What is the meaning of "mid common carotid artery?"

What is the meaning of "mid common carotid artery?"

Anatomy: Simply put it's the middle portion of the common carotid artery which originates generally from the aortic arch within the chest and runs in your neck on the way to the brain. The pulse most people feel in their neck is the distal common carotid artery, the last most portion of this vessel, before it splits. The mid portion cannot typically be felt because it would be behind the collar bone. ...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

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

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

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

Carotid artery stenosis is how common at which age groups?

Above 50 : There is different numbers depending on age ( more common above 50), sex ( more common in males), presence of symptoms and severity of stenosis . Generally incidence of asymptomatic more than 50% stenosis in people above 50 years of age is around 6-11% in men and 5-7% in women. ...Read more

How common is a carotid artery dissection?

Uncommon: A dissection is a separation of the inner layer of an artery from the outer layer. The risk aside from direct obstruction is that the internal blood pressure can enter this new pocket and rapidly tear open more of the lining, shutting down the artery or even causing a leak - both of these events are deadly. Any major arteries can be affected; the carotid is less common than the aorta. ...Read more

How common is it to see carotid arteries pulsing through your neck?

How common is it to see carotid arteries pulsing through your neck?

It can be.: If you are able to see your carotid artery pulse in your neck, you're likely quite thin. Rarely a prominent, pulsatile carotid artery in the neck is a sign of a carotid artery aneurysm, an abnormal englargement of the artery which can lead to problems such as stroke or rupture/bleeding. This would be rare in a 43 year old without a history of trauma. See a vascular surgeon to be sure. ...Read more

Could blocking only one of the left and right common carotid arteries lead to complete brain death?

Unlikely: The blood flow to the brain comes from anterior circulation, the carotids, and posterior, the basilar branching into the 2 vertebrals. Complete unilateral carotid thrombosis could cause a significant stroke but the collateral circulation could mitigate the damage, and preserve substantial function. ...Read more

What are symptoms differences both common carotid arteries are compressed from that when both jugular veins are compressed?

One Hurts: When you compress both carotids, you only have two tiny arteries ("vertebrals") left supplying the whole brain. Ergo, you hit the ground unconscious. If the compression isn't relieved, you die fast. The veins are more compliant, but less redundant. Compression of the jugular leaves the brain with no backup drainage. You'll get a phenomenal headache as pressure builds up, then something will pop. ...Read more

How different are symptoms when both common carotid arteries is compressed from that when both jugular veins are compressed?

How different are symptoms when both common carotid arteries is compressed from that when both jugular veins are compressed?

Ischemia or congesti: When compressing both carotid artery, the blood flow to brain will be cut down as ischemic condition as like fainting, dizzy or passing out. The both jugular vein compressing cause congestion of blood to brain may cause headache, nausea or vomiting. ...Read more

How common is a 280 degree loop of the carotid artery & is it serious? I'm also suffering severe headaches, can it be related?

Not common : Looping of the carotid artery is not common but by itself does not indicate the need for treatment. The headaches are probably unrelated and you should consult with your physician or a neurologist. If the looping or tortuosity is associated with episodes of weakness or vision loss on the same side you should see a vascular surgeon. Otherwise you should probably not worry about it. ...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
