Assessment of TEVG morphometry using microCT angiography demonstrated absence of aneurysmal dilatation or stenosis 12 months after Implantation.

Abstract

<p><b>A.</b> High resolution post-mortem microCT angiography at 12 months post-implantation. The results indicated smooth endoluminal surface and absence of aneurysmal dilatation or stenosis. Yellow bar indicates approximate location of tissue engineered vascular graft. TEVG resemble native aorta on microCT throughout the 12 month-experiment. (n = 5 in each group). <b>B.</b> Luminal volume. MicroCT image processing software was used for the calculation. Because of the difficulty in identifying proximal and distal anastomoses, graft luminal volumes were standardized to a 3mm segment. No significant changes were noted over the course of the experiment.</p
