What Causes External Carotid Stenoses
Anomalies: these are abnormal structure or location or distribution of vessels seen in a patient. They are usually caused by having the wrong parents or by bad luck ...Read more
Can past vad - vertebral arterty dissection cause stenosis or a bruit in the carotid artery? Or any other stress to local arteries? What is the path?
Not usually: A bad trauma can cause dissection of vertebral and carotid arteries at the same time but rare. Carotid bruit can indicate a stenosis which is usually atherosclerosis. Fibromuscular dysplasia can cause narrowing. Fmd is usually in women. Fmd can affect the vertebral arteries and the carotid arteries. Fmd can cause dissection in vertebral and carotid arteries. ...Read moreSee 1 more doctor answer
Usually none: 0.5-2% of people have an anomalous right subclavian artery. It is rarely symptomatic, but in some people can cause discomfort with swallowing. ...Read more
Neck Vein Narrowing: If you are referring to pathological narrowing, it can be the result of previous clots damaging the vein, prior catheter placement in the neck vein damaging the vein as the result of scar tissue, or because of a prior phlebitis. Non-pathological visible "collapse" of the neck veins seen externally on the skin can be caused by dehydration or certain positions (veins collapse when lying down). ...Read moreSee 1 more doctor answer
2 things: Carotid artery stenosis means narrowing of the artery. Stroke is death or damage to brain due to circulatory issues. Many strokes (approx 1/3rd) are due to carotid artery disease. Although frequently connected, they are not the same. Many strokes occur without carotid stenosis. Many carotids are completely occluded (slowly) without resultant strokes. ...Read moreSee 3 more doctor answers
Atherosclerosis: The atherosclerotic plaque builds up at the bifurcation="branch point of the common carotid into external( face) and internal(brain) components. It may remain asymptomatic or may cause TIA or stroke. Commonly a significant narrowing is 80-99% there is a large medical scientific literature on this subject. ...Read moreSee 2 more doctor answers
Several: There are a number of risk factors that lead to plaque in the coronary arteries which is the reason for the blockage. Some of these are smoking, high blood pressure, unhealthy diet, an abnormally high cholesterol, lack of exercise, and obesity. There are also hereditary factors. ...Read moreSee 2 more doctor answers
Depends on degree: An mra can show a area of mild to severe narrowing. Usually this means that there is focal atherosclerosis of the vessel. The consequence of the narrowing depends on how narrow the vessel is, where the vessel is, and if there are alternative routes for blood to use to reach the area of the brain affected by the narrowed blood vessel. ...Read more
Artery blockage: Carotid artery stenosis means that the carotid arteries have blockage, usually in the form of atherosclerosis. This can cause stroke. The more severe the blockage, the greater the risk 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 stroke risk. ...Read moreSee 3 more doctor answers
Variable significanc: It depends on how large the fistulas are. A small coronary fistula can be without major effect. However, I have seen large coronary fistulas that require surgical or catheter repair. I suppose "bilateral" means both left and right coronary arteries have connections to either a coronary vein / atrium or other venous structure. ...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
Chest wall: The ima [internal thoracic artery or internal mammary artery] branches supply the chest wall structures including the ribs, muscles, breasts continueing and perforating superfically to supply the abdominal wall structures as the superior epigastric artery. ...Read moreSee 1 more doctor answer
Pain in Carotids: Inflammation in the carotid arteries may cause pain. More importantly, it is critical that you see a vascular surgeon to have your carotid arteries evaluated. You will need a carotid duplex to assess the amount of stenosis in the arteries, if any. Carotid artery blockage is one of the leading causes of strokes. Have this evaluated today. ...Read moreSee 1 more doctor answer

Arterioclerosis: Arteriosclerosis or plaque buildup in the wall of the coronary arteries will narrow the lumen to the point where there is flow restriction, then clot formation. The plaque may rupture, allowing a flap-like effect, blocking the lumen, resulting in clot formation. Trauma may cause a separation of the layers of the wall, and this dissection results in clot formation. ...Read moreSee 1 more doctor answer
