Transcranial Doppler(TCD) Evaluation of High Intensity Transient Signals and Carotid Disease
United States0Started 2013-07-15
Plain-language summary
Carotid Disease causes 10% of strokes. The Investigators are attempting to investigate the use of Transcranial Doppler to see if this is and effective, efficient, and/or valid way to identify individuals at highest risk for thromboembolic events from carotid disease. The plan is to plot the number of high intensity transient transcranial doppler signals with the category of patient (asymptomatic, symptomatic, and actively symptomatic) and evaluate if a relationship exists. The Investigators hypothesize that a linear relationship exists in that the higher the number of HITS the more symptomatic the patient. If results demonstrate the numbers of HITS correlate with the severity of disease this could potentially identify asymptomatic patients having subclinical symptoms who would benefit from a more urgent surgical intervention versus the current standard of care of elective intervention.

Inclusion Criteria:
• Any individual consented for elective or urgent carotid endarterectomy (asymptomatic stenosis \>80% and/or symptomatic carotid stenosis \>50%).
Exclusion Criteria:
* Any individual who is unstable and needs to go to the operating room emergently is excluded from this study.
* Any individual who can not tolerate a TCD exam will be excluded from this study
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
