Varicose Veins: Causes, Recurrence, and Treatment Options

About Varicose Veins

Hello, I would like to ask how varicose veins are caused.
My mother had varicose veins before and underwent surgery, but it seems to have recurred.
What could be the reason for this? Besides undergoing surgery again, how can we improve the situation? Thank you!

Dr. Lin Zhemin reply Surgery

Varicose veins are caused by the failure of the venous valves in the lower extremities, leading to impaired venous return.
Post-surgical recurrence can be managed with sclerotherapy or ultrasound-guided foam sclerotherapy, but lifestyle maintenance is also crucial.
Consistent practices such as elevating the legs and wearing compression stockings are important.

More Info

Varicose veins, or venous insufficiency, are a common condition characterized by enlarged, twisted veins, often occurring in the legs. They result from a combination of genetic, environmental, and lifestyle factors that lead to the weakening of the vein walls and valves. Understanding the causes, recurrence, and treatment options for varicose veins is essential for managing this condition effectively.

Causes of Varicose Veins
1. Genetics: A family history of varicose veins significantly increases the likelihood of developing the condition. If one or both parents had varicose veins, the risk is higher for their children.

2. Age: As people age, the valves in their veins can weaken, leading to improper blood flow and increased pressure in the veins.

3. Gender: Women are more likely to develop varicose veins due to hormonal changes during pregnancy, menstruation, or menopause, which can relax vein walls.

4. Obesity: Excess body weight puts additional pressure on the veins, contributing to their enlargement and dysfunction.

5. Prolonged Standing or Sitting: Occupations that require long periods of standing or sitting can hinder blood flow and increase the risk of developing varicose veins.

6. Pregnancy: The increased blood volume and hormonal changes during pregnancy can lead to the development of varicose veins. They often improve after childbirth, but some women may experience lasting changes.

Recurrence After Surgery
Surgical interventions for varicose veins, such as vein stripping or endovenous laser treatment, aim to remove or close off the affected veins. However, recurrence can occur due to several reasons:
1. Inadequate Treatment: If not all affected veins are treated, remaining veins may become varicose over time.

2. New Vein Development: The body can develop new varicose veins after surgery, especially if the underlying risk factors (like obesity or prolonged standing) are not addressed.

3. Genetic Predisposition: If there is a strong genetic component, individuals may continue to develop varicose veins despite surgical intervention.

Treatment Options Beyond Surgery
While surgery is a common treatment for varicose veins, there are several non-surgical options that can help manage symptoms and improve the condition:
1. Compression Stockings: Wearing graduated compression stockings can help improve blood flow and reduce swelling. They are often recommended as a first-line treatment.

2. Lifestyle Changes: Encouraging your mother to maintain a healthy weight, engage in regular physical activity, and avoid prolonged periods of standing or sitting can significantly improve symptoms.

3. Elevating the Legs: Elevating the legs above heart level for short periods throughout the day can help reduce swelling and discomfort.

4. Sclerotherapy: This minimally invasive procedure involves injecting a solution into the varicose veins, causing them to collapse and fade. It can be an effective option for smaller veins.

5. Endovenous Laser Treatment (EVLT): This is a less invasive procedure that uses laser energy to close off varicose veins. It can be done in an outpatient setting and has a shorter recovery time than traditional surgery.

6. Radiofrequency Ablation: Similar to EVLT, this technique uses radiofrequency energy to heat and close off varicose veins.

7. Regular Monitoring: Regular follow-ups with a healthcare provider can help monitor the condition and make timely adjustments to the treatment plan.

Conclusion
Varicose veins are a multifactorial condition that can recur after surgical treatment due to various reasons, including genetic predisposition and lifestyle factors. While surgery is an option, there are several non-invasive treatments and lifestyle modifications that can help manage symptoms and prevent recurrence. It is essential for your mother to consult with her healthcare provider to develop a comprehensive management plan tailored to her specific needs. Regular follow-ups and adherence to recommended lifestyle changes can significantly improve her quality of life and reduce the likelihood of further complications.

Hello Dr. Lin: What are the treatment options for varicose veins?
