The gray zones, case by case

Fictional spoken referrals in the 3am voice — the cases where the guidelines go quiet.

Synthetic cases. These are fictional teaching vignettes, model-generated for testing clinical-reasoning systems. No real patients are described on these pages.

What this is

A bank of constructed referrals, written the way a referral actually arrives: spoken, compressed, incomplete, at three in the morning.

They are fiction — model-generated vignettes built for testing clinical-reasoning systems — and they are realistic precisely because the situations they describe are the ones every stroke physician recognises. No patient is described here; no patient material was used.

Why they exist

Gray zones only show themselves in concrete cases. A guideline can tell you that the evidence for thrombectomy in baseline-dependent patients is thin; it takes a 91-year-old with a dense M1 occlusion and a family in the relatives' room to show you what "thin" costs. The four cases below were chosen because each one walks straight into a territory where the randomised envelopes end — the same territories our in-press review of EVT contraindications works through.

The four cases

Pages are numbered by bank ID; future cases join mechanically.

The invitation

Send us the anonymised cases where the guidelines went quiet.

Break the demo — send a case

For stroke physicians and vascular neurologists only. This is not a route for personal medical questions; if you are a patient or a relative, do not use this address. The demo does not run anonymously, and it is not a clinical service. Every case is reviewed and approved by the administrator before it runs; responses may take several days. Never use this for a live clinical decision — for acute stroke, follow your local pathway.

Your case must contain no images and no patient-identifying data, and it must be retrospective — not an active patient awaiting a decision. A case may appear on this site anonymously, as a constructed teaching case; you are named only if you ask to be.
