Deterioration of suture materials at prosthetic-host anastomoses.
We experienced a case of polypropylene suture rupture at anastomosis 5 years after fabric vascular graft implantation. Under a scanning electron microscope, the removed suture had a tapering-off breakage at the end and tortoiseshell-like deep cracks near the end. The tapered stump indicated that the suture had been stretched out gradually and had finally fractured.
