Abstract:Postoperative dilatation of Dacron vascular grafts can lead to aneurysms and rupture of the prosthesis making it necessary to change the graft by operation. Therefore, 15 patients at Lübeck University Hospital underwent replacement of the aorta with PTFE prostheses due to infrarenal aortic aneurysms.
