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 defined as blood vessels which carry blood away from the heart (to either the body or lungs). Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more

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

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. Study: http://goo.gl/aRhOU2, the image & my answers on healthtap for understanding. ...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

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

Was originally told I had a dissection of my internal carotid artery.... Now being told it is a pseudo aneurism..... What exactly is the difference?

Was originally told I had a dissection of my internal carotid artery.... Now being told it is a pseudo aneurism..... What exactly is the difference?

See below: An pseudoaneurysm is when there is a breach in the blood vessel (usually due to injury), but the bleeding gets trapped by the surrounding tissue forming a hematoma. A dissection is actual tearing of the layers of the carotid artery - in this case. In general terms, dissection tends to be more of a surgical issue. In both cases, treatment depends on the size, etiology of the condition. ...Read more

Internal carotid artery dissection and exercise...My dissection has mostly healed (2mm aneurysm remains) over the last 20 months. What kind of exercise can I do and at what intensity?

Internal carotid artery dissection and exercise...My dissection has mostly healed (2mm aneurysm remains) over the last 20 months.  What kind of exercise can I do and at what intensity?

Ask UR cardiologist: Whoever is following you medically needs to be involved in this discussion, as their recommendations is what you'll need to follow closely. Give your doctor a call, and she what s/he says. You don't want to aggrevate the remaining 2 mm aneursym present. This is a great question, and glad you are exercising carefully! ...Read more

I have pulsatile tinnitus in left ear, and significant tortuosity of the left upper internal carotid artery below the skull base. Is there a cure?

I have pulsatile tinnitus in left ear, and significant tortuosity of the left upper internal carotid artery below the skull base.  Is there a cure?

Anatomical variant : These findings are anatomical variants and can not be really treated. The tortuous internal carotid artery is not the reason for the pulsatilla timnitis. If the circle of Willis is clean - no intervention is necessary. If you are bothered by the tinnitus you could get a hearing test and find out where you hearing, you can then get tinnitis masker from your local ent ...Read more

My mri shows hypolastic right vertibal artery and mild irreularity along the bilaeral segment of internal carotid artery?

My mri shows hypolastic right vertibal artery and mild irreularity along the bilaeral segment of internal carotid artery?

Low value finding.: Why? 2 reasons: 1. Spacial resolution of MRI (even more so than CT) is very low compared to the complexity of the anatomic structures named & 2. Arteries are not being visualized, only a contrast agent within the blood inside the artery. Get & study the image data yourself; compare with Netter anatomy illustrations. Irregularity is c/w artery Ds. Good quality echo of carotid walls far better. ...Read more

Left internal carotid artery is difficult to evalution in doppler study. What will be impact on health and what is cure for this.
?

Well, ....: Depending on why you even had the doppler done will answer the question. That simply means anatomically, they may not have seen the carotid well on the study. If you and your Doctor have concerns about the patency of the Artery, then a dye study could be ordered to confirm this since the doppler was inadequate. ...Read more

What does it mean when an mra shows the intracranial right internal carotid artery is narrowed ?

What does it mean when an mra shows the intracranial right internal carotid artery is narrowed 
?

Depends on degree: An mra can show a area of mild to severe narrowing. Usually this means that there is focal atherosclerosis of the vessel.

The consequence of the narrowing depends on how narrow the vessel is, where the vessel is, and if there are alternative routes for blood to use to reach the area of the brain affected by the narrowed blood vessel. ...Read more

Bilateral high flow in common carotid artery and internal carotid artery with normal end diastolic velocity and no stenosis. Is this normal?

How high is high?: Increased flow without stenosis can happen if the cardiac output is very high or there is tortuosity if the arteries Generally don't worry until systolic velocity is over 200 cm/sec and even then it is probably ok with normal diastolic velocity why did you get the test? IF you are asymptomtic I would not worry too much ...Read more

MRI vertebrobasilar hypoplasia right side theres robust flow void anastomosing the basilar artery w cavernous portion of internal carotid artery/mean?

Normal variant: The arteries at the base of the brain can course in several different patterns but ultimately get the job done, that is, supply brain tissue. Your pattern is like your fingerprint.
Some more unusual patterns have an increased association with aneurysms, but this would have likely been described if present and vertebro basilar hypoplasia, as in the picture, is pretty common. ...Read more

Sharp throbbing pains each side of throat in front in internal carotid artery region. Ears feel clogged/fuzzy. Right LN swollen. Worse with exertion?

An infection: It sounds like you have a viral or bacterial infection. Get a throat culture to make sure you do not have strep throat which is usually the only reason that you may need antibiotics for this. In the meantime, tylenol (acetaminophen) and/or motrin, fluids, chloraseptic or cepastat and rest. If you get much worse, severe headaches, throat closes, or shortness of breath, or anything else scary, then go to the ER ...Read more

Yes : For the noise in your ear they make noise damper devices. There is no medication in surgery would do a lot more harm than good as long as the blood flows normal in your Carotid artery. As far as mitral valve prolapse and you do have to have more information from your doctor cardiologist regarding treatment in most prolapse and without Regurgitation mitral valve does not require any treatment ...Read more

Where can i get the most accurate visual look at the aorta and how it also ascend into the carotid arteries?
