Key result
Doppler ultrasound correctly classifies 78% of diseased vessels compared to carotid and arch aortography.
Why the study?
Does Doppler ultrasound accurately detect carotid disease compared to carotid and arch aortography in patients with transient cerebral ischaemic attacks or small strokes?
Observational
Does Doppler ultrasound accurately detect carotid disease compared to carotid and arch aortography in patients with transient cerebral ischaemic attacks or small strokes?
Doppler ultrasound offers a safe and accurate screening procedure for detecting carotid disease in patients with transient cerebral ischaemia or small strokes.
Supports Doppler screening accuracy in TIA; leaves open prospective validation before routine use.
Results are presented from a two year prospective study using a Doppler ultrasound technique for the detection of carotid disease. The patients studied presented with transient cerebral ischaemic attacks or small strokes in the carotid territory. No other form of patient selection was used. Results were compared with those from carotid and arch aortography. 86% of normal vessels and 78% of diseases vessels were correctly classified. It is concluded that this technique offers a safe and accurate screening procedure for the management of patients presenting with transient cerebral ischaemia or small strokes.

Lakeman et al. (1981) conducted an observational in Transient cerebral ischaemic attacks or small strokes in the carotid territory. Doppler ultrasound vs. Carotid and arch aortography was evaluated on Correct classification of normal and diseased vessels. Doppler ultrasound correctly classified 86% of normal vessels and 78% of diseased vessels compared to carotid and arch aortography.
