Objective: To investigate cryopreserved allograft transplantation since the vascular graft patency , intimal electron microscope morphological changes in intimal light microscope morphological changes for allograft transplantation and blood vessels deep The cryopreservation method provides the theoretical basis . Method : 2-2.5Kg White Rabbit election by 40 male New Zealand , divided into two groups , 20 in each group , Group A allograft transplantation group , Group B for the group of autologous vascular grafts . Respectively , at 2 weeks, 4 weeks , 3 months after the measurement femoral artery recanalization rate , change intimal electron microscopy , change intimal optical microscopy , the appreciation of the vascular intima . Results: 1. Were compared surgical treatment line × list X ~ 2 test . After X ~ 2 test was of X ~~ 2 = 0.021, p = 989 , the inspection level α = 0.05 , ie , P> 0.05, not statistically significant , that is not yet that allogeneic vascular grafts with autologous vascular graft patency rates are different . 2 in vascular microstructure change , since the the body vascular graft group was superior to cryopreserved allograft vascular transplant group. Conclusion: 1 . Within a short time after the cryopreserved allogeneic vascular transplantation group and since the body vascular graft group patency statistical difference . 2 in vascular microstructure change , since the the body vascular graft group was superior to cryopreserved allograft vascular transplant group.
