Although these are low risks they make angiography undesirable as a screening technique. Therefore, carotid doppler ultrasound, MRA, and spiral CT have been developed primarily as screening techniques for carotid vascular disease. Carotid Doppler Ultrasound Carotid Doppler Ultrasound is widely used as a screening technique for evaluating carotid vascular disease. The velocity of the flow of blood through the carotid artery is used to determine the degrees of stenosis. Magnetic Resonance Angiography MRA is a noninvasive modality that uses various MRI techniques to produce angiographic images.
Treatment generally is a matter of choice of carotid endarterectomy versus medical treatment.
Other options include balloon angioplasty. Medical management Antiplatelet Therapy Aspirin - prevents platelet aggregation decreasing the formation of clots. Generally a dose of 325mg orally per day is used. In addition, the drug is more expensive than aspirin.
