[The changes of micrangium density of the reverse-flow random flap with a superficial venous trunk: an experimental study using stereological methods].

Objective: To study the effects of the superficial venous trunk (SVT) and its nourishing vessels on early revascularization of the reverse-flow random flap in order to provide theoretical evidences for clinical applications.

Methods: The morphologic changes of micrangium of the reverse-flow random flap with SVT and without SVT were observed at different phases and compared by optical microscopy and stereological methods.

Results: The micrangium density of the flaps with SVT and without SVT showed a tendency of increasing at 3 days after the operation.
