Experimental studies and clinical application of quickly prefabricated random skin flap / 中华整形外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To enlarge the ratio of length to width of a prefabricated random skin flap in a short period, in order to meet a special clinical need.</p><p><b>METHODS</b>A white rat and a white mini-pig was chosen for an animal model for the experiment. They were divided into the experimental group and the control. The prefabricated flap was formed as the planned design. In the experimental group, the flaps were treated with a desired pressure in certain intervals at the planned part of the flap. We estimated and inspected the digitized perfusion of flap microcirculation, and made overcong and wide random skin flap survive within 24 hours, and this technique was finally used for the clinical wound treatment.</p><p><b>RESULTS</b>As expected, the survival area of the flap in the experimental group was significantly larger than the control. This technique was successfully used to repair the defects of the special sites in plastic and reconstructive surgery.</p><p><b>CONCLUSION</b>The method of quickly prefabricated random flap could enlarge the ratio of length to width of the flap and put the flap in shape in short time. With the digitized estimating and inspecting, this method could obviously improve the survival area of the random flap and could also be very useful for the clinical treatment.</p>
