Unlike other forms of treatment such as stripping, foam sclerotherapy or HF-closure, endovenous laser occlusion is far less complicated for patients. For hospitals, this technique means shorter lengths of stay and thus higher patient turnover. The reason for its positive outcomes lies in the form of treatment itself, with laser surgery being a very safe procedure that allows for great precision.
After puncturing and marking the course of the vein, the physician inserts the guide wire into the vein to be treated under ultrasound control. Once he has slid a catheter of suitable length over it, he pulls the guide wire back out, inserts the laser fiber and removes the spacer this positions the fiber tip exactly at the far end of the catheter so that both can be pulled out together step by step.
A pilot light makes the site of action visible from the outside: The physician activates the laser via the foot switch. A wavelengths of 980 nm and 1550 nm ensure high degree of absorption in both the blood and the vascular wall. This causes the vascular wall to rapidly contract, permanently sealing the vessel. The procedure only takes about 35 to 40 minutes.
In contrast to other techniques, laser treatment is a bloodless procedure the vessel is merely punctured. In vein stripping, on the other hand, a vein is pulled out from the body, often causing large bruises.
