Evaluation of A/C Ratio for Early Venous Tension Changes in Deep Vein Thrombosis: A Study of Its Diagnostic Value and Comparison to Conventional Measures

This study evaluates the use of the A/C ratio to measure early vein tension changes in DVT of the lower extremity. The study compares the cross-sectional area, cross-sectional perimeter, and A/C ratio among a normal control group, a flow reduced group, and a venous thrombosis group. The study concludes that the A/C ratio is a more stable measure of vein tension compared to conventional measures, and provides new thinking and reference for early clinical intervention in preventing DVT.

Questions:

• Can the A/C ratio be used as a diagnostic tool for DVT, or is it only useful for measuring early vein tension changes?
• How does the A/C ratio compare to other non-invasive diagnostic tools for DVT, such as D-dimer testing or venous ultrasound imaging?
• Are there any limitations to using the A/C ratio, such as difficulty in obtaining accurate measurements or variability among different patients?
