If your legs ache, swell, or feel heavy by the end of the day, leaky vein valves may be the reason. This condition is called venous reflux, and it is one of the most common problems I treat. The good news is that venous reflux treatment has come a long way. Today, most patients can get relief through simple daily habits or a minimally invasive procedure in the office. In this article, I explain what venous reflux is, how I diagnose it, and how I choose the right treatment for each patient.
Key Takeaways
- Venous reflux happens when one-way valves in the leg veins leak, letting blood flow backward and pool.
- Common symptoms include aching, heaviness, swelling, itching, night cramps, skin darkening, and slow-healing sores near the ankle.
- Compression, walking, and leg elevation help many people, but they do not repair the leaking vein.
- Radiofrequency ablation closes the leaking vein from the inside, and sclerotherapy treats smaller branch veins.
- A duplex ultrasound comes first, so treatment targets the exact veins that are causing your symptoms.
What Is Venous Reflux?
Your leg veins carry blood back up to your heart. Because they work against gravity, they rely on small one-way valves. When those valves weaken or stop closing, blood leaks backward and pools in the lower legs. This backward flow is called reflux. Over time, it leads to a condition known as chronic venous insufficiency.
Reflux most often affects the great saphenous vein, which runs up the inside of the leg, or the small saphenous vein in the back of the calf. As pressure builds, nearby branch veins stretch and bulge into varicose veins. Risk factors include family history, age, pregnancy, extra weight, a past blood clot, and long hours standing or sitting.
Symptoms of Venous Reflux
Reflux tends to get worse slowly, so many people get used to the symptoms. Common signs include:
- Aching, tired, or heavy legs, especially late in the day
- Swelling in the ankles and lower legs
- Itching, burning, or throbbing along the veins
- Cramping or restless legs at night
- Brown discoloration, dryness, or thickening of the skin near the ankle
- Open sores that heal slowly, known as venous leg ulcers
According to MedlinePlus, from the National Library of Medicine, venous insufficiency can cause swelling, pain, skin changes, and ulcers when left untreated. For this reason, I encourage patients not to wait until the skin starts to change.
How I Diagnose Venous Reflux
Every evaluation starts with a duplex ultrasound. This painless test lets me watch blood flow in real time. With it, I can see which valves leak, how far the reflux extends, and whether the deep veins are healthy. It also helps rule out a blood clot.
That map matters. In fact, treating the visible veins without fixing the leak underneath is a common reason veins come back.
Venous Reflux Treatment Starts With Daily Habits
For mild symptoms, I usually start with conservative care. These steps help many people feel better:
- Compression stockings. Steady pressure helps push blood upward and reduces swelling. My guide on choosing compression stockings can help you pick the right pair.
- Daily walking. Your calf muscles act like a pump. So regular walking moves blood out of the lower legs.
- Leg elevation. Raising your legs above heart level for 15 to 20 minutes a few times a day eases pressure.
- Healthy weight. Extra weight adds strain to the leg veins.
- Movement breaks. If you sit or stand for long periods, change position and flex your ankles often.
These habits relieve symptoms. However, they do not repair a leaking valve. When symptoms continue or skin changes appear, a procedure is often the better path.
Minimally Invasive Procedures for Venous Reflux
Today, most venous reflux treatment is done in the office. There is no hospital stay and no general anesthesia. The goal is to close the leaking vein so blood reroutes through healthy veins nearby.
Radiofrequency ablation. This is the method I use most to close a leaking saphenous vein. I numb the skin and place a thin catheter into the vein through a tiny puncture, using ultrasound to guide it. Then the catheter gently heats the vein wall, and the vein seals shut. Over time, your body absorbs it. I explain each step in how radiofrequency ablation works.
Sclerotherapy. After the main leak is closed, smaller branch veins and spider veins may remain. In that case, I inject a solution that closes them. This is often the second step in a complete plan.
Other closure methods exist, such as laser ablation and medical adhesive. They work on the same basic idea. Open vein stripping surgery is rarely needed today.
What Recovery Looks Like
Most patients walk out of the office after the procedure. You can usually return to light daily activity within a day or two. I recommend:
- Walking several times a day to keep blood moving
- Wearing compression stockings as directed
- Avoiding heavy lifting, hard workouts, hot tubs, and baths for a short time
- Keeping your follow-up ultrasound, which confirms that the vein has closed
Some tightness, mild soreness, or bruising along the treated vein is common and usually fades over a couple of weeks. Over-the-counter pain relievers and walking usually help.
Which Treatment Is Best for You?
There is no single best treatment for everyone. Instead, the right choice depends on which veins are leaking, how severe your symptoms are, your overall health, and your goals. Some patients do well with compression and walking alone. Others need ablation, sclerotherapy, or both. We will decide together after reviewing your ultrasound.
