Endovascular Laser Venous Closure Endovascular Laser Venous Closure (Venacure) is a quick minimally invasive procedure. Venacure helps provide relief from painful and unsightly legs to people suffering from varicose veins. What is Endovascular Laser Venous Closure? It is a new procedure that takes about 45 minutes to an hour and is performed in an outpatient setting. Instead of the surgical stripping of varicose veins, patients now have the option of this new minimally invasive laser procedure called Endovascular Laser Venous Closure or Venacue. During the procedure, the area of the leg affected is locally anesthetized and a thin Laser fiber is inserted into the abnormal vein. Delivering the laser energy in short pulses. This laser energy closes off the vein to any future blood flow. The fiber optic probe is then withdrawn from the body and a compression stocking is to be worn for 7 days. Blood no longer gathers and the varicose vein shrinks back to normal size. What to Expect? You should experience minimal discomfort during the procedure. There is very little pain during or after the treatment and you can see a big difference in just two weeks. You may walk immediately after the procedure but vigorous activity should be temporarily avoided. You may have some bruising and soreness for 7-10 days after the treatment. Over-the-counter non-aspirin oral pain relieving medication may be taken as needed. Venacure will normally treat the cause of most varicose veins but additional complimentary therapy may be necessary in some cases.
