Society of Diagnostic Medical Sonography

This virtual session provides an in-depth review of the transition from normal hepatic and portal venous physiology to abnormal Doppler flow patterns encountered in clinical sonography. Participants will explore key Doppler principles and waveform characteristics associated with portal hypertension, cirrhosis, and cardiac dysfunction. Emphasis is placed on developing a structured, practical approach to interpreting hepatic and portal venous flow in routine vascular imaging.

• Review normal hepatic and portal venous anatomy and physiology to establish a baseline for Doppler interpretation.
• Identify key Doppler ultrasound parameters used in the evaluation of hepatic and portal venous flow.
• Correlate abnormal hepatic and portal venous flow patterns with underlying hepatic and systemic pathologies.

This virtual session provides an overview of pelvic venous disorders (PeVD), focusing on their etiology, pathophysiology, clinical presentation, and classification. Participants will review key imaging findings and diagnostic criteria while developing a structured approach to sonographic evaluation. The session also emphasizes a practical protocol to support accurate and consistent clinical assessment of PeVD in vascular sonography practice.

• Describe the etiology, pathophysiology, and spectrum of pelvic venous disorders.
• Identify the classification system, clinical subsets, and associated symptoms of pelvic venous disorders.
• Recognize imaging findings and diagnostic criteria and apply a systematic sonographic protocol for evaluation.

This virtual session provides a comprehensive review of venous reflux evaluation using duplex ultrasound, with emphasis on waveform analysis and hemodynamic assessment of the deep and superficial venous systems. Participants will review venous anatomy, examination protocols, patient positioning, and reflux testing techniques. The presentation highlights physiologic and pathologic Doppler waveform patterns, with application to chronic venous insufficiency across major venous segments, including superficial, perforator, and deep systems.

• Describe venous anatomy and hemodynamics of the deep and superficial venous systems relevant to reflux evaluation.
• Review duplex ultrasound protocols, including patient positioning and reflux testing techniques.
• Differentiate normal and abnormal venous Doppler waveforms associated with chronic venous insufficiency.
• Identify reflux patterns in the great saphenous, small saphenous, perforator, and deep venous systems.
• Apply waveform analysis to improve diagnostic accuracy and clinical interpretation in venous reflux studies.

This virtual session provides an in-depth overview of duplex ultrasound evaluation in Deep Venous Arterialization (DVA) for patients with chronic limb-threatening ischemia who have limited treatment options. Participants will review pre-procedural mapping, patient selection, and the spectrum of venous arterialization techniques. Emphasis is placed on post-procedural surveillance, including hemodynamics, conduit patency, pedal venous maturation, and key ultrasound findings that support limb salvage outcomes.

• Describe duplex ultrasound principles used to evaluate Deep Venous Arterialization, including conduit patency and flow characteristics.
• Identify expected hemodynamic changes following DVA and their clinical significance in patient monitoring.
• Recognize key ultrasound findings associated with successful and unsuccessful DVA outcomes.
• Apply a standardized sonographic surveillance protocol to assess post-DVA patients and support clinical decision-making.
