Symptomatic carotid pathology detected by duplex ultrasound with minimal disease on angiography.

Carotid duplex ultrasound has been shown to give a more thorough picture of carotid plaque morphology than a carotid arteriogram. As a result, the question has arisen regarding what should be done for the patient who presents with classical hemispheric transient ischemic attacks (TIA) with ulcerative carotid plaque as documented by carotid duplex ultrasound, but with minimal disease on arteriography. This article presents a case illustration of this problem.
