Abbott, MD  Journal of Vascular Surgery  Volume 20, Issue 5, Pages (November 1994) DOI: /S (94)70189-X Copyright © 1994 Society for Vascular Surgery and International Society for Cardiovascular Surgery, North American Chapter Terms and Conditions

2 Fig. 1 Actual photograph from screen (A) and scheme of studied arterial segment motions (B). Points a-a' to d-d' are markers for circumferential motions measurements; points 1 to 6 are markers for longitudinal motions measurements; arrows show displacement of points at systole.

3 Fig. 2 A, Overall systolic diameters (mean ± SEM). B, Overall diastolic diameters. BP represents blood pressure (mean ± SEM) during measurements. Open circles represent nonstenosed injured group (n = 5); open squares represent stenosed non-injured group (n = 5); open triangles represent stenosed injured group (n = 14).
