Apr 08, 2010 the carotid bulb, a wider portion of the artery than that distally, a given stenosis would be more severe using the ECST method as compared to that of NASCET. ECST methodology requires an assumption of the true lumen, which increases the risk of inter-rater variability.

Carotid Stenosis (carotid artery disease)

coronary artery disease, a family history of carotid stenosis, and advanced age. Less commonly, carotid aneurysm and fibromuscular dysplasia can cause carotid stenosis. People who have heart disease have an increased risk of developing carotid stenosis. Typically, the carotid arteries become diseased a few years later than the coronary arteries.


Stenosis means narrowing. Carotid artery stenosis means the main artery supplying blood to your brain is narrowing. The narrowing of the carotid artery is caused by a buildup of plaque. This can be dangerous and cause a stroke. To diagnose carotid artery stenosis, your doctor will order an imaging test to help determine how severe the narrowing
