[Aneurysmal complication of a dacron vascular prosthesis]

Arterial prosthesis employed in the University Hospital Center, Homburg en Sarre, F.R.G. since 1972 have mainly consisted of knitted velvet dacron for internal insertion. Aneurysms at the site of anastomoses are a known complication and several cases have been observed, but no reports of aneurysms at the level of a prosthesis appear to have been published. This complication occurred twice in the same patient with a interval of fifteen months. Based on the results of experimental data, the question is raised as to whether this complication is the consequence of degradation of the dacron by monocytic elements.
