Summary
Common femoral vein (SV) volume flow measured by duplex-sonography correlates with venous disease severity. Elevated SV levels indicate more severe varicosis, distinguishing it from healthy individuals.
Area of Science:
- Vascular Medicine
- Medical Imaging
- Hemodynamics
Background:
- Venous hemodynamics in the leg are crucial for assessing venous disease.
- Common femoral vein (SV) volume flow is a key hemodynamic parameter.
- Duplex-sonography is a standard method for measuring SV.
Purpose of the Study:
- To investigate the correlation between SV volume flow and the clinical grade of venous disease.
- To determine if SV measurements can differentiate between various stages of varicosis.
- To establish SV as a reliable indicator of venous insufficiency.
Main Methods:
- SV was measured in 36 patients with complete varicosis (62 limbs), 18 patients with incomplete varicosis (24 limbs), and 40 healthy individuals (78 limbs).
- Measurements were performed using duplex-sonography under standardized conditions.
- SV data was analyzed and compared across the three groups.
Main Results:
- A significant difference in SV values was observed between healthy individuals, incomplete varicosis, and complete varicosis groups.
- SV values were significantly elevated in limbs with varicosis compared to healthy limbs.
- Mean SV was 0.38 l/min in complete varicosis, 0.26 l/min in incomplete varicosis, and 0.13 l/min in healthy limbs, remaining stable over 30 minutes.
Conclusions:
- The study demonstrates a significant correlation between SV volume flow measurements and the clinical grade of venous disease.
- Duplex-sonography measurement of SV is a valuable tool for assessing venous hemodynamics and disease severity.
- Elevated SV levels are indicative of more severe venous disease, particularly varicosis.
