Abstract:
:The aim of this study was to characterize and compare human great saphenous veins (HGSVs), HGSV cryoallografts, expanded polytetrafluoroethylene (ePTFE) segments, and elastic and muscular arteries' biomechanics, so as to identify if the biomechanical coupling and the HGSV advantages with respect to ePTFE depend on the arterial type and/or on the biomechanical property considered. Pressure and diameter were measured in vitro, under arterial hemodynamic conditions, in elastic and muscular arteries, and in vascular substitutes: fresh and cryopreserved HGSV and ePTFE segments. The wall's dynamics (compliance, viscosity, and inertia), energy dissipation, and buffering were calculated. The coupling was quantified for each biomechanical parameter. Cryopreservation preserved HGSV biomechanics. The HGSV cryoallografts' dynamics, energetics, and buffering were lesser with respect to both arteries, but were higher than the ePTFE. The coupling differed, depending on the arterial type and property considered. The biomechanical coupling depended on the artery and property considered. HGSV cryoallograft advantages over ePTFE were arterial type and property independent.
