Summary of "Carotid Stenting and Transcranial Doppler Monitoring: Indications for Carotid Stenosis Treatment."

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).

Medical and Biotech [MESH] Definitions

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. (From Am J Forensic Med Pathol 1997, 18:251; J Trauma 1994, 37:473)

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)
