Regular follow\u2010up with duplex carotid ultrasound was performed to assess for restenosis. Univariate Cox regression analysis was performed to evaluate the association between the presence of a CCO and repeat revascularization.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean patient age was 70\u2009years.

During 5\u2010year follow up, the rate of duplex\u2010derived &gt;80% stenosis was 6% in the non\u2010CCO group and 9% in the CCO group (<jats:italic>P<\/jats:italic>\u2009=\u20090.45). Despite similar rates of &gt;80% restenosis, there was a significant association between CCO and subsequent target\u2010lesion revascularization (TLR), with rates of 6.4% vs 0.9% at 5 years (HR 7.2, confidence interval (CI) 1.2\u201343, <jats:italic>P<\/jats:italic>\u2009=\u20090.04).
