Clinical Report: Characterization of Clinical Features and Imaging Changes in HPVG

Overview

This study characterizes the clinical features, etiologies, imaging patterns, and prognostic factors of hepatic portal venous gas (HPVG) managed conservatively. Key findings indicate that hypoalbuminemia and elevated procalcitonin levels are strongly associated with mortality in conservatively treated HPVG patients.

Background

Hepatic portal venous gas (HPVG) is a rare radiologic finding that can indicate serious underlying conditions. Historically viewed as a surgical emergency, recent studies suggest that the prognosis of HPVG varies significantly based on its etiology and associated clinical features. Understanding the clinical spectrum of HPVG is crucial for guiding management decisions and improving patient outcomes.

Data Highlights

Key Findings

• HPVG was diagnosed in 16 patients, with a mean age of 61.1 years.
• The in-hospital mortality rate for conservatively managed HPVG was 62.5%.
• Major etiologies included intra-abdominal infection (31.3%) and gastrointestinal bleeding (25%).
• Non-survivors had significantly lower serum albumin and higher procalcitonin levels.
• Imaging follow-up showed complete gas resolution in several patients after managing underlying conditions.

Clinical Implications

Clinicians should consider hypoalbuminemia and elevated procalcitonin levels as significant prognostic indicators in patients with HPVG. A combined evaluation of imaging findings and biomarkers may enhance risk stratification and guide management strategies for these patients.

Conclusion

The findings underscore the importance of a nuanced approach to HPVG, emphasizing conservative management in select cases. Further multicenter studies are needed to validate these results and refine treatment protocols.
