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.
我们遇到了一例在人工血管移植5年后吻合口处聚丙烯缝线断裂的病例。在扫描电子显微镜下，取出的缝线末端呈逐渐变细的断裂状，末端附近有龟壳样的深裂缝。逐渐变细的残端表明缝线是逐渐被拉伸并最终断裂的。
