Fig 1 Mean levels of markers of coagulation or platelet activation in patients receiving plain expanded polytetrafluoroethylene (ePTFE) or Propaten grafts (W. L. Gore & Associates, Flagstaff, Ariz) at various times after surgery compared with preoperative levels. Error bars indicate standard error of mean. sGPV, soluble glycoprotein V; F1+2, prothrombin fragment 1+2; FPA, fibrinopeptide A; TAT, thrombin-antithrombin complexes.

Fig 2 Mean platelet count of patients receiving either a Propaten (W.L. Gore & Associates, Flagstaff, Ariz) or expanded polytetrafluoroethylene (ePTFE) graft at various times before and after surgery. Error bars indicate standard error of mean.

Fig 3 Absolute platelet count of a patient who received an expanded polytetrafluoroethylene (ePTFE) graft but was excluded from the analysis because systemic heparin was needed for 4 days postoperatively. A 45% decline in platelet count was observed at day 5, which recovered up to normal levels at week 6; moreover, no heparin/platelet factor 4 complex antibodies developed in this patient.
