VAZQUEZ, Dolores et al. Evaluation of Venous Congestion by Point-of-Care Ultrasound: State of the Art. Medicina Interna [online]. 2023, vol.30, n.2, pp.39-46.  Epub 01-Jul-2027. ISSN 0872-671X.  https://doi.org/10.24950/rspmi.1966.

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 physio-logy of venous congestion and the most recent tools for con-gestion assessment by POCUS.
