Answer:
The answer is Carotid Murmur.
Explanation:
The carotid murmur is the presence of an abnormal noise that is heard with the stethoscope placed on the lateral wall of the patient's neck, almost always due to a stenosis of the carotid artery; that is to say, there is a narrowing in the lumen of the vessel, decreasing the amount of blood that goes to the face, head and brain. This narrowness of the vessel is presented by the accumulation of plaques within the arteries (arteriosclerosis).
