Graft compliance
WebStiff grafts may impede pulsatile flow and interfere with energy propagation. In vivo compliance (C, % radial change/mm Hg X 10-2 ± SEM), derived from pressure and diameter measurements, was assessed in 38 arteries and 60 arterial grafts in a standardized canine femoral artery bypass model. WebConclusion: In this in vitro model, PET graft compliance has already decreased significantly within 3 h. The rapid loss of compliance identified in this experimental study helps explain the mismatch mentioned in clinical observations. AB - Objective: Compliance is considered to be a major property influencing the long term performances of ...

Compliance of two stent grafts incorporated with polyurethane graft (nitinol-PU) and polyester graft (nitinol-PET) materials respectively were tested; the stents used in the two stent grafts were identical.
WebOct 30, 2013 · The graft compliance calculated by the two methods was very similar. A study by Glineur et al. has shown that in the resting conditions the pressure drop along the LITA is 2.9 ± 2.2 mmHg and along the SVG only 0.4 ± 0.7 mmHg. Thus, the pressure along the graft is nearly identical in open and occluded grafts and the volume changes of the … WebSep 28, 2024 · Graft compliance was defined as the director coefficient of the tangent-line to the force–displacement curve at any given point (using the polynomial equation: f ( x ) = ax3 + bx2 + cx + d ).
WebJan 14, 2024 · Compliance is defined in vascular graft engineering as the elasticity of the conduit when exposed to internal pressure ( Szafron, 2024 ). The commercially available synthetic grafts, such as expanded polytetrafluoroethylene (ePTFE) and Dacron, have significantly lower compliance than native blood vessels ( Tai et al., 2000 ).
