ECASS criteria
Pronunciation: EE-kas
Also written as: ECASS — European Cooperative Acute Stroke Study
European Cooperative Acute Stroke Study criteria used to classify hemorrhagic transformation types in stroke imaging interpretation.
Full Definition
ECASS (European Cooperative Acute Stroke Study) criteria provide a standardized classification system for hemorrhagic transformation following acute ischemic stroke, ranging from hemorrhagic infarction (HI-1, HI-2) to parenchymal hematoma (PH-1, PH-2). These criteria are essential for editors working with stroke imaging reports, as they determine treatment decisions and prognosis. The classification system is based on CT or MRI findings and helps distinguish between different types of post-stroke bleeding. Proper application of ECASS criteria terminology ensures consistent communication between radiologists, neurologists, and stroke teams. Editors must be familiar with the specific numbering system and abbreviations used in this classification.
Usage
Usage note: Always capitalize the acronym; spell out on first use in formal documents.
