Detailed explanation-1: -A carotid duplex ultrasound is performed to evaluate symptoms including dizziness, loss of memory, stroke, loss of musclecontrol and other symptoms that might result from narrowing or blockage of the vessels (carotid arteries) on either side of your neck. A carotid ultrasound can also be used to screen for stroke risk.
Detailed explanation-2: -A carotid artery duplex scan is a type of vascular ultrasound study done to assess occlusion (blockage) or stenosis (narrowing) of the carotid arteries of the neck and/or the branches of the carotid artery. A carotid artery duplex scan is a noninvasive (the skin is not pierced) procedure.
Detailed explanation-3: -Carotid duplex ultrasound is an easy non-invasive screening test that can be used to identify patients with significant ICA stenosis; it has a moderate sensitivity and low specificity in identifying patients who are at risk of developing stroke after cardiac surgery [5, 9, 12, 15, 16, 18, 20].
