An animal model of venous congested flap for long-term microcirculation study / 中华整形外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To set up a venous congested flap model to study the mechanism of necrosis through long-term microcirculation observation.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSIONS</b>The model could well simulate the venous crisis flap in clinic, and the microcirculation could also be observed for a long time.</p>
