Usefulness of Blood Flow Measurement Device Using Bioelectrical Impedance Plethysmography in Lower-Extremity Artery Disease.

Background: Bioelectrical impedance plethysmography (IPG) for measuring human body fraction and disease has been progressing in the past half-century, and few studies have reported lower-extremity arterial disease (LEAD) in recent years.

Methods And Results: The present study enrolled patients who underwent examinations for LEAD. IPG with venous occlusion was performed, and flow volumes were compared with those measured using Doppler duplex ultrasonography, the ankle-brachial index (ABI), and assessments of arterial stenosis and collaterals using computed tomography and/or magnetic resonance angiographies.
