Abstract: Objective:To evaluate the effect of the treatment vascular malformation with endovascular embolization through percutaneous guided by digital subtraction angiography(DSA).Methods:Twenty cases with vascular malformation on surface were confirmed according to clinical and imaging features(including artery malformation 7 cases,vein malformation 9 cases,arteriovenous malformation 4 cases).Eleven cases of artery and arteriovenous malformation were treated with bleomycin and polyvingl alcohd,the other 9 cases were injected with bleomycin and ethanol guided by DSA,each course interval was 3 weeks.Results:The anomalies in 12 cases were cured,favorable improvement in 8 cases.No cases appeared tissue necrosis and skin burst.Conclusions:The treatment mothod for vascular malformation is easy,safe and effective,and can reduce or avoid complications,worth populararizing in clinical practice.
