Radiofrequency Vein Ablation in Los Angeles
Minimally Invasive Varicose Vein Treatment

Radiofrequency vein ablation is a non-surgical vein treatment that is used to treat varicose veins. Also called VNUS closure, ClosureFast, and other trade names, radiofrequency vein ablation delivers targeted thermal energy to safely close down problem veins and restore healthy circulation in the leg.
Radiofrequency vein ablation has been one of the go-to varicose vein treatments for nearly two decades. It is clinically proven to provide relief from leg discomfort and swelling, and can also provide aesthetic improvements to legs that are visually affected by varicose veins. The procedure typically takes about 30 to 60 minutes depending on the extent of your vein problems, and you’re able to resume your normal activities immediately after the procedure.

Vein problems? We can help you get your legs back with radiofrequency vein ablation in Los Angeles.
Dr. Michael Lalezarian is a double-board certified Vascular Interventional Radiologist specializing in minimally invasive vein treatments. He is a committed partner in the battle against the devastating consequences of venous insufficiency.
“I was referred to Dr. Lalezarian from my orthopedic surgeon for varicose vein treatment options. From the second I walked into the office, I was at ease and felt very welcomed from Kimberly and the staff. Upon meeting the doctor, he was so kind and fully explained my options after the initial ultrasound on both legs. I decided to go with the sclerotherapy and am so happy that I did. The procedures were quick and virtually painless but the results are life changing for me. The pain suffered for so many years and countless sleepless nights are a thing of the past.”

What is Radiofrequency Vein Ablation?
Radiofrequency vein ablation uses thermal energy to effectively close down varicose veins. When applied to the inside of a varicose vein, thermal energy causes the walls of the vein to collapse. The elimination of a major varicose vein then causes blood to resume flow through nearby healthy veins, which helps to restore healthy circulation in the leg. [1]
The radiofrequency vein ablation procedure is performed using a catheter-based device that is outfitted with a heating element and connected to a radiofrequency (RF) generator. Prior to activating the heating element, the saphenous compartment, which surrounds the vein, is filled with a liquid referred to as tumescent anesthesia. Tumescent anesthesia acts as a heat sink to protect surrounding tissue from excessive temperatures during treatment, and also numbs the area to minimize any pain or discomfort during the procedure. [1]
Is Vein Ablation Clinically Proven?
Varicose Vein Radiofrequency Ablation Recovery
Varicose vein radiofrequency ablation recovery time is minimal. There are very few limitations to your normal activities after the procedure, and most patients are encouraged to walk and resume their daily activities immediately afterwards. Following vein treatment, you will likely be prescribed compression stockings to wear day and night on the treated leg(s) for 3 to 5 days following the procedure. Compression stockings help to ensure permanent vein closure.
Most patients report an immediate improvement in their pain symptoms following vein treatment, but visible changes to the leg can take 1 to 3 months to heal and return to normal. We’ll ask you back for follow-up evaluations 4 weeks after your procedure to check on the status of your veins and provide additional treatment if necessary.
Vein Radiofrequency Ablation Side Effects
Varicose Vein Radiofrequency Ablation Complications
Varicose vein radiofrequency ablation complications are uncommon. In rare instances, heat-induced thrombosis (clotting) or other thermal injuries such as nerve damage may occur as a result of radiofrequency vein ablation. [5] There are also a minority of cases in which the treated vein may fail to close completely and re-open some time after the procedure. [2] These occurrences are typically addressed with an additional procedure.
Even though the chances are minimal, the risk of radiofrequency vein ablation complications emphasizes the importance of seeing a board-certified Vascular Specialist about your veins, to ensure you’re receiving the highest quality of care from a trained professional.
