The study was aimed at comparing clinical and ultrasonographic results during 3 years of postoperative follow up of patients presenting with lower limb varicose veins (LLVV) and subjected to either surgical or thermal-ablation procedures for removal of pathological reflux along the great saphenous vein (GSV) within the femur The study included a total of 185 patients with clinical class C2-3 LLVV in the system of the GSV. The patients were divided into three groups: Group One consisted of 63 patients subjected to short stripping of the GSV trunk + treatment of the perforant veins (66.7%); Group Two comprised 61 patients undergoing endovenous laser coagulation (EVLC) of the GSV trunk + EVLC of the perforant veins (73.7%); Group Three was composed of 61 patients undergoing radiofrequency ablation of the GSV trunk + ELVC of the perforant veins (70.4%). Complaints were dynamically assessed by the VCSS scale with ultrasonographic duplex scanning. It was revealed that pathological reflux along the GSV trunk on the crus at 1, 2 and 3 years of follow up was registered: in Group One in 33.3, 36.3 and 39.1% of cases, respectively; in Group Two in 15, 14.2 and 25% of cases, respectively; and in Group Three - in 11, 18.1 and 23.8% of cases, respectively. Group One patients at 1 year were found to have developed vertical refluxes emerging on the femur along the GSV tributaries (22.1% of cases), the presence of horizontal refluxes along newly-formed perforant veins (44.4% of cases). The diameter of the GSV trunk on the crus statistically significantly increased with years in all groups. The average diameter of the perforant veins increased at the same time periods of follow up. Alterations of venous haemodynamics revealed on ultrasonographic examination were accompanied by varicose syndrome but exerted no significant effect on subjective symptomatology in patients during 3 years of follow up. The obtained findings are indicative of progression of LLVV in part of surgically treated patients, which requires dynamic follow up and carrying out systemic pharmacotherapy.

Background: to compare different anesthesia protocols during High Intensity Focused Ultrasound (HIFU) for saphenous trunk (GSV/SSV) and/or varicosities incompetence treatment.
Material And Methods: patients with GSV/SSV incompetence with varicose veins underwent HIFU under different anesthesia protocols. The primary endpoint was the pain score during HIFU using a 10-point scale.

Article Synopsis
- A descriptive study was conducted using an automated microfoam preparation system (AMPS) for foam sclerotherapy in treating varicose veins, involving 185 patients from February 2021 to December 2022.
- The average treatment involved different volumes and concentrations of foam for various types of veins, with high occlusion rates reported after 15 months, particularly for the great and small saphenous veins.
- The study found a low complication rate overall, indicating that the AMPS could be a versatile and effective option for treating venous diseases while minimizing adverse events.

Objective: To determine the sex prevalence of lower limb varicose networks fed by reflux of the great saphenous vein (GSV), anterior accessory saphenous vein (AASV), and small saphenous vein singularly or in combination.
Methods: We scanned by the means of the same color Doppler ultrasound protocol 3000 lower limbs in 1500 consecutive patients, affected by symptomatic chronic venous insufficiency from 2013 to 2023. Limbs with normal venous function, incomplete scans, or that were affected by post-thrombotic syndrome, pelvic reflux, isolated perforator reflux, venous malformation, phlebolymphedema and Clinical, Etiological, Anatomical, Pathophysiological clinical class C5 and C6 were excluded from the final analysis.

Article Synopsis
- Isolated ambulatory phlebectomy is a treatment option for patients with incompetent great saphenous veins (GSV) and tributaries, and identifying which patients may benefit is crucial.
- The study utilized data from the SAPTAP trial to develop a multivariable model predicting the likelihood of avoiding secondary axial ablation after the procedure, testing various patient characteristics as predictors.
- The final model identified three key predictors: tributary length, presence of saphenofemoral junction reflux, and trunk diameter, showing moderate effectiveness in predicting outcomes to inform patient treatment planning.
