Biomarkers like VEGF, Fibronectin, and MMP-9 increase with Chronic Venous Disease (CVD) severity. PGP 9.5 levels decrease in later stages, indicating reduced vein wall innervation in varicose veins (VVs).
Area of Science:
- Vascular Biology
- Histopathology
- Biomarker Research
Background:
- Chronic Venous Disease (CVD) is prevalent, characterized by pathological changes in varicose veins (VVs).
- Understanding histopathological abnormalities is crucial for correlating with clinical manifestations of CVD.
Purpose of the Study:
- To correlate key histopathological abnormalities with clinical issues in Chronic Venous Disease (CVD).
- To evaluate specific biomarkers in venous tissue related to CVD severity.
Main Methods:
- Collected venous tissue from patients undergoing stab avulsion for VVs.
- Assessed biomarkers: Vascular-Endothelial Growth Factor (VEGF), Protein Gene Product 9.5 (PGP 9.5), Fibronectin (FN), and Matrix Metalloproteinase-9 (MMP-9).
- Classified CVD severity using Clinical-Etiology-Anatomy-Pathophysiology (CEAP) criteria.
Main Results:
- Biomarker expression varied across CEAP classes (C2, C3, C4).
- VEGF, Fibronectin (FN), and MMP-9 showed increasing trends from CEAP C2 to C4.
- PGP 9.5 levels decreased in CEAP C4 patients.
Conclusions:
- VEGF and FN correlate with progressive CVD severity (C2-C4).
- MMP-9 is highly expressed even in early CVD stages and increases with severity.
- Decreased PGP 9.5 in advanced stages suggests reduced vein wall innervation.

Venous Return
What is Venous Return?
Venous return refers to the rate at which blood flows back to the heart from the body's peripheral veins. It's an integral part of the circulatory system...
