The assessment of venous congestion is one of the greatest 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 traditional methods. Point-of-care ultrasonography (POCUS) provides a real time picture of the patients' anatomy and physiology (including analysis of dynamic flows), allowing a diagnosis and monitoring of venous congestion with a higher sensitivity than standard physical examination. In this brief summary, the authors summarize the physiology of venous congestion and the most recent tools for congestion assessment by POCUS.
