Vein Closure / Enovenous Laser Treatment (EVLT)
Dr. Maffei uses the VenaCure EVLT system from AngioDynamics. Laser vein treatment is a minimally invasive alternative to traditional surgical ligation and stripping of the veins. Because it’s minimally invasive, it can be performed in an out-patient setting, and requires only local anesthesia. Procedure time is less than two hours, with the actual procedure taking about 45 minutes. Patients experience significantly less discomfort, as compared to surgery, both during and after the treatment, and are able to resume to normal activity immediately following the procedure.
The procedure works by using highly concentrated laser light emitted into the target area through a thin fiber that is inserted into the vein. The laser heats the blood in the vein, causing the vein wall to collapse. This results in the vein being closed off and preventing further backflow or reflux from that vein.
Endovenous laser ablation of the saphenous vein utilizes a small laser fiber that is inserted through a small incision in the skin into the vein, all done with ultrasound guidance. Pulses of laser light are emitted inside the vein, heating the vein wall causing it to collapse, scar, and seal shut. A bandage or compression hose is placed on the treated leg following the treatment.
Procedure: The ablation technique involves placing a needle and a catheter into the target vein under sterile conditions. Local anesthesia is used to numb the skin so that placement of the catheter does not hurt. The catheter is positioned near to where the superficial vein empties into the deep veins. The area around the treated vein requires additional injections of a liquid preparation called tumescent anesthesia which both numbs the nerves around the vein, and collapses the vein around the catheter, and protects surrounding tissue. The laser technique “closes” or ablates the vein using heat damage to occlude the vein.
Once the incompetent vein has been ablated, blood flow is diverted to other competent collateral veins, thereby relieving the downward pressure from the refluxing vein.
Endovenous ablation procedures treat the cause of venous insufficiency (reflux) and are effective in treating medical symptoms. Cosmetic improvements are also generally seen, but sometimes adjunctive procedures (such as sclerotherapy or ambulatory phlebectomy) are required to obtain optimal cosmetic results).
