Abstract:
Objective To determine the difference of microvessel density(MVD) in each layer and region of abdominal flap. MethodsFlaps were obtained from 60 patients with abdominal operations,10 in each of the regions from I to VI.The vascular endothelial cells were marked with CD34 by immunohistochemistry,and the MVD in each region and layer of the abdominal flaps was determined.Results The vascular net of abdominal flap was divided into five layers: papillary layer of corium,papillary underlayer of corium,papillary deep layer of corium,superficial fascia and deep fascia.The mean MVD of the five layers were 17.80?1.68,9.12?1.84,27.91?2.44,37.18?6.55 and 46.91?7.02,respectively,with significant differences among them(P0.05).Conclusion Anatomic factors may be responsible for the survival of large abdominal flaps.Either of the direct and retrograde motion is feasible in the transplantation.
