Doctor insights on:
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 moreSee 1 more doctor answer
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
What does artherosclerotic calcifacations at the bifurcation and into the right common iliac artery? Is it something to worry about?
PAD/PVD; yes: Atherosclerotic calcification refers to arteries plugged w/calcified cholesterol plaques. Because this occurred in arteries to legs, it means you have peripheral artery/vascular disease. This also means you probably have some blockage in your heart (coronary arteries), too. Possibly even your carotids (in your neck). So yes need to be concerned about this to lower risk for heart attack, stroke etc. ...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
Very Serious: Generally speaking common iliac artery aneurysm are recommended for repair at around 3-3.5 cm, but these are often found in association with other types of aneurysms, such as aortic aneurysms or lower extremity arterial aneurysms. Only a vascular surgeon can take your entire history into account and recommend surgery or observation for now. The fact that it is saccular may be significant. ...Read moreSee 2 more doctor answers
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?
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 moreSee 1 more doctor answer
Will compressing(blocking) both the left and right common carotid arteries for a sufficient period of time lead to complete brain death?
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 .
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 moreSee 1 more doctor answer
