Varicose vein ablation is a minimally invasive treatment for symptomatic varicose veins and underlying venous reflux, a condition in which blood flows backward and pools in the veins of the legs. By closing a malfunctioning superficial vein, ablation redirects blood through healthier veins and can help relieve symptoms associated with venous insufficiency.
Tampa General Hospital (TGH) offers varicose vein ablation and a comprehensive range of vascular surgery services to patients throughout Brooksville, Spring Hill, Crystal River and surrounding communities. Varicose vein ablation procedures are performed at TGH Brooksville, with vascular care available to patients across the region.
What Are Varicose Veins?
Varicose veins are enlarged, twisted veins that develop just beneath the skin, most commonly in the legs. They may appear blue or purple and can bulge or have a cordlike appearance. While varicose veins are sometimes primarily a cosmetic concern, they can also be associated with symptoms or an underlying problem with how blood flows through the veins.
Veins in the legs must carry blood upward against gravity to return it to the heart. Small, one-way valves inside the veins help with this process by opening to allow blood to move toward the heart and closing to help prevent it from flowing backward. When these valves do not function properly, venous reflux can develop.
How Does Venous Reflux Cause Varicose Veins?
Venous reflux occurs when valves inside a vein do not close effectively, allowing some blood to flow backward instead of continuing toward the heart. This backward flow can cause blood to collect in the leg veins and increase pressure within them.
Over time, the affected superficial veins can stretch and enlarge, contributing to the development of varicose veins. Venous reflux can also cause symptoms, such as aching, heaviness, throbbing, swelling, itching or a feeling of tiredness in the legs. More advanced chronic venous disease can lead to skin changes or venous ulcers.
When venous reflux is suspected, a vascular evaluation may include duplex ultrasound to assess blood flow and determine which veins are functioning abnormally. Identifying the source of reflux can help guide treatment rather than addressing only the visible varicose veins.
When Do Varicose Veins Need Medical Treatment?
Varicose veins do not always require medical treatment. If they do not cause symptoms or other health problems, treatment may be pursued primarily for cosmetic reasons.
Medical treatment may be considered when varicose veins or underlying venous disease cause problems such as:
- Persistent aching, throbbing, burning or heaviness in the legs
- Leg swelling
- Itching or irritation around affected veins
- Skin discoloration, thickening or other changes related to chronic venous disease
- Inflammation or bleeding from a varicose vein
- A venous ulcer or wound associated with poor venous circulation
A vascular evaluation can help determine whether symptoms are related to venous reflux and whether treatment is appropriate. When clinically significant reflux is present, the vascular specialist can determine whether treatment of the malfunctioning vein may help relieve symptoms or address complications of venous disease.
What Is Varicose Vein Ablation?
Varicose vein ablation, also known as endovenous ablation, is a minimally invasive treatment that closes a superficial vein affected by venous reflux. Rather than removing the vein through traditional surgery, the procedure treats it from within using a catheter or other specialized device.
Closing the vein might seem counterintuitive, but a refluxing superficial vein is not moving blood efficiently toward the heart. Once the problem vein is closed, blood is naturally redirected through other veins that can more effectively return it to the heart. Over time, the treated vein typically shrinks and is gradually absorbed by the body.
Endovenous ablation can address an underlying source of venous reflux, helping relieve symptoms such as aching, heaviness and swelling. Treating the reflux also may improve associated varicose veins, although some visible veins may require additional treatment.
How Is Vein Ablation Performed?
The precise technique varies according to the type of vein ablation being performed. For thermal procedures, such as laser or radiofrequency vein ablation, the physician will use ultrasound guidance to insert a thin catheter into the affected vein through a small puncture in the skin. Local anesthetic will be administered around the vein, and energy will be delivered through the catheter to heat and close the vein. After the targeted vein is closed, blood is redirected through other functioning veins in the leg.
Is Varicose Vein Ablation Painful?
Varicose vein ablation is generally performed with local anesthesia to minimize discomfort. During thermal ablation, additional anesthetic solution is commonly placed around the vein to help numb the treatment area and protect the surrounding tissues from heat.
The patient may feel pressure, pulling or other sensations during the procedure. Afterward, temporary soreness, tenderness, bruising or a feeling of tightness along the treated vein can occur. The amount of discomfort and how long it lasts can vary according to the treatment performed and the individual patient.
Laser vs. Radiofrequency Vein Ablation
Endovenous laser ablation and radiofrequency ablation are two minimally invasive techniques used to close refluxing superficial veins. Both use thermal energy delivered through a catheter, but the source of that energy differs:
- Laser vein ablation – Laser energy heats the inside of the targeted vein, causing it to close.
- Radiofrequency vein ablation – Radiofrequency energy generates controlled heat that causes the vein wall to collapse and seal.
Both techniques can effectively treat symptomatic superficial venous reflux, but neither approach is universally best for every patient. The treatment selected will depend on the vein being treated, its anatomy and other clinical considerations.
Other nonthermal techniques can also be used to treat certain refluxing veins. A vascular specialist can determine which approach is appropriate for the patient’s venous disease and treatment needs.
When Is Varicose Vein Ablation Recommended?
Varicose vein ablation may be recommended when a patient has symptomatic venous disease and an evaluation confirms that reflux in a superficial vein is contributing to the problem. Duplex ultrasound can help the vascular specialist identify abnormal backward blood flow, determine which veins are affected and assess whether endovenous ablation is an appropriate treatment.
Conservative measures such as exercise, leg elevation and compression stockings may help relieve symptoms for some patients. However, these approaches do not correct the underlying venous reflux. When treatment of the refluxing vein is appropriate, endovenous ablation can close the malfunctioning vein so blood is redirected through healthier veins.
Not every patient with varicose veins or venous reflux needs ablation. The treatment approach depends on the nature and severity of the venous disease, ultrasound findings, the patient’s overall health and treatment goals. Other vein treatments may be recommended instead of or in addition to ablation.
What Is the Difference Between Cosmetic and Medical Vein Treatment?
The distinction generally depends on why treatment is being performed. Cosmetic vein treatment is primarily intended to improve the appearance of visible veins that are not causing significant symptoms or other medical problems. Spider veins, for example, are often treated for cosmetic reasons.
Medical vein treatment addresses symptoms or complications associated with underlying venous disease. When faulty valves allow blood to reflux through a superficial vein, the resulting increased venous pressure can contribute to painful varicose veins, swelling, skin changes and, in more advanced cases, venous ulcers. Ablation can treat the source of this abnormal blood flow by closing the refluxing vein.
The two goals can overlap. Treating medically significant venous reflux may also improve the appearance of varicose veins, but cosmetic improvement is not the primary purpose of medically indicated vein ablation. Some visible varicose veins also may remain after the underlying refluxing vein has been treated and require additional therapy if they continue to cause symptoms or are otherwise bothersome.
What Is Recovery Like After Varicose Vein Ablation?
Because varicose vein ablation requires only a small access site rather than a large surgical incision, recovery is generally brief. Patients are typically encouraged to walk soon after treatment and can often return to many routine activities relatively quickly.
Temporary bruising, soreness or a feeling of tightness along the treated vein may occur as the area heals. The healthcare team will provide instructions about walking, exercise, work and any temporary activity restrictions.
Follow-up care will allow the vascular team to assess healing and symptom improvement. Ultrasound may be performed when appropriate to evaluate the treated vein or investigate symptoms that could indicate a complication.
Are Compression Stockings Needed After Vein Ablation?
Compression stockings may be recommended after vein ablation to provide support and reduce discomfort during the initial recovery period. Whether they are needed and how long they should be worn can vary depending on the type of treatment performed and the patient’s individual needs.
The vascular team will provide specific instructions about compression after the procedure. Patients are also generally encouraged to walk regularly while following any activity restrictions provided by the healthcare team.
What Are the Risks of Varicose Vein Ablation?
Although varicose vein ablation is a minimally invasive procedure, complications can occur. The risks can vary depending on whether laser, radiofrequency or another technique is used.
Possible risks of vein ablation include:
- Bruising, swelling or discomfort – Temporary bruising, swelling, tenderness or tightness can develop along the treated vein.
- Inflammation – The treated vein or nearby superficial veins can become inflamed, causing localized tenderness, redness or firmness.
- Skin changes – Temporary or, less commonly, persistent skin discoloration can occur along the treated vein. Thermal ablation also carries a small risk of a skin burn.
- Nerve irritation or injury – Nearby nerves can occasionally be affected, potentially causing temporary numbness, tingling or other sensory changes.
- Blood clots – A clot can occasionally develop in a superficial or deep vein after treatment. In some cases, clotting associated with the treated vein can extend toward the deep venous system.
- Incomplete vein closure or recurrent reflux – The treated vein may not close completely or may reopen over time, potentially allowing abnormal blood flow to persist or return.
The vascular team will review the potential risks associated with the specific ablation technique and explain which symptoms should prompt medical attention after treatment.
Can Varicose Veins Come Back After Ablation?
Yes. Varicose veins can develop again after vein ablation, but recurrence does not necessarily mean that the original treatment was unsuccessful. Ablation targets specific veins that are allowing abnormal backward blood flow. Over time, other veins can develop faulty valves and reflux, or new varicose veins can form.
In some cases, the previously treated vein can also reopen, a process known as recanalization, or reflux can persist or recur in another part of the superficial venous system. If symptoms or troublesome varicose veins return, a vascular evaluation and duplex ultrasound can help identify the source and determine whether additional treatment is appropriate.
Maintaining a healthy body weight, staying physically active and following other recommendations from the healthcare team can support overall vein health, but there is no guaranteed way to prevent new venous reflux or varicose veins from developing.
When Might Additional Vein Treatment Be Needed?
Closing the primary refluxing vein does not always eliminate every visible varicose vein. Some smaller varicose veins may improve after the underlying reflux is treated, while others can remain symptomatic or prominent.
When needed, additional treatment may be used to address residual or recurrent varicose veins. Options can include procedures such as sclerotherapy or phlebectomy, depending on the veins involved and the source of the problem. In some cases, treatment can be performed at the same time as ablation, while in others the vascular specialist may recommend waiting to see how the remaining veins respond after the primary reflux has been treated.
Follow-up evaluation can help determine whether additional treatment may help relieve persistent symptoms or address other effects of venous disease rather than treating residual veins solely because they remain visible.
