Varicose veins are enlarged, twisted veins, often in the legs, causing discomfort and aesthetic concerns. Endovenous Laser Ablation (EVLA) is an effective method for treating them. Many wonder if varicose veins reappear after treatment. This article explores EVLA and the likelihood of recurrence.
Understanding Laser Treatment for Varicose Veins
Endovenous Laser Ablation (EVLA) is a minimally invasive procedure that seals affected varicose veins. A thin laser fiber is inserted into the diseased vein, with ultrasound guidance helping position it accurately. Once positioned, the laser emits energy, which heats the vein wall, causing it to collapse and seal. This process redirects blood flow to healthier veins, reducing the appearance of varicose veins and alleviating associated symptoms. EVLA is known for its high initial success rates, often reported between 95% and 98% in effectively closing the treated vein.
Recurrence of Varicose Veins After Laser Treatment
While EVLA effectively treats existing varicose veins, the specific veins treated do not reopen. The procedure aims to permanently close the diseased vein, and once it is sealed, blood is rerouted to other healthy veins. However, the underlying condition that causes varicose veins, known as chronic venous insufficiency, is progressive. This means that new varicose veins can develop in different areas of the leg or from previously unaffected veins over time. Recurrence rates for new varicose veins after treatment can vary. This is generally considered the development of new vein issues rather than a failure of the initial EVLA procedure on the treated vein.
Factors Contributing to Recurrence
Several factors can contribute to new varicose veins after laser treatment. Genetic predisposition plays a significant role, as a family history of venous disease increases an individual’s likelihood of developing new vein issues. The natural progression of chronic venous insufficiency, which is a long-term condition, means that other vein valves may weaken over time, leading to new varicose veins.
Lifestyle factors also have an impact. Prolonged periods of standing or sitting can increase pressure in the leg veins, contributing to new vein formation. Obesity or significant weight gain places additional strain on the venous system, further elevating the risk. Hormonal changes, such as those experienced during pregnancy or menopause, can also affect vein wall elasticity and contribute to the development of new varicose veins. In some cases, if all sources of abnormal blood flow were not fully addressed during the initial treatment, or if the body forms new, weak blood vessels in response to the procedure (neovascularization), new veins can emerge.
Preventing Recurrence and Managing New Veins
To minimize new varicose veins after laser treatment, several proactive measures can be adopted. Maintaining a healthy weight through a balanced diet and regular exercise, such as walking, biking, or swimming, promotes healthy circulation and reduces pressure on the veins. Avoiding prolonged periods of standing or sitting is also beneficial; taking breaks to move around or elevate the legs can help.
Wearing compression stockings can support vein health by improving blood flow. Regular follow-up appointments with a vein specialist are important for monitoring vein health and detecting new issues early. If new varicose veins appear, various treatment options, including additional laser ablation or sclerotherapy, are available to address them.
