RESUMO
Venous ulcers caused by venous hypertension secondary to arteriovenous fistulae are rare. Their etiology can be confirmed by vascular Doppler ultrasonography, which can differentiate between stenosis of central vessels and hemodynamic overload caused by development of tributaries from the vein responsible for the arteriovenous fistula. We present a case caused by hemodynamic overload of a tributary, which diverted the primary flow from the fistula to the distal limb. We chose to ligate the fistula to treat the ulcers and create another arteriovenous fistula in the contralateral limb.
