Ultrasonography for the optimal selection of patients suitable for single session arteriography and endovascular revascularization in severe peripheral artery disease

Peripheral artery disease (PAD) represents a high burden on the healthcare and social assistance systems. Revascularization reduces symptoms, amputation rate and increases the chances of social reintegration. Our aim was to evaluate the benefits of vascular duplex ultrasonography (DUS) for identifying patients suitable for direct percutaneous transluminal angioplasty (PTA) without the need for a prior angiography.
