1 Major carotid plaque surface irregularities correlate with neurologic symptoms 
Aaron Troyer, BA,, David Saloner, PhD,, Xian Mang Pan, MD,, Pauline Velez, MD,, Joseph H. Rapp, MD,  Journal of Vascular Surgery  Volume 35, Issue 4, Pages (April 2002) DOI: /mva Copyright © 2002 Society for Vascular Surgery and The American Association for Vascular Surgery Terms and Conditions

2 Fig. 1 Plaque specimen removed by means of the “en bloc” method to prevent destruction of the plaque lumen. Journal of Vascular Surgery  , DOI: ( /mva ) Copyright © 2002 Society for Vascular Surgery and The American Association for Vascular Surgery Terms and Conditions

3 Fig. 2 High resolution MRI sagittal section of plaque. The resolution is 200 mm, with each slice thickness also 200 mm. Cross-sectional images can be reviewed in any selected angle. In this section, invaginations and a ledge in the ICA can be seen.

4 Fig. 3 Plaque lumens were assigned to four categories as depicted. Top left, circular; top right, crescentic; bottom left, multi-lobular; bottom right, elliptical.

5 Fig. 4 The location of the bulk of plaque creating the maximal stenosis was determined to be in the CCA (top), at the bifurcation (middle), and within the ICA (bottom).

6 Fig. 5 Frequency distribution of the degree of stenosis as measured by means of high-resolution MRI for the 100 plaque specimens. Journal of Vascular Surgery  , DOI: ( /mva ) Copyright © 2002 Society for Vascular Surgery and The American Association for Vascular Surgery Terms and Conditions

7 Fig. 6 Frequency distribution of the lumen shapes.

8 Fig. 7 The distribution of the bulk of plaque along the FDW and the NFDW of the ICA. Top: Plaque located on the NFDW. Middle: Plaque located on the FDW. Bottom: Plaque equally distributed between the NFDW and the FDW.
