ABSTRACT
<p><b>OBJECTIVE</b>To investigate the systemic influence after an island flap with venous congestion-reperfusion.</p><p><b>METHODS</b>An island flap was formed in a Rat model. The vein in the pedicle was clamped for 2 hours, 6 hours and 10 hours and released. The ear microcirculation, levels of TNF alpha and IL-10 were measured, and the neutrophils sequestration in tissues were counted. The vascular structure of the lung and intestine were evaluated.</p><p><b>RESULTS</b>There were significant changes in the ear microcirculation, neutrophils sequestration of the lung and the intestine in the 2 hours, 6 hours and 10 hours groups, and became more serious by the time increasing. The TNF alpha level reached in maximum at 1 hour after the reperfusion, while the IL-10 became to the lowest level at 3 hours after the reperfusion. However, the TNF alpha and IL-10 levels were significant high in the 6 hour and 10 hours groups, compared with the 2 hours group and the control, but there was no differences between the2 hours group and the control.</p><p><b>CONCLUSIONS</b>Venous congestion-reperfusion of flap could injury the remote organs such as lung, intestinal etc. The injury could be more serious with the time increasing.</p>
