Objective: Conservatrice et Hémodynamique de l'Insuffisance Veineuse en Ambulatoire, the French acronym for CHIVA, is a strategy aimed to convert a venous reflux into a physiological drainage. We compared CHIVA with radiofrequency ablation and determined its possible advantages.

Methods: We retrospectively analyzed the clinical recurrence, ultrasound recurrence, quality of life scores, and complications. They were compared after propensity score matching.

Results: 212 limbs of 166 patients were included: 42 limbs underwent radiofrequency ablation and 170 limbs underwent CHIVA. The hospital stay was shorter in the CHIVA group. There was no difference in clinical, ultrasound recurrence, quality of life scores and complications between the two groups. The preoperative saphenous vein diameter was larger in the recurrence cases.

Conclusions: CHIVA showed comparable results to radiofrequency ablation. There was more ultrasound recurrence with larger vein diameters. The CHIVA appears to be a simple and more efficient treatment method when performed on select patients.

Objectives: The objective of this study was to evaluate the clinical efficacy of a two-step endovenous laser ablation (EVLA) protocol for treating long-reflux great saphenous veins (GSV) below the knee (BK) while preventing saphenous nerve injury.

Methods: A total of 370 legs with long-reflux to BK-GSV underwent EVLA using a Biolitec 1470 nm laser system and a radial 2-ring slim fiber. The above-knee GSV was ablated at 7 W (50-70 J/cm), and the BK-segment was ablated at 5 W (20-25 J/cm) in a two-step.

Results: The average ablation length was 51 cm, including 28 legs treated over 60 cm. Saphenous nerve injury was not observed in any patients. One month later, ultrasonography revealed complete occlusion of all treated GSV.

Conclusions: Our EVLA protocol for treating BK-GSV was found to be a safe and efficient procedure.

Objective: Ablation with n-butyl cyanoacrylate is a clinically newer technique than endovenous laser ablation and other interventional techniques in the treatment of chronic venous insufficiency (CVI). The aim of this study was to compare the endovenous laser ablation (EVLA) and n-butyl cyanoacrylate (NBCA) interventional techniques in terms of benefit, effectiveness, and patient satisfaction.

Materials and methods: The study was conducted at Yozgat City Hospital and Bozok University Research Hospital Cardiovascular Surgery clinics between November 2016 and February 2021. A total of 260 symptomatic patients with 130 randomized cases in each intervention group were included. NBCA patients constituted Group 1 and EVLA patients Group 2. The saphenous vein was evaluated by color Doppler ultrasonography (CDUS) of the lower extremity. Patients with saphenous veins over 5.5 mm in diameter and a saphenous-femoral reflux time of 2 s or longer were included in the study. The patients were asked about their satisfaction and symptoms in the first postoperative week during an outpatient clinic follow-up with CDUS investigation at the first and sixth months.

Results: Although vena saphenous magna (VSM) closure results were similar with the two methods, satisfaction rates were found to be higher with the NBCA procedure.

Conclusion: Comparison of the new methods used in the treatment of CVI revealed similar VSM closure rates in the two methods, but the satisfaction rate was higher with the NBCA technique in this study.

Objective: The aim of this study was to establish the efficacy of three different strengths of compression systems in the prevention of venous leg ulcer (VLU) recurrences during a 10-year follow up period.

Methods: An open, prospective, randomized, single-center study included 477 patients (240 men, 237 women; mean age 59 years). Patients were randomized into three groups: Group A) 149 patients (allocated to wear elastic stocking 18-25 mmHg). Group B) 167 patients (wearing compression device exerting 25-35 mmHg), and Group C) 161 patients (treated with multilayer compression system exerting 35-50 mmHg).

Results: Overall, 65% (234/360) of patients had recurrent VLU within 10 years. Recurrence occurred in 120 (96%) of 125 in group A, in 89 (66.9%) of 133 patients in group B and in 25 (24.5%) of 102 patients in group C (p < 0.05).

Conclusion: Compression systems with the higher compression class provide lower recurrence rate.

Objectives: To assess the treatment effectiveness of inferior vena cava filters (IVCF) versus non-IVCF for patients undergoing varies conditions.

Methods: We systematically searched the databases to identify eligible RCTs from their inception up to 9/20/2020. The primary endpoint was pulmonary embolism (PE), while the secondary endpoints included deep-vein thrombosis (DVT), major bleeding, and all-cause mortality. The RRs with 95% CIs were applied as effect estimates for the treatment effectiveness of IVCF versus non-IVCF and calculated by using the random-effects model.

Results: 1,137 patients of 5 RCTs were enrolled. There were no significant differences between IVCF and non-IVCF for the risk of PE, major bleeding, and all-cause mortality, while the risk of DVT was significantly increased for patients treated with IVCF.

Conclusions: The use of IVCF did not yield any benefits on PE, major bleeding, and all-cause mortality risk for patients undergoing various conditions, while the risk of DVT was significantly increased for patients treated with IVCF.

Background: Methylene blue (MB) is a conventional lymphatic tracer. We evaluated the application of indocyanine green (ICG) lymphography combined with MB staining in lower limb lymphaticovenular anastomosis (LVA).

Methods: A total of 49 patients with lower limb lymphedema were selected as the study subjects and divided into the research (n = 27) and control groups (n = 22). The patients were treated with LVA using ICG lymphography combined with MB staining and simple ICG lymphography as the positioning method, respectively. The number of lymphatic vessels anastomosed and the operating time were compared between the groups. Lower Extremity Lymphedema Index (LEL index) and Lymphoedema Functioning, Disability and Health Questionnaire for Lower Limb Lymphoedema (Lymph-ICF-LL) were used as prognostic indices; 6 months after LVA, both groups were evaluated for the symptomatic relief of lymphedema.

Results: The number of anastomotic lymphatic vessels in the study group was higher than that in the control group (p < .05), and their procedural time was shorter than that in the control group. The two groups had no significant difference in lymphatic anastomosis time (p > .05). The LEL index and Lymph-ICF-LL of the research and control groups at 6-month follow-up after LVA were lower than those before the operation (p < .05).

Conclusion: The circumference of the affected limb is reduced after LVA in patients with lower extremity lymphedema with a favorable prognosis. ICG lymphography combined with MB staining has the advantages of real-time visualization and accurate localization.
