The two divergent angiographic grading methods used for internal carotid artery stenosis in these trials have caused confusion in the clinical application of their recommendations. Moreover, while today's highly accurate carotid duplex scanning can obviate the need for preoperative angiography in many cases, the duplex criteria must be tailored to achieve sufficiently reliable results on which therapeutic decisions can be made. This review offers a clarification of the discrepancies between the angiographic grading techniques and how their measurements of percent stenosis correlate to the duplex criteria needed to support the treatment decision-making process for carotid obliterative disease.<\/jats:p>","DOI":"10.1177\/152660289600300207","type":"journal-article","created":{"date-parts":[[2015,3,20]],"date-time":"2015-03-20T21:31:11Z","timestamp":1426887071000},"page":"158-165","source":"Crossref","is-referenced-by-count":20,"title":["Angiographic
