Late spontaneous nonanastomotic transgraft hemorrhage from biological material-impregnated fabric vascular graft may be due to autologous tissue detachment: a clinical hypothesis.
Spontaneous nonanastomotic transgraft hemorrhage occurring several years after grafting may be a new late complication of biological material-impregnated fabric vascular grafts (BMIFVs). Autologous connective tissue detachment may be caused by high porosity of the fabric graft and high blood pressure. Bleeding around the fiber is the first sign of development. Fabric grafts with optimal porosity and biocompatibility should be used for manufacturing BMIFVs.
