Based on the NASCET (The North American Symptomatic Carotid Endarterectomy Trial) criteria, the degree of carotid stenosis is defined as: [22] percent stenosis = ( 1 − ( minimum diameter within stenosis) / ( poststenotic diameter ) ) × 100%. Calculators have been developed to facilitate grading of carotid stenosis per NASCET criteria. [23]
Carotid endarterectomy is used to reduce the risk of strokes caused by carotid artery stenosis over time. Carotid stenosis can either have symptoms (i.e., be symptomatic), or be found by a doctor in the absence of symptoms (asymptomatic) - and the risk-reduction from endarterectomy is greater for symptomatic than asymptomatic patients.
Carotid artery stenting is an endovascular procedure where a stent is deployed within the lumen of the carotid artery to treat narrowing of the carotid artery and decrease the risk of stroke. It is used to treat narrowing of the carotid artery in high-risk patients, when carotid endarterectomy is considered too risky.
Severe stenosis constitutes a diameter loss of 2/3 or more—a greater-than-90% loss of cross-sectional area. [5] To more accurately determine the severity of stenosis, interventional cardiologists may also employ intravascular ultrasound , which can determine the severity and provide information on the composition of the atheromatous plaque.
Presence of a carotid pulse has been estimated to indicate a systolic blood pressure of more than 40 mmHg, as given by the 50% percentile. [8] Carotidynia is a syndrome marked by soreness of the carotid artery near the bifurcation. Carotid stenosis may occur in patients with atherosclerosis.
Information pertaining to the diagnosis, indications, procedural details and outcomes of carotid artery stenting are reviewed for quality control of individual stentors at over 100 centers across the US. Lessons learned from C2R have informed the best criteria that define high standards for carotid stenting. [25]
