Transcranial Doppler(TCD) Evaluation of High Intensity Transient Signals and Carotid Disease

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.

Conditions

  • Asymptomatic Carotid Stenosis
  • Symptomatic Carotid Stenosis
  • TCD
  • HITS

Interventions

DEVICE

Transcranial Doppler (TCD)

All individuals who are consented for elective or urgent carotid endarterectomy would be eligible to participate. If patient gives consent, they would undergo an approximately 30-60 minute TCD study. We will collect the number of high intensity transient signals (HITS). The patient would undergo surgery regardless of the TCD result.
