Background and Aims: The venous excess ultrasound (VExUS) score presents a prospect of valuable clinical utility. The study aimed to systematically review the effectiveness of the VExUS score in detecting venous congestion across emergency, critical care, and peri-operative contexts; assessing its utility in improved patient outcomes; and exploring its relationship with established parameters. Methods: This systematic review was registered in the International Prospective Register of Systematic Reviews (CRD42023421034). A comprehensive literature search, employing pre-defined search terms related to the VExUS score in diverse clinical contexts, was conducted on articles published between 2000 and 15 May 2023 across databases- PubMed, PubMed Central, Cochrane, Scopus, Elsevier Clinical Key, and Google Scholar. Bias risk assessment was carried out using the Risk of Bias in Non-Randomised Studies tool. Given the significant heterogeneity across studies concerning participants, interventions, outcomes, and study designs, data pooling for a meaningful meta-analysis was not feasible. Results: The review included 15 articles comprising observational studies, case series, and case reports. Most patients exhibited moderate-to-severe venous congestion based on their baseline VExUS scores. Higher VExUS scores correlated with a greater risk of acute kidney injury (AKI) in post-operative patients. The VExUS score strongly correlated with central venous pressure; specific components, such as the intra-renal monophasic pattern, portal-pulsatility, and inferior vena cava diameter, exhibited robust predictive value for venous congestion. Conclusion: VExUS score is valuable in assessing and predicting venous congestion, especially regarding AKI prediction risk and guiding interventions. However, its utility in predicting outcomes in acute heart failure patients appears less certain.
