What are Varicose Veins?


Varicose veins are enlarged, twisted, and bulging veins that commonly appear on the legs and feet. They occur when the valves within veins—responsible for directing blood flow toward the heart—become weak or damaged, causing blood to pool and the veins to swell.

This condition is widespread, especially among adults who stand or sit for long periods. While often seen as a cosmetic issue, varicose veins can sometimes lead to discomfort, pain, and more serious complications like venous ulcers or blood clots if left untreated.

THANC Hospital Chennai provides advanced diagnostic and treatment solutions for varicose veins, combining minimally invasive procedures with expert vascular specialists to ensure effective, safe, and lasting results.

Understanding Varicose Veins

Varicose veins are a result of increased pressure within the veins of the lower limbs. Normally, veins carry blood back to the heart with the help of one-way valves that prevent backflow. When these valves weaken, blood collects in the veins, causing them to dilate and appear prominently beneath the skin.

Causes and Risk Factors

Several factors contribute to the development of varicose veins:

  • Genetic predisposition: A family history of vein problems increases risk.
  • Prolonged standing or sitting: Occupations requiring long hours on feet or at a desk lead to poor circulation.
  • Age: The risk rises with aging as vein elasticity decreases.
  • Gender: Women are more likely to develop varicose veins due to hormonal changes during pregnancy or menopause.
  • Pregnancy: Increased blood volume and pressure on leg veins contribute to their formation.
  • Obesity: Excess body weight increases pressure on veins.
  • Hormonal factors: Use of birth control pills or hormone therapy may influence vein wall strength.
  • Previous leg injury or blood clot: Can damage valves and restrict normal blood flow.

Who is Affected?

Varicose veins are prevalent among middle-aged and older adults. People who stand for long hours (such as teachers, healthcare workers, or retail employees), pregnant women, and individuals with sedentary lifestyles are particularly at risk. Though more common in women, men can also develop the condition due to similar risk factors.

Common Symptoms of Varicose Veins

Varicose veins develop gradually and can cause both visible and physical symptoms depending on severity.

Key Symptoms

  • Blue or purple twisted veins visible under the skin
  • Swelling in legs, ankles, or feet
  • Heaviness or aching sensation, especially after standing
  • Burning, throbbing, or muscle cramps at night
  • Dry, itchy, or discolored skin around affected veins
  • In severe cases, skin ulcers near the ankles

These symptoms may worsen after prolonged standing, during hot weather, or by the end of the day.

When to Seek Medical Help

While mild cases can be managed with lifestyle changes, it is important to seek medical evaluation if you notice:

  • Persistent pain, swelling, or skin discoloration
  • Open sores or ulcers on the legs
  • Bleeding from varicose veins
  • Sudden swelling in one leg (may indicate a clot)

Early consultation ensures timely treatment and helps prevent complications like chronic venous insufficiency or deep vein thrombosis (DVT).

Diagnosis of Varicose Veins

Diagnosing varicose veins involves a physical examination and imaging studies to assess vein function and identify underlying venous disorders.

Diagnostic Methods

  • Physical Examination: The doctor evaluates visible veins, swelling, and symptoms while the patient stands.
  • Duplex Ultrasound: The most accurate test for varicose veins, it uses sound waves to visualize blood flow and valve performance.
  • Venography (rarely used): Involves injecting dye into veins to obtain detailed X-ray images if deeper vein issues are suspected.
  • Venous Doppler Scan: Assesses the direction and speed of blood flow.

THANC Hospital Chennai utilizes advanced vascular imaging technology and a dedicated vascular care team to provide precise diagnosis and customized treatment plans for every patient.

Treatment Options for Varicose Veins

The goal of treatment is to reduce discomfort, improve circulation, and prevent further complications. Modern therapies are highly effective, minimally invasive, and require little recovery time.

Non-surgical / Medical Treatments

  1. Compression Therapy:
     Specially designed compression stockings improve blood flow and reduce swelling by applying gentle pressure to the legs.
  2. Medications:
     Anti-inflammatory drugs may relieve pain and swelling. In some cases, medications are prescribed to strengthen vein walls and prevent clotting.
  3. Lifestyle Modifications:
    • Maintain a healthy body weight.
    • Elevate legs periodically to improve circulation.
    • Avoid long periods of sitting or standing.
    • Engage in regular exercise like walking or swimming.
    • Limit salt intake and stay hydrated.
  4. Sclerotherapy:
     A non-surgical procedure where a chemical solution is injected into small varicose veins, causing them to collapse and fade over time.

Surgical / Advanced Treatments

When non-surgical options are insufficient, minimally invasive procedures are used to close or remove affected veins.

  1. Endovenous Laser Treatment (EVLT):
     A laser fiber is inserted into the vein to seal it shut using heat energy. This is performed under local anesthesia and offers quick recovery.
  2. Radiofrequency Ablation (RFA):
     Similar to EVLT but uses radiofrequency energy to close off damaged veins.
  3. Ambulatory Phlebectomy:
     Small incisions are made to remove superficial veins under local anesthesia, leaving minimal scarring.
  4. Endoscopic Vein Surgery:
     Used in severe cases with leg ulcers; a small camera guides precise removal or closure of problematic veins.
  5. VenaSeal™ Closure System:
     A modern technique that uses a medical adhesive to seal the affected vein—no heat, anesthesia, or compression stockings required post-procedure.

The vascular surgery department at THANC Hospital Chennai offers all these advanced treatments, ensuring safe, painless, and long-lasting results tailored to individual needs.

Prevention & Lifestyle Tips

Preventing varicose veins or slowing their progression involves adopting a healthy lifestyle and proper circulation practices.

Practical Steps for Prevention and Risk Reduction

  • Exercise regularly: Walking, swimming, and yoga strengthen calf muscles and promote healthy blood flow.
  • Maintain healthy body weight: Reduces stress on leg veins.
  • Avoid standing or sitting for long periods: Take short walks or stretch frequently.
  • Elevate your legs: Raise legs above heart level for 15 minutes several times a day.
  • Wear comfortable clothing: Avoid tight waistbands or high heels that restrict blood flow.
  • Follow a balanced diet: Include fiber-rich foods to prevent constipation and avoid excessive salt to reduce swelling.

Implementing these changes not only helps in preventing varicose veins but also supports overall vascular and cardiovascular health.
