RESUMEN
OBJECTIVE: To compare the outcomes of ultrasound guided foam sclerotherapy (UGFS) and endovenous laser ablation (EVLA) to treat isolated small saphenous vein (SSV) incompetence in a multicentre randomised controlled study (RCT; ClinicalTrials.gov identifier: NCT05468450). METHODS: Patients aged ≥ 18 years undergoing isolated SSV treatment (reflux > 0.5 seconds) were randomised to UGFS or EVLA. Patients treated with UGFS were allowed one additional truncal treatment at six weeks. Tributary treatments (phlebectomy or sclerotherapy) were permitted after six months. Participants were assessed at eight days, six months, and one, two, and three years. The primary endpoint was the absence of SSV reflux (> 0.5 seconds). Secondary outcomes included clinical scores and quality of life (QoL) scores. All analyses were done by intention to treat. RESULTS: Of 1 522 screened patients, 161 were randomised to UGFS (n = 82) and EVLA (n = 79). Only 3% of patients who received UGFS had the second (allowed) treatment and 86% of patients completed the three year study. Forty-one and 19 tributary treatments (by sclerotherapy) were performed in 27 UGFS patients (33%) and 15 EVLA patients (19%), respectively. The complete absence of reflux at three years was significantly better after EVLA (86%) than after UGFS (56%) (odds ratio [OR] 5.36, 95% confidence interval [CI] 2.31 - 12.44; risk ratio 1.59, 95% CI 1.26 - 2.01). Two deep vein thromboses (DVTs; one femoropopliteal and one gastrocnemius) and one endovenous heat induced thrombosis occurred in the EVLA group. Seven DVTs were seen in the UGFS group, including two partial popliteal DVTs and five gastrocnemius vein thromboses (four asymptomatic and incidental on day 8 screening). At three years, there was no difference between groups for the following: rate of visible varices (p = .87), revised Venous Clinical Severity Score (p = .28), and QoL (p = .59). Patient satisfaction scores were high in both groups (median score: EVLA 97/100 and UGFS 93/100; p = .080). Symptoms were significantly improved in both groups. (p < .001) CONCLUSION: Technical success was better for EVLA than for UGFS three years after SSV treatment. This agrees with studies that have reported on these treatments in the great saphenous vein. However, improvements in clinical outcome were similar for both groups.

OBJECTIVE: The aim was to evaluate the distribution of the diameter of the great saphenous vein (GSV) at mid-thigh level and to investigate its association with clinical class, symptoms, and proximal extent of reflux. METHODS: Vascular physicians, members of the French Society of Phlebology, were invited to participate in a consecutive observational study in patients presenting with symptoms and/or signs of uni- or bilateral chronic venous disorders (CVDs) in previously untreated limbs (clinical class of the CEAP classification C0s - C6). Patients were included between January and March 2015. They completed a specially designed venous symptoms questionnaire. Duplex ultrasound of the included limbs was performed with the patient standing to detect reflux in the GSV and to measure the GSV inner diameter at mid-thigh. RESULTS: Between January and March 2015, 35 physicians examined 1245 patients (2450 limbs after excluding 40 limbs): 77% were female, mean age 52 ± 14; 69% of the patients had venous symptoms in one or both legs. The most frequent symptoms were feeling of heaviness, feeling of swelling and aching. Predominant CEAP clinical classes were C2 (38% of limbs) and C1 (35%). In case of GSV reflux (40% of limbs), the average diameter was 5.6 ± 2 mm and the distribution was 62% < 6 mm, 30% between 6 and 8 mm, and 8% > 8 mm. The study showed a clear association between clinical class and GSV diameter (the higher the clinical class, the larger the diameter; p < .0001), between venous symptoms and diameter (the larger the diameter, the higher the intensity of symptoms, p < .0001 for overall discomfort) and between proximal extent of reflux and diameter (the more proximal the extent of reflux, the larger the diameter, p < .0001). CONCLUSION: The DIAGRAVES study demonstrated that in France for patients consulting with CVDs, more than half of the incompetent GSVs had a diameter < 6 mm, while large diameters were relatively infrequent. This should be kept in mind when considering management strategies in patients with CVDs.

Published scientific evidence demonstrate the current spread of healthcare misinformation in the most popular social networks and unofficial communication channels. Up to 40% of the medical websites were identified reporting inappropriate information, moreover being shared more than 450,000 times in a 5-year-time frame. The phenomenon is particularly spread in infective diseases medicine, oncology and cardiovascular medicine. The present document is the result of a scientific and educational endeavor by a worldwide group of top experts who selected and analyzed the major issues and related evidence-based facts on vein and lymphatic management. A section of this work is entirely dedicated to the patients and therefore written in layman terms, with the aim of improving public vein-lymphatic awareness. The part dedicated to the medical professionals includes a revision of the current literature, summing up the statements that are fully evidence-based in venous and lymphatic disease management, and suggesting future lines of research to fulfill the still unmet needs. The document has been written following an intense digital interaction among dedicated working groups, leading to an institutional project presentation during the Universal Expo in Dubai, in the occasion of the v-WINter 2022 meeting.
