The Laseev laser comes in 2 laser waves- the 980nm and the 1470 nm.
(1)The 980nm laser with equal absorption in water and blood, offers a robust all-purpose surgical tool, and at 30Watts of output, a high power source for endovascular work.
(2)The 1470nm laser with significantly higher absorption in water, provides a superior precision instrument for reduced collateral thermal damage around venous structures.
Accordingly, it is highly recommended for endovascular work to use 2 laser wavelengths 980nm 1470nm blended.
The procedure for EVLT treatment
The EVLT laser procedure is carried out by inserting the laser fibre into the affected varicose vein (endovenous means inside the vein). The detailed procedure is as follows:
1.Apply a local anaesthetic over the affected area and insert a needle in the area.
2.Pass a wire through the needle up the vein.
3.Remove the needle and pass a catheter (thin plastic tubing) over the wire into the saphenous vein
4.Pass a laser radial fibre up the catheter in such a way that its tip reached the point that needs to be heated the most (usually the groin crease).
5.Inject enough local anaesthetic solution into the vein through multiple needle pricks or by Tumescent anesthesia.
6.Fire up the laser and pull the radial fibre down centimetre by centimetre in 20 to 30 minutes.
7.Heat the veins through the catheter causing homogenous destruction of the vein’s walls by shrinking it and sealing it off. As a result, there is no more blood flow in these veins that may result in swelling. The surrounding healthy veins are free of the varicose veins and therefore able to resume with the healthy blood flow.
8.Remove the laser and the catheter and cover the needle puncture wound with a small dressing.
9.This procedure takes 20 to 30 minutes per leg. The smaller veins may need to undergo sclerotherapy in addition to the laser treatment.
