Duplex-Guided Balloon Angioplasty from the Carotid to the Plantar Arteries
Over the last 12 years, our group has explored advantages and limitations of preoperative duplex arteriography of lower extremities as a sole imaging modality [1,2]. This experience has taught us that duplex scanning offers multiple unique features such as (1) arterial visualization regardless of its patency, (2) imaging of the arterial wall, (3) real-time visualization in the presence of limb motion, (4) up to five times magnification, (5) instant precise measurements, and (6) readily available various hemodynamic parameters such as flow direction, velocity, and waveform. These distinctive features have manifested into the use of duplex imaging for guidance of various venous and arterial therapies such as endovenous procedures and thrombin injection of pseudoaneurysms and have helped to establish the field of interventional vascular ultrasound.
