The altered hemodynamics of arteriovenous fistul lead to overvascularization with trophic hypertrophy of a part or ulceration and tissue necrosis following local circulatory decompensation. A twenty years old female had been suffered from chronic ulcerative dermatitis on the dorsal aspect of left foot and multiple hemangioma on ber left great toe. The ligation of main communicating vessel and excision of fistula masses were performed in the surgical treatment. The ulceration on the dorsal aspect of left foot was healed completely and the size of hemangioma was reduced.
