What this Trial Is About
Technically successful laser crossectomy will reduce the risk of reflux recurrence at the sapheno-femoral junction without increasing the risk of endovenous heat-induced thrombosis, which may positively impact the likelihood of ultrasound- or clinical-recurrence of varicose veins. Similar technical efficacy is expected for laser crossectomy at 1940 nm and 1470 nm. A possible advantage of the 1940 nm wavelength in terms of postoperative pain intensity and the risk of adverse events cannot be ruled out.
