1 Standard duplex criteria overestimate the degree of stenosis after eversion carotid endarterectomy 
Travis Benzing, BS, Cameron Wilhoit, BA, Sharee Wright, MD, P. Aaron McCann, BE, BS, Susan Lessner, PhD, Thomas E. Brothers, MD  Journal of Vascular Surgery  Volume 61, Issue 6, Pages (June 2015) DOI: /j.jvs Copyright © Terms and Conditions

3 Fig 2 Correlation of peak systolic velocity (PSV) on surveillance duplex imaging after eversion carotid endarterectomy (eCEA) with measurements from axial imaging as calculated by North American Symptomatic Carotid Endarterectomy Trial (NASCET) criteria, European Carotid Surgery Trial (ECST) criteria, and cross-sectional area (CSA) reduction.

5 Fig 4 Mean luminal diameter of internal carotid arteries (ICAs) with peak systolic velocity (PSV) >125 cm/s as a function of distance from the bifurcation. Negative distance values indicate measurements proximal to the bifurcation. All differences between eversion carotid endarterectomy (eCEA; n = 19) and patch closure carotid endarterectomy (pCEA; n = 8) are statistically significant (P < .05) except for measurements from −9 mm to −0.5 mm.
