Introduction: Varicose veins (VV) negatively impact quality of life (QoL) and have risks of major complications including bleeding, ulceration and phlebitis. During the COVID-19 pandemic, the VSGBI (Vascular Society of Great Britain and Ireland) and GIRFT (Get It Right First Time) classified VVs as lowest priority for intervention.

Objective: This study aims to determine harm caused and the impact on the QoL on patients waiting for their VVs procedures for more than 1 year.

Methods: This was a prospective study conducted at the Norfolk and Norwich University Hospital (NNUH). Patients with VVs awaiting intervention for >1 year were included in the study. Patients with CEAP C6 disease were considered to be too high risk to be invited for treatment during the Covid-19 pandemic. Patients were sent QoL questionnaires and underwent a telephone consultation to assess harm. Both generic (EQ-VAS and EQ-5D) and disease-specific (AVVQ and CIVIQ-14) instruments were utilised. There were no control groups available for comparison.

Results: 275 patients were identified (37.1% male) with median time on waiting list of 60 weeks (IQR 56-65). 19 patients (6.9%) came to major harm, including phlebitis (3.6%), bleeding (1.8%) and ulceration (1.8%). Fifty-two patients (18.9%) had minor harm, including worsening pain (12.7%) and swelling (6.2%). 6.9% reported psychological harm. Rising CEAP stage was also associated with worsening level of harm in patients with C5-6 disease (p < 0.0001). Only 8.7% stated they would decline surgery during the pandemic. 104 QoL questionnaires were returned. Median EQ-VAS and EQ-5D was 75 (IQR: 60-85) and 0.685 (0.566-0.761), respectively. Median AVVQ score was 23.2 (14.9-31.0) and CIVIQ-14 score was 33 (21-44).ConclusionsThis study highlights the impact of delaying VVs surgery during a pandemic. A significant rate of both major and minor as well as psychological harm was reported. In addition, VVs had a significant detriment to quality of life.

Objectives: It is unclear whether reflux time independently correlates with severity of symptoms in patients with great saphenous vein reflux.

Methods: Eighty patients (mean age 64+/-12.7 years, 56% female) undergoing great saphenous vein (GSV) ablation for symptomatic reflux were assessed prospectively. Fifty-seven underwent ablation with radiofrequency, 23 with cyanoacrylate adhesive. Venous clinical severity score (VCSS) was assessed at, or prior to the time of ablation. The highest reflux time in the GSV was selected.

Results: VCSS values ranged from 2 to 20 (median 7). Mean reflux time was 5.3 s (+/-3.3). The Spearman rank correlation yielded a value of rs = -0.123, p (2-tailed) = .279, which was not significant. The patients with concomitant deep vein reflux had higher VCSS (p < .05). Analysis of patients with only superficial vein reflux (n = 45) also demonstrated a poor correlation between VCSS and reflux time (rs = -0.051, p (2-tailed) = .741).

Conclusion: This prospective study did not demonstrate a correlation between reflux time and VCSS.

Purpose: This study evaluated the results of polidocanol sclerotherapy in the treatment of venous malformations (VM) including patient satisfaction, perceived improvement, and predictors of satisfaction.

Material and method: Patients with VM that underwent polidocanol foam sclerotherapy between June 2013 and July 2021 in a single center were retrospectively evaluated. Patient demographics, VM, and treatment characteristics were analyzed. Patient-reported outcomes and satisfaction were analyzed with a questionnaire.

Results: This study included 232 (136, 58.6%, female) patients. The mean age was 24.49 ± 12.45 years (range 3-72). The clinical response rate was 82.3%. The rate of satisfaction was 82.3%, and 116 (50%) patients were significantly satisfied. There were no major complications. Clinical response and VM margin were related to satisfaction (p < 0.01, p = 0.012, respectively). Clinical response to pretreatment swelling was related to significant satisfaction (p = 0.02).

Conclusion: Polidocanol sclerotherapy was safe and effective in VM treatment with high satisfaction and low complication rates.

Introduction: This study investigated the current status of patients' knowledge and clinical compliance with ankle pump exercises in order to better enhance patient education and improve patient compliance with ankle pump exercises.

Methods: A cross-sectional survey of the current status of ankle pump exercise awareness and compliance was conducted using a self-designed questionnaire. The questionnaire consisted of a general demographic information questionnaire, a questionnaire on patients' perceptions of ankle pump exercise and a compliance questionnaire.

Results: A total of 2,203 patients from 53 clinical departments participated in this survey. 87.8% of patients considered ankle pump exercise important, 92.1% could grasp the knowledge of ankle pump exercise, 48.5% could self-monitor and exercise daily as instructed, 81.5% of health care workers would often supervise patients to complete ankle pump exercise, poor self-control (34.6%), lack of physical strength (21.1%) and perceived hassle (18.9%) were the top 3 factors contributing to patients' inability to complete the ankle pump exercise. Regression analysis showed that the factors influencing patients' compliance with the ankle pump exercise were literacy, economic level, number of comorbidities and caprini risk class (p < .05).

Conclusion: The patient's cognition of ankle pump exercise is good, but the compliance needs to be improved. It is suggested that the compliance of ankle pump exercise in hospitalized patients should be improved in the future to reduce the incidence of Venous thromboembolism.

Objectives: Aim was to report a prospective two-centre Singaporean experience using Endovenous Microwave Ablation (EMA) to treat symptomatic primary great saphenous vein reflux. We evaluated 1-year safety, efficacy and patient satisfaction.

Methods: 50 patients (63 limbs; 29 females; mean age 58.0 ± 12.1 years) were included. Patients were reviewed at 2-weeks, 3-, 6- and 12-months and underwent Duplex ultrasound assessment. Three quality of life (QoL) questionnaires were completed.

Results: The truncal closure rates at 2-weeks, 3-, 6- and 12-months were 63/63 (100%), 59/59 (100%), 58/58 (100%) and 59/60 (98.3%), respectively. There was 100% technical success and no serious adverse events. There were sustained improvement of QoL questionnaire scores from 2 weeks to 12 months.

Conclusion: EMA is a safe and efficacious venous ablative technology at 12 months and is associated with a high rate of target vein occlusion and sustained QoL improvement.

Aim: This study examines the interactions between central venous and cardiac sonomorphologies to explain the mechanism of impaired heart relaxation in patients with varicose veins of lower extremities.

Material and methods: Part 1: We performed retrospective analysis of influences of inferior vena cava (IVC) diameters on tricuspid and mitral inflow and annular velocities in 64 patients with primary varicose veins. Part 2: We compared IVC diameters and IVC collapsibility index (IVC CI) in patients with varicose veins with normal values.

Results: We found a significant positive influence of an increase in maximal expiratory and minimal inspiratory IVC diameters on mitral and tricuspid early annular velocities or e^'-waves (p-values < .008), inflow velocities or E-waves (p-values < .05) and early to late inflow E/A ratios (p-values < .01). Less influenced by the changes in venous biometry (p-values > .05) were late mitral and tricuspid inflow, annular and systolic velocities (A-, a^'-, s-waves).Expiratory and inspiratory diameters in patients with varicose veins were significantly smaller (p-values < .05 expiratory; < .0001 inspiratory), and IVC CI was significantly higher (p-values < .0001) than the normal values.

Conclusion: Chronic venous disease impairs the function and the morphology of the entire inferior caval system and the heart. Impaired relaxation of the heart in patients with varicose veins is the result of two factors: (1) impaired venous return resulting in the low central venous pressure and the low early diastolic cardiac inflow; (2) structural changes in the heart resulting in the compensatory increased late diastolic cardiac inflow. Increase in central venous pressure (IVC diameters) and early diastolic cardiac inflow (E-waves), accompanied by unchanged myocardial response (e^'-wave) can serve as marker for return to normal physiology.

Objective: To evaluate the incidence of anomalies in the superficial venous system in lower limb.

Method: Triplex ultrasonography in clinically suspected cases of acute or chronic venous disease or congenital malformation was performed on 3189 lower limbs in 2000 patients (bilateral in 1189 and unilateral in 811) from Jan 2020 to Dec 2020.

Result: (1) Anomalies of great saphenous vein were observed in 496 cases (15.5%), (2) Anomalies of short saphenous vein were observed in 760 cases (23.8%), (3) Anomalies of accessory saphenous veins were seen in 984 (30.88%), 1501 (47%), 1068 (33.5%) and 774 (24.25%) corresponding to the anterior, posterior, lateral systems and posterior accessory vein of leg, respectively.

Conclusion: Anomalies of the superficial venous system in lower limb are very common and must be reported in every doppler study. These anomalous veins may be the cause for residual or recurrent disease in chronic venous insufficiency, which warrants further research.
