Varicose Veins

Symptoms & Causes
Varicose veins are swollen, twisted veins visible just under the surface of the skin, most commonly in the legs. They can range from a cosmetic issue to a condition that causes significant discomfort or complications if left untreated.
Common Symptoms
Heaviness or aching in the legs
Swelling, especially around the ankles
Cramps or throbbing at night
Skin discoloration or dryness
Bulging, rope-like blue or purple veins
Common Causes
Weak or damaged valves in the veins
Prolonged standing or sitting (occupational risk)
Hormonal changes such as pregnancy or menopause
Obesity or inactivity
Aging and family history
Note: Early symptoms may be subtle. If you experience discomfort or visible changes in your veins, consult a vein specialist promptly.

Diagnosis & Treatment
Early diagnosis of varicose veins is essential to prevent complications such as skin changes, ulcers, or deep vein thrombosis. At CHIVA Centers, a detailed evaluation helps guide the most appropriate treatment approach.
Common Diagnosis Methods
Physical examination – Assessing visible veins, swelling, and skin changes
Duplex ultrasound – Imaging to evaluate blood flow and detect valve insufficiency
Vein mapping – Locating reflux points and abnormal branches
Symptom scoring – Evaluating pain, heaviness, and impact on daily life
Treatment Options
Lifestyle changes – Elevating legs, regular exercise, weight management
Compression therapy – Medical-grade stockings to support venous return
Sclerotherapy – Injection of a solution to collapse small veins
Thermal ablation – Laser (EVLA) or radiofrequency (RFA) to seal faulty veins
CHIVA – A conservative, vein-preserving technique tailored to venous flow patterns
