Recommendations for Management of Patients with Carotid Stenosis
Catheter angiography is the criterion standard for defining the degree of stenosis and the morphologic features of the offending plaque. Antithrombotic Therapy in Carotid Artery Stenosis: Cessation of embolic signals after antithrombotic prevention is related to reduced risk of recurrent arterioembolic transient ischaemic attack and stroke. Evaluation of transient ischemic attack in an emergency department observation unit.
All types of ischemic stroke were included, with an overrepresentation of patients with small-vessel disease, a group in whom the underlying process is not embolism from atherosclerotic plaque and who have a lower risk of early recurrent stroke.
Methods The authors performed a retrospective, institutional review board—approved review of consecutive patients who underwent CEA. View inline View popup. Aspirin, the most commonly used antiplatelet agent, inhibits the enzyme cyclooxygenase, reducing production of thromboxane A2, a stimulator of platelet aggregation. Duplex ultrasound and magnetic resonance angiography compared with digital subtraction angiography in carotid artery stenosis: This entry was posted on Friday, September 20th, at Most emboli result from activation of platelets on the plaque surface, and less frequently cholesterol particles.

Message Body Your Name thought you would like to see the Circulation web site. To determine such hypothesis, we need to directly compare medical therapy, especially antiplatelet, to surgery. A 1-hour TCD recording was performed on eligible patients. Related Articles for " ".
Regarding the combination of aspirin and clopidogrel, there is some evidence that it is significantly better than aspirin alone at preventing embolization from recently symptomatic carotid stenosis. Previous small single-center studies 20—22 have used this technique, and a recent large single-center study in patients undergoing carotid endarterectomy in the immediate postoperative period also demonstrated that the combination of clopidogrel and aspirin was more effective than aspirin alone in reducing MES.
For the above reasons, aspirin should be continued before and after surgery. Consensus on microembolus detection by TCD. The primary analysis was performed with the use of offline central analysis of MES recordings. There are some questions that need to be answered before relying on these results in recommending CAS to patients who are at high risk for CEA [ 73 ].
