2、ective:To study the different expression of vascular endothelial growth factor (VEGF) in hemangioma and vascular malformation and provide an efficacious index for distinguishing hemangioma from vascular malformation, and for guiding the treatment or checking up the treatment
3、effect of hemangioma.Method:Immunohistochemistry S8P method was used to test the expression of VEGF at each stage of hemangioma, in vascular malformation and normal blood vessels.Results:An intensive expression of VEGF was found in hemangioma with a higher expressive rate at
4、 the proliferative stage than at the earlier or later paracmastic stage(P<0.05).No expression of VEGF was found in normal blood vessels and vascular malformation.Conclusion:The higher expression of VEGF found in hemangioma has obvious correlation with different stages of t
