Abstract:
We experienced unusual dilatation of gelatin-impregnated knitted Dacron prostheses after abdominal aortic aneurysm surgery. Therefore, we investigated dilatation of gelatin impregnated knitted Dacron grafts compared with other types of Dacron grafts after abdominal aortic aneurysm surgery. Eighteen grafts inserted after abdominal aortic aneurysm surgery were studied for to evaluate dilatation. Enhance CT was used to determine the external diameter of the most dilated portion of the abdominal aortic grafts and high speed plain CT was used to determine the most dilated internal diameter. The gelatin-impregnated knitted Dacron grafts dilated from 25% to 43.8% (mean 31.8±7.2%), significantly more than collagen impregnated woven Dacron grafts (p=0.0003). Moreover, high fever was frequently noticed after these grafts implantation (66.7%). Therefore, caution must be used concerning these implantation in aortic lesions and careful follow-up study should be performed after implantation.
