Fig 1 A, Mean index segment lumen diameter changes of the entire population, demonstrating early outward remodeling most pronounced between 0 and 1 month, P = B, Scatter plot demonstrating mean and range of remodeling of graft configurations composed of greater saphenous veins in the 0-1 month and 1-3 month time interval. Data shown are for individual grafts with measurements at both of the indicated time points. All values are presented as mean ± SEM.

Fig 2 Great saphenous vein and arm vein index segments remodel in a similar fashion during the first month after bypass grafting. However, they diverge markedly between 1 and 6 months, P < All values are presented as the mean index segment lumen diameter ± SEM.

Fig 3 Early outward remodeling of the index segment is positively correlated with initial vein graft shear stress (r = .54, P = .03). Journal of Vascular Surgery , DOI: ( /j.jvs ) Copyright © 2006 The Society for Vascular Surgery Terms and Conditions

Fig 4 The overall population of grafts showed an increase in wall stiffness (P = .014) during the first 6 months after bypass graft, with the major change observed between 1 and 3 months. Graphed values are presented as the mean ± SEM. Journal of Vascular Surgery , DOI: ( /j.jvs ) Copyright © 2006 The Society for Vascular Surgery Terms and Conditions
