Tema(s): Recursos en línea: Resumen: Mechanical matching of vascular grafts and host vessels has been suggested to be important in determining graft patency rates. In this context, we have examined the anisotropic viscoelastic prbperties of natural vessels and some synthetic replacements using low strain rate tensile testing of circumferential and longitudinal strips. The canine iliac artery and iliac vein were compared with 6 mm diameter woven and knitted Dacron@ grafts, expanded polytetrafluoroethylene (PTFE)grafts, and helically constructed prototype polyurethane grafts at wrap angles of 45, 60 and 75". A thick-walled pressure vessel analysis was used to approximate physiological stress levels, and SEM was used to correlate anisotropic properties with graft wall structure.
