The Primary Mechanism: Venous Insufficiency
To truly understand what causes varicose nervure, you need to cognise about continuing venous deficiency (CVI). Normally, your veins have one-way valves that continue blood moving upwards toward the heart. When these valves weaken or get damaged, rip can flow backward and amass. This pooling stretches the vena walls, take to the characteristic bulging appearing. Over clip, the vein loses its elasticity and becomes varicose.
Key Factors That Weaken Vein Valves
Several biologic and lifestyle factors lend to valve dysfunction. Here are the most common:

Comparing Varicose Veins vs. Spider Veins
| Lineament | Varicose Veins | Wanderer Veins (Telangiectasias) |
|---|---|---|
| Sizing | Tumid, pouch, > 3mm diam | Small-scale, thread-like, < 1mm |
| Appearance | Twisted, rope-like, often raised | Flat, red, downcast, or purplish web form |
| Primary drive | Valve failure and venous insufficiency | Capillary dilatation; often hormonal or sun harm |
| Symptoms | Pain, heaviness, tumefy, skin changes | Ordinarily symptomless; casual itch |
| Treatment approaching | Compression, laser, sclerotherapy, or | Cosmetic laser or sclerotherapy rarely needed for symptoms |
Wanderer veins are not the same as varicose vena, but they portion some hazard ingredient. See the note helps in select appropriate intervention.

Common CEAP Grades
- C0 - No visible signs
- C1 - Spider vein
- C2 - Varicose veins
- C3 - Edema (swelling)
- C4 - Skin changes (pigmentation, eczema, lipodermatosclerosis)
- C5 - Healed ulcer
- C6 - Active venous ulceration
These grades guide treatment intensity. Early-stage varicose vena (C2) often answer well to lifestyle modifications and contraction, while innovative phase require intercession.
Treatment Options: From Self-Care to Medical Procedures

- Radiofrequency extirpation (RFA) - Heat energy collapses the nervure.
- Sclerotherapy - A chemical answer is inject to scar the nervure shut.
- Phlebectomy - Pocket-size section to remove surface varicose vein.
