Suppressing oscillatory reflux in chronic venous disease (CVD) significantly reduced inflammatory markers like Tumor Necrosis Factor-α. This suggests flow modulation is key to managing CVD inflammation and improving patient outcomes.
Area of Science:
- Vascular Surgery
- Immunology
- Biomedical Engineering
Background:
- Chronic venous disease (CVD) is associated with an inflammatory phenotype.
- The role of oscillatory reflux in CVD inflammation requires further investigation.
Purpose of the Study:
- To assess if suppressing the oscillatory component of reflux can improve the inflammatory phenotype in CVD patients.
Main Methods:
- A prospective, blinded, case-control study involving 54 CVD patients undergoing echo-color-Doppler assessment.
- Measurement of 19 inflammatory cytokines pre- and post-intervention.
- A control group of 21 unoperated CVD patients for comparison.
Main Results:
- Twenty-three patients completed the 6-month follow-up, demonstrating suppression of oscillatory venous reflux.
- Significant decreases were observed in Tumor Necrosis Factor-α (TNFα), Granulocyte Colony Stimulating Factor (G-CSF), Interferon gamma-induced Protein 10 (IP-10), and Interleukin-15 (IL-15).
- TNFα and IP-10 levels returned to physiological ranges, correlating with oscillatory flow correction.
Conclusions:
- Surgical suppression of oscillatory reflux modulates the inflammatory phenotype in CVD.
- Venous flow dynamics play a pivotal role in the inflammatory processes of CVD.
