Varicose Veins: Causes, Symptoms, Treatment Options and Surgical Solutions

by admin-blog-kh | January 13, 2017 4:38 am

Varicose veins are a common vascular condition that affects millions of people worldwide, particularly as they age. While many people view them as a cosmetic concern, varicose veins can cause significant discomfort, affect mobility, and lead to serious complications if left untreated.

Advances in vascular medicine have made it possible to effectively manage and treat varicose veins through lifestyle modifications, minimally invasive procedures, and surgical interventions. Understanding the condition and seeking timely treatment can help prevent complications and improve overall quality of life.

What Are Varicose Veins?

Veins are responsible for carrying blood from different parts of the body back to the heart. In the legs, blood must travel against gravity, which is aided by the contraction of calf muscles and one-way valves within the veins.

When these valves become weak or damaged, blood can flow backwards and collect within the veins. This causes the veins to enlarge, become twisted, and appear blue or dark purple beneath the skin. These enlarged veins are known as varicose veins.

Varicose veins most commonly occur in the legs and feet[1], although smaller forms known as spider veins may also appear elsewhere on the body.

What Causes Varicose Veins?

Several factors can increase the risk of developing varicose veins.

Ageing

As people age, vein walls and valves naturally lose strength and elasticity, increasing the likelihood of blood pooling within the veins.

Family History

Genetics plays a major role. Individuals with a family history of varicose veins have a higher risk of developing the condition.

Hormonal Changes

Women are more susceptible due to hormonal fluctuations during pregnancy, menopause, and the use of birth control pills or hormone replacement therapy.

Prolonged Standing or Sitting

Jobs that involve long periods of standing or sitting can increase pressure within the leg veins and impair circulation.

Obesity

Excess body weight places additional strain on the veins and can contribute to valve dysfunction.

Leg Injury or Trauma

Previous injuries can damage veins and affect normal blood flow.

Tight Clothing

Very tight clothing around the waist, groin, or legs may restrict circulation and contribute to venous problems.

Symptoms of Varicose Veins

Symptoms can range from mild discomfort to significant impairment of daily activities.

Common symptoms include:

• Visible blue, purple, or bulging veins
• Aching or heavy legs
• Swelling of the legs and ankles
• Burning or throbbing sensations
• Muscle cramps, especially at night
• Itching around the veins
• Leg fatigue
• Skin discoloration around the ankles
• Symptoms that worsen after prolonged standing or sitting

Can Varicose Veins Cause Knee Pain?

Varicose veins and knee pain may seem unrelated, but they can often occur together.

Poor blood circulation caused by varicose veins can result in fluid accumulation and swelling in the lower limbs. This swelling may increase pressure around the knee joint, aggravating existing knee pain and reducing mobility.

Research has also identified a relationship between chronic venous insufficiency and osteoarthritis. Venous congestion around the joint can contribute to damage of cartilage and bone structures, a condition sometimes referred to as Phleboarthrosis.

Patients experiencing both conditions may notice:

• Increased knee stiffness
• Joint swelling
• Difficulty walking
• Pain while climbing stairs
• Reduced mobility

In many cases, treating varicose veins may help alleviate some knee-related symptoms.

Complications of Untreated Varicose Veins

Although varicose veins may initially seem harmless, untreated disease can progress and lead to complications such as:

• Chronic leg swelling
• Skin pigmentation changes
• Venous eczema
• Bleeding from affected veins
• Venous ulcers
• Superficial thrombophlebitis
• Deep Vein Thrombosis (DVT)[3]
• Reduced mobility and quality of life

Early diagnosis and treatment can help prevent these complications.

How Are Varicose Veins Diagnosed?

A vascular surgeon typically performs a detailed clinical examination[4] and may recommend investigations such as:

Duplex Ultrasound Scan

This non-invasive test uses sound waves to evaluate blood flow and identify damaged valves, blocked veins, or abnormal blood pooling. It is considered the gold standard for diagnosing varicose vein disease and planning treatment.

Lifestyle Measures to Manage Varicose Veins

For mild cases, lifestyle modifications can help improve symptoms and slow disease progression.

Stay Active

Regular walking and low-impact exercises improve circulation and strengthen calf muscles, which help pump blood back to the heart.

Maintain a Healthy Weight

Weight management reduces pressure on both the veins and joints.

Elevate Your Legs

Raising the legs above heart level when resting can reduce swelling and improve blood flow.

Avoid Prolonged Standing or Sitting

Frequent movement prevents blood from pooling in the legs.

Wear Compression Stockings

Compression stockings apply graduated pressure to improve circulation, reduce swelling, and alleviate symptoms.

Non-Surgical Treatment Options for Varicose Veins

If lifestyle changes do not provide adequate relief, several minimally invasive treatment options are available.

Sclerotherapy

A special solution is injected into the affected vein, causing it to collapse and gradually disappear as the body absorbs it.

This treatment is particularly effective for small varicose veins and spider veins.

Foam Sclerotherapy

A foam-based solution is used to treat larger veins by sealing them more effectively.

Laser Treatment

Laser energy is applied to close smaller varicose veins and spider veins without the need for injections or incisions.

Benefits of Minimally Invasive Treatments

• Minimal discomfort
• Outpatient procedures
• No major incisions
• Faster recovery
• Improved cosmetic appearance

When Is Varicose Vein Surgery Required?

While many patients benefit from non-surgical treatments, surgery may be recommended when:

• Symptoms are severe or persistent
• Varicose veins significantly affect daily activities
• Leg swelling is substantial
• Skin ulcers have developed
• Bleeding occurs from varicose veins
• Blood clots form within affected veins
• Conservative treatments fail to provide relief
• Chronic venous insufficiency is present

The decision depends on the severity of the disease, ultrasound findings, and the patient’s overall health.

Surgical Treatment Options for Varicose Veins

Modern vascular surgery offers several effective treatment options with excellent outcomes[6].

Endovenous Laser Treatment (EVLT)

EVLT is one of the most commonly performed procedures for varicose veins today.

A thin laser fibre is inserted into the affected vein through a small puncture. Laser energy is then used to seal the vein from within. Blood is naturally redirected through healthy veins.

Advantages of EVLT

• Minimally invasive
• Performed under local anaesthesia
• Minimal scarring
• Reduced pain
• Quick recovery
• Same-day discharge

Radiofrequency Ablation (RFA)

RFA uses radiofrequency-generated heat to close diseased veins[7].

The procedure is similar to EVLT and offers excellent long-term results.

Advantages of RFA

• Minimal discomfort
• Faster recovery
• Excellent cosmetic outcomes
• Reduced postoperative pain

High Ligation and Vein Stripping

This traditional surgery involves tying off and removing the damaged vein through small incisions.

Although less commonly required today, it remains an effective option for extensive or complex varicose vein disease.

Ambulatory Phlebectomy

Surface varicose veins are removed through tiny punctures in the skin.

This procedure is often combined with other treatments for optimal results.

Endoscopic Vein Surgery

For advanced cases involving venous ulcers or severe vein disease, a tiny camera is inserted through small incisions to identify and treat affected veins.

What Happens During Varicose Vein Surgery?

Most modern procedures are performed as day-care surgeries.

Typically:

1. The leg is cleaned and prepared.
2. Local or regional anaesthesia is administered.
3. The surgeon inserts a catheter, laser fibre, or surgical instruments through small incisions.
4. The affected vein is closed or removed.
5. Compression bandages or stockings are applied.

Most procedures take between 30 minutes and one hour.

Recovery After Varicose Vein Surgery

Recovery is generally quick, particularly after minimally invasive procedures.

Patients are usually encouraged to:

• Walk shortly after the procedure
• Wear compression stockings as advised
• Avoid prolonged standing initially
• Stay physically active
• Attend scheduled follow-up visits

Most individuals return to normal activities within a few days, although recovery may be longer after traditional surgery.

Benefits of Varicose Vein Surgery

Successful treatment can provide:

• Relief from pain and heaviness
• Reduced swelling
• Improved circulation
• Better mobility
• Faster healing of venous ulcers
• Reduced risk of complications
• Improved appearance of the legs
• Enhanced quality of life

Risks and Side Effects of Treatment

Most procedures are safe and well tolerated. However, potential side effects may include:

• Bruising
• Temporary skin discoloration
• Mild pain or tenderness
• Small skin sores
• Temporary numbness
• Infection
• Blood clots (rare)
• Recurrence of varicose veins

Seek immediate medical attention if you experience:

• Severe swelling or redness
• Chest pain
• Shortness of breath
• Dizziness
• Coughing up blood

Can Varicose Veins Return After Treatment?

Treatment removes or closes diseased veins, but it cannot completely prevent new varicose veins from developing later in life.

Maintaining a healthy lifestyle, exercising regularly, managing weight, and following your doctor’s recommendations can help reduce the risk of recurrence.

When Should You Consult a Vascular Surgeon?

You should seek medical advice if you experience:

• Persistent leg pain or heaviness
• Swelling that does not improve
• Skin discoloration
• Leg ulcers
• Bleeding from veins
• Visible worsening of varicose veins
• Knee pain associated with chronic leg swelling
• Symptoms affecting your daily activities

Early treatment often leads to better outcomes and helps prevent complications.

Living Well with Varicose Veins

Varicose veins can affect comfort, mobility, confidence, and overall health. Fortunately, effective treatment options are available today, ranging from lifestyle modifications and minimally invasive procedures to advanced surgical interventions.

Seeking timely medical attention can relieve symptoms, improve circulation, reduce complications, and help you maintain an active and healthy lifestyle.
