Comparison of survival rate in two kinds of lesser saphenous sural pedicled fasciocutanous flaps / 上海第二医科大学学报

ABSTRACT

Objective To compare the survival rate of two kinds of neurovenofasciocutaneous flaps and investigate the venous reverse flow of flaps.MethodsTen New Zealand White rabbits were randomly allocated into 2 groups of 10 flaps(group A the lesser saphenous sural pedicled fasciocutanous flaps,blood supply provided with perforator arteries;group B the lesser saphenous sural pedicled fasciocutanous flaps,blood supply provided with axial type artery).The survival rate of flaps in two groups was observed.Pedicles of flaps were harvested and examined histologically.ResultsThe survival rate of flaps in group A was significantly lower than that in group B[(15.2?16.7)% vs(94.1?6.4)%,P
