Fig. 7 IVUS images of extensive motion of wall of one uncrimped vascular prosthesis during arterial pulsation at implant. A, Maximal expansion and (B) maximal collapse of graft. C, IVUS image and (D), gross inspection of same segment of prosthesis at 30 days demonstrates narrowing of graft (triple arrows) that occurred in area of wall motion. Single arrows, Aortic wall; double arrows, vascular prosthesis. All IVUS figures are of comparable magnification to permit comparison of luminal dimensions at time of implantation and 30-day interval.
