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. ResumoÚlceras venosas decorrentes de hipertensão venosa por fístula arteriovenosa são raras. A investigação de sua etiologia é esclarecida pelo eco-Doppler vascular, que diferencia entre estenose de vasos centrais e sobrecarga hemodinâmica gerada pelo desenvolvimento de tributárias, a partir da veia responsável pela fístula arteriovenosa. Apresentamos um caso gerado por sobrecarga hemodinâmica em tributária, que desviou o fluxo principal da fístula distalmente ao membro. Optamos por realizar a ligação da fístula para tratamento das úlceras e confecção de nova fístula arteriovenosa em membro contralateral.
