NCT00178451

Brief Summary

In the first portion of the study, the goal will be to determine the safety of the drug Abciximab for use during and in the period after open carotid artery surgery. In addition, using specialized ultrasound equipment (a probe that is placed on the outside of your skin of your head), we will aim to measure the number of particles released around the time of surgery while being treated with Abciximab. The second phase of the study will be determine if Abciximab can safely reduce the number of particles released into the bloodstream around the time of surgery in order to reduce the risk of stroke.

Outcome Measures

Primary Outcomes (1)

  • the safety of Abciximab in patients undergoing carotid endarterectomy. This dose ranging study will seek to define the optimal dose regimen for safe use of Abciximab in patients with asymptomatic >75% carotid artery stenosis.

Secondary Outcomes (1)

  • Determine incidence of microemboli recorded on transcranial Doppler imaging during carotid endarterectomy with use of Abciximab.
