a Each group was performed by 10 animals; Dacron1–6, groups of animals by implantation of Dacron protheses; ePTFE1–6, groups of animals by implantation of ePTFE protheses.
b Graft segments were impregnated with 1 mg/ml teicoplanin; 1 mg/ml levofloxacin.
c Teicoplanin 10 mg/kg, levofloxacin 10 mg/kg.
d Statistically significant when compared with group Dacron2
e Statistically significant when compared with group ePTFE2
