“…Since the diameter of the vein is considerably reduced after tumescent anesthesia, it should be systematically measured. A recent study by Desmyttere et al have demonstrated that after tumescent anesthesia, the vein diameter was usually reduced down to 5 mm and usually less [1,24]. For this reason, calculations were performed for a maximum vein diameter of 5 mm.…”

“…These observations were recently confirmed by mathematical modeling of endovenous laser treatment. It was clearly demonstrated that blood plays a minor role during ELT [24,33,34]. Moreover, the treatment is performed by emptying the vein lumen using leg elevation (Trendelenburg positioning), peri-saphenous subcutaneous tumescent saline solution infiltration, and manual compression.…”

“…Since the LEED is a major determinant of treatment outcome, it was calculated to be correlated to the values reported in the literature when using similar parameters (wavelength, vein diameter, power, pullback speed) [23][24][25].…”

Numerical simulations are in agreement with LEED reported in clinical studies. Mathematical modeling shows clearly that 1,320 nm, with a better absorption by the vessel wall, requires less energy to achieve wall damage. In the 810-1,320-nm range, blood plays only a minor role. Consequently, the classification of these lasers into hemoglobin-specific laser wavelengths (810, 940, 980 nm) and water-specific laser wavelengths (1,320 nm) is inappropriate. In terms of closure rate, 980 nm and 1,320 nm can lead to similar results and, as reported by the literature, to similar side effects. This model should serve as a useful tool to simulate and better understand the mechanism of action of the ELT.

“…To reduce the amount of blood inside the vein, the patients were maintained in Trendelenburg position in which the patient is on an elevated and inclined plane at 20°with the head down and legs and feet over the edge of the table. 16 Procedure. Duplex ultrasonography (Aloka 3500, Decines, France) was performed in the upright position to map incompetent sources of venous reflux and then to mark the skin overlying the incompetent portion of the GSV starting at the SFJ.…”

“…However, all these studies are based on the assumption that during EVLA, the vein is filled with blood. Based on our clinical experience on more than 1,000 patients, the presence of blood inside the vein has several consequences [5,6]: -Blood around the fiber tip reduces the transmission of light to the biological target of EVLA, the venous wall [7]. Since thermal damage of the inner vein wall (tunica intima) is required to achieve the tissue alterations necessary for permanent vein occlusion, the presence of blood greatly hinders the effect of the laser to the vessel wall.…”
