Recent literature advocates carotid endarterectomy on duplex alone. The authors hypothesized that carotid angiography adds information that alters clinical management in a substantial number of @entity1 compared to the use of carotid duplex examination alone. The records of 182 consecutive @entity1 who underwent @entity2998 duplex and subsequent carotid/cerebral angiography for suspected @entity543 between January 1998 and April 1999 were reviewed retrospectively. Carotid artery duplex examinations were stratified based on @entity850 : < or =39%, 40% to 59%, 60% to 79% (moderate), 80% to 99% (severe), 100%. @entity543 on angiograms was determined by NASCET criteria. New information found at angiography included vertebral, subclavian, or arch @entity731 , intracranial pathosis, or a change in duplex @entity850 category to a degree of @entity850 not requiring surgery. Clinical importance was attributed to angiograms that altered the @entity1 ' management plan. Angiography provided additional information in 53% (97/182) of @entity1 . @entity66 was found in 25.1%, @entity66 in 16.4%, @entity1504 in 15.3%, aortic arch disease in 3.3%. @entity1 treatment was altered in 30% (55/182). Angiographic findings downgraded the @entity850 to medical therapy in 20.9% (38/182). The surgical plan was influenced in 5.5% (10/182). Nine @entity438 were discovered. Carotid angiography was essential for vascular bypass surgery planning in 3.3% (6/182). Angioplasty was performed in 2.2% (4/182). The accurate determination of @entity850 is critical in determining optimal treatment of @entity1 with @entity543 . Routine carotid angiography remains valuable in the clinical treatment of these @entity1 .

Carotid arteriography impacts carotid XXXX management.
