Reliability, validity, and minimal clinically important differences for the Thai-version of the Aberdeen Varicose Vein Questionnaire (AVVQ-Thai) in patients with chronic venous disease

Background Patient-reported outcome measures (PROMs) are essential for assessing the health of patients with chronic venous disease (CVD). Therefore, we aimed to translate the Aberdeen Varicose Vein Questionnaire into Thai language (AVVQ-Thai) and evaluate its reliability and validity. Minimal clinically important differences (MCID) of the AVVQ-Thai also be estimated. Methods International standards for PROM translation were followed including the forward-backwards translation of the AVVQ. Patients with Clinical-Etiology-Anatomy-Pathophysiology (CEAP) C2-C6 with truncal reflux were prospectively included. Venous interventions were used to treat reflux and varicosities. Patients’ characteristics, venous clinical severity scores (VCSS), EuroQol EQ-5D, and AVVQ-Thai were collected pre- and one-month post-intervention. AVVQ-Thai was also collected one to two weeks after the initial visit by reply-paid postal questionnaire. Results The study included 119 patients (30% C2, 29% C3, 28% C4, 11% C5, and 2% C6). The AVVQ-Thai had good internal consistency with Cronbach’s alpha of 0.783 and moderate reliability with the intraclass correlation coefficient of 0.67 (95%CI: 0.50, 0.79). The AVVQ-Thai was significantly correlated with VCSS and was able to discriminate patients with different levels of health problems as assessed by EQ-5D at both pre-and post-intervention, demonstrating good construct and discriminative validity. The median AVVQ scores improved significantly after intervention from 15.4 (IQR 8.3, 24.2) to 4.2 (IQR 1.3, 8.4) in C2-C3, and 18.9 (IQR 14.1, 25.5) to 7.3 (IQR 4.6, 16.3) in C4-C6. The MCID of the AVVQ was 6.21 on the 0-100 scale, which equates to the level of difference necessary to be clinically meaningful. Conclusions AVVQ-Thai has satisfactory evidence for internal consistency, reliability, validity, and responsiveness to change and is recommended for application in Thailand.

Clinical efficacy of sodium aescinate administration following endovenous laser ablation for varicose veins.

Endovenous interventions and minimally invasive procedures are effective in the management of varicose veins. However, they can cause postoperative discomfort. To evaluate the clinical efficacy of sodium aescinate (SA) in improving edema, pain, vein-specific symptoms, and quality of life in patients following endovenous laser ablation (EVLA) for varicose veins. In this single-center randomized controlled trial (RCT), patients were allocated into two groups: in Group A, 60mg SA was administered twice daily for 20days, and in Group B (control), no venoactive drug was prescribed. The Clinical-Etiology-Anatomy-Pathophysiology (CEAP) classification system for chronic venous disorders was used to assess the varicose veins. The circumferences of the calf and ankle were recorded for evaluating edema. The 10-point Visual Analog Scale (VAS), Venous Clinical Severity Score (VCSS), and Aberdeen Varicose Veins Questionnaire (AVVQ) were used to measure the pain intensity, overall varicose vein severity, and patient's quality of life, respectively. The study included 87 patients (mean age, 59.9 ± 10.7years; 54 men) with CEAP class C2-C5 varicose veins who underwent EVLA and phlebectomy or foam sclerotherapy. The calf circumference recovered quicker in Group A than in Group B by days 10, 21, and 30 (difference from baseline was 1.04 ± 0.35 vs 2.39 ± 1.15 [p < .001], 0.48 ± 0.42 vs1.73 ± 1.00 [p < .001], and 0.18 ± 0.64 vs 0.82 ± 0.96 [p < .001], respectively). The ankle circumference recovered quicker in Group A than in Group B by days 10 and 21 (the difference from baseline was 1.37 ± 0.52 vs 2.36 ± 0.93 [p < .001] and 0.58 ± 0.60 vs 1.14 ± 0.88 [p = .002], respectively). Pain relief was achieved quicker in Group A than in Group B (0.257 ± 1.097 [p = .0863] vs 0.506 ± 1.250 [p = .0168] by day 21). There were no significant differences in the VCSS and AVVQ scores between both groups. There were no drug-related adverse effects. SA, in combination with compression therapy, can relieve edema and alleviate pain in patients following EVLA for varicose veins.

Long-Term Clinical and Imaging Findings in Patients with Lower Extremity Varicose Veins Treated with Endovenous Laser Treatment: A Follow-Up Study of up to 12 Years.

This study investigates the long-term effectiveness and safety of endovenous laser treatment (EVLT) for chronic venous insufficiency (CVI), a condition commonly caused by dysfunctional valves in the venous circulation system. In this retrospective cohort study, patients underwent EVLT and were followed up for successive short intervals and one last time after a median duration of 9-year postprocedural. Pre- and postprocedure duplex ultrasound was used to assess changes in the great saphenous vein (GSV) diameter, reflux, and saphenofemoral junction incompetence. Quality of life was evaluated using the SF-36 and Aberdeen Varicose Vein Questionnaire (AVVQ). Sixty-eight patients with a mean age of 52.4 ± 12.4 years were enrolled in the study. The mean follow-up time was 8.9 ± 2.1 years, ranging from 5 to 12 years. The mean GSV diameter significantly decreased in all patients (whole group) across proximal (from 5.8 ± 2.3 mm to 4.2 ± 2.1 mm), middle (from 4.7 ± 1.6 mm to 2.8 ± 2.2 mm), and distal (from 4.5 ± 2.3 mm to 2.2 ± 2.2 mm) segments, with P < 0.001. A disease recurrence rate of 33.8% was noted, predominantly in male patients and those with larger middle GSV diameters (OR = 5.2 (95%CI = 1.3-20.4) and OR = 1.5 (95%CI = 1-2.1), respectively). The average follow-up time for patients without recurrence was 8.8 ± 2.1 years. Almost half of the patients without recurrence were followed up for 10 years or more (49%). The efficacy of EVLT in managing varicose veins is demonstrated by its relatively low recurrence rate over a 10-year follow-up period, highlighting EVLT as a viable long-term treatment strategy.

Editor's Choice – Short Term Cost Effectiveness of Radiofrequency Ablation and High Ligation and Stripping for Great Saphenous Vein Incompetence

Superficial venous incompetence (SVI) is a common disease that causes significant quality of life (QoL) impairment. There is a need for more health economic evaluations of SVI treatment. The aim of this study was to perform a cost effectiveness analysis in patients with great saphenous vein (GSV) incompetence comparing radiofrequency ablation (RFA), high ligation/stripping (HL/S), and no treatment/conservative treatment with one year follow up. Randomised controlled trial economic analysis from an ongoing trial; 143 patients (156 limbs) with GSV incompetence (C in CEAP 2 - 6) were included. Treatment was performed with RFA or HL/S. Follow up was performed up to one year using duplex ultrasound, revised venous clinical severity score (r-VCSS), Aberdeen Varicose Vein Questionnaire (AVVQ), and EuroQol-5D-3L (EQ-5D-3L). In total, 78 limbs were treated with RFA and HL/S respectively. No treatment/conservative treatment was assumed to have zero in treatment cost and no treatment benefit. In RFA, one limb had reflux in the GSV after one month and three limbs after one year. In HL/S, two limbs had remaining reflux in the treated area at one month and one year. Both disease severity (r-VCSS, p = .004) and QoL (AVVQ, p = .021 and EQ-5D-3L, p = .028) were significantly improved over time. The QALY gain was 0.21 for RFA and 0.17 for HL/S. The cost per patient was calculated as €1 292 for RFA and €2 303 for HL/S. The cost per QALY (compared with no treatment/conservative treatment) was €6 155 for RFA and €13 549 for HL/S. With added cost for days absent from work the cost per QALY was €7 358 for RFA and €24 197 for HL/S. The cost per QALY for both methods was well below the threshold suggested by Swedish National Board of Health. RFA is more cost effective than HL/S and no treatment/conservative treatment at one year follow up.

Endovenous laser ablation vs phlebectomy of foot varicose veins

ObjectiveThe aim of this study was to compare the outcomes and complications of selected patients treated with endovenous laser ablation (EVLA) or ambulatory phlebectomy for foot varicose veins. MethodsFrom October 2016 to February 2022, selected patients undergoing EVLA (using 1470-nm with radial-slim or bare-tip fibers) or phlebectomy of foot varicose veins for cosmetic indications were analyzed, and the outcomes were compared. Patients were classified according to the Clinical, Etiologic, Anatomical, and Pathophysiological (CEAP) classification. Anatomic criteria provided the basis for the decision to perform EVLA or phlebectomy. Clinical and ultrasound assessments were performed on postoperative days 7, 30, and 90 for visualization of the sapheno-femoral and sapheno-popliteal junctions and the deep venous system. Disease severity was graded with the Venous Clinical Severity Score (VCSS), and quality of life was measured with the Aberdeen Varicose Vein Questionnaire (AVVQ) before and after treatment. Treatment outcomes were evaluated based on changes in VCSS and AVVQ scores. The groups were also compared for procedure-related complications. Data were statistically analyzed in SPSS v. 20.0 using the χ2, Student t test, Mann-Whitney test, Wilcoxon test, and analysis of variance. The results were presented as mean (standard deviation or median (interquartile range). ResultsThe study included 270 feet of 171 patients. Mean patient age was 52.3 (standard deviation, 13.1) years, ranging from 21 to 84 years; 133 (77.8%) were women. Of 270 feet, 113 (41.9%) were treated with EVLA and 157 (58.1%) with phlebectomy. The median preoperative CEAP class was 2 (interquartile range, 2-3) in the phlebectomy and EVLA groups, with no statistically significant difference between the groups (P = .507). Dysesthesia was the most common complication in both groups. Only transient induration was significantly different between EVLA (7.1%) and phlebectomy (0.0%) (P = .001). The two approaches had an equal impact on quality of life and disease severity. ConclusionsTreatment complications were similar in phlebectomy and EVLA and to those previously described in the literature.

Comparison of one-year outcomes and quality of life between endovenous microwave ablation and high ligation and stripping of the great saphenous vein.

The objective of this study is to evaluate and compare the effectiveness of endovenous microwave ablation (EMA) and high ligation and strippingn (HLS) of the great saphenous vein (GSV) in the treatment of varicose veins. We included 182 patients in each EMA and HLS groups. Follow-up outcomes included AVVQ, VCSS, chronic venous insufficiency questionnaire-14 (CIVIQ14) score, clinical recurrence rate of varicose vein treatment, and patient satisfaction during the 1-year follow-up period. At the 1-year follow-up, no significant difference was found in the clinical recurrence rate of varicose veins between the EMA and HLS groups (p = .75). The duration of the operation and the length of hospital stay for patients in the EMA group was shorter than that for the HLS group (p < .01). The Aberdeen Varicose Vein Questionnaire (AVVQ), Venous Clinical Severity Score (VCSS) score, and ecchymosis were lower for patients who underwent EMA surgery (p < .01). Our research results confirm that EMA improves patients' quality of life with lower limb varicose veins, with EMA showing higher patient satisfaction.

Clinical Efficacy of a Modified Surgical Procedure in the Treatment of Incompetent Great Saphenous Veins.

The aim of this study was to evaluate the clinical efficacy of a modified surgical procedure for the treatment of varicose veins. This retrospective analysis was conducted on lower extremities with symptomatic great saphenous vein (GSV) incompetence that underwent stripping from the groin to the knee, with preservation of the superficial epigastric vein (SEV), between January 2015 and April 2022. Follow-up assessments were performed using Doppler ultrasound, Venous Clinical Severity Score (VCSS), and the Aberdeen Varicose Vein Questionnaire (AVVQ) at 6 and 12 months after surgery. The study included 179 limbs from 120 patients (47 men and 73 women). The mean patient age was 56.5 years (range, 20-78 years), and the distribution of preoperative Clinical-Etiology-Anatomy-Pathophysiology clinical classes was 8% C0-C1, 88% C2, and 4% C3-C6. The preoperative diameter of the saphenofemoral confluence averaged 6.9 mm (range, 2.7-15.8 mm). After a mean postoperative follow-up period of 24 months, evidence of neovascularization around the stump of the saphenofemoral junction (SFJ) was observed in 2 limbs (1.1%). Additionally, varicose vein recurrence was found in 1 limb (0.6%) and was associated with an incompetent thigh perforator. At postoperative follow- up, both VCSS and AVVQ scores were significantly lower than the preoperative scores. Modified surgical treatment of GSV incompetence, involving preservation of the SEV and stripping of a short segment up to the knee, demonstrated favorable clinical results in terms of postoperative complication rate, neovascularization rate around the SFJ stump, varicose vein recurrence rate, and improvement in lower extremity symptoms.

COMPARISON BETWEEN CONVENTIONAL HIGH LIGATION AND STRIPPING AND RADIOFREQUENCY ABLATION FOR GREAT SAPHENOUS VARICOSE VEINS

The prospective study was conducted from December 2022 to May 2023 to assess patient-based, radiological, and clinical outcomes after conventional surgery and radiofrequency ablation for great saphenous varicose veins. Patients were randomly divided to undergo conventional surgery or RFA. American Society of Anesthesiologists fitness grade, Venous Disability Score (VDS), Total Clinical Severity Score (TCSS), Michael's, and CEAP clinical classes were recorded. VEINES-QoL/Sym questionnaire and Aberdeen Varicose Vein Questionnaire were used to estimate baseline QoL. Patients were called for follow-up at the end of 1st and 5th week. The study was conducted on a total of 110 patients. Patients were randomly divided; 57 underwent RFA, and 53 underwent conventional surgery. Results showed that the difference between both groups regarding anesthesia induction, recovery, and discharge from surgery was insignificant. RFA had significantly longer total theater time compared to conventional surgery. Duplex imaging showed that RFA resulted in successful ablation except in two cases where veins had segmental brisk flow. These cases were retreated successfully. Conventional surgery only had the problem of incomplete stripping (6 cases). Post-operative pain, bruising, and the need for analgesia were significantly higher following conservative surgery. Patients in the RFA group returned to work and normal activities more quickly than the conventional surgery group. It is concluded that RFA had a longer intervention time but significantly better outcomes than conventional surgery.

Quantifiable remaining reflux 1 year after treatment of superficial venous incompetence is associated with impaired clinical outcome

ObjectiveRemaining symptoms after treatment of superficial venous incompetence is a common problem. Duplex ultrasound is often used during follow-up, but does not permit an overall quantification of venous function. We have developed a plethysmographic method using occlusion cuffs for separation of superficial and deep venous reflux. By assessing the superficial component it is possible to quantify a potential suboptimal hemodynamic treatment in patients with superficial venous incompetence. The aim was to examine whether patients with hemodynamically quantifiable remaining reflux after treatment experience impaired clinical outcomes. MethodsThis single-center prospective cohort study evaluated 156 limbs with great saphenous vein incompetence treated with radiofrequency ablation or high ligation and stripping. Duplex ultrasound and strain-gauge plethysmography (SGP) with and without selective superficial occlusion were performed before and one-year after treatment. Time taken (seconds) to reach 50% of the venous volume (T50) was evaluated. A difference in the T50of >5 seconds between postoperative strain-gauge plethysmography with and without superficial occlusion was defined as remaining reflux. The Venous Clinical Severity Score (VCSS) and Aberdeen Varicose Vein Questionnaire (AVVQ) were evaluated and compared between patients with and without remaining reflux. Multivariable logistic regression was used to evaluate risk factors for remaining plethysmographic reflux. ResultsIn all patients, median (25th, 75th percentile) T50 increased preoperatively from 7 seconds (3, 12 seconds) to 17 seconds (11, 28 seconds) (P < .001) 1 year after treatment. The VCSS and AVVQ were reduced (VCSS, 8.0 [6.0, 10.0] vs 3.0 [1.0, 5.0] [P < .001]; AVVQ, 21.8 [15.8, 32.1] vs 6.4 [2.2, 11.0] [P < .001]). Of the 156 limbs, 87 (56%) demonstrated remaining reflux 1 year after treatment. Patients with remaining plethysmographic reflux displayed higher median (25th, 75th percentile) VCSS (3.0 [2.0, 5.0] vs 2.0 [1.0, 4.0]; P = .012) and AVVQ (7.5 [2.7, 14.9] vs 4.7 [1.6, 9.2]; P = .025). Multivariate logistic regression showed that higher preoperative C in the Clinical Etiology Anatomy Pathophysiology classification (CEAP) (odds ratio [OR], 2.9 [95% confidence interval [CI], 1.34-6.46), age (OR, 1.03; 95% CI, 1.001-1.065), small saphenous vein incompetence (OR, 4.2; 95% CI, 1.30-13.73) and postoperative great saphenous vein reflux below the treated area (OR, 2.16; 95% CI, 1.02-4.56) were significant risk factors for remaining plethysmographic reflux. ConclusionsA majority of treated limbs showed quantifiable reflux 1 year after intervention and these patients displayed worse patient related outcomes assessed with the VCSS and AVVQ. Remaining plethysmographic reflux was associated with preoperative small saphenous vein incompetence and reflux below the treated area as well as advanced age and higher C in CEAP.

A comparison of patient-reported outcome measures following technical success and technical failure in the treatment of great saphenous vein incompetence using ClariVein: A subanalysis of a multicenter randomized controlled trial comparing 2% and 3% polidocanol.

This study aimed to compare patient-reported outcomes after technical success (TS) and technical failure (TF) in treating great saphenous vein incompetence (GSV) with ClariVein. A subanalysis of a previous trial was conducted on symptomatic GSV incompetence patients who received ClariVein treatment with 2% or 3% polidocanol (POL) and were followed for 6months. Blinding was implemented for observers and patients, and data from both POL groups were combined. TS was defined as at least 85% occlusion of the treated vein, while TF indicated failure to meet TS criteria. Secondary outcomes included Venous Clinical Severity Score (VCSS), Aberdeen Varicose Vein Questionnaire (AVVQ), and Short-Form 36 Health Survey Questionnaire (SF-36). Among the 364 patients included, the TS rate was 64.5%. Comparison of VCSS, AVVQ, and SF-36 scores between TS and TF groups did not yield significant differences. This study indicates no significant variation in VCSS, AVVQ, and SF-36 scores between patients experiencing TS and TF following ClariVein treatment for GSV insufficiency.

Endovenous Microwave Ablation Versus Radiofrequency Ablation for the Treatment of Lower Limb Varicose Veins

This study aimed to retrospectively compare the clinical outcomes of endovenous microwave versus radiofrequency ablation combined with foam sclerotherapy in patients with lower limb varicose veins. We identified patients with lower limb varicose veins treated with endovenous microwave ablation or radiofrequency ablation with foam sclerotherapy between January 2018 and June 2021 at our institution. Patients were followed-up for 12months. Clinical results, including the pre-post-Aberdeen Varicose Vein Questionnaire and post-Aberdeen Varicose Vein Questionnaire and Venous Clinical Severity Score, were compared. Complications were documented and treated accordingly. We included 287 cases (295 limbs total; endovenous microwave ablation+foam sclerosing agent: n=142, 146 limbs; radiofrequency ablation+foam sclerosing agent: n=145, 149 limbs). The operative time was shorter for endovenous microwave ablation than radiofrequency ablation (42.58±15.62min vs. 65.46±24.38min, P<0.05); however, other procedural parameters did not differ. Furthermore, hospitalization costs for endovenous microwave ablation were lower than those for radiofrequency ablation (21,063.74±850.47 yuan vs. 23,312.40±1,035.86 yuan, P<0.05). At the 12-month follow-up, the great saphenous vein closure rate was similar in both groups (endovenous microwave ablation, 97% [142/146] vs. radiofrequency ablation, 98% [146/149]; P>0.05). Additionally, the satisfaction or incidence rates of complications were not different among the groups. In both groups, the Aberdeen Varicose Vein Questionnaire and Venous Clinical Severity Score values were significantly lower 12months postsurgery than before surgery; however, the postoperative values did not differ. Endovenous microwave ablation effectively treated lower limb varicose veins, with similar short-term effects as radiofrequency ablation. Moreover, it had a shorter operative time and was less expensive than endovenous radiofrequency ablation.

One Year Follow-Up of Endovascular Microwave Ablation and Concomitant Foam Sclerotherapy in the Treatment of Primary Small Saphenous Vein Insufficiency

In the last decade, the microwave ablation (MWA) catheter specifically for treating lower extremity varicose veins has become popular. However, imited data is available on the efficacy, analysis, and evaluation of endovenous microwave ablation (EMWA) in treating SSV insufficiency. This study evaluated the feasibility, safety, and 1-year outcomes of endovenous microwave ablation and concomitant foam sclerotherapy of primary small saphenous vein (SSV) insufficiency. Our team carried out a single-center, retrospective analysis of 24 patients treated with endovenous microwave ablation and concomitant foam sclerotherapy for primary SSV insufficiency. All operations were performed using a microwave ablation catheter and polidocanol for the trunk and branches of the SSV, respectively. The SSV occlusion rate was assessed at the 6- and 12-month follow-up examinations using duplex ultrasound. Secondary outcomes included the Clinical, Etiological, Anatomical, Pathophysiological (CEAP) clinical class; Venous Clinical Severity Score (VCSS); Aberdeen Varicose Vein Questionnaire (AVVQ); periprocedural pain; and complications. 100% of the cases have been technically successful. At the 6-month follow-up, all treated SSVs were occluded. The 12-month assessment duplex doppler showed anatomical success in patients with 95.8% (95% confidence interval, 0.756-0.994). The CEAP clinical class, VCSS, and the AVVQ had decreased significantly at the 6-, and 12-month follow-up, respectively. Endovenous microwave ablation and concomitant foam sclerotherapy is a feasible and effective technique for treating SSV insufficiency.

O018 Determining the relationships between venous reflux patterns, clinical severity, and health-related quality of life

Abstract Introduction Various classification systems have been created to describe the anatomical distribution of venous reflux, including the VEIN-TERM and Clinical-Etiology-Anatomy-Pathophysiology (CEAP) classification. It is still unclear whether different reflux patterns correlate with health-related quality of life (HRQoL) and clinical severity. Methods Some 507 chronic venous disease patients and 105 asymptomatic controls underwent duplex ultrasound assessment. Patients were stratified according to VEIN-TERM and the CEAP classification systems. The Aberdeen Varicose Vein Questionnaire (AVVQ) score was used to compare HRQoL and the Venous Clinical Severity Score (VCSS) was used to compare clinical severity between groups. Results Patients were significantly older than controls (p&amp;lt;0.00001). All VEIN-TERM reflux patterns had significantly greater VCSS than no reflux (p&amp;lt;0.001). Superficial axial and combined axial reflux were associated with significantly greater VCSS than superficial segmental reflux (p&amp;lt;0.001, p=0.042 respectively). All VEIN-TERM reflux types had significantly worse AVVQ scores than no reflux (p&amp;lt;0.03). However, there were no significant differences in AVVQ scores across all VEIN-TERM reflux patterns. Most CEAP reflux patterns had increased VCSS and worse AVVQ scores when compared to no reflux (all p&amp;lt;0.05), except for deep reflux, and deep and perforator reflux only. The deep, superficial and perforator reflux group had significantly higher VCSS (p=0.013) and AVVQ (p&amp;lt;0.001) versus the superficial reflux only group. Conclusion When compared to no reflux, both classification systems show associations of any reflux pattern with worse VCSS and AVVQ scores. Combined reflux patterns were associated with the greatest clinical severity and worst HRQoL scores.

Combined effect of yoga and naturopathy in uncomplicated varicose vein disease – a prospective randomized controlled trial

BackgroundThough the treatment of uncomplicated varicose vein (UVV) might prevent late complications such as skin change or ulceration, but, there are limited studies available to justify this concept. Yoga and Naturopathy being a proficient tool in managing non communicable diseases including many cardiovascular diseases; no attempt was made to study its potential effect in Varicose Vein diseases. ObjectiveThe present study aims to study the combination of Yoga and Naturopathy in uncomplicated varicose vein patients. Materials and methods50 UVV participants were prospectively recruited and randomly divided into two groups, Experimental and Active control groups. Both the groups practiced their respective interventions, and follow up was done after 1 and 3 months of active intervention. Finally study was completed with 46 participants (2 dropouts in each groups). The sample size was calculated based on the previous study, considering power as 0.8 and ‘α’ as 0.05, using ‘G’ power software. The variables such as Body weight, BMI, Systolic blood pressure (SBP), Diastolic blood pressure (DBP), Heart rate (HR), high-sensitivity C-reactive protein (hs-CRP), homocysteine (HCy) were recorded before and after the intervention, but Aberdeen Varicose Vein Questionnaire (AVVQ) and Visual analogue heaviness scale (VAHS) were recorded on 60 and 120 days of the follow up in addition to active intervention period. ResultsThere was a significant decrease in hs-CRP (p < 0.05) in the experimental group as compared to the control group. Body weight, BMI, SBP, HR, hs-CRP, HCy (p < 0.001) and DBP (p < 0.05) significantly decreases following the Combined Yoga and Naturopathy (CYN) intervention for a month in the experimental group. Also, the AVVQ (p < 0.01) and VAHS (p < 0.05) decreases following active intervention and two consecutive follow up. No adverse event was noted during or after the trial. ConclusionThe combined effect of Yoga and Naturopathy reduced blood pressure and inflammatory markers suggestive of potential of recovery in inflammation in the endothelial tissue of the microvascular system in UVV patients.

Translation and adaptation to Spanish of Aberdeen varicose veins questionnaire

The purpose of the study is to translate the Aberdeen Varicose Vein Questionnaire (AVVQ) into Spanish and evaluate the feasibility and reliability of the Spanish-translated AVVQ in patients with chronic venous disease. Reliability was assessed by test and retest of the Spanish translated AVVQ in a sample of 77 patients. The questionnaires were answered within a 2-week interval. There was a 100% test and retest response. The AVVQ showed 6.5% of missing responses. Cronbach's alpha was 0.71 indicating an adequate level of internal consistency. Spearman's rho showed a significant strong association between test and retest scores (rho = 0.84, p < 0.0001). The Spanish-translated AVVQ is a reliable tool in our daily clinical practice in order to measure the impact of venous disease in the quality of life.

Six Year Extension Study of Patients From a Randomised Clinical Trial Comparing Venefit, Radiofrequency Induced Thermal Therapy, and Endovenous Radiofrequency Ablation for Treatment of Incompetent Great Saphenous Veins

To compare long term outcomes after great saphenous vein (GSV) treatment with three radiofrequency (RF) thermal devices: Venefit (Closurefast), Radiofrequency Induced Thermal Therapy (RFITT), and Endovenous Radiofrequency (EVRF). A 72 month follow up of patients who were treated in the randomised 3RF study. A total of 172 participants from the 3RF study were invited to take part in a single visit, long term, follow up study. Failure of GSV closure was assessed with duplex ultrasound (DUS) and constituted the primary outcome. Patients completed questionnaires for secondary outcomes: Aberdeen Varicose Vein Questionnaire (AVVQ), Euroqol 5D (EQ-5D), and patient reported varicose veins measured by counting vein occupying boxes in AVVQ question 1. Twenty-two patients (12%) had already been re-treated. Of the remainder, 13 (7%) could not be contacted, 20 (11%) declined invitation, and one did not consent. Therefore, 116 (64%) and 95 (53%) participants completed questionnaires and DUS, respectively. Failure of GSV closure on 72 month DUS was 16%, 21%, and 37% for Venefit, RFITT, and EVRF, respectively (p= .14), whilst outcomes for all failures were 14%, 17%, and 44% (p < .001) (Venefit vs. EVRF: p < .001; RFITT vs. EVRF: p < .001; and Venefit vs. RFITT: p= .63). There were no between group differences in AVVQ or EQ-5D scores. Rates of patient reported presence of any varicose veins were high for all groups (97%, 92%, and 97% after Venefit, RFITT, and EVRF, respectively; p= .48). The EVRF treated participants reported more extensive recurrence than the Venefit and RFITT participants (p= .008). Long term technical outcomes after RF ablation for GSV varicose veins were significantly better after Venefit and RFITT compared with EVRF treatment. However, quality of life scores showed no differences after 72 months. Rates of patient reporting any varicose veins were high for all treatments. gov Identifier: NCT04720027.

Clinical outcomes following mechanochemical ablation of superficial venous incompetence compared with endothermal ablation: meta-analysis.

Mechanochemical ablation (MOCA) is an alternative method to endovenous thermal ablation (EVTA) for the treatment of superficial venous incompetence that does not require tumescent anaesthesia. The aim of this study was to compare the outcomes from RCTs of MOCA versus EVTA. A search was conducted in MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL). Meta-analysis inclusion was restricted to RCTs comparing MOCA against EVTA. Outcomes included anatomical occlusion rate, disease-specific quality of life using the Aberdeen Varicose Vein Questionnaire, procedural and postprocedural pain, and rates of venous thromboembolism. Four RCTs were included in the meta-analysis comprising 654 patients. The anatomical occlusion rate at 1 year was lower after MOCA than EVTA (risk ratio 0.85, 95 per cent c.i. 0.78 to 0.91; P < 0.001). No significant differences were detected in procedural pain (mean difference -3.25, -14.25 to 7.74; P = 0.560) or postprocedural pain (mean difference -0.63, -2.15 to 0.89; P = 0.420). There were no significant differences in Aberdeen Varicose Vein Questionnaire score at 1 year (mean difference 0.06, -0.50 to 0.62; P = 0.830) or in incidence of venous thromboembolism (risk ratio 0.72, 95 per cent c.i. 0.14 to 3.61; P = 0.690). The rate of successful anatomical occlusion after MOCA is significantly lower than that after EVTA, but there is no difference in procedural and postprocedural pain between the two interventions. Long-term data are required to assess the impact of the reduced vein occlusion rate on clinical outcomes such as quality of life and reintervention.

Early results of cyanoacrylate adhesive ablation versus laser ablation for the treatment of great saphenous vein insufficiency in the Chinese mainland population.

In this study, we present our early outcomes of cyanoacrylate ablation (CA) versus endovenous laser ablation (EVLA) for the treatment of great saphenous vein (GSV) insufficiency in the Chinese mainland population. We retrospectively analyzed 108 patients (53 patients in the CA group and 55 patients in the EVLA group) with GSV insufficiency who were treated with CA and EVLA between May 2020 and May 2021. The Venous Clinical Severity Score and Aberdeen Varicose Vein Questionnaire were used to assess clinical symptoms and quality of life, respectively. Total closure rates and procedure-related adverse events were also recorded in both groups. There was no significant difference between patients treated with CA or EVLA in terms of demographic and clinical characteristics. The average procedure time was 17min in the CA group and 35min in the EVLA group (p < 0.001). The CA group had lower pain scores during the procedure and 3days afterward than the EVLA group (p < 0.001). At month 12, the CA group had a 90.4% closure rate, while the EVLA group had an 83.0% closure rate, with no significant difference between the two groups (p > 0.05). There was no significant difference in the Venous Clinical Severity Score or Aberdeen Varicose Vein Questionnaire score between the groups (p > 0.05). During follow-up, neither group experienced any significant adverse events, such as pulmonary embolism or deep venous thrombosis. The incidence of ecchymosis and paresthesia was significantly lower in the CA group than in the EVLA group (p < 0.05). Cyanoacrylate ablation has a high feasibility profile and is an effective approach to accomplish complete GSV target vein closure at early follow-up in the Chinese patients. Compared to EVLA, the improvement in quality-of-life outcomes is also sustained and similar, with less pain and fewer complications due to the absence of tumescence anesthesia and postprocedural compression stockings.

Evaluation of mid-term results in our patients treated with N-Butyl cyanoacrylate embolization in saphenous vein insufficiency

Aim: The aim of this study is to present our mid-term results obtained from patients with advanced saphenous vein insufficiency treated with N-butyl cyanoacrylate embolization (CAE). Material and Methods: In the present study, we included 1013 patients who were treated with CAE because of moderate and severe saphenous vein insufficiency in Eskişehir Osmangazi University Medical Faculty Hospital Cardiovascular Surgery Clinic between January 2015 and November 2019. The patients were rechecked at 1st, 6th, 12th, 24th and 36th months. Venous Clinical Severity Score (VCSS) and Aberdeen Varicose Vein Questionnaire (AVVQ) results recorded at preoperative and postoperativee period. Doppler ultrasonography (USG) was performed to all patients in all controls. The absence of re-canalized flow in Doppler USG was accepted as the success of the procedure. Results: The mean age of 1013 patients was 51.27±14.30 years (448 men (44.2%) and 565 women (55.8%)). The average procedure time was 12.4±2.1 minutes, the average amount of CA used in the procedure was 1.6 ml (min: 1 ml - max: 2ml). In outpatient controls, complication rates was low, thrombophlebitis occurred in 17 patients (1.7%) and ecchymosis occurred in 9 patients (0.9%). The occlusion rate was 97.6% according to the 1-year follow-up results and 93.3% according to the 3-year follow-up results. The decrease in VCSS and AVVQ scores was statistically significant when the preoperative and postoperative period results compared (p&lt;.05). Conclusion: In the present study, we think that CAE is a safely and effective treatment method for saphenous vein insufficiency. It has low complication, high occlusion rates and provides better comfort to the patients.

SA37 Cultural Adaptation and Sociometric Analysis of Aberdeen Varicose Vein Questionnaire

The purpose of our study was to translate and adapt the Aberdeen Varicose Vein Questionnaire (AVVQ) into Hungarian language, and to investigate the sociometric properties of the Hungarian AVVQ, as well as to assess the health-related quality of life of patients suffering from varicose vein disease.
