RF Vein Treatment
The RF procedure, or “RF” for short, was approved by the United States Food and Drug Administration (FDA) in 1999. It’s undergone several refinements since then and is now the standard RF vein treatment for lower extremity vein disease (venous reflux). At present the procedure can be done in-office by most general surgeons, vascular surgeons, and phlebologists. The Venefit system by Covidien Medical is arguably the most widely used RF closure technique in use today.
As mentioned, the process itself typically lasts less than one hour. To start, the patient is gowned and the leg being treated is sterilized. Then a Registered Vascular Technologist (RVT), aka ultrasound tech, assists the surgeon in finding the location of the diseased vein.
Since RF Vein Treatment is heat-based it has the potential to damage surrounding tissue. To work around this problem, as well as to provide pain control, large amounts of highly diluted anesthetic fluid into the space surrounding the vein. For many surgeons, lidocaine is the anesthetic of choice. This is accomplished using a standard surgical pump. Not only does this fluid barrier protect the surrounding tissue but it provides pain control as well. Patients typically feel a pressure sensation but never outright pain or discomfort.
Next, the surgeon makes a tiny incision to access the vein. This is usually done at or near the ankle in order to treat the entire length of the diseased vein. With the RVT’s help, the surgeon inserts a specialized catheter up the length of this vein. What makes this piece of disposable medical device unique is its tip, which contains a heating element.
Note that only at this point does the actual RF Vein Treatment begin—everything up to this point has been preparation. Radiofrequency (RF) energy is then delivered through this catheter to the element to produce heat. This delivers very high temperature spikes for very short periods of time. This damages the vein enough to cause the formation of scar tissue. As the catheter is withdrawn each segment is treated, one at a time, along the course of the vein. This treatment phase takes under 5 minutes.
As the vein scars down it collapses. Finally, in the months following the procedure it is broken down by the body. Eventually the vein is reabsorbed entirely.
Benefits Of RFA
1. Quick and secure
The typical time for an outpatient RFA procedure is 35 to 40 minutes. The procedure’s non-surgical nature eliminates the hazards associated with surgery.
2. minimally harmful
RFA may treat an entire vein up to 30 inches in length with just a short, 14 inch incision.
3. Almost no pain
You shouldn’t feel anything because the doctor will administer local anaesthetic to the area before doing the RFA technique. If you have any pain or discomfort thereafter, it will be minimal.
4. The effects might be long-lasting.
The possibility of permanent results is yet another advantage of this therapy. The unhealthy veins are removed, as is the case with the majority of conventional varicose and spider vein treatments. With this procedure, the walls of the veins that are being treated collapse in on themselves. The targeted veins are effectively eliminated when the venous walls give way. Yet it takes a few weeks for the veins to stop receiving blood and disappear.
The most crucial thing to comprehend is that sickness rarely causes healthy veins to become gnarled and twisted.
Consequently, you could only only one treatment session to achieve your ideal outcomes, depending on the number of varicose or spider veins you need to treat, their size, the reason they are disordered, and where they are located.
5. It Is Without Needles
The most common non-invasive varicose and spider vein treatment is sclerotherapy, however it is not appropriate for everyone. Sclerotherapy’s main drawback is that treatment necessitates the injection of a saline solution. Sadly, many people dislike the concept of being injected, even with merely seawater, or are scared of needles.
Am I eligible for RFA?
The best approach to find out if you qualify is to get a consultation and thorough evaluation from a qualified pain specialist.
Your doctor conducts a physical examination in addition to reviewing your medical history and talking about your present symptoms. Also, our team runs any essential testing to rule out any underlying diseases that would make RFA an ineffective treatment option.
RFA is typically an useful alternative for people whose pain has subsided following a brief diagnostic nerve receptor block. RFA is not a smart choice, however, for pregnant women or those who may get pregnant, persons with bleeding issues, or those who are currently ill.
