Use of carotid ultrasound as a preoperative assessment of extracranial carotid artery blood flow and vascular anatomy.
Carotid ultrasound evaluation as a preoperative assessment of internal carotid artery blood flow and anatomic stenosis is efficacious and safe. The technique, although operator dependent, is both inexpensive and easily repeated with essentially no risk to the patient. Furthermore, when combined with MR angiography, it usually can obviate the need for angiography in most endarterectomy candidates.
