Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This will be a pilot study of 9 patients undergoing standard-of-care clinically indicated carotid endarterectomy. The nine patients will receive an injection of Indocyanine green (ICG) at a dose of 0.25 mg/kg (maximum 25 mg) as an intravenous bolus.

Immediately following endarterectomy, the resected specimen will be immersed in normal saline. Ex vivo fluorescence reflectance imaging (FRI) and immunohistochemistry will be performed.

The investigators hypothesize that compared to controls, ICG-injected patients will demonstrate increased ex vivo and microscopic ICG fluorescence signal within areas of plaque.
