Abstract:
Purpose: To investigate the axis tension-strain relation of femoral arteries and veins in rabbit and to evaluate the particular reference to the option of vascular repair. Methods: A mechanical analysis of stretch experiment was undertaken to evaluate the axis tension-strain relation of femoral arteries and veins in rabbit. Results: In 35.0 mm, the curve regression equation of femoral artery between the tension and the stretch ratio was shown: Fa=0.22(e5.75(λa-1)-1); and the curve regression equation of femoral vein between the tension and the stretch ratio was shown: Fv=6.15 ×10-3(e7.89(λv-1)-1). Conclusion: It suggested to repair the injuried vessel according to the actual defect length and the actual isolated length(AcIL). The length of vein graft (LVG) was shown: (LVG/λv) × λv + (RIL/λa ) ×λa=AcIL,RIL(Residual isolated length)=AcIL-LVG.
