Classificação angiográfica na revascularização do membro inferior isquêmico: pode a angiografia definir a resistência do leito receptor do enxerto? Angiographic classification in ischemic lower limb revascularization: can it define arterial outflow resistance?

Background: Angiography is often used as the only preoperative method to define the therapeutic approach for ischemic lower limb revascularization, either by transluminal angioplasty or surgery. Today its use is still controversial. Objective: To compare a simple method of angiographic classification with hemodynamic preoperative and intraoperative studies of the ischemic arterial bed in order to verify its efficacy in defining arterial bed resistance.
