Carotid artery pain, generally common clinical causes are mainly the following: First, the formation of carotid artery aneurysm, mostly seen in the carotid artery intima damaged artery wall thinning, carotid artery internal pressure is significantly increased, the weakness of the wall of the artery can be expanded outward, forming aneurysm-like changes and cause patients involved in pain. At this time, the patient can have the size and location of the aneurysm clarified by arterial ultrasound examination, and it is recommended that the patient undergoes surgery to remove the diseased artery or interventional treatment as soon as possible to avoid rupture of the aneurysm and fatal hemorrhage. Second, severe stenosis of the carotid artery can cause local blood flow reduction, which can lead to ischemia and hypoxia induced pain symptoms. Patients can improve the severity of arterial stenosis through arteriogram or ultrasound examination, and if necessary, surgical stent implantation to expand the carotid artery vessels and improve local pain symptoms.
