carry good inter observer agreement and predict prognosis, outcome, and management
