Laser Treatment for Varicose Veins

Before undergoing endovenous laser ablation (EVLA) for varicose veins, patients typically have an initial consultation with a vascular specialist. During this consultation, the doctor reviews the patient’s medical history, performs a physical examination, and may use ultrasound imaging to evaluate the affected veins and determine the extent of venous insufficiency. The ultrasound helps map out the veins to guide the procedure. Patients are usually advised to avoid certain medications, like blood thinners, in the days leading up to the surgery. Additionally, fasting for a few hours may be required, depending on the clinic’s guidelines. The procedure is performed on an outpatient basis, so patients should arrange for someone to drive them home afterward.

On the day of the procedure, the medical team prepares the treatment area by sterilising it and administering a local anaesthetic to numb the skin and tissue around the vein. Compression stockings may also be provided, which patients will need to wear post-procedure to aid in healing and minimise swelling. Clear instructions are given regarding what to expect during and after the surgery, ensuring patients are fully prepared.

Endovenous Laser Ablation is a minimally invasive procedure performed under local anaesthetic. Before and during the procedure the vein will be monitored via ultrasound imagery.

The surgeon will make a small cut or incision in the skin through which a catheter is passed and inserted into the varicose vein. A laser fibre will then be passed through the catheter into the vein. As the catheter is slowly removed, the laser fibre will heat up the length of the vein causing it to close up and shrink.

The laser fibre targets the vein walls, causing them to heat up and collapse.

The cut where the catheter was inserted will likely be small enough that you won’t need stitches. A bandage will be put on the site and your surgeon may recommend using support stockings for recovery.

The procedure takes roughly 45 -90 minutes to perform, depending on the number of veins being treated.

After the laser surgery, most patients are able to go about their normal daily activities within a day or two, though strenuous exercise and heavy lifting should be avoided for about a week. Compression stockings must be worn for several days or weeks to support blood flow and reduce swelling. It’s common to experience mild bruising, swelling, or a sensation of tightness along the treated vein, which typically resolves within a few weeks. Over-the-counter pain relievers may be recommended if discomfort arises.

Follow-up appointments are usually scheduled within a week or two to assess the success of the procedure. During these visits, the doctor may perform an ultrasound to ensure the vein is properly sealed and there are no complications, such as blood clots. Over time, the treated vein shrinks and is naturally absorbed by the body, improving the appearance of varicose veins and alleviating symptoms like pain or heaviness. Most patients find significant relief after the procedure, but maintaining a healthy lifestyle, including regular exercise and weight management, is essential to prevent the development of new varicose veins.
