Transoral carotid ultrasonographic findings in internal carotid artery dissection--a case report.

Abstract

Transoral carotid ultrasonography (TOCU) is a new method to evaluate the far distal segment of the extracranial internal carotid artery (ICA) and may be superior to conventional carotid ultrasonography in evaluating ICA dissection. The authors report on the use of TOCU in detecting early stage ICA dissection.
