Left Carotid Artery Blockage
Carotid blockage: If asymptomatic with use of proper medical therapy a moderate carotid blockage is fairly low risk. Many vascular surgeons would favor no intervention in this situation. If symptomatic, would recommend repair of this. Options include stenting or open surgery, carotid endarterectomy. Best data suggests that stenting over age 65 -70 has higher risk of stroke than endarterectomy. ...Read moreSee 2 more doctor answers

Visiting an eye doctor may help make this diagnosis. ...Read moreSee 2 more doctor answers

For those carotid arteries without a blockage, some physicians measure the intima (the inner-most lining of the artery) and derive a value called the imt, or intimal-medial thickness. It's supposed to help us determine severity of atherosclerosis, but this is somewhat controversial. ...Read more
How likely would it be that both Carotid arteries <50% Occluded will progress on medication
to a higher percent blockage over a year in a female 75+?
Carotid blockage.: It's not the presence or absence of the medication that matters. It's the efficacy of the medication that matters. How well are BP, blood sugar, cholesterol and weight controlled? Are we smoking cigarettes? Blockage will progress if risk factors for progression are not adequately controlled. ...Read more
Excellent: Ultrasound duplex imaging of the cervical carotid arteries is very good at determining significant arterial narrowing. Changes in the flow patterns of the carotid arteries can also suggest disease in the internal carotid arteries further on in at the skull base even though the arteries themselves cannot be seen at that level. ...Read more
