RESUMO
PURPOSE: Hospitalisation and surgery are major risk factors for venous thromboembolism (VTE). Intermittent pneumatic compression (IPC) and graduated compression stockings (GCS) are common mechanical prophylaxis devices used to prevent VTE. This review compares the safety and efficacy of IPC and GCS used singularly and in combination for surgical patients. METHODS: Ovid Medline and Pubmed were searched in a systematic review of the literature, and relevant articles were assessed against eligibility criteria for inclusion along PRISMA guidelines. RESULTS: This review is a narrative description and critical analysis of available evidence. Fourteen articles were included in this review after meeting the criteria. Results of seven studies comparing the efficacy of IPC versus GCS had high heterogeneity but overall suggested IPC was superior to GCS. A further seven studies compared the combination of IPC and GCS versus GCS alone, the results of which suggest that combination mechanical prophylaxis may be superior to GCS alone in high-risk patients. No studies compared combination therapy to IPC alone. IPC appeared to have a superior safety profile, although it had a worse compliance rate and the quality of evidence was poor. The addition of pharmacological prophylaxis may make mechanical prophylaxis superfluous in the post-operative setting. CONCLUSION: IPC may be superior to GCS when used as a single prophylactic device. A combination of IPC and GCS may be more efficacious than GCS alone for high-risk patients. Further high-quality research is needed focusing on clinical relevance, safety and comparing combination mechanical prophylaxis to IPC alone, particularly in high-risk surgical settings when pharmacological prophylaxis is contraindicated.

OBJECTIVES: Graduated compression stocking (GCS) is one of the mechanical prophylaxes commonly used for deep vein thrombosis (DVT). The present study was designed to observe the effects of graduated compression stockings on the vein deformation and hemodynamics of lower limbs in patients awaiting total hip arthroplasty (THA). METHODS: The lower extremity veins of 22 patients awaiting THA were examined by ultrasound, when they rested in supine position with or without thigh-length GCS. The deformation parameters we measured included antero-posterior (AP) diameters, latero-medial (LM) diameters, and cross-sectional area (CSA) of great saphenous vein (GSV), posterior tibial vein (PTV), popliteal vein (PV), gastrocnemius vein (GV), and superficial femoral vein (SFV). We measured peak velocity and mean velocity of GSV, common femoral vein (CFV), junction of GSV and CFV to represent for hemodynamics of veins. RESULTS: Significant compression was observed in almost all measured veins with the use of thigh-length GCS, while it was unable to significantly compress GSV in latero-medial diameter. The mean latero-medial diameter reductions for GSV, PTV, GV, PV and SFV were 19.4, 30.2, 43.2, 29.7 and 20.4%, respectively. GCS significantly compressed antero-posterior diameter of GSV, PTV, GV, PV and SFV by 43.4, 33.3, 42.1, 37.5, and 27.8%, respectively. The mean reduction of cross-section area was 44.8% for GSV, 49.6% for PTV, 60.0% for GV, 57.4% for PV, and 36.2% for FV. No significant changes were observed in the mean blood velocity of GSV, CFV, and junction. GCS was able to significantly reduce peak velocity of CFV (17.6 ± 5.6 cm/s to 16.1 ± 6.0 cm/s) and junction (23.3 ± 9.5 cm/s to 21.3 ± 9.7 cm/s), while it did not change the peak velocity of GSV. CONCLUSION: Thigh-length GCS is sufficient to compress lower extremity veins in patients awaiting THA in supine position with the greatest compression in GV, while it was unable to significantly increase blood velocity of common femoral vein or GSV. GCS may prevent DVT through more than simply increasing blood flow. Further studies are needed to determine the specific effects of GCS.

OBJECTIVES: To analyze the changes of lower limb hemodynamics parameters before and after wearing graduated compression stockings (GCS) during ankle pump exercise in patients preparing for arthroplastic surgery. METHOD: The leg veins of 16 patients awaiting arthroplasty were analyzed using a Sonosite M-Turbo ultrasound system during ankle pump exercise with or without GCS. The age of them was 70 ± 7 years (mean ± SD) (range 56-82 years) and body mass index was 25.8 ± 3.0 kg/m2 (range 18.0-30.5 kg/m2). Measured data including the cross-sectional area (CSA), anteroposterior (AP) diameter and lateromedial (LM) diameter of the soleus vein (SV), posterior tibial vein (PTV) and great saphenous vein (GSV). Additionally, the peak velocities of femoral vein (FV) were also measured. RESULTS: GCS could significantly decrease the cross-sectional area of SV, PTV and GSV in supine position at rest and maximum ankle plantar flexion. But the compression effect of GCS to SV and GSV was not observed during maximum ankle dorsiflexion. It was found that GCS application reduced the peak flow velocity of the femoral vein from 61.85 cm/s (95% CI = 50.94-72.75 cm/s) to 38.01 cm/s (95% CI = 28.42-47.59 cm/s) (P < 0.001) during ankle plantar flexion and decreased the femoral vein in these patients from 80.65 cm/s (95% CI = 70.37-90.92 cm/s) to 51.15 cm/s (95% CI = 42.58-59.73 cm/s) (P < 0.001) during ankle dorsiflexion. But this effect was not significant in supine position at rest. CONCLUSIONS: GCS could significantly reduce the peak flow velocity of the femoral vein during ankle pump exercise in the patients preparing for arthroplastic surgery.

OBJECTIVES: This study was designed to explore venous deformation of the lower extremities and the changes in venous hemodynamics in supine position before and after wearing graduated elastic stockings in patients awaiting total knee arthroplasty (TKA). METHOD: The leg veins of 21 elderly patients awaiting TKA were imaged in the supine position with and without knee-length graduated compression stockings (GCS) according to a fixed protocol. Measured parameters including the lateromedial (LM) diameter, anteroposterior (AP) diameter, and cross-sectional area (CSA) of the great saphenous vein (GSV), gastrocnemius vein (GV), soleus vein (SV), posterior tibial vein (PTV), fibular vein (FV), and anterior tibial vein (ATV). In addition, the mean and maximum velocities of the popliteal vein (PV) and superficial femoral vein (FSV) were measured. RESULTS: GCS-related compression was observed for all the measured veins. Maximal reduction was observed for the GV and SV, whereas the GSV exhibited the lowest degree of GCS-related compression. The mean cross-sectional area reduction values associated with GCS were 33.1 ± 41.2 % for the GSV, 94.8 ± 11.1 % for the GV, and 85.6 ± 20.3 % for the SV, while the mean reduction of anteroposterior diameter was 18.1 ± 34.5 % for the GSV, 89.0 ± 22.5 % for the GV, and 72.9 ± 35.1 % for the SV, and the mean reduction of the lateromedial diameter was 25.9 ± 36.4 % for the GSV, 89.6 ± 19.6 % for the GV, 78.2 ± 28.3 % for the SV. No significant GCS-related changes in blood velocity in the superficial femoral veins or popliteal veins were detected. CONCLUSIONS: For elderly patients awaiting TKA, knee-length GCS can significantly reduce calf vein dilation while at rest in the supine position, with the greatest reductions being observed for the soleus and gastrocnemius veins. These data might help provide a theoretical basis for the GCS in reducing incidence of deep vein thrombosis in patients undergoing TKA.

BACKGROUND: The accurate identification of venous thromboembolism prophylaxis implementation barriers is an important part of prophylaxis prevention. However, in China, data to help identify these barriers is limited. This study has two objectives: 1) to determine the knowledge, attitudes, and practices (KAPs) of healthcare professionals regarding graduated compression stockings (GCS) since the launch of the National Program for the Prevention and Management of Pulmonary Embolism (PE) and Deep Venous Thrombosis (DVT) in October 2018 and 2) to identify the obstacles and assist the program. METHODS: This was a cross-sectional study of 5070 healthcare professionals in China. We used exploratory factor and reliability analyses to evaluate the researcher-designed questionnaire's reliability and validity. The formal questionnaire, which included demographic data, knowledge, attitudes, and clinical practice patterns, was distributed to healthcare professionals. RESULTS: Of the 5070 respondents, 32.5% had a good knowledge of GCS, 78.5% had a positive attitude towards their use, and 34.0% exhibited normative behavior when applying them. The KAPs of healthcare professionals towards GCS were significantly correlated with one another. Binary logistic regression suggested that the training received by healthcare professionals was an important factor affecting their knowledge regarding GCS usage. CONCLUSIONS: The training provided for the use of GCS in China cannot meet medical staff needs and deserves more attention from policy makers. This represents an obstacle for venous thromboembolism prophylaxis, which restricts the effective implementation of the National Program for Prevention and Management of PE and DVT.

This study had three objectives: (1) to investigate healthcare professionals' knowledge, attitude, and practice toward clinically applying graduated compression stockings, (2) to analyze the influencing factors, and (3) to provide data to support departments that develop health policies. A self-administered web-based survey was completed by 1,444 healthcare professionals, including physicians and nurses from 15tertiary hospitals and four secondary hospitals from 10 provinces in China. Reliability analysis and exploratory factor analysis were used to evaluate the researcher-designed questionnaire's reliability and validity. The formal questionnaire, which included demographic data (eight items), knowledge (ten items), attitudes (four items), and clinical practice patterns (six items), was distributed among healthcare professionals. The relationships and mechanisms among the variables were explored using descriptive statistical analysis, Pearson's correlation coefficients, and multiple linear regression analysis. Of the 1,444 respondents, 31.2% had good knowledge of clinically applying graduated compression stockings, 83.5% had a positive attitude toward clinically applying them, and 30.4% of respondents exhibited normative behavior when applying them. The multiple linear regression analysis indicated that training was an important factor influencing the knowledge, attitude, and practice toward clinically applying graduated compression stockings. The healthcare professionals' attitude toward clinically applying graduated compression stockings was positive, but the related knowledge was poor, and the code of behavior was deficient. Medical institutions should improve training for clinically applying graduated compression stockings among healthcare professionals and standardize the use of graduated compression stockings to facilitate the prevention of hospital-acquired venous thromboembolism.

OBJECTIVE: To investigate the effect of additional semiautomatic intermittent pneumatic compression device (IPCD) in the prevention of deep vein thrombosis (DVT) of lower extremity in these patients undergoing major orthopedic surgery, when compared with the conventional graduated compression stockings alone. METHODS: The data of 112 patients undergoing major orthopedic surgery were retrospectively analyzed. 51 patients who ever received IPCD and graduated compression stockings during major orthopedic surgery were taken as the experimental group, and 61 patients who only received the conventional graduated compression stockings during surgery were taken as the observation group. The Doppler sonography was utilized to detect the presence of DVT and pulmonary embolism pre- and postoperatively. Besides, the mean and peak velocity of blood flow in femoral vein were recorded before and after surgery. And then, the comparisons between the two groups were made, respectively. RESULTS: When compared with the conventional graduated compression stockings alone, the intraoperative application of IPCD and stockings contributed the significant reduction of DVT (3.92%, 2/51 versus 9.84%, 6/61, X2 = 5.632, P = 0.034). In terms of the mean and peak velocity of blood flow in femoral vein, the postoperative difference was higher in the observation group than those in the control group (149.56 ± 26.35 versus 130.15 ± 22.56 mm/s, P < 0.05). With respect to perioperative blood loss, the difference between the two groups was statistically significant (800.5 ± 320.7 versus 950.1 ± 305.9 ml, P = 0.031). CONCLUSIONS: Intraoperative application of IPCD could promote blood circulation of lower limbs, and significantly decrease the incidence of potentially fatal DVT in patients undergoing major orthopedic surgery, when compared with the conventional graduated compression stockings.

BACKGROUND: the patients presenting with severe post-stroke in the acute period of this condition are characterized by the high risk of venous thromboembolic complications (VTEC), with the most dangerous of them being pulmonary embolism that makes an appreciable contribution to the mortality rate of such patients at the hospital stage of their treatment. Among the physical methods for the prevention of VTE, such as wearing graduated compression stockings (GCS), myoelectrostimulation (MES), pneumatic intermittent compression (PIC), only the latter technique has been shown to be efficient when applied for the treatment of surgical patients during the post-stroke period with the level of evidence 2B and the very uncertain parameters of the impact. AIM: The objective of the present study was to evaluate the advantages of the PIC in comparison with that of GCS and MES, substantiate the choice of the former method for the management of the high-risk post-stroke patients, and determine the impact parameters of PIC during the peracute and acute periods of the disease. MATERIAL AND METHODS: We conducted a series of analyses of the results of several controlled randomized studies and relevant reviews of the literature with a view to determining the feasibility and effectiveness of application of one or another approach and clarifying the parameters of the exposure to GCS, MES, and PIC for the prevention of VTEC. RESULTS AND DISCUSSION: The results of these studies gave evidence that the effectiveness of the GCS and MES is insufficient in contrast to that of PIC that was found to decrease the relative risk of deep vein thrombosis (DVT) by 62% compared with placebo and by 47% in comparison with GCS. The low risk of DVT associated with the application of PIC was apparent from the low OR value of 0.45 and the absolute reduction in the risk of DVT by 3.6%. The analysis of the parameters being used made it possible to identify side effects and thereby allowed to formulate the optimal method for the application of PIC for the purpose of prevention of VTEC in the post-stroke patients during the peracute and acute periods of the disease. CONCLUSION: Only PIC of all the currently available methods for the physical prevention of VTEC in the group of high risk post-stroke patients during the peracute and acute periods of this condition can be practiced in the reliable evidence-based manner. The most rational PIC modality consists of exerting the external pressure on the lower extremities within the first 12-24 hours after stroke with the use of the cuffs of the «lower leg¼ type (i.e. at a pressure of 40-50 mm Hg in the wave mode with memorization for the multi-sectional cuffs, daily in the continuous manner throughout the daytime till the patient is downgraded to the group at lower risk of VTEC or actually till the discharge from the hospital.

BACKGROUND: The evidence base upon which current global venous thromboembolism (VTE) prevention recommendations have been made is not optimal. The cost of purchasing and applying graduated compression stockings (GCS) in surgical patients is considerable and has been estimated at £63.1 million per year in England alone. OBJECTIVE: The aim was to determine whether low dose low molecular weight heparin (LMWH) alone is non-inferior to a combination of GCS and low dose LMWH for the prevention of VTE. METHODS: The randomised controlled Graduated compression as an Adjunct to Pharmacoprophylaxis in Surgery (GAPS) Trial (ISRCTN 13911492) will randomise adult elective surgical patients identified as being at moderate and high risk of VTE to receive either the current "standard" combined thromboprophylactic LMWH with GCS mechanical thromboprophylaxis, or thromboprophylactic LMWH pharmacoprophylaxis alone. To show non-inferiority (3.5% non-inferiority margin) for the primary endpoint of all VTE within 90 days, 2236 patients are required. Recruitment will be from seven UK centres. Secondary outcomes include quality of life, compliance with stockings and LMWH, overall mortality, and GCS or LMWH related complications (including bleeding). Recruitment commenced in April 2016 with the seven UK centres coming "on-line" in a staggered fashion. Recruitment will be over a total of 18 months. The GAPS trial is funded by the National Institute for Health Research Health Technology Assessment in the UK (14/140/61).

BACKGROUND: Guidelines from the Japanese Circulation Society recommend prophylaxis with anticoagulation plus intermittent pneumatic compression or graduated compression stockings (GCS) among patients at the highest risk for developing venous thromboembolism (VTE). However, the benefits of concomitant GCS use for patients undergoing total knee arthroplasty (TKA) and receiving anticoagulation remain unknown. In this study, the efficacy of GCS plus anticoagulation compared with anticoagulation alone was evaluated among patients undergoing TKA. METHODS: This study is a post hoc analysis of a previously reported phase 3 trial involving patients undergoing TKA. In the primary study, which permitted the use of GCS for mechanical prophylaxis, patients were randomized to receive edoxaban 30 mg once daily or enoxaparin 20 mg twice daily for 11 to 14 days following TKA. The primary endpoint was the incidence of VTE, a composite of symptomatic deep vein thrombosis (DVT), symptomatic pulmonary embolism (PE), and asymptomatic DVT. Treatment comparisons were performed using the chi-square test, and the 95 % confidence intervals were calculated. RESULTS: Among patients receiving edoxaban, the incidence of VTE was 3.8 and 5.8 % for patients with and without GCS, respectively. For patients receiving enoxaparin, VTE incidence was 8.4 and 20.8 % among those with and without GCS, respectively. Overall, VTE incidence was 6.0 and 13.0 % for anticoagulated patients with and without GCS mechanical prophylaxis, respectively. No deaths or symptomatic PE were reported during this study. CONCLUSIONS: Although the incidence of VTE was >2-fold lower among patients receiving anticoagulation plus GCS compared with those receiving anticoagulation alone, statistical significance was not achieved. Further studies are required to confirm the findings of this preliminary analysis. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01181102.
RESUMO
AIMS AND OBJECTIVES: To compare the comfort levels of patients regarding the use of three different graduated compression stockings and to analyse the efficacies of the graduated compression stockings in relation to patient comfort and compliance in prevention of postoperative deep vein thrombosis. BACKGROUND: Graduated compression stockings are very important with other prophylaxis methods in postoperative deep vein thrombosis prophylaxis. In meta-analyses and systematic review studies, it was reported that knee-length and thigh-length graduated compression stockings had similar efficacies. However, there is no randomised study in literature regarding the patient problems and levels of comfort with the use of graduated compression stockings of different sizes and pressures. DESIGN: A randomised clinical trial design. METHODS: A total of 219 patients were randomised into three groups (n = 73 in each group). Group I was given low-pressure, knee-length graduated compression stockings, group II was given low-pressure, thigh-length graduated compression stockings and group III was given moderate-pressure, knee-length graduated compression stockings. The level of patients comfort regarding the graduated compression stockings and occurrence of deep vein thrombosis were examined. RESULTS: The vast majority of the patients (79·5%) in group III and 52·1% of the patients in group II stated experiencing problems during the use of the graduated compression stockings (p < 0·001). The graduated compression stockings were reported by the patients as being very comfortable in the group I (p < 0·001). No findings of thrombosis were observed in any of the groups. CONCLUSION: The low-pressure, knee-length graduated compression stockings are as effective as the other graduated compression stockings of different pressures and sizes in the postoperative deep vein thrombosis prophylaxis, and the patients have fewer problems while using these graduated compression stockings with a high satisfaction. RELEVANCE TO CLINICAL PRACTICE: The combined use of pharmacological, mechanical and physical methods and patient education is effective in the prevention of postoperative deep vein thrombosis. The use of low-pressure, knee-length graduated compression stockings in clinical practice may be recommended, as the patients have fewer problems while using these graduated compression stockings with a high satisfaction.

BACKGROUND: Calf vein diameters during compression with two different stocking brands are assessed as well as quality of life. PATIENTS AND METHODS: 60 subjects (53 female) with painful legs were randomized to either wearing the Venotrain micro® (VM) or the Venotrain ulcertec® (VU) compression stocking for 2 weeks. All calf - veins were assessed in cross - sectional plane by Duplexsonography native and through the compression stockings. The diameters of 2 gastrocnemius muscle - veins (GV), the short saphenous vein (SSV) and the posterior tibial vein (PTV) were compared intra - individually, with and without compression. RESULTS: Mean diameters (± SD) decreased significantly under compression (p < 0.0001) in the standing position: in the antero-posterior (ap) plane of the GV by 6.5 (± 16.6) % under VU and 8.2 (± 16.5) % under VM, in the SSV 9.7 (± 15.8) % under VU and 5.7 (± 19.2) % under VM. No significant change (p = 0.48) was seen in the PTV. In the prone position the relative ap - diameter changes in the medial GV were significantly smaller for the VM (37.5 ± 51.0 %) compared to the VU compression stocking (52.4 ± 51.8 %) (p = 0.016). The quality of life assessment scores improved significantly for the VU - and the VM - compression stocking. Venous diameters did not correlate with quality of life scores. CONCLUSIONS: Intra - individually tested the calf muscle vein diameters decrease under compression, more pronounced in the prone than in the standing position. In the ankle area the PTV does not decrease in standing subjects. Quality of life assessed increases for both compression stockings.

Chronic venous insufficiency (CVI) represents a risk factor for cardiovascular events. The first-line treatment includes the use of compression stockings and lifestyle changes. Natural products, such as flavonoids, could be used to improve the effects of compression therapy due to their anti-inflammatory and anti-oxidant properties. This study aims to evaluate the effects of a dietary supplement containing baicalin, bromeline and escin in CVI patients. A retrospective cohort study was performed by using the medical records of CVI affected outpatients. Patients treated with the dietary supplement were defined as "users". A modified Venous Clinical Severity Score (VCSS) was calculated, including pain, inflammation, vessels induration and skin pigmentation. All clinical variables were evaluated at baseline (T0), after 30 (T1) and 90(T2) days in "users" and "non-users". Out of 62 patients, 30 (48.4%) were "users". No difference was observed between groups at baseline. A lower VCSS value was recorded in "users" than that observed in "non-users" at T2 (7.0 (4.0-9.0) vs. 9.0 (5.0-10.0); p = 0.025). Vessels' induration and pain significantly reduced in 53.3% and 43.3% of "users" and in 18.8% and 9.4% of "non-users". Only "users" (33.3%) showed a reduction of the inflammatory signs as well as a decrease in malleolar circumference, from 29.0 (26.5-30.0) to 27.5 (26.0-28.5) (p < 000.1). A reduction of C-reactive Protein levels was found in "users" compared to "non-users" at T2 (1.0 (0.9-1.2) vs. 1.3 (1.0-1.5); p = 0.006). These findings suggest that implementation of a dietary supplement could improve the clinical outcomes of CVI patients.
RESUMO
OBJECTIVES: To describe the real-world use of Elastic Venous Compression Devices (EVCDs) during pregnancy and post-partum using data from a representative subset of the French National Health Insurance Claims Database (the Echantillon Généraliste des Bénéficiaires, EGB). STUDY DESIGN: Women aged 15-49 who were pregnant between 1st July 2017 and 15th June 2018 were identified in the EGB using pregnancy-specific acts (certain prenatal examinations or deliveries). Subgroups were defined by age, presence of Venous Thrombo-Embolism (VTE) risk factors, history of VTE, delivery type and time period. EVCD dispensations (format, prescriber, and date) were identified among those for "standard orthotics" using their unique reimbursement tariffs. Dispensation rates were computed for all subgroups, overall and by format and were compared. RESULTS: 15,528 pregnant women were included: 7,252 [46.7 %] deliveries (5,796 vaginal [79.9 %], 482 planned cesarean sections (C-sections) [6.7 %] and 974 unplanned C-Sections [13.4 %]), 2,734 (17.6 %) terminations and 5,542 (35.7 %) unknown outcomes. Overall, 4,919 (31.7 %) women were dispensed at least one EVCD. Ante-partum dispensation occurred in 43.1 % (n = 3,122) of women whose pregnancy led to a delivery. Dispensation rates were 17.3 % (n = 1,005), 46.7 % (n = 225) and 44.1 % (n = 430) after vaginal delivery, planned C-sections or unplanned C-sections, respectively. Overall, dispensation rates significantly increased with age, the presence of VTE risk factors, and a history of VTE (p < 0.01). EVCD dispensation was most frequent (17.0 %) during the 5th month of pregnancy. Among pregnant women who were dispensed at least one EVCD during ante- or post-partum, 69.0 % had one or two units of compression (27.1 % [one unit], 41.9 % [two units]). Stockings (48.6 %, n = 6,038) were dispensed significantly more frequently than socks (36.9 %, n = 4,586) and tights (14.5 %, n = 1,806) (p < 0.01). The main contributors to mechanical VTE prophylaxis were gynecologists (26.3 % of dispensations, n = 2,280), general practitioners (20.2 %, n = 1,749) and midwives (15.1 %, n = 1,314). CONCLUSIONS: Low observed dispensation rates highlight a discrepancy between the French National Authority for Health (Haute Autorité de Santé, HAS), recommending EVCDs use during pregnancy and after delivery, and the real-life use of EVCD. Prescription sensitization combined with targeted information campaigns for pregnant women would be beneficial to contribute to the prevention of VTE, a health problem for pregnant women.

Objective: This study aimed to assess the efficacy of a self-designed progressive resistance exercise training program for preventing the development of lower limb lymphedema. Methods: An open-label randomized controlled trial was conducted in patients who underwent radical surgery for cervical cancer treatment in our department between October 7, 2019, and October 7, 2021. The participants were randomly assigned to one of three groups: progressive resistance exercise training, graduated compression stocking, and control group. Results: A total of 267 patients were enrolled (89 in each group). The incidence of lower limb lymphedema was 9.0% (n = 8) in the progressive resistance exercise training group, 28.1% (n = 25) in the graduated compression stocking group, and 42.7% (n = 38) in the control group. Over the 2-year follow-up period, the risk of lower limb lymphedema was significantly lower in the progressive resistance exercise training group than in the control group, with a hazard ratio (HR) (95% confidence interval [CI]) of 0.156 (0.073-0.335). The study was underpowered to demonstrate a statistically significant reduction in risk in the graduated compression stocking group, with an HR (95% CI) of 0.624 (0.376-1.033). Conclusions: Progressive resistance exercise training is an effective strategy for preventing lower limb lymphedema after pelvic lymphadenectomy for cervical cancer. It imposes no additional economic burden and can be performed conveniently without the need for dedicated exercise facilities. This makes it particularly accessible to patients in developing countries, allowing them to exercise at their convenience. Trial registration: ChiCTR1800014905.
RESUMO
BACKGROUND: Patient compliance is an essential precondition for assessing the effectiveness of graduated compression stockings (GCS). However, patient compliance with use of GCS has not received sufficient attention. Only a few clinical studies have explicitly evaluated patients' adherence to GCS therapy, and the instruments used to measure patient compliance have either not been well adapted to daily use or lacked scientific development techniques. Most instruments have focused on "wear or not wear" or "how long did you wear" questions, which do not consider all the perspectives on patient compliance. In the present study, we used scale development and validation steps to create a self-reported questionnaire to measure patients' compliance with wearing GCS. METHODS: We designed a questionnaire to measure compliance with wearing GCS among patients who had undergone invasive treatment of superficial varicose veins of the lower extremities. The initial questions were determined after a literature review and interviews with experts and patients. Reliability was evaluated using the Delphi method with expert judges, pretesting, Cronbach's alpha, and test-retest reliability. Exploratory and confirmatory factor analyses were used to test the questionnaire's validity. RESULTS: The developed questionnaire had 11 questions with the responses rated from 1 to 4 and included three factors: compliance with correct GCS wearing methods, compliance with GCS wearing cautions, and compliance with seeking advice. The Cronbach alpha for the overall questionnaire was 0.853 (factor 1, 0.934; factor 2, 0.803; factor 3, 0.789), its content validity was good, and the factor structure fitted the data well. CONCLUSIONS: We have presented our initial version of the questionnaire for patients who have undergone invasive treatment of superficial varicose veins of the lower extremities. The questionnaire can be used to evaluate patient compliance with wearing GCS thoroughly and effectively. However, further work is still required to maximize its reliability and validity for its use in daily practice in the future.

OBJECTIVE: Compression therapy with the use of graduated compression stockings (GCSs) is a common treatment strategy for chronic venous disease (CVD). However, there is no uniform and objective standard to assess adherence to the use of GCSs. The aim of this study is to develop and validate a GCS Compliance Scale (GCSAS) to fill gaps in internationally recognized comprehensive scales and provide a useful tool for future research. METHODS: The items included in the GCSAS were based on a review of the literature and open-ended interviews with experts, who screened the initial items using an item-level content validity index. Then, pilot tests were conducted three times with 50 participants. After exclusion of redundant and cross-loading items by exploratory factor analysis, 290 subjects were recruited to evaluate the reliability and validity of the proposed GCSAS. Analyses included internal consistency, test-retest reliability, split-half reliability, construct validity, criterion validity, convergent validity, and discriminant validity. RESULTS: The final GCSAS consisted of 17 items and 5 dimensions. The results of the exploratory factor analysis indicated that the variances of each factor explained were 22.03%, 14.85%, 14.74%, 14.16%, and 13.35%, and all 5 factors explained 79.13% of the variance among the 17 items. The factor loadings of all items were >0.7. Confirmatory factor analysis indicated that the indices were adequate. A significant positive correlation was found between the GCSAS and the Venous Insufficiency Epidemiological and Economic Study - Quality of Life questionnaire scores (r = 0.76, p < 0.001). The Cronbach's alpha coefficient was 0.90, test-retest reliability was 0.81, and split-half reliability was 0.92. CONCLUSIONS: The GCSAS showed good validity and reliability to assess compliance with the use of GCSs among patients with CVD.

Unlike arterial disease, chronic venous disease (CVD) is rarely life-threatening or limb-threatening. However, it can impose substantial morbidity on patients by influencing their lifestyle and quality of life (QoL). The aim of this nonsystematic narrative review is to provide an overview of the most recent information on the management of CVD and specifically, iliofemoral venous stenting in the context of personalized considerations for specific patient populations. The philosophy of treating CVD and phases of endovenous iliac stenting are also described in this review. Additionally, the use of intravascular ultrasound is described as the preferred operative diagnostic procedural tool for iliofemoral venous stent placement.
RESUMO
OBJECTIVES: This study aims to examine uptake and dissemination of a National Institute for Health Research (NIHR) Health Technology Assessment (HTA)-funded trial - Graduated compression as an Adjunct to Pharmaco-thromboprophylaxis in Surgery (GAPS) (project number: 14/140/61) amongst health professionals in the UK. This study aims to evaluate the impact of the trial on venous thromboembolism (VTE) prevention policies 7 months after publication. METHOD: A 12-question online survey emailed to 2750 individuals via several vascular societies, 34 VTE Exemplar Centre leads and 1 charity over a 3-month period. RESULTS: In total, 250 responses were received; a 9.1% response rate. Over half of all respondents (52.4%) had read the GAPS trial results prior to completing the survey. Precisely, 77.1% said their hospital had not yet made changes or did not intend to make changes to local hospital VTE policy based on the GAPS trial. CONCLUSIONS: Findings must be interpreted in the context of the low response rate. Further in-depth interviews would aid understanding of barriers to implementing change.

This paper focuses on the comfort properties of graduated and preventive compression stockings for people who work long hours in standing postures and for athletes for proper blood circulation. The present study was conducted in order to investigate the effects of the yarn insertion density and inlaid stitches on the performance of the compression stockings. The effects of these parameters on the thermo-physiological comfort properties were tested with standard and developed methods of testing. All compression stockings were maintained with class 1 pressure as per German standards. The structural parameters of the knitted fabric structures were investigated. The stretching and recovery properties were also investigated to determine the performance properties. The theoretical pressure was predicated using the Laplace's law by testing the stockings' tensile properties. The compression interface pressures of all stockings were also investigated using a medical stocking tester (MST) from Salzmann AG, St. Gallen, Switzerland. Correlation between the theoretical pressures and pressures measured using the MST system were also assessed. The current research used a multi-response optimization technique, i.e., principal component analysis (PCA), to identify the best structure based on the optimalization of the above-mentioned properties. The results also revealed that samples with higher insertion density levels exhibit better comfort properties. The results showed that sample R1 was the best sample, followed by R2 and P. In addition, all developed stocking samples exhibited better comfort properties than the control sample from the market.
