This study aimed to investigate the outcome of hybrid endovenous laser ablation (EVLA, 1470 nm) and radiofrequency ablation (RFA) procedures for varicose veins (VVs).

Material and methods:
We retrospectively analyzed the clinical data of patients from July 2019 to December 2020. Eighty-four patients (121 limbs) underwent hybrid EVLA procedure, and 108 patients (151 limbs) underwent RFA procedure. The outcomes, venous clinical severity score (VCSS), chronic venous disease quality-of-life questionnaire (CIVIQ-20) score and recurrence at 1, 6, and 12 months were collected.

No differences in complications or 24-h pain scores were noted between the two procedures, but a lower dosage of foam sclerosant was used in EVLA procedure than in RFA procedure (P<0.02). The postoperative VCSS and CIVIQ-20 scores in two groups were significantly decreased compared with the scores before the procedure, and no differences in scores were noted between the two procedures at 1 month. However, the VCSS and CIVIQ-20 scores for EVLA procedure were significantly better than those for RFA procedure at 6 and 12 months (P<0.05). Both procedures showed a similar great saphenous vein closure rate at 12 months. The EVLA procedure showed lower rates of overall recurrence (4.96% vs. 14.57%, OR: 3.27, 95% CI: 1.33-8.00, P=0.01) and recurrence below the knee (4.13% vs. 11.92%, OR: 3.14; 95% CI: 1.18-8.35, P=0.02). Moreover, the patient satisfaction score was greater for EVLA procedure than RFA procedure (P<0.02).

The hybrid EVLA (1470 nm) procedure reduces VV recurrence below the knee and results in better quality-of-life scores.
