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

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

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?

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

Will compressing(blocking) both the left and right common carotid arteries for a sufficient period of time lead to complete brain death?

Yes.: Your brain is always active and requires a great deal of oxygen to function. Complete occlusion of both carotid arteries would compromise blood flow to most of the brain and could cause a hypoxic brain injury or death. ...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

Why compressing both left and right common carotid arteries leads to brain death when vertebral arteries(and also circle of willis) still supply .

Why compressing both left and right common carotid arteries leads to brain death when vertebral arteries(and also circle of willis) still supply .

Carotid occlusion: The vertebral arteries are not enough to sustain the entire blood brain perfusion. They contribute to the anterior circulation by means of the posterior communicating arteries. There are common anatomical variants and in some cases these arteries are not patent or existent. The situation you describe may and most likely cause a massive brain infarction with subsequent brain herniation/death. ...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

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
