ClosureFast™ (Endovenous Radiofrequency Ablation)
Sessions: 1
Procedure: 30-60 minutes
Recovery: 2/3 weeks
Results: 6-18 Months
Insurance: Typically Covered
Pain : Mild – Moderate
ClosureFast, a system developed by Medtronic, is a method of endovenous radiofrequency ablation (RFA) designed specifically for treating chronic venous insufficiency, which often presents as varicose veins. This minimally invasive procedure uses radiofrequency energy to heat and close off the affected veins.
How many sessions are typically required?
Usually, one session per affected vein is required, but patients with multiple problematic veins may need multiple appointments.
How long is the procedure?
The procedure typically takes about 45 minutes to an hour per vein.
How long is the recovery time?
Most patients can resume normal activities within 1 day. However, they’re often advised to avoid strenuous activities for 1-2 weeks.
How long until results are visible?
Symptomatic relief is often noticed within 1-2 weeks. The cosmetic appearance (reduction of visible varicose veins) improves over the course of several weeks to months.
Does insurance cover the procedure?
Often, yes. If the procedure is performed due to medical necessity (symptomatic varicose veins or venous insufficiency), many insurance companies will cover it. As always, patients should check with their individual insurance provider.
How painful is it?
Mild to Moderate. The procedure is typically done under local anesthesia, and while some patients may feel a warm sensation or slight discomfort, the pain is generally well managed. Some discomfort or bruising may be experienced after the procedure, but this is usually temporary.
What are the risks of ClosureFast™?
Potential risks include burns or skin damage, deep vein thrombosis, pulmonary embolism, nerve damage, infection, and phlebitis (vein inflammation).
The Treatment Process
1.
Catheter is placed in the vein
Using an ultrasound, your doctor will position a catheter into the diseased vein through a small access site.
2.
Specialized adhesive is placed
A specially formulated medical adhesive is placed in the diseased vein via a small
catheter.
3.
Light external pressure is applied
Light external pressure is applied to adhere the vein walls together. This step is repeated for the length of the vein.
4.
Catheter is removed
The catheter is removed and a single adhesive bandage is applied to the
vein access site.
What to Expect
Before the procedure
You will have an ultrasound imaging exam of the leg being treated. This exam is important for assessing the diseased superficial vein and planning the procedure.
During the procedure
You may feel some minor pain or stinging with a needle stick to numb the site where the doctor will access your vein.
Once the area is numb, your doctor will insert the catheter (i.e., a small hollow tube) into your leg. You may feel some pressure from the placement of the catheter.
The catheter will be placed in specific areas along the diseased vein to deliver small amounts of the medical adhesive. You may feel a mild sensation of pulling. An ultrasound will be used during the procedure to guide and position the catheter.
After the procedure
After treatment, the catheter is removed and a small adhesive bandage is placed over the puncture site.
You will be taken to the recovery area to rest.
Your doctor will recommend follow-up care as needed.
