Medical Condition
Poor Vein Valve Function
When the one-way valves inside leg veins no longer close properly, blood pools and pressure rises.
Quick Facts
Common Signs
Heaviness, swelling, visible veins, skin changes
Often Related To
Reflux, CVI
First Step
Venous reflux ultrasound
Insurance
Often covered for medical evaluation and treatment when symptoms and ultrasound findings support medical necessity.
Overview
Poor vein valve function means one-way valves inside the leg veins do not close properly. This allows blood to flow backward and pool.
Common symptoms
- Heaviness
- Swelling
- Aching
- Visible veins
- Skin changes
Why it happens
Valves may weaken, stretch, or be damaged over time due to genetics, pregnancy, standing occupations, prior clots, age, or other factors.
When to seek evaluation
If you have ongoing leg symptoms suggestive of venous disease.
How we evaluate it
Venous reflux ultrasound.
Treatment options
Compression, conservative care, EVLT, RFA, VenaSeal, Varithena, and ClariVein when medically appropriate.
Damaged valves can allow backward flow and pooling, raising pressure inside the leg veins.
