The effect of intense arterial constriction on the survival length of an island flap; an experiment using abdominal flaps in rats.
Using rats' abdominal skin flaps, the effects of markedly decreased arterial inflow was investigated. An intense constriction was created with laminated silastic tubes. Survival length of the island flap was reduced by this manipulation and the differences with the control were statistically significant. It was ascertained experimentally that the flap went into necrosis distally and progressed proximally as the arterial inflow decreased. The possible risks of the sleeve technique are also briefly described.
