CT scanning in acute stroke patients (at home or Community Hospital) (Guidelines)


CT scanning MUST be performed within 12 hours of admission.

A CT scan is used to distinguish between ischaemic and haemorrhagic stroke. Making this distinction is important to enable appropriate secondary prevention to be used.

Acute Treatment of Ischaemic Stroke Guideline

Suitability for Secondary Prevention

Typically suitable where a confident clinical diagnosis of stroke has been made; AND
• A further vascular event would have important clinical consequences; AND
• Patients could tolerate, or co-operate with, antiplatelet or anticoagulant and other drug treatment; OR
• Has suffered a carotid distribution TIA or stroke with good recovery and is otherwise fit for carotid surgery – Rapid outpatient referral for assessment for carotid surgery is required;
• There is no upper age limit for secondary prevention, although age will influence assessment for carotid surgery;
• Further details are provided in Protocol for Secondary Prevention.
