[An animal model of venous congested flap for long-term microcirculation study].
OBJECTIVE
To set up a venous congested flap model to study the mechanism of necrosis through long-term microcirculation observation.


METHODS
A specially deviced chamber was assembled to one side of the ears in an adult white rabbit, about 7 approximately 10 days after the operation the congested flap model was made and the microcirculatory status of the flap was dynamically observed under a vivo-microscope for a long time.


RESULTS
The venous crisis phenomenon of flap was well studied and the microcirculation of the flap was observed carefully, finally the variational rule of the congestion flap microcirculation was made clear.


CONCLUSIONS
The model could well simulate the venous crisis flap in clinic, and the microcirculation could also be observed for a long time.
