Could you lose function to certain parts of the body if nerves around a internal or external carotid artery were cut?

Could you lose function to certain parts of the body if nerves around a internal or external carotid artery were cut?

Yes: There are two main nerves that are in the area of the carotid artery. Above the bifurcation of the Internal and external carotid is the hypglossal which controls the toungue. If cut, the toungue will deviate to the side of the injury. The other main nerve is the vagus. It is located between the common carotid and int jugular, if cut would be disasterous ...Read more

Artery (Definition)

Arteries are a type of blood vessels. We can divide blood vessels into 2 categories. Arteries are high pressure vessels which deliver (red) oxygen + blood out into the body. Veins on the other hand or low pressure vessels which return (dark) oxygent - blood from the body ...Read more

If your internal carotid arteries are normal wouldnt the external ones be normal as well?

If your internal carotid arteries are normal wouldnt the external ones be normal as well?

No certainty & be: aware that only the opening is usually evaluated by ultrasound or angiography. While relevant for blood flow (at the moment), atherosclerosis is in the walls, does not produce narrowing & plaque ruptures leading to clot promoting debris shedding into the blood stream & clots are what creates strokes, not narrowing.

I have less than 50% stenosis of the bilateral internal carotid arteries by nascet criteria, should I be concerned?

I have less than 50% stenosis of the bilateral internal carotid arteries by nascet criteria, should I be concerned?

generally no: This is mild/moderate blockage and rarely associated with symptoms. Treatment is usually Aspirin and a statin.Do not smoke! follow up with carotid ultrasound every few years. ...Read more

Mild diffuse atherosclerotic plaques are seen w in internal carotid arteries. No hemodynamically significant carotid stenosis per ratio criteria?

Mild diffuse atherosclerotic plaques are seen w in internal carotid arteries. No hemodynamically significant carotid stenosis per ratio criteria?

Focus on risks: Mild and diffuse atherosclerosis at age 46 implies a need to focus on risk factor modification to achieve primary prevention of stroke and enhance vascular protection. Optimize lipids, avoid smoking, cand control sugar and BP issues. ...Read more

Can you you explain peak systolic velocity in right internal carotid artery 61.9 and 80.7 in left internal carotid?

Can you you explain peak systolic velocity in right internal carotid artery 61.9 and 80.7 in left internal carotid?

Sounds normal: These velocities sound normal. As your carotids narrow, the velocity of blood increases. Sort of like when you put your thumb over the end of a hose. The water moves faster and goes farther. In many labs, the cutoff is 125cm/s. Below this, there may be some narrowing, stenosis, but it is not significant. Discuss the results with your doctor. ...Read more

What does it mean when you have 1-15% stenosis of right and left internal carotid artery and that clinical correlation recommended?

What does it mean when you have 1-15% stenosis of right and left internal carotid artery  and that clinical correlation recommended?

Mild narrowing: The cutoff for a signicant or abnormal is 50% narrowing or greater. Minor narrowing < 30% is considered normal. Clinical correlation means to ask your doctor what the test means for you as an individual. ...Read more

What could cause peak systolic velocity of right internal carotid artery to be elevated to 130cm/s but no elevation in left ica & no stenosis found?

Peak velocity: Sometimes what is being recorded is not the velocity in the internal carotid but an adjacent artery such as external carotid . This could also be related to high flow situations or other technical factors. ...Read more

Carotid Arteries (Definition)

The carotid arteries start in the chest and progress up the sides of the neck. About mid neck they split and one branch supplies blood to the face the, the other continues without branches into the skull and supplies ...Read more
