Calcification Of Carotid Arteries
None: Calcification of any artery, by itself, does not warrant any type of intervention or follow up. If that calcification is associated with a stenosis ("narrowing") of the artery, then that may require follow up and/or an operation. The carotid arteries are very often calcified and if associated with a high grade stenosis, may portend a higher risk of stroke. Discuss with a vascular surgeon. ...Read more
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
Exceedingly unlikely: The chances of this happening are extremely remote. Having said that we are always extremely cautious in examining patients with carotid artery atherosclerosis. I have personally witnessed at least one patient getting a stroke after a carotid artery examination--fortunately he recovered. So it is theoretically possible to get a stroke large enough to cause death, but the odds are extremely small. ...Read more

Very: As long as the portable ultrasound screening program is icavl accredited, the results will be 90%-98% accurate. Ultrasounds are operator dependent, that is why it is important that the ultrasound lab follow standard protocols to optimize results. Icavl is an acronym for... Intersocietal commission for the accreditation of vascular laboratories. ...Read moreSee 2 more doctor answers
See vascular surgeon:
I suspect he means that the carotid arteries have partial blockage, usually in the form of atherosclerosis.
In the absence of neurological symptoms, most cases can be handled with medicine and close periodic follow up by a vascular surgeon. However, if the blockage is more than 80%, surgery will reduce the risk of stroke. In very special instances, carotid angioplasty and stent may be an option. ...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
Can tias over time be caused by temporary or partial occlusion of vertebral or carotid arteries and cause foci or lesions?
Yes: Tia's are short-lived, about 20-30- minutes and usually fully reverse. If not, it is a stroke with tissue damage, and then can be seen on an mri. The event heralds risk, and preventative treatment with an antiplatelet drug should be started. An embolism from say the heart or aorta, may need anti-coagulation. The greatest future risk of TIA is a stroke within one year. ...Read more
When u r physically active does ur aorta and carotid arteries constrict or expand? Symp nersyst makes arteries constrict right? If u r stressed?
I have been pressing my carotid arteries every day for a year now to check my pulse. Sometimes just light but also hard. What's the effects? Clots?
Not too hard!: If you compress your carotid too vigorously, you can initiate a reflex that slows your heart and, in the extreme, could even cause you to pass out. (unlikely). If you press hard and long, you can interrupt circulation to that side (hemisphere) of your brain and cause damage. If you must check your carotid, press gently and for no more than 15 seconds. ...Read more
Carotic Arteries: The human carotid arteries supply the head and the neck with oxygenated blood. The left common carotid artery originates from the aorta and the right common carotid originates from the brachiocephalic artery which originates from the aorta. The carotic artery divides in the neck to form the internal and external carotic arteries. ...Read moreSee 1 more doctor answer
