Internal And External Carotid Arteries
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
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
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.

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?
Does a 0.5 x 0.5 x 0.5 CM well defined saccular outpouching in the medial aspect of the supraclinoidsegment of right internal carotid artery dangerous?
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?
