Carotid Artery Tandem Lesions:Frequency of Angiographic Detection and Consequences for Endarterectomy AJNR 20:621-625, Rouleau,P.A.,et al, 1999 See this aricle in Pubmed Article Abstract Six hundred seventy-two of the 853 patients had a carotid bifurcation stenosis of 70% or greater or underwent an endarterectomy. Of these, a carotid siphon stenosis of 50% or greater was noted in 65 patients (9.7%) and was ipsilateral to an ICA stenosis in 37 patients (5.5%). A common carotid stenosis was present in 29 patients (4.3%), ipsilateral to an ICA stenosis in 14 patients (2.1%). A stenosis of 50% or greater within the proximal intracranial circulation was present in 28 patients (4.2%), ipsilateral to an ICA stenosis in 15 patients (2.2%). Four patients had tandem stenoses at more than one site. Tandem stenoses in the siphon or intracranial segments were noted in 13.5% with a bifurcation stenosis and in 8.8% of those with no bif urcation stenosis. Endarterectomy was performed in 48 of the 66 patients with tandem stenotic lesions. The presence of a tandem lesion infrequently alters the surgeon's decision to perform an endarterectomy. However, the important implications for long -term medical management in symptomatic patients.
