Radiofrequency Ablation (RFA) is a relatively new technique of treating persistent venous insufficiency which provides less invasive but efficient addressing of the often widespread problem. Varicose veins present both physical and psychological discomfort as well as swelling, but RFA stands out among all other treatment options in the market for its accuracy, efficacy, and faster post-operative rehabilitation as compared to most conventional surgical procedures. In case you are planning to undergo RFA, herein is presenting a detailed picture of this novel procedure.
What is RFA?
Radiofrequency Ablation (RFA) is a procedure which is increasingly gaining popularity as a modern treatment of varicose veins by the application of heat through radiofrequency energy to close these veins. This applied microwave energy generates heat which destroys the lining of the affected varicose vein making it stick together. Eventually, such vein will be removed by the body and redistribution of the blood will occur to those veins that are healthy and intact.
RFA is commonly utilized in the management of large varicose veins, preferably in the lower extremities. The procedure is done by a vascular surgeon in place of more extensive surgeries such as vein stripping.
How Does RFA Work?
The Working:
Pre-Treatment Consultation
Prior to RFA treatment, you will meet with a vascular physician who will assess the varicose veins and see whether RFA is suitable for the individual. You may also have an ultrasound conducted so that the veins can be evaluated and the areas for treatment mapped out.
Local Anesthesia
Usually, the patient is localized to a region that requires treatment and an RFA treatment is done under local anesthesia in order to keep the patient comfortable and in the treatment area at such treatment risks being general anesthesia.
Insertion of the Catheter
This is typically done in conjunction with the treatment of the varicose veins by making a small incision in the region of the thigh or calf towards the ones to be treated. A thin catheter is then introduced through the incision into the affected vein. The position of the catheter is monitored using ultrasound to ensure it is within the vein that requires treatment.
Application of Radiofrequency
Energy When the catheter is in place, the walls of the vein to which the catheter is placed are subjected to radiofrequency energy. The heat produced by the radiofrequency energy makes the vein wall to constrict and finally close. In doing this, the vein is practically shut so that blood would scarcely be able to go through.
Catheter Removal and Bandaging
After the vein is collapsed an intervention is also done so that the catheter is removed and the site of incision is bandaged. The whole procedure usually lasts approximately 30 to 60 minutes and depends on the size and location of varicose veins addressed at that point.
What to expect after RFA
The recovery process:
- Minimal Downtime RFA has one of its appeals due to the near absence of any such recovery period. Most patients are able to live normal day today activities standard domestic duties the day after or 2 days after the procedure. However, it is advisable to refrain from excessive activities such as exertion, heavy carrying, and standing for long periods for, the first few days after the surgery allowing the treated veins first to be fortified.
- Compression Stockings For example, after the procedure your physician may advise you to wear compression stockings for several weeks. The stockings provide compression to maintain blood circulation, avoid edema and assist in the healing of the treated veins.
- Improvement in Symptoms Equal to RFA, quite a number of patients report that they feel quite an improvement in their unrealistic expectations with regards to things like pain, swelling and discomfort right after the procedure. As the treated veins are absorbed in the body, visibility of varicose veins will improve over the next few weeks.
- Follow-Up Visits Usually, your vascular specialist will schedule follow-up visits to check on your progress as well as the progression of the treated veins. It might be necessary to an ultrasound to rule out Recanalization of the veins.
Advantages of RFA for Treating Varicose Veins
Less Invasive than Traditional Surgery
RFA is a relatively simple procedure that entails making a small incision to introduce the catheter. This contributes to less scarring, lower chances of complications and shorter recovery period as opposed to conventional vein stripping surgeries.
Effective for Large Veins
RFA is especially effective in treating larger, problem veins in the legs that may be benign but cause troublesome physical symptoms and huge burdens for the people having them, like constant aching, leg swelling, heavy legs and appearance of the leg.
Rapid Recovery
Most patients who have RFA typically resume their normal activities and go to work one to two days later. RFA therefore becomes a popular choice particularly for busy people without persistent undertaking because of the short recovery time as compared to other surgical procedures.
No General Anesthesia Required
In this case, local anesthetic is used to perform the operation which contributes to having fewer complications to those associated with general anesthesia. This means, in turn, that the patient becomes a candidate for treatment, some safety.
Low Risk of Complications
The risk of complications with RFA is minimal. As it is a less invasive technique, the risk of infections, clots, and damages to the nerves is much lesser as compared to more severe surgeries.
Potential Side Effects and Risks
RFA is generally a safe procedure but some patients may have some small side effects after being treated. These side effects remain self-limiting meaning there are mild and are expected to heal:
- Extension of discoloration of the skin at the surgery site or the treated out vein
- Affected region may become Tender or mild urinary retention may be painful
- Numbness or tingling sensations may be experienced on the legs rather this is very uncommon and fades off after some period.
- Discoloration of features cosmetically unacceptable, patients might see this over the treated vein and this usually disappears with time approximately just a few weeks.
The more severe complications e.g. blood clots or rather nerve damage are very uncommon yet do happen. Therefore, patients should observe every post-procedure concern provided to avoid the risk of the complications.
Who is a Good Candidate for RFA?
RFA is appropriate for people with moderate to severe varicose veins, especially where other less invasive measures such as the compression stockings have failed. This procedure will suit the people vanity that wishes to have quickly such treatment with expected fewer traumas.
Though, RFA may not be suitable for all people. For example, patients with certain medical illnesses such as deep vein thrombosis (DVT) or patients with tiny spider veins may have other alternative options. Your vascular specialist will look into your condition and medical history further to know if RFA is suitable for you.
Conclusion
Radiofrequency Ablation (RFA) is one of the most sophisticated and successful treatments for varicose veins. It is simple to perform, requires few resources and generates results that last for long period. In case you are suffering from varicose veins which are quite painful, unpleasant or strictly cause comfort problems RFA is a great remedy even for prevention of further complications and will significantly enhance your quality of life. Don’t forget to have a talk with a vascular specialist regarding the possible pathways of treatment available for you together with the appropriateness of RFA.
