Learning objectives Spectral Doppler waveform assessment is a crucial diagnostic tool employed in identifying peripheral arterial  diseases. The prevalence of conflicting and overlapping Doppler waveform terminologies has been a long-standing concern. To address this issue, the Society for Vascular Medicine (SVM) and the Society for Vascular Ultrasound (SVU) initiated a writing committee comprising experienced sonographers and physicians. Their collective expertise in ultrasound performance, interpretation, research, and teaching led to the development of an expert consensus document aimed at proposing a universal nomenclature...
Read more Background The terms triphasic, biphasic, and monophasic, that were used to describe arterial waveforms, lack standardized application. Triphasic, commonly denoting normal arterial flow, has been inconsistently applied to abnormal waveforms. Biphasic has been used for both normal and abnormal flow patterns, and monophasic, typically indicating abnormal flow, has variable applications. The lack of standardization, including terms like phasicity and the absence of a zero-flow baseline, has led to confusion.Standardizing Doppler waveform nomenclature is crucial for accurate communication of vascular diagnostic test...
Read more Findings and procedure details Nomenclature Purpose: to clarify and standardize essential definitions and descriptors in the analysis of arterial Doppler waveforms.Reference baseline for spectral Doppler waveforms universally defined as the zero-flow baseline.Reporting arterial spectral Doppler involves key descriptors (flow direction, phasicity, resistance) and optional modifier terms for additional insights.The normal peripheral arterial waveform includes a sharp systolic peak, an early diastolic notch or early diastolic reversal, and a positive end diastole.

Read more Conclusion In conclusion, this comprehensive poster delves into the intricate nuances of peripheral arterial waveforms, offering insights into various arteries. By examining the characteristics and variations in Doppler waveforms, we gain a profound understanding of normal and abnormal flow patterns. From multiphasic to monophasic waveforms, the poster elucidates the distinct features associated with different degrees of arterial stenosis and specific clinical conditions, such as pseudoaneurysms and arteriovenous fistulas. The detailed analysis provided serves as a valuable reference for practitioners involved in...
