Radiofrequency ablation (RFA) of varicose veins

It takes a while to see the benefits of the RFA procedure. Although the main vein is closed down at the time of the procedure, there is typically a period of several weeks of mild bruising and swelling and so there are usually no immediate benefits. Most patients start to see an improvement in their symptoms between 1 and 3 months after the procedure with results continuing to improve up to six months after the procedure.

Whilst the procedure is very effective at closing down the largest vessels, there are often smaller vessels that feed from the large vessels that take time to shut down or can persist after the procedure. It is normally possible to improve these smaller vessels with sclerotherapy foam injection. Most patients who have an RFA procedure will also require one or two sessions of foam sclerotherapy at a later stage to achieve optimal results. Find out more about foam sclerotherapy.

Radiofrequency ablation (RFA) for varicose veins is generally safe and effective, but like any medical procedure, it carries some potential side effects and risks. These are typically mild and temporary, but it’s important to be aware of them before undergoing the procedure.

Bruising, swelling and discomfort are common and to be expected after the procedure. Less commonly, phlebitis – or inflammation of the blood vessel – can become a problem that requires treatment with anti-inflammatory medication. Very rarely, an infection at the incision site can require additional treatment with antibiotics. Injury to nerves surrounding the blood vessel can cause temporary numbness or tingling. Deep vein thrombosis is the most serious complication, that affects approximately 1 in 100 (1%) patients.. This requires immediate medical attention to prevent it from progressing to a pulmonary embolism.

The RFA procedure is usually very effective, particularly for patients who have been properly assessed, diagnosed and had the correct treatment for their condition. However, a small percentage of patients – despite the best care and attention – will experience recurrence of the varicose veins. This is usually around 5%.

The key to achieving the best outcome when treating your varicose veins is to ensure you are treated by an experienced vascular surgery specialist that you feel you can trust and making sure you are properly assessed and have a bespoke treatment plan that you follow, including all aftercare instructions.
