Collagen External Scaffolds Mitigate Intimal Hyperplasia and Improve Remodeling of Vein Grafts in a Rabbit Arteriovenous Graft Model

Figure 2

CES markedly improves the hemodynamic stability of the vein graft. (a–f) Columnar diagrams show the results of vascular ultrasound examination. The CES effectively inhibited the expansion and prevented the reduction of the blood velocity and flow of the vein graft. N: no-graft group; G: graft group; G + S: CES group. versus no-graft group; versus graft group.
