Effect of Compression Stockings after Endovenous Laser Ablation of the Great Saphenous Vein with a 1470 nm Diode Laser Device and a 2ring Fiber.

The aim of this study was to demonstrate the effects of compression following the endovenous laser ablation (EVLA) of incompetent great saphenous veins (GSVs) using a 1470 nm diode laser (Ceralas E 1470 nm, biolitec) and a 2ring radial fiber (ELVeS Radial 2ring™, biolitec). In this single-center prospective study, 150 legs of 150 consecutive patients were randomly allocated to one of three groups (A, B, and C). Group A patients did not undergo postoperative compression. Group B patients wore a thigh-length graduated compression stocking (23-32 mmHg) for 7 days, whereas group C patients wore the same stocking for 28 days. No additional phlebectomies or sclerotherapies were performed. Investigations were performed prior to intervention, at the day of intervention (D0), at day 7 (D7), and at day 28 post intervention (D28). The primary endpoint was post-interventional pain measured on a 10-point scale. A significant but small pain decrease was observed in the first week of compression, by comparing group B's mean pain scores to those of group A ( = 0.009). Wearing a compression stocking after EVLA reduced pain within the first week on a significant, but low level. Taking the very low differences in pain levels into account, the difference may not be clinically relevant and post-treatment compression may not be necessary if no additional phlebectomies or sclerotherapies are performed.
