Small Saphenous Vein Embolization For Phil Bowel Neurotrophic Vascular Pedicle Flap Influence Distal Is Studied

Objective Through to the rabbit phil bowel neurotrophic vascular retrograde flap small saphenous vein embolization of research, Observe the flap survival rate of the influence, And the small saphenous vein with the traditional processing method are compared, So as to guide the flap of clinical application. Methods 2009 September to October, 2010, Choose good health big white rabbit, only 30, According to the rabbit phil bowel neurotrophic vascular retrograde small saphenous vein skin flap different ways to deal with random into three groups(pending group, ligation group, embolism group), Every day the color of postoperative observation flap, and swelling, The first 10 days after the area of skin flap survival determination, To compare the percentage of live area. Postoperative day 10 separation, cut take small saphenous vein embolization period, macroscopic observation flaps cut small saphenous vein stem of change, And do biopsy, HE dyed, As light microscopy small saphenous vein embolization effect. Results Small saphenous vein embolization group less treatment group, ligation group compared with significant flap survival differences(P<0.05), and the value for the difference was statistically significant mean, Show embolism is pending curative effect of group, ligation group is superior. Conclusion Small saphenous vein embolization method also reserves on the ankle deep vein position and the backflow, Avoid ligation small saphenous vein damage the blood circulation danger's, Also need not and the area venous microanastomosis flap, to avoid the retrograde blood perfusion, The swelling, passive flap venous disorders, such as resolutely complications of skin flap necrosis, Improve distal Wendy phil bowel neural nutrient vessels of the flap survival rate.
