Endovenous Laser Ablation (EVLA) and Sclerotherapy
Endovenous Laser Ablation (EVLA)
Endovenous Laser Ablation (EVLA) is a minimally invasive procedure used to treat varicose veins by using laser energy to seal the affected veins.
Procedure:
Preparation: Before the procedure, the patient's medical history is reviewed, and diagnostic tests such as ultrasound may be conducted to assess the condition of the veins.
Anesthesia: EVLA is typically done under local anesthesia. This means that the patient is awake but the area around the vein is numbed.
The Procedure: A thin laser fiber is inserted into the affected vein through a small incision, usually near the knee. The laser emits energy, which heats and closes the vein. The procedure is guided by ultrasound imaging to ensure precision.
Benefits:
Minimally Invasive: EVLA is less invasive than traditional vein-stripping surgery.
Quicker Recovery: Patients often experience a faster recovery time compared to traditional surgery.
Reduced Pain and Bruising: Since the procedure is minimally invasive, there is typically less pain and bruising compared to traditional surgery.
Aftercare:
Compression Stockings: Patients are often advised to wear compression stockings to promote blood circulation and reduce swelling.
Activity: Most people can resume normal activities shortly after the procedure, but strenuous exercise may be restricted for a short period.
Results:
EVLA is effective in closing off varicose veins, redirecting blood flow to healthier veins.
Improvements in symptoms such as pain, swelling, and the appearance of varicose veins are often observed.
Risks and Complications:
Complications are generally rare but can include infection, nerve damage, or deep vein thrombosis. It's important to discuss potential risks with your healthcare provider.
Follow-Up:
Follow-up appointments may be scheduled to monitor the healing process and address any concerns.
Sclerotherapy
Sclerotherapy is another common and effective treatment for varicose veins, and it is often used for smaller veins, known as spider veins, as well. Here's an overview of sclerotherapy:
Procedure:
Injection of Sclerosing Agent: During the procedure, a healthcare provider injects a solution, typically a sclerosing agent, directly into the affected veins. This solution irritates the lining of the veins, causing them to collapse and stick together.
Sclerosing Agents:
Common agents used include polidocanol, sodium tetradecyl sulfate, and hypertonic saline.
Foam Sclerotherapy: In some cases, the sclerosing agent may be mixed with air to create a foam, which can be more effective for larger veins.
Treatment Session:
Duration: A session of sclerotherapy usually takes about 15-30 minutes, depending on the number and size of veins being treated.
Number of Sessions: Multiple sessions may be required to achieve the desired results.
Aftercare:
Compression Stockings: Similar to EVLA, patients are often advised to wear compression stockings to promote blood circulation and reduce swelling.
Walking: Walking is encouraged to prevent blood clots and improve circulation.
Results:
Gradual Improvement: The treated veins usually fade over several weeks as the body naturally absorbs them.
Effectiveness: Sclerotherapy is particularly effective for smaller varicose veins and spider veins.
Risks and Side Effects:
Common side effects: Temporary bruising, redness, or swelling at the injection site.
Rare complications: Allergic reactions, ulceration, or changes in skin color. Serious complications are rare.
Follow-Up:
Follow-up appointments: Patients may be scheduled for follow-up appointments to assess the treatment's effectiveness and address any concerns.
It's important to consult with a qualified healthcare professional to determine the most suitable treatment for your specific condition. The choice between EVLA and sclerotherapy, or other treatments, may depend on factors such as the size and location of the veins, overall health, and individual preferences. Always discuss the potential risks and benefits with your healthcare provider.
