An Original Approach for the Treatment of Varicose Veins of the Lower Limbs

摘要

BACKGROUND: The Triplex method is a three-step treatment approach to reducing the appearance of small and medium-sized varicose veins and phlebological imperfections of the lower limbs. OBJECTIVE: This study evaluated the effectiveness, duration of results, adverse events, patient satisfaction, and improvements in quality of life in patients with small and medium-sized varicose veins who were treated with the Triplex method. METHODS: We conducted a six-year follow-up study of 4,000 patients from the years 2012 to 2018. Patients with chronic venous insufficiency of the lower limbs were included. Patients with active or previous phlebitis or phlebostatic ulcers were excluded. An average of three sessions was performed on each patient in the Triplex group. Follow-up assessments were performed 1, 3, 6, and 12 months after the completion of the treatment, and they included a morphofunctional study, histological examination, and photographic documentation. The first step of the treatment approach utilized an injectable shrinkage solution consisting of sodium salicylate, physiological solution with 10% glycerol, and lidocaine, which was injected into the varices to trigger a reduction of the vessel lumen. For patients in whom the targeted vessels were not sufficienty narrowed by the shrinkage solution, the second step — ultrasound-guided foam sclerotherapy, or scleromousse — was utilized, which consisted of either lauromacrogol 1% or sodium tetradecyl sulfate 1%, with one group of patients (n=50) receiving the former and the other group of patients (n=50) receiving the latter. All patients were administered Step 3 of the treatment approach, which usually included varicose treatment with low concentrations of sodium tetradecyl sulfate (STS) 0.2 to 0.50% or lauromacrogol 0.25%, with compression additionally prescribed in some patients. RESULTS: Over a follow-up period of six years, in patients who underwent full Triplex treatment, we observed 1) a greater duration of the narrowing of the vessel’s caliber, with disappearance of the varices; 2) reduced utilization of the foam solution at the reflux point due to the narrowing of the gauge; and 3) no relevant hemodynamic effects emerged in patients with recanalization. In patients who underwent Steps 1 and 2 of the treatment approach, reflux was not hemodynamically significant. No significant differences were observed in the lauromacrogol group of patients compared to the sodium tetradecyl sulfate group. CONCLUSION: Compared to patients in whom only scleromousse was performed at the reflux site, the narrowing of the varicose wall that is achieved using the Triplex method is associated with longer lasting results in the treatment of small and medium-sized varicose veins, with physiological recovery of superficial venous circulation.
