Side Effects of Radiofrequency Ablation Therapy

Radiofrequency ablation, also referred to as RFA, is a procedure that can help to reduce pain caused by varicose veins. The radiofrequency waves work to produce an electrical current that heats a small area of nerve tissue. That helps to redirect pain signals from that area of the leg.

The pain relief from radiofrequency ablation therapy can last the patient from six to 12 months. For some patients, the relief from the treatment can last for several years. Over 70% of all patients treated with this form of therapy have experienced success with their pain relief.

How Does Radiofrequency Ablation Therapy Work?

Radiofrequency ablation therapy is a minimally invasive procedure used to treat various medical conditions, particularly those involving pain management or the removal of abnormal tissue growths. It employs the use of radiofrequency waves to generate heat and selectively destroy targeted tissue. The process is precise and localized, minimizing damage to surrounding healthy tissue.

The therapy works by delivering high-frequency electrical currents through a specialized needle or probe directly into the targeted area of the body. These radiofrequency waves generate heat as they pass through the tissue, causing thermal damage to the cells. This controlled destruction of tissue disrupts the nerve signals responsible for transmitting pain sensations or eliminates abnormal growths, such as tumors or abnormal heart tissue.

One of the key components of radiofrequency ablation therapy is imaging guidance, such as fluoroscopy, ultrasound, or computed tomography (CT), which allows the healthcare provider to accurately visualize the targeted area in real-time. This ensures precise placement of the needle or probe and optimal treatment outcomes.

During the procedure, local anesthesia is typically administered to numb the area being treated, reducing discomfort for the patient. Once the needle or probe is correctly positioned, the radiofrequency energy is then delivered, heating the tissue to the desired temperature range, typically between 60°C to 100°C. This elevated temperature causes coagulative necrosis, effectively destroying the targeted tissue.

The duration of the procedure can vary depending on the size and location of the targeted area. Some treatments may take only a few minutes, while others may require longer durations. Following the completion of the therapy, patients are usually monitored for a brief period before being discharged home.

Radiofrequency ablation therapy is commonly used to manage chronic pain conditions such as arthritis, spinal joint pain, and certain types of cancer pain. It is also utilized in the treatment of cardiac arrhythmias, liver tumors, and benign prostatic hyperplasia (BPH), among other conditions.

The Possible Side Effects of Ablation Therapy

Radiofrequency ablation therapy is a minimally invasive treatment process. The treatment is generally considered to be safe and low-risk. However, because it does involve injections, there is a chance that the patient may develop side effects or experience complications afterward.

Two of the most common side effects that people experience when they have RFA treatment are burning or numbness at the injection site. Some patients have reported hypersensitivity with the burning sensation and tingling if they experience any numbness at the injection site.

Some of these symptoms may feel like a sunburn at the treatment site. The symptoms are believed to last for the first few days or weeks following the procedure. Patients can also help to manage these symptoms by getting plenty of rest. They can also use an ice pack over the sore area intermittently or use topical and oral medications to reduce inflammation.

Small or large clots of blood in the vein or a deep vein can also occur following an RFA procedure. That is less likely to occur if the patient also has vein stripping surgery along with their RFA. Also, the more experience your vein expert has had with radiofrequency ablation, the less risk the patient will have of experiencing these side effects.

The side effects are generally not severe; however, the pain could become troublesome as it may last for several weeks.

Should I Be Concerned About Deep Vein Thrombosis?

RFA is a low-risk treatment option for varicose veins. There is some bruising and swelling that may occur along with discomfort. Deep Vein Thrombosis or DVT is a condition that could happen during this and other vein treatment procedures. DVT is when a clot forms in the vein. There is around a 1% risk for this complication with the procedure, but it is still good to learn more about it if you are planning to have RFA. Around half of all patients who form a DVT will develop a pulmonary embolism that causes the blood clot to travel to the lungs. It is rare but can be extremely dangerous and must be treated with blood thinners if it happens.

Suggestions for the Recovery Period

After undergoing radiofrequency ablation therapy, it's essential to properly manage your recovery to ensure optimal healing and minimize any potential discomfort. Here are some suggestions to guide you through the recovery period:

• Follow Post-Procedure Instructions: Your healthcare provider will provide specific post-procedure instructions tailored to your individual needs. It's crucial to carefully follow these guidelines to promote healing and reduce the risk of complications.

• Manage Pain and Discomfort: It's normal to experience some discomfort or pain at the treatment site following radiofrequency ablation therapy. Your healthcare provider may recommend over-the-counter pain medications or prescribe pain relievers to help manage any discomfort. Follow their recommendations closely and report any severe or persistent pain to your healthcare team.

• Monitor for Signs of Infection: Keep an eye on the treated area for any signs of infection, such as increased redness, swelling, warmth, or drainage. If you notice any of these symptoms, contact your healthcare provider immediately, as prompt treatment is essential to prevent complications.

• Apply Ice Packs: Applying ice packs to the treatment site can help reduce swelling and alleviate discomfort. Use a clean cloth to wrap the ice pack and apply it to the area for short intervals, taking breaks in between to prevent skin damage.

• Rest and Limit Activity: Give your body time to rest and recuperate following the procedure. Avoid strenuous activities or heavy lifting for the first few days after treatment, as these activities can increase discomfort and delay healing. Your healthcare provider will advise you on when it's safe to resume your normal activities.

• Stay Hydrated and Eat Nutritious Foods: Proper hydration and nutrition are essential for the healing process. Drink plenty of water and consume a balanced diet rich in fruits, vegetables, lean proteins, and whole grains to support your body's recovery.

• Follow-up with Your Healthcare Provider: Attend any scheduled follow-up appointments with your healthcare provider to monitor your progress and address any concerns or questions you may have. They may recommend additional treatments or adjustments to your recovery plan based on your individual response to therapy.

• Be Patient: Healing takes time, so be patient with yourself as you recover from radiofrequency ablation therapy. It's normal to experience ups and downs during the recovery process, but with proper care and attention, you can expect to gradually improve and resume your normal activities.

By following these suggestions and staying in close communication with your healthcare provider, you can promote a smooth and successful recovery from radiofrequency ablation therapy.
