Endovenous Laser Ablation

Endovenous Laser Ablation

Chronic venous insufficiency of the lower extremity is a common vascular disorder ranging between 25–40% and 10–20% in women and men, respectively. This unsightly condition was previously treated by stripping surgery. Recently, Endovenous laser ablation (EVLA) has become one of the most popular and very effective minimally invasive treatment for varicose veins.

 
EVLT Treatment sequence

With local anesthesia, and under ultrasound guidance, an optical fiber is inserted into the Greater Saphenous vein through a tiny incision, usually near the knee. Then the fiber is guided through abnormal vein to the starting point of the procedure. When laser in turned ON, its light is absorbed inside the vein causing it a thermal injury, and sclerosis of vein wall. A slow withdrawing of the optical fiber along affected varicose vein causes its collapse with minimal discomfort. The published success of EVLA treatment is between 95-98%, with far fewer complications than surgery. 

Lasers operating at many different wavelengths have been studied for this procedure. In early studies laser diodes at 810, 940, and 980nm, as well as Nd:YAG at 1064 nm were employed. It was assumed that the hemoglobin in intravascular red blood cells was responsible for the absorption of laser radiation. However, recently the attention shifted towards longer wavelengths 1320nm, 1470nm and 1940nm were the absorption target is water. It is hypothesized that a lower linear endovenous energy density due to the strong water absorption leads to a reduction in adverse events.
