What is radiofrequency ablation (RFA)?
If you’re struggling with the discomfort, swelling, or unsightly appearance of varicose veins, Radiofrequency Ablation (RFA) could be the solution you’ve been looking for. This minimally invasive procedure uses radiofrequency energy to target and close off problematic veins, providing long-lasting relief with less discomfort and downtime than traditional surgery.
In this guide, we’ll explore everything you need to know about RFA – from how it works to what you can expect during the procedure, what the recovery is, and the benefits it offers over other treatment options and the benefits some newer treatments like VenaSeal™ might have over RFA. Ultimately, there are lots of choices when it comes to treating varicose veins.
How does radiofrequency ablation (RFA) work?
RFA is a minimally invasive medical procedure used to treat varicose veins by using radiofrequency energy to heat and close off the affected veins. It is part of a group of techniques referred to as ‘endovascular’ procedures because they involve operating inside the vein rather than outside of it in the traditional approach. RFA involves inserting a small catheter into the vein, where radiofrequency energy is delivered, causing the vein walls to contract, collapse, and eventually be absorbed by the body.
How long has radiofrequency ablation (RFA) been used for treating varicose veins
RFA was introduced in the late 1990s and early 2000s as an alternative to more invasive surgical treatments like vein stripping. Around the same time, another option known as endovenous laser ablation (EVLA) was also developed.
EVLA employs a very similar technique by delivering heat to destroy the inside of the problematic blood vessels, although it uses laser energy to deliver the heat. Both RFA and EVLA are similarly very effective, although RFA is associated with fewer side effects and is generally considered to be the superior method.

What is involved in having the RFA procedure?
Before: Before the procedure, you’ll first have a consultation with a specialist vascular surgeon who will assess your varicose veins from taking a medical history, performing a thorough examination and an ultrasound scan to assess the anatomy of your veins. This helps determine the best veins to treat and ensures that RFA is the right option for you. On the day of the procedure, you’ll be asked to wear loose-fitting clothing and underwear that you don’t mind getting antiseptic on. You will be asked to sign an informed consent form before you go into the treatment room (a copy of this will be emailed to you in advance so you have plenty of time to read before you sign).
During: The procedure begins with the patient lying down on the treatment table and the affected leg is then cleaned and sterile drapes are applied. The doctor then makes a small incision near the knee or lower leg to insert a thin catheter into the problematic vein, guided by ultrasound imaging for precise placement. The doctor then injects a high volume of dilute anaesthetic – known as tumescent anaesthetic – along the length of the vein to be treated. As well as providing anaesthesia, this also helps to absorb the heat that is delivered to the vein during the procedure and reduces the chances of injuring surrounding tissues, like nerves. The catheter position is then rechecked and radiofrequency energy is delivered through the catheter, heating the vein walls and causing them to collapse and seal shut. This process is repeated along the length of the vein, effectively closing it off. The procedure typically takes about 30 to 60 minutes.
After: After the RFA procedure, a compression bandage or stocking is applied to the treated leg to help reduce swelling and promote healing. Most patients can stand up and walk immediately after the procedure, which is encouraged to help circulation. You may experience some discomfort, bruising, or swelling, but these symptoms usually subside within a few days. It’s generally recommended to avoid strenuous activities for about a week, but most people can return to their normal routines within a day or two. We will arrange to see you back in the clinic to assess the results, typically a few months after treatment since this is how long it takes for the veins to be reabsorbed by the body and for us to be able to assess the outcome.
The benefit of endovascular treatment with Radiofrequency Ablation (RFA) over traditional surgery
Endovascular treatment with RFA offers significant benefits over traditional surgery for treating varicose veins.
One of the main advantages is its minimally invasive nature, which involves only a small incision and causes far less trauma to the surrounding tissues compared to traditional vein-stripping surgery. This leads to a quicker recovery time, allowing patients to return to their normal activities, often within a day or two, as opposed to the longer downtime required after surgery. RFA also typically results in less pain, bruising, and scarring, which improves patient satisfaction both during and after the procedure.
Additionally, because RFA uses radiofrequency energy to precisely target and close off the affected veins, it reduces the risk of complications such as nerve damage, which can be more common in traditional surgical approaches. Not everyone is suitable for RFA – which is why your initial consultation and ultrasound scan assessment are so important to make sure you get the best treatment option for your particular condition.
Are there any newer, better alternatives to Radiofrequency Ablation (RFA)?
VenaSeal™ is a more recent innovative and effective option for the endovascular treatment of varicose veins, gaining FDA approval in 2015. VenaSeal™ uses a medical adhesive instead of heat to close off problematic veins.
The procedure involves inserting a small catheter into the vein and applying the adhesive, which bonds the vein walls together, causing the vein to seal shut and be gradually absorbed by the body. Compared to RFA, VenaSeal™ offers several advantages: it requires no heat or tumescent anaesthetic injections, which can reduce discomfort and eliminate the need for compression stockings after the procedure.
Additionally, VenaSeal™ has an even quicker recovery time – often allowing patients to resume normal activities almost immediately. While RFA remains a highly effective treatment with a proven track record, VenaSeal™ offers the same levels of effectiveness with less pain, inconvenience and downtime which is why it now accounts for around 50% of varicose vein treatment in the USA.
We are the first clinic in Scotland to introduce what is now considered to be the gold standard treatment for varicose veins.

Here she is… the one we’ve all been waiting for!
Lorraine, our incredible Assistant Manager, was the very first patient to have The Quantum Lift.
She’s now approaching 12 weeks after her procedure - the point at which we really start to see the result mature - and she is absolutely over the moon with her new jawline.
It’s been especially exciting watching this result develop because Lorraine was patient number one and I think you’ll agree, she set the bar pretty high.
What do you think of her result?
This is not a facelift.
This patient is just one week after The Quantum Lift, immediately after having her tape removed - you can still see a little residual adhesive on her cheeks.
The Quantum Lift is our new minimally invasive approach to rejuvenating the lower face and neck. We first use precision liposuction to remove excess fat from beneath the chin and around the jowls, sculpting a cleaner jawline. We then use QuantumRF beneath the skin to contract and tighten the tissues of the lower face and neck.
What has impressed me most about QuantumRF is the degree of tissue contraction we can achieve. You can actually see the tissues tightening during the procedure itself, but that`s only the beginning. Most patients are through the main recovery within a week or two, while tightening and collagen remodelling continue for 3–6 months afterwards.
So, at only one week, this is still a very early result but she`s already delighted with the improvement.
No facelift. One week post-treatment. And plenty more improvement still to come.
What do you think?
Dr Rhona is back!
We’re delighted to share that Dr Rhona Cameron will be returning to clinic at the beginning of September following her maternity leave and her diary is now open for appointments!
We know many of you have been looking forward to seeing Rhona again, and we’re so pleased to welcome her back!
If you’d like to book an appointment with Dr Rhona, you can do so via our website or app, or contact the team on 0141 370 0509.
We’ve shown you lots of side profiles from the Quantum Lift, but what does it look like from the front?
This lovely patient is just four weeks after her procedure, and I think the front view really shows how much we can change while still keeping the face looking soft and natural.
As part of her Quantum Lift, we removed unwanted fat from beneath the chin and around the jowls. Rather than simply discarding that fat, we used some of it to restore volume to her chin and jawline, helping to replace some of the volume she had lost over time and bring back a little of the youthful softness to the lower face.
You’ll also notice a small amount of lumpiness beneath the chin. At four weeks, this is very common after liposuction in this area and is part of the healing process. She’s now using firmer massage to help soften this over the coming weeks, and we would expect the result to continue settling and refining.
Most importantly, she’s absolutely over the moon with the change, and we are too!
What do you think of the front view?
Once again, the combination treatment wins the day!
This patient came to us hating her neck and jowls, but she would not consider anything invasive. Treating the neck is always a challenge especially with non-invasive treatments only.
For this patient we first of all reduced the fat under the chin using CoolSculpting, then we did some hyaluronic acid under the mandible to define the jaw and finally we did some Sofwave to tighten the skin.
The patient is over the moon with her results. What do you think?
There is no single "best" facial rejuvenation treatment - only the treatment that`s right for the individual patient.
For patients with more advanced facial ageing, significant jowls and loose skin of the neck, a deep plane facelift remains the gold standard. In the right hands, it can achieve results that more significant than what we can do with less invasive treatments.
This is one of our recent patients following deep plane face and neck lift surgery, performed by the incredibly talented @bramhallplasticsurgery. It`s always a privilege to work alongside Russell and see the exceptional results he consistently achieves.
One of the things I`m most proud of at McKeown Medical is that we`re a genuinely multidisciplinary team. We don`t believe every patient needs fillers. We don`t believe every patient needs surgery either. We offer injectables, lasers, minimally invasive procedures like the Quantum Lift, and facelift surgery because different patients, at different stages of the ageing process, need different solutions.
Our job isn`t to sell you a procedure - its to help you choose the right one.
If you want to have a conversation about which option is right for you, you can send us some pics by PM.

I genuinely think the Quantum Lift is changing what is possible for patients who want to improve their jawline and neck, but do not want to undergo facelift surgery.
I have used earlier generations of skin-tightening technology and, honestly, I was often underwhelmed by the results. This is different.
By combining precise power-assisted liposuction, targeted treatment of the neck muscle where needed, and QuantumRF skin tightening, we can address the three things that most commonly age the lower face and neck: muscle, fat and skin.
This patient is shown just 24 hours after treatment. There is still swelling to settle, but the early change in her jawline and neck contour is already clear.
I have also included clips from the procedure for anyone who likes seeing the technical side of what we do.
Would you consider a minimally invasive alternative to facelift surgery for your jawline or neck, or would you rather go straight to surgery?
And this is why we LOVE combination treatments in the clinic!
Different parts of the face age in different ways. And even different layers of the same part sometimes age differently, which is why we often need to combine treatments to achieve the best overall effect for each patient.
This lovely patient first underwent some laser resurfacing to her eyelid area to take away the lines and wrinkles and tighten the skin. Then we used some HA to blend the contour below the eye and cheek. Finally, we addressed the lower part of the face and neck with some Sofwave to tighten the skin and Sculptra to give her more connective tissue support.
She is over the moon with her improvement. What do you think?
The biggest mistake I see after weight loss? People choose a treatment before understanding what`s actually causing their loose skin.
Not all "loose skin" is the same, which is why the right treatment for one person can be completely wrong for another.
If you`ve lost weight and aren`t sure which option is right for you, the first step isn`t choosing a device. It`s getting the right diagnosis.
