Abstract(s)

The assessment of venous congestion is one of the grea-test medical challenges of this century: from more invasive procedures to the arising of ultrasound evaluation, there has been a constant quest for reliable and non-invasive bedside tools to determine and monitor hemodynamic status. Venous hypertension is an important pathophysiological mechanism of organ congestion, leading to its injury in various clinical settings. A practical bedside assessment of venous congestion is often challenging due to the limitations of tradi-tional methods.Point-of-care ultrasonography (POCUS) provides a real time picture of the patients' anatomy and physiology (inclu-ding analysis of dynamic flows), allowing a diagnosis and mo-nitoring of venous congestion with a higher sensitivity than standard physical examination.In this brief summary, the authors summarize the physio-logy of venous congestion and the most recent tools for con-gestion assessment by POCUS.
