Background: Recently, angioplasty and stenting of carotid arteries (CAS) have taken the place of surgery. The aim of our study is to assess the role of transcranial Doppler (TCD) monitoring during CAS to address the embolic complications during the stages of the procedure, with or without embolic cerebral protection devices. Methods: A total of 152 patients were submitted to carotid stenting. All patients were submitted to carotid arteries Duplex scanning. Results: Neurological complications are related to TCD detection of corpuscolate signals in rapid succession. Even if no reduction of the overall incidence rate of microembolic signals (MES) was observed, a decrease in the number of corpuscolate emboli were recorded when a cerebral protection was working. Conclusions: According to our study, even in selected patients on the basis of preoperative diagnostic criteria, CAS is burdened by a nonnegligible risk of subclinical embolic ischemic events detected at TCD and confirmed by diffusion-weighted magnetic resonance imaging (DW-MRI).

Stroke remains a significant contributor to morbidity and mortality in developed countries. Carotid artery stenosis is a major cause of stroke. Advances in medical therapy, surgical technique and endo...
Transfemoral carotid artery stenting (CAS) with endovascular proximal flow blockage is deemed able to reduce the cerebral embolization observed during filter-protected CAS. We evaluated clinical outco...
To compare the complication rates associated with carotid endarterectomy (CEA) versus carotid artery stenting (CAS).
Severe carotid stenosis or occlusion may cause insufficient blood flow and lead to distal artery wall collapse and extensive lumen contraction. Whether this 'adaptive narrowing' can restitute after ca...
We aimed to quantify the risk and predictors of ipsilateral ischemic stroke in patients with symptomatic carotid stenosis awaiting revascularization (carotid endarterectomy [CEA] or carotid artery ste...
Carotid revascularization for primary prevention of stroke (CREST-2) is two independent multicenter, randomized controlled trials of carotid revascularization and intensive medical managem...
As with coronary artery stenting, activation and embolisation of platelets occurs with carotid artery stenting (CAS). Based on promising data on the use of clopidogrel plus aspirin in coro...

The purpose of the Carotid Revascularization Endarterectomy versus Stenting Trial (CREST) is to compare the relatively new procedure of stent-assisted carotid angioplasty (CAS) to the trad...
Cerebrovascular disease is a leading cause of death and the leading cause of serious long-term disability. Carotid artery stenting (CAS) and carotid endarterectomy (CEA) are alternative st...
Blood clot formation in any part of the CAROTID ARTERIES. This may produce CAROTID STENOSIS or occlusion of the vessel, leading to TRANSIENT ISCHEMIC ATTACK; CEREBRAL INFARCTION; or AMAUROSIS FUGAX.
Damages to the CAROTID ARTERIES caused either by blunt force or penetrating trauma, such as CRANIOCEREBRAL TRAUMA; THORACIC INJURIES; and NECK INJURIES. Damaged carotid arteries can lead to CAROTID ARTERY THROMBOSIS; CAROTID-CAVERNOUS SINUS FISTULA; pseudoaneurysm formation; and INTERNAL CAROTID ARTERY DISSECTION.

Pathological conditions involving the CAROTID ARTERIES, including the common, internal, and external carotid arteries. ATHEROSCLEROSIS and TRAUMA are relatively frequent causes of carotid artery pathology.
Narrowing or stricture of any part of the CAROTID ARTERIES, most often due to atherosclerotic plaque formation. Ulcerations may form in atherosclerotic plaques and induce THROMBUS formation. Platelet or cholesterol emboli may arise from stenotic carotid lesions and induce a TRANSIENT ISCHEMIC ATTACK; CEREBROVASCULAR ACCIDENT; or temporary blindness (AMAUROSIS FUGAX). (From Adams et al., Principles of Neurology, 6th ed, pp822-3)
Transient complete or partial monocular blindness due to retinal ischemia. This may be caused by emboli from the CAROTID ARTERY (usually in association with CAROTID STENOSIS) and other locations that enter the central RETINAL ARTERY. (From Adams et al., Principles of Neurology, 6th ed, p245)
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
