What makes a stroke worsen during a long transfer?
Published in Frontiers in Neurology, 2024 · Summary posted 5 July 2026
In plain language
When someone has a large-vessel stroke far from a specialist centre, the core of irreversible brain damage can grow during the journey to treatment. This study looked at which clinical details and imaging features at the local hospital predict how much that damage progresses by the time the patient arrives.
Patients were compared using their initial scans and a repeat CT on arrival, and the team used established imaging criteria (DEFUSE 3) to define whether a patient still had “favourable” imaging suitable for clot retrieval.
Why it matters
Understanding who is likely to still be a good candidate for treatment after a long transfer helps stroke networks make better, faster decisions about which patients to move, and how quickly. For people who live outside major cities, those decisions can shape the difference between recovery and lasting disability.
