| Popis: | Objective The ambulatory selective variceal ablation under local anesthesia (ASVAL) technique subscribes to the “ascending” theory of varicose vein etiology, which recommends primary ambulatory phlebectomy as a treatment for tributary varicosities and truncal vein incompetence. This systematic review explores the efficacy and safety of the ASVAL technique for the treatment of symptomatic varicose veins. Methods A comprehensive search of the Medline and Embase databases and the Cochrane Register of Controlled Trials in May 2019 revealed 11 original articles that were qualitatively reviewed. The primary outcome was the absence from recurrent varicose veins at 1-year follow-up. Secondary outcomes were resolution of great saphenous vein (GSV) reflux on duplex ultrasound, change in GSV diameter, objective and subjective clinical improvement in chronic venous disease, and patient-reported outcome measures. Results A total of 2106 limbs underwent intervention in 1734 patients reported in two randomized controlled trials, one case control study, three cohort studies, and five case series. Varicosity recurrence at 1 year ranged from 0.5% to 13.5% in patients. Of 1622 limbs with diagnosed GSV incompetence before intervention, 1114 were competent at 1 year (mean, 68.2% [±12.62%]). All studies measuring GSV diameter reported statistically significant reductions in vein size. Conclusions ASVAL may be considered as a minimally invasive treatment for early stages of chronic venous disease in the presence of truncal reflux. The evidence base should be strengthened by prospective randomized controlled trials that follow standardized procedures and report according to recognized measures of quality of life alongside clinical and hemodynamic data. |
