Carotid stenosis: factors affecting symptomatology.
BACKGROUND AND PURPOSE The ability to predict future strokes in asymptomatic patients with carotid stenosis is currently limited. The management of symptomatic patients with <50% stenosis is also debatable. In this context, we performed the following open prospective study to identify factors affecting symptomatology in patients with carotid stenosis. METHODS During 1988-1997, 442 arteries wi...
متن کاملMicroembolic signals and carotid plaque characteristics in patients with asymptomatic carotid stenosis.
OBJECTIVE To investigate the association between carotid plaque characteristics and the occurrence of cerebral microemboli signals (MES) and subsequent ischemic events in patients with asymptomatic carotid stenosis (ACS). DESIGN Sixty-two asymptomatic patients with 50-99% carotid stenosis underwent transcranial Doppler (TCD) monitoring to determine the relationship between MES and plaque char...
متن کاملSource of microembolic signals in patients with high-grade carotid stenosis.
BACKGROUND AND PURPOSE In patients with both symptomatic and asymptomatic carotid artery stenoses, the relationship between carotid plaque characteristics and transcranial Doppler (TCD)-detected microembolic signals (MES) is unclear. The purpose of this study was to examine the relationship between macroscopically described plaque characteristics and MES in patients undergoing carotid endartere...
متن کاملAspirin inhibits human telomerase activation in unstable carotid plaques
The activation of telomerase in unstable plaques is an important factor in atherosclerosis, and may be predictive of the risk of cerebrovascular diseases. Human telomerase reverse transcriptase (hTERT) is a subunit of telomerase that is essential for telomerase activation. The aim of the present study was to investigate whether aspirin inhibits the activation of telomerase and hTERT in unstable...
متن کامل18FDG-PET-CT: an imaging biomarker of high-risk carotid plaques. Correlation to symptoms and microembolic signals.
BACKGROUND AND PURPOSE We investigated whether uptake of (18)fluoro-2-deoxy-d-glucose (18FDG) positron emission tomography-computed tomography (PET-CT) correlated to clinical symptoms and presence of microembolic signals (MES) detected by transcranial Doppler in patients with carotid stenosis. METHODS 18FDG-PET-CT and MES detection was performed in consecutive patients with 50% to 99% symptom...
