Chronic venous insufficiency and varicose veins of the lower extremities

Preliminary Study of Noncontrast-Enhanced Magnetic Resonance Imaging for the Diagnosis and Management Iliac Venous Compression Syndrome

BACKGROUND

The purpose of this study was to determine the technical feasibility and safety of noncontrast-enhanced magnetic resonance imaging (MRI) in the diagnosis and management of iliac vein compression syndrome (IVCS) compared with 3-dimensional rotational venography (3D-RV).

METHODS

The general epidemiological data (including age and gender), clinical manifestations (including major symptom; affected extremity; clinical, etiology, anatomy, and pathophysiology classification; comorbidity; stenosis rate; and Valletta score), and intraoperative findings (collateral vessels present or absent) of 39 IVCS patients who were assessed by both noncontrast-enhanced MRI and 3D-RV between January 2018 and January 2022 were obtained and analyzed.

RESULTS

The iliac vein stenosis rate determined by noncontrast-enhanced MRI and 3D-RV was 79.09 ± 1.57% vs. 80.06 ± 1.62%, respectively (P = 0.13). With the aggravation of Villalta score, the detection rate of both noncontrast-enhanced MRI and 3D-RV for collateral vessels present increased significantly. Compared with 3D-RV, noncontrast-enhanced MRI is more sensitive for the detection of collateral vessels present in early chronic venous disease (P = 0.03). Of these patients, 20 patients were treated with MR images fusion navigation, and 19 patients were treated with 3D venography images fusion navigation during endovascular management. Significant differences were observed between the noncontrast-enhanced MRI and 3D-RV groups concerning X-ray dose (1,695 ± 36.01 mGy vs. 2,820 ± 23.06 mGy; P < 0.001) and contrast agent dosage (49.25 ± 1.02 mL vs. 83.79 ± 2.75 mL; P < 0.001).

CONCLUSION

Noncontrast-enhanced MRI is a quick, efficient, and accurate noninvasive technique for the evaluation and diagnosis of IVCS. In addition to providing the required anatomic information to make the diagnosis of IVCS, it also provides all this intraoperative "roadmap" for possible endovascular management of IVCS.

Rétrograde venous perfusion (RVP) for intraçtable venous leg ulcers: a retrospective analysis

BACKGROUND

Retrograde venous perfusion (RVP) is a minimally invasive procedure in which the limb circulation is isolated by the application of a proximal limb tourniquet, followed by the administration of specific medications through a distal limb vein. This allows these drugs to pass in the reverse direction to reach the ulcerated area of the affected limb. The aim of this study was to evaluate the safety, feasibility, and efficacy of RVP, for the management of long-standing intractable chronic venous leg ulcers (CVLUs).

METHODS

A 4-year retrospective study took place from January 2021 to January 2025. All patients who underwent the RVP technique were included in the study. These patients had chronic, intractable, long-standing, nonhealing, venous leg ulcers. They were classified into two groups. Group I included those who underwent RVP (treated group). However, group II was treated with standard compression therapy (control group). A paired-samples t test was performed to compare the studied groups. Kaplan-Meier survival analysis was performed for patients who were free from ulcer recurrence or nonhealing after the RVP technique.

RESULTS

During the 4-year study period, 384 patients were retrospectively analyzed. A total of 75% (n = 288) of the participants were females, and 25% were males (n = 96). The median age was 37.26 ± 4.2 years. Ulcers ranged between 30cm2 and near circumferential. The median ulcer duration was 18 ± 14.4 months. The mean number of RVP sessions was 26.78 ± 7.6, whereas the mean session time was 213 ± 49 min. A reduction in ulcer size/complete healing was achieved in 96.9% of the patients in group I vs. 68.8% of those in group II.

CONCLUSIONS

Compared with the standard compression technique, RVP therapy may be considered an effective and feasible technique for treating intractable venous leg ulcers. It offers shorter periods of therapy with a high success rate in reducing ulcer size/complete wound healing within a short period of time. This therapeutic option may provide essential evidence to reduce the negative social and economic impact on affected populations.

Superior arterial signal suppression in lower extremity magnetic resonance venography: A comparative study of tracking and fixed saturation pulses

PURPOSE

This study aimed to compare the suppression of arterial signal intensity between tracking and fixed saturation pulses in lower extremity magnetic resonance venography (MRV).

METHODS

Forty patients with varicose veins who underwent 2D true fast imaging with steady-state free precession using tracking and fixed saturation pulses on MRV were included. A fixed saturation pulse was applied from April 2020 to May 2021, and a tracking saturation pulse was applied from June 2021 to July 2022. The arterial, venous, and muscle signal intensities obtained at the femoral and popliteal levels were used to calculate the contrast ratios between veins and arteries (CRVA) and veins and muscles (CRVM). Two experienced radiologists graded the images based on vein-artery contrast, suppression of arterial signal intensity, and visualization of lower leg perforators using a 9-point scale.

RESULTS

Tracking saturation pulse images yielded significantly superior CRVA and CRVM compared with fixed saturation pulse images at both the femoral and popliteal levels. For the same saturation pulse type, the CRVA was higher at the femoral level than at the popliteal level, while the CRVM was comparable between the two levels. MRV with a tracking saturation pulse showed significantly superior vein-artery contrast, arterial signal suppression, and lower leg perforator visualization. Most scores for vein-artery contrast and arterial signal suppression with the tracking saturation pulse were positive (3.5-5), whereas few scores with the fixed saturation pulse were positive.

CONCLUSION

Tracking saturation pulse was more effective in suppressing arterial signal intensity in lower extremity MRV.

Therapeutic applications of natural products in the management of venous diseases: a comprehensive review

The occurrence of venous diseases among adults is approximately 77% in females and 57% in males. These conditions are prevalent, progressive disorders that significantly affect individuals socially, physically, and psychologically, often resulting in various venous abnormalities that hinder effective blood circulation in the lower limbs. This review provides a comprehensive overview of venous diseases, focusing on their pathophysiology, symptoms, causes, risk factors, diagnosis, and complications. The symptoms associated with venous diseases are diverse and can include pain, heaviness, swelling, ulcers, and skin changes. Risk factors such as age, obesity, hormonal influences, and genetic predispositions are discussed in relation to their contribution to disease progression. The therapeutic modalities for managing venous diseases are explored, with a particular emphasis on natural products in alleviating symptoms and improving vascular health. Natural compounds, i.e., flavonoids, play a vital role in the circulatory system, supporting blood vessels and promoting healthy blood flow, in addition to their vasoprotective, antioxidant, anti-inflammatory, and anti-platelet properties. Overall, the ongoing research efforts on the efficacy of natural products will significantly enhance the management of several venous diseases in the coming years.

Efficacy of complex decongestive therapy on venous flow, internal saphenous diameter, edema, fat mass of the limbs and quality of life in patients with chronic venous insufficiency: A randomized clinical trial

OBJECTIVE

Demonstrate the effectiveness of complex decongestive therapy (CDT) in patients with chronic venous insufficiency (CVI).

METHODS

A single-blind randomized controlled trial was conducted, where the participants were patients with CVI (n = 21/42) were assigned randomly to an experimental group (n = 11/22) or a control group (n = 9/18). A treatment of CDT (manual lymphatic drainage, intermittent pneumatic presotherapy, bilayer bandage) was applied to the experimental group for 4 weeks 2 days per week and no treatment was applied to the control group. The patients were evaluated at baseline (t0), 1 week after finishing the intervention (t1), and 6 weeks after the intervention (t2). The effectiveness of the treatment on symptoms and quality of life (QoL) (heaviness, pain and Chronic Venous Insufficiency Quality of Life [CIVIQ-20] questionary), edema, venous flow, and impedanciometry measurements was evaluated.

RESULTS

An improvement in the patient's QoL was observed: there was a decrease in symptoms such as heaviness and pain, an increase in the average velocity of the left femoral vein and left internal saphenous vein (ISV), a decrease in the ISV diameter in both extremities and a decrease in body mass index and fat mass in both extremities. These results were maintained when following up at 6 weeks, except for the improvement of QoL.

CONCLUSIONS

CDT treatment improves the CIVIQ-20 and Venous Clinical Severity Scores. It also improves symptoms (pain and heaviness), venous flow velocity (superficial veins and deep veins [common femoral vein, femoral vein, popliteal vein]) and decreases body mass index, fat mass, and ISV diameter.

Physical activity levels in patients with chronic venous insufficiency

BACKGROUND

Increasing the levels of physical activity (PA) is widely recommended for people with chronic venous insufficiency (CVI). However, studies investigating the patterns of PA and adherence to PA guidelines using objective measures are lacking.

OBJECTIVE

The primary aim was to examine the patterns of PA and adherence to PA guidelines among patients with CVI. A secondary aim was to identify whether adherence to PA recommendations differed according to patients' sociodemographic and clinical characteristics.

METHODS

This cross-sectional study included 96 patients with CVI with Clinical-Etiology-Anatomy-Pathology (CEAP) C3 to C6 (69.1% women 59 ± 11 years; 51.5% C5-C6 on CEAP classification). Objective time spent in PA was measured by a triaxial accelerometer. To examine adherence to PA guidelines, patients were grouped as meeting (or) the recommendations if they had at least 150 min/week of moderate to vigorous PA. Sociodemographic and clinic characteristics were obtained by self-report. Binary logistic regression was employed to examine whether sociodemographic and clinical characteristics were associated with adherence to PA guidelines. T-tests were employed to compare PA levels at different intensities according to patients' age.

RESULTS

Patients spent an average of 311.4 ± 91.5 min/week, 42.1 ± 28.0 min/week, and 19.8 ± 17.8 min/week in low-light PA, high-light PA, and moderate-to-vigorous PA, respectively. The proportion of patients meeting PA recommendations was 36.2%, and older patients had lower odds (OR = 0.94; 95%CI: 0.89 to 0.99). Additional analysis reinforced that by showing lower time in high-light PA (51.2 ± 30.0 min/day vs. 31.9 ± 21.8 min/day; p = .001) and moderate-to-vigorous PA (24.3 ± 15.8 min/day vs. 14.8 ± 18.8 min/day; p = .012) among older patients than their peers younger.

CONCLUSION

Our findings showed that 36,2% of CVI patients met PA recommendations, with lower odds found among older patients. Public health interventions to enhance PA engagement among CVI patients should prioritize those who are older.

Results from a comparative study to evaluate the treatment effectiveness of a nonpneumatic compression device vs an advanced pneumatic compression device for lower extremity lymphedema swelling (TEAYS study)

OBJECTIVE

Advanced pneumatic compression devices (APCDs) have been shown to be effective in treatment of lower extremity lymphedema in the home setting. However, adherence to self-care has been poor, and APCDs require patients to remain immobile during treatment. We evaluated the safety and efficacy of a novel nonpneumatic compression device (NPCD) for treating lower extremity lymphedema vs an APCD.

METHODS

A randomized, crossover head-to-head study was performed at nine sites in 2023. Patients were randomized to either the NPCD or a commercially available APCD. Patients used the randomly assigned initial device for 90 days with a 4-week washout period before a comparable 90-day use of the second device.

RESULTS

A total of 71 patients (108 affected limbs) with lower extremity lymphedema were analyzed. Compared with the APCD, the NPCD was associated with a greater mean decrease in limb edema volume (a mean limb volume decrease of 369.9 ± 68.19 mL [P < .05] vs 83.1 ± 67.99 mL [P < .05]). Significant improvement in Quality of Life was achieved for NPCD and but not for APCD treatment (score improvement of 1.01 ± 0.23 [P < .05] for NPCD vs 0.17 ± 0.18 [P > .05] for APCD). Patients reported greater adherence (81% vs 56%; P < .001) and satisfaction with the NPCD (78% vs 22%) compared with APCD. No device-related adverse events were reported.

CONCLUSIONS

The novel NPCD is an effective treatment for decreasing limb volume in patients with lower extremity lymphedema. The NPCD was more effective than an APCD and resulted in superior limb volume decrease, greater improved quality of life, adherence, mobility, and patient satisfaction.

Omics Data Integration Uncovers mRNA-miRNA Interaction Regions in Genes Associated with Chronic Venous Insufficiency

Background/Objectives: Chronic venous insufficiency (CVI), a chronic vascular dysfunction, is a common health problem that causes serious complications such as painful varicose veins and even skin ulcers. Identifying the underlying genetic and epigenetic factors is important for improving the quality of life of individuals with CVI. In the literature, many genes, variants, and miRNAs associated with CVI have been identified through genomic and transcriptomic studies. Despite molecular pathogenesis studies, how the genes associated with CVI are regulated by miRNAs and the effect of variants in binding regions on expression levels are still not fully understood. In this study, previously identified genes, variants, and miRNAs associated with CVI, common variants in the mRNA-miRNA binding regions, were investigated using in silico analyses. Methods: For this purpose, miRNA research tools, MBS (miRNA binding site) database, genome browsers, and the eQTL Calculator in the GTEx portal were used. Results: We identified SNVs associated with CVI that may play a direct role in the miRNA-mediated regulation of the ZNF664, COL1A2, HFE, MDN, MTHFR, SRPX, TDRD5, TSPYL4, VEGFA, and APOE genes. In addition, when the common SNVs in the mRNA binding region of 75 unique CVI related-miRNAs in five candidate genes associated with CVI were examined, seven miRNAs associated with the expression profiles of ABCA1, PIEZO1, and CASZ1 genes were identified. Conclusions: In conclusion, the relationship between genetic markers identified in the literature that play a role in the pathogenesis of the CVI and the expression profiles was evaluated for the first time in the mRNA-miRNA interaction axis.

A novel non-pneumatic compression device results in reduced foot and ankle swelling in patients with venous and lymphatic edema

OBJECTIVES

Non-pneumatic compression devices (NPCDs) rely on shape-memory alloy technology that allows patients to ambulate and remain active during lymphedema treatment. This study examines the effect of the NPCD on foot and ankle swelling.

METHODS

This was a prospective, non-randomized study of patients with phlebolymphedema (venous insufficiency-related lymphedema) treated with a novel NPCD for 4 weeks. Ankle and foot circumference (cm), and volume measurements (ml water displacement using immersion) of the foot and ankle were obtained at enrollment, 2-weeks, and 4-weeks, and ambulation was tracked with a wearable exercise monitoring device.

RESULTS

This study included 13 patients (21 limbs). A significant reduction in circumference (ankle (-0.84 ± 0.22 cm, p < .01) and metatarsal bed (-0.55 ± 0.95, p < .01)) and volume (foot/ankle (-52 ± 22 mL, p = .032)) was observed. Patients reported a mean of 8100 steps per day (±6100).

CONCLUSIONS

NPCD results in significant reduction in edema in the foot and ankle despite garments lacking a foot piece. Patients remained mobile while adhering to therapy.

Photoplethysmography-based assessment of varicose vein-related risk factors, exercise health beliefs, and venous refill time in healthcare professionals working in operating rooms and outpatient clinics

BACGROUND

Impaired venous return is observed in healthcare professionals who spend long periods standing and sitting. This descriptive cross-sectional study was conducted to evaluate varicose vein-related risk factors, exercise health beliefs, and venous refill time in healthcare professionals working in operating rooms and outpatient clinics by photoplethysmography.

METHOD

The study sample consisted of 100 healthcare professionals without a diagnosis of peripheral venous insufficiency. Data were collected using a descriptive characteristics form, the Health Belief Model Scale for Exercise, the Short-Form McGill Pain Questionnaire, and photoplethysmography.

RESULT

This study found that OR nurses had shorter venous refill times and experienced more pain due to prolonged standing, despite their high health beliefs about exercise.

CONCLUSION

Healthcare professionals working in operating rooms should be screened for venous insufficiency and trained regarding the practices to prevent venous insufficiency, such as lying down, elevating legs, and using elastic stockings.

Innovative Approaches and Future Directions in the Management and Understanding of Varicose Veins: A Systematic Review

Varicose veins, a prevalent condition that primarily affects the lower limbs, present significant hurdles in diagnosis and treatment due to their diverse causes. This study dives into the complex hormonal, environmental, and molecular elements that influence varicose vein genesis, emphasizing the need for precise diagnostic methods and changing therapy approaches to improve patient outcomes. It investigates the epidemiology and demographic distribution of varicose veins, delves into their pathophysiology, and assesses diagnostic methods such as duplex ultrasonography and the CEAP classification system. In addition, the study discusses novel therapies such as sclerotherapy and endovenous thermal ablation, as well as the effectiveness of existing diagnostic methods in detecting chronic venous illnesses. By investigating venous wall remodeling and inflammatory pathways, it gives a thorough knowledge of varicose vein formation. The study calls for future research that focuses on patient-centered methods, bioengineering advances, digital health applications, and genetic and molecular studies to improve the accuracy and effectiveness of vascular therapy. As a result, a multidisciplinary literature analysis was done, drawing on insights from vascular medicine, epidemiology, genetics, and pharmacology, to consolidate existing knowledge and identify possibilities to enhance varicose vein diagnosis, treatment, and patient care outcomes.

Challenging conventions: Reconsidering the indication for endovenous ablation in CEAP 2 patients

INTRODUCTION

Endovenous ablation may not always be necessary for every patient with chronic venous insufficiency who has an indication for endovenous ablation. This study investigates whether compression stockings and Daflon® can be as effective for some patients with CEAP two in chronic venous insufficiency.

METHODS

In this study, 137 patients who had endovenous ablation indication received plethysmographical hemodynamic tests and were divided into two groups. Group 1 had normal venous hemodynamics and received compression stockings and Daflon®. Group 2 had abnormal function and received laser ablation. All patients were reevaluated after 6 months.

RESULTS

The study showed that there was no statistically significant difference between Groups 1 and 2 in the 6th month measurements after the treatments.

CONCLUSION

As a result, we do not find it appropriate and do not recommend that every patient with complaints of chronic venous insufficiency and an indication for endovenous ablation undergo ablation without evaluating lower extremity venous hemodynamics.

Safety and efficacy of endovenous microwave ablation for treatment of varicose veins of the lower limbs in China: A prospective registered clinical trial

OBJECTIVE

This study aimed to investigate the safety and efficacy of a new Chinese device using microwave ablation for treating symptomatic great saphenous vein (GSV) varicose veins (VVs).

METHODS

This prospective, single-arm, single-center, cohort study investigated the safety and efficacy of endovenous microwave ablation for the treatment of symptomatic VVs. A total of 50 patients with lower limb varicose veins were enrolled from the Hospital of Chengdu University of Traditional Chinese Medicine. The clinical outcomes and complications were assessed at 1, 6, and 12 months after the procedure. The primary outcome was the occlusion rate of GSV immediately and at 1, 6, and 12 months after the treatment. The secondary outcomes included the venous clinical severity score (VCSS), the chronic venous insufficiency questionnaire 14 items (CIVIQ-14) score, the Aberdeen varicose vein questionnaire (AVVQ) score, and the pain visual analog scale (VAS) score. This study protocol was registered at ClinicalTrials.gov (ID: NCT04645771).

RESULTS

In total, 50 limbs from 50 patients (26 female; mean age: 53.45 ± 9.78 years) were treated. A technical success rate of 100% was achieved and no serious adverse events were recorded. During the follow-up period, the occlusion rate of the major/minor saphenous vein trunk remained 100% at 1, 6, and 12 months after surgery except one patient fell off. The median 24-h VAS value was 2 (2,3). The VCSS score, CIVIQ-14 score, and AVVQ score (p < .05) at 1, 6, and 12 months improved significantly compared with the value preoperative (p < .05).

CONCLUSION

EMA was safe and effective for treating varicose veins in the lower limbs, with a high rate of venous trunk occlusion and few complications, thus improving patients' postoperative quality of life.

Improvements in edema and microcirculation in chronic venous insufficiency with Pycnogenol® or elastic compression

BACKGROUND

Chronic venous insufficiency (CVI) is the consequence of venous valve reflux and/or venous flow obstruction and resulting venous hypertension in the lower extremities. The aim of this prospective supplement registry study was to evaluate the efficacy of compression stockings or Pycnogenol® in controlling symptoms and edema in CVI and their efficacy on microcirculatory parameters.

METHODS

Two comparable groups of 30 subjects with CVI were observed for 4 months.

RESULTS

Elastic compression was less tolerated than Pycnogenol® with 12 subjects being unable to follow the compression routine. No side effects due to supplementation were observed; tolerability of the supplementation was optimal. Ambulatory venous pressure (AVP) and refilling time (RT) at inclusion indicated a significant increase in venous pressure and reflux (refilling time <16 seconds). AVP and RT did not change after 4 months. Microcirculatory and clinical measurements were comparable at inclusion between the 2 groups. After 4 months, skin resting flux (RF) and skin PO2-PCO2 were significantly improved with Pycnogenol® compared to compression (P<0.05). The significant increase in skin PO2 and the decrease in PCO2 after Pycnogenol® intake were ascribed to the decrease in the abnormally high skin resting flux, a sign of better perfusion and skin nutritional supply. Pycnogenol® reduced leg volume, on average by 18.3% in the evening compared to 4.4% of reduction with compression (P<0.05) showing an important effect on edema. The venous Clinical Severity Score (VCSS) and the composite symptom score (CSS) decreased significantly in the Pycnogenol® group compared to compression, indicating a better improvement in microcirculatory perfusion and nutritional supply produced by the supplementation of Pycnogenol® in comparison with compression. Pycnogenol® significantly improved microcirculation and clinical symptoms in comparison with compression. The decrease in local oxidative stress (OS) at the distal perimalleolar region with Pycnogenol® was significant in comparison with compression (P<0.05). A lower local OS is an important metabolic indication of a better capillary perfusion with better nutritional exchanges. At the end of the registry study, four small ulcerations and skin breaks in four limbs (between 3 and 5 mm of maximum diameters) were observed in the compression group. No ulcerations or skin breaks were observed in the Pycnogenol® group.

CONCLUSIONS

Pycnogenol® relieved edema, improved microcirculation in CVI patients and reduced stationary, interstitial fluid in comparison with compression. Most symptoms of CVI are associated with interstitial water retention; the presence of extra fluid in limb tissues alters perfusion and nutrient supply. Pycnogenol® supplementation reduced water and fluid accumulation in CVI limbs and improved microcirculation and local oxidative stress thus showing important anti-edema effects.

Superficial Venous Disease-An Updated Review

BACKGROUND

This review article provides an updated review of a relatively common pathology with various manifestations. Superficial venous diseases (SVDs) are a broad spectrum of venous vascular disease that predominantly affects the body's lower extremities. The most serious manifestation of this disease includes varicose veins, chronic venous insufficiency, stasis dermatitis, venous ulcers, superficial venous thrombosis, reticular veins, and spider telangiectasias.

METHODS

The anatomy, pathophysiology, and risk factors of SVD were discussed during this review. The risk factors for developing SVD were related to race, age, sex, lifestyle, and certain genetic conditions as well as comorbid deep vein thrombosis. Various classification systems were listed, focusing on the most common one-the revised Clinical-Etiology-Anatomy-Pathophysiology classification. The clinical features including history and physical examination findings elicited in SVD were outlined.

RESULTS

Imaging modalities utilized in SVD were highlighted. Duplex ultrasound is the first line in evaluating SVD but magnetic resonance imaging and computed tomography venography, plethysmography, and conventional venography are feasible options in the event of an ambiguous venous duplex ultrasound study. Treatment options highlighted in this review ranged from conservative treatment with compression stockings, which could be primary or adjunctive to pharmacologic topical and systemic agents such as azelaic acid, diuretics, plant extracts, medical foods, nonsteroidal anti-inflammatory drugs, anticoagulants and skin substitutes for different stages of SVD. Interventional treatment modalities include thermal ablative techniques like radiofrequency ablationss, endovenous laser ablation, endovenous steam ablation, and endovenous microwave ablation as well as nonthermal strategies such as the Varithena (polidocanol microfoam) sclerotherapy, VenaSeal (cyanoacrylate) ablation, and Endovenous mechanochemical ablation. Surgical treatments are also available and include debridement, vein ligation, stripping, and skin grafting.

CONCLUSIONS

SVDs are prevalent and have varied manifestations predominantly in the lower extremities. Several studies highlight the growing clinical and financial burden of these diseases. This review provides an update on the pathophysiology, classification, clinical features, and imaging findings as well as the conservative, pharmacological, and interventional treatment options indicated for different SVD pathologies. It aims to expedite the timely deployment of therapies geared toward reducing the significant morbidity associated with SVD especially varicose veins, venous ulcers, and venous insufficiency, to improve the quality of life of these patients and prevent complications.

Use of low-level laser therapy as an adjuvant therapy for phlebostatic lesions

Low-intensity laser therapy (LILT) is commonly used as an adjuvant therapy for treating injuries. This integrative literature review was carried out in the MEDLINE, LILACS, CUMED, BDENF, SPORTDiscus, Dentistry & Oral Sciences Source, Academic Source and CINAHL databases. Among the inclusion criteria were: range from 2011 to 2021, in English, Portuguese and Spanish and any study, with the exception of preprints and books. The question was answered: "What is the effectiveness described in the literature of using low-intensity laser therapy (LILT) in the treatment of venous lesions?" The wavelength used in studies varied from 635 nm of red ray to 780 nm of infrared ray, generating healing improvement at any length. LBI presented itself as a low-cost and easy-to-apply adjuvant option, alleviating pain complaints and improving healing in patients with vasculogenic lesions.

Factors associated with clinical severity in chronic venous disease: The role of functional parameters

INTRODUCTION

Chronic venous disease (CVD) is a highly prevalent disease that presents a wide spectrum of clinical expressions due to abnormalities in the venous system. Patients often have major functional changes that can limit daily activities. However, the functional factors associated with the severity of the disease remain poorly understood.

OBJECTIVE

To identify the functional factors associated with CVD severity.

METHODS

Seventy-five patients with CVD (92.0% females, 49.6 ± 13.3 years) were evaluated through clinical examination, lower limb perimetry, ankle range of motion (AROM), and lower limb muscle strength by the Heel Rise test, and Sit-to-stand test. Patients were stratified according to the disease severity as mild (telangiectasia, varicose veins, or edema in the lower limbs) or severe CVD (trophic changes or venous ulcer).

RESULTS

Patients with severe CVD (n = 13) were older (p = 0.002), predominantly male (p = 0.007), with reduced AROM in dorsiflexion (p = 0.028) and inversion (p = 0.009), reduced lower limb strength by the Heel Rise test (p = 0.040), and greater circumference of the calf (p = 0.020), ankle (p = 0.003), and plantar arch (p = 0.041) when compared to mild CVD (n = 62). Advanced age, male sex, lower ankle range of motion in dorsiflexion, and greater ankle and plantar arch circumferences were associated with CVD severity. However, the ankle circumference (OR 1.258, 95% CI: 1.008-1.570; p = 0.042), together with advanced age and male sex, was the only functional variable that remained independently associated with CVD severity.

CONCLUSION

The increased ankle circumference was a determinant of the CVD severity and may assist in risk stratification and guide treatment goals in this population.

Preliminary application of three-dimensional venography and fusion navigation technique in May-Thurner syndrome

OBJECTIVE

The purpose of this study was to report a technique for intraprocedural guidance of endovascular iliac vein stenting procedures using three-dimensional (3D) venography images as an overlay on live biplanar fluoroscopy.

METHODS

Using 3D venography and a fusion navigation technique, percutaneous transluminal angioplasty and stent placement were performed to evaluate the feasibility of using 3D venography images and the fusion navigation technique to treat MTS compared with traditional digital subtraction angiography. The general epidemiologic data (ie, age, gender), clinical manifestations (ie, major symptoms, affected extremity, CEAP [clinical, etiology, anatomy, pathophysiology] classification, comorbidity, stenosis rate), intraoperative findings (ie, stent type, stent count, stent to inferior vena cava distance, procedure time, radiation dose, contrast agent dosage), and postoperative recovery were obtained and analyzed.

RESULTS

A total of 30 consecutive patients with symptomatic MTS from our institution were enrolled in the present study. Of the 30 patients, 12 (group A) were treated using 3D venography images and fusion navigation and 18 (group B) were treated with two-dimensional venography images during endovascular management. Significant differences were observed between the two groups with respect to the procedure time (64.42 ± 4.35 minutes vs 76.61 ± 3.47 minutes; P = .04), radiation dose (2152 ± 124.7 mGy vs 2561 ± 105.6 mGy; P = .02), and contrast agent dosage (71.42 ± 4.87 mL vs 86.17 ± 4.14 mL; P = .03).

CONCLUSIONS

3D venography and its fusion navigation technique can improve prediction of the coverage area of the stent. Its use can also shorten the procedure time and reduce the contrast agent dose and radiation exposure, making it a valuable tool for both the diagnosis and the treatment of symptomatic MTS.

Stasis Dermatitis: The Burden of Disease, Diagnosis, and Treatment

Stasis dermatitis (SD), an inflammatory dermatosis occurring on the lower extremities, is a cutaneous manifestation of chronic venous insufficiency (CVI). SD is associated with a significant burden of disease. Symptoms such as pain, swelling, and itching can be debilitating for patients, leading to poor sleep, loss of mobility, and the inability to perform daily activities, and can interfere with work and leisure activities. Moreover, SD is a progressive disease with serious secondary complications such as ulcerations, which increase the patients' morbidity, reduce their quality of life, and increase health care burden. Challenges in diagnosing patients may have both short- and long-term sequalae for the patients due to unnecessary treatment and management. In addition, misdiagnosis may result in hospitalizations, placing additional burden on health care professionals in terms of time and financial burden on the health care system. Compression therapy and leg elevation represent the mainstay of treatment for CVI; however, it is also difficult to self-manage, which places a substantial burden on patients and caregivers. Moreover, compression therapy may cause discomfort and exacerbate itching. Subsequent nonadherence may result in disease progression that places additional burden on the physicians who manage these patients and the health care system in terms of resources required and costs incurred. A large proportion of patients with SD develop allergic contact dermatitis because of innate immune signals and altered skin barrier predisposing to sensitization to topical prescriptions, over-the-counter medications, and compression devices used to treat SD. Other than topical corticosteroids, there are no approved pharmacological options to treat inflammation in SD.

32-year-old Traumatic Arteriovenous Fistula Presenting With Leg Ulcer and High-output Heart Failure

Traumatic arteriovenous fistula (AVF) is not a common disorder, and dermatological signs and heart failure caused by AVF are rarely reported. We present the case of a 55-year-old woman who was referred for congestive heart failure symptoms. Echocardiography revealed preserved left ventricular ejection fraction. Due to edema of the right leg with a long-standing leg ulcer and palpable femoral thrill, duplex ultrasonography was performed. It showed an AVF between the right superficial femoral artery (SFA) and the right femoral vein (FV). The patient recalled a 32-year-old gunshot injury that was not medically treated. After the diagnosis of AVF she was referred to a surgeon for an AVF ligation, with subsequent resolution of her symptoms. The differential diagnosis of leg ulcer with leg edema should include the possibility of AVF as a cause.

Identifying potential drug targets for varicose veins through integration of GWAS and eQTL summary data

Background

Varicose veins (VV) are a common chronic venous disease that is influenced by multiple factors. It affects the quality of life of patients and imposes a huge economic burden on the healthcare system. This study aimed to use integrated analysis methods, including Mendelian randomization analysis, to identify potential pathogenic genes and drug targets for VV treatment.

Methods

This study conducted Summary-data-based Mendelian Randomization (SMR) analysis and colocalization analysis on data collected from genome-wide association studies and cis-expression quantitative trait loci databases. Only genes with PP.H4 > 0.7 in colocalization were chosen from the significant SMR results. After the above analysis, we screened 12 genes and performed Mendelian Randomization (MR) analysis on them. After sensitivity analysis, we identified four genes with potential causal relationships with VV. Finally, we used transcriptome-wide association studies and The Drug-Gene Interaction Database data to identify and screen the remaining genes and identified four drug targets for the treatment of VV.

Results

We identified four genes significantly associated with VV, namely, KRTAP5-AS1 [Odds ratio (OR) = 1.08, 95% Confidence interval (CI): 1.05-1.11, p = 1.42e-10] and PLEKHA5 (OR = 1.13, 95% CI: 1.06-1.20, p = 6.90e-5), CBWD1 (OR = 1.05, 95% CI: 1.01-1.11, p = 1.42e-2) and CRIM1 (OR = 0.87, 95% CI: 0.81-0.95, p = 3.67e-3). Increased expression of three genes, namely, KRTAP5-AS1, PLEKHA5, and CBWD1, was associated with increased risk of the disease, and increased expression of CRIM1 was associated with decreased risk of the disease. These four genes could be targeted for VV therapy.

Conclusion

We identified four potential causal proteins for varicose veins with MR. A comprehensive analysis indicated that KRTAP5-AS1, PLEKHA5, CBWD1, and CRIM1 might be potential drug targets for varicose veins.

Comparison of the therapeutic efficacy of magneto-LED therapy and magnetostimulation applied as the adjuvant treatment of venous leg ulcers - preliminary study

PURPOSE

Venous leg ulcers are chronic wounds that are difficult to cure. The aim of the study was to compare the therapeutic efficacy of two methods of physical medicine - magneto-LED therapy and magnetostimulation, applied as adjuvant treatment in the treatment of venous leg ulcers.

METHODS

The study included 81 patients, 37 male (45.6%) and 44 female (54.3%) ones, age range between 45 and 90 years, with venous leg ulcers. The patients were assigned to two study groups: magneto-LED therapy (group 1) or magnetostimulation (group 2). In both groups, a total of 40 daily procedures were performed. Wound healing was evaluated using computerized planimetry and the pain intensity on numeric rating scale.

RESULTS

After treatment, the decrease in healing rate in group 1 was statistically significantly higher in comparison to group 2 (p < 0.001), while a statistically significant reduction in the surface area of ulcers was obtained, amounting on the average from 6.34 ± 1.29 cm2 to 2.31 ± 1.25 cm2 in group 1 (p < 0.001), and from 6.52 ± 1.20 cm2 to 4.79 ± 1.17 cm2 in group 2 (p < 0.001). The percentage changes of ulcers area in group 1 (64.21 ± 17.94%) were statistically significantly greater as compared to group 2 (25.87 ± 14.07%) (p < 0.001). After treatment, the decrease in pain relief in group 1 was statistically significantly higher in comparison to group 2 (p = 0.006), while pain intensity after treatment decreased statistically significantly in both compared groups of patients (p < 0.001).

CONCLUSIONS

Magneto-LED therapy and magnetostimulation caused significant reduction of surface area of the treated venous leg ulcers and pain intensity, yet magneto-LED therapy was more efficient. Both evaluated methods also significantly reduced pain intensity.

Varicose Veins and the Diagnosis of Chronic Venous Disease in the Lower Extremities

Varicose veins usually present in the superficial veins of the lower extremities and are one of the main clinical presentations of chronic venous disease (CVD). Patients' symptoms may vary according to the pathophysiology, location, and severity of CVD. The prevalence of CVD in Korea has been increasing gradually. However, due to its broad clinical spectrum and the subjective nature of its diagnosis using ultrasound, discrepancies in diagnostic and treatment quality may exist among treating physicians. There have been recent efforts to improve the quality of the diagnosis and treatment of varicose veins in Korea by standardizing the diagnostic criteria and the indications for treatment. This study is a comprehensive review of the clinical manifestations and diagnostic criteria of CVD based on the most recent international and domestic guidelines and reports.

Iatrogenic Venous Compression Syndrome Following Bilateral Hip Arthroplasty: A Unique Case of Bilateral Femoral Vein Compression in a Patient With May-Thurner Syndrome

Iatrogenic venous compression syndrome is defined by extrinsic vein compression due to medical hardware, particularly relevant after joint replacement surgeries. Inserting medical hardware can lead to immediate risks such as deep vein thrombosis and pulmonary embolisms due to local tissue inflammation. The long-term issues include venous insufficiency due to chronic vessel irritation, subsequently causing intimal proliferation and thickening. Despite the existing knowledge of venous compression syndromes, iatrogenic cases are severely underreported. Here, we present a unique case of bilateral common femoral vein compression in a patient with May-Thurner syndrome and prior bilateral hip arthroplasty. An 85-year-old man with a history of venous insufficiency and bilateral hip arthroplasty for osteoarthritis presented with bilateral leg edema. Unsuccessful sclerotherapy and radiofrequency ablation led to a referral to a vascular specialist for venous duplex scans, venograms, and intravascular ultrasound. May-Thurner syndrome was revealed in the left common iliac vein, prompting the deployment of an 18 mm × 16 mm stent. Subsequently, during a venogram, what initially appeared to be a vasospasm in the left common femoral vein was diagnosed as extrinsic iatrogenic venous compression due to acetabular hip screws. This was found after two IV injections of 400 mg nitrogen and one balloon angioplasty could not resolve the compression. After advancement over a 0.35" microwire and accurate positioning over the center of the left common femoral vein lesion, a 16 mm × 90 mm stent was deployed. The venogram and intravascular ultrasound also showed a similar compression in the right common femoral vein. Another 400 mg IV nitrogen did not expand the lesion, so it was concluded that there was similarly an iatrogenic venous compression of the right common femoral vein, also due to acetabular hip screws in the right femur. A follow-up was scheduled a couple of weeks later to address the issue in the right common femoral vein. The underreported issue of iatrogenic venous compression following joint replacements highlights the need for better recognition and management of vascular complications due to inflammation and intimal proliferation. This is especially the case in high-risk patients, such as those with May-Thurner syndrome.

Effectiveness of herbal drug Terminalia Arjuna in chronic venous insufficiency - A prospective observational study

INTRODUCTION

Chronic venous insufficiency (CVI) manifests in various clinical presentations ranging from asymptomatic but cosmetic problems to severe symptoms, such as lower limb edema, skin trophic changes, and ulceration. CVI substantially affects the quality of life and work productivity of the patients. Ayurveda, an ancient traditional medicine in India, evaluates the various pathological stages of CVI with a wide range of pathological conditions such as Siragranthi (venous abnormalities), Raktavaritavāta (disorders of vāta occluded by rakta ∼ blood), ApanaVaigunya (vitiated apānavāyu), Arsha (hemorrhoids), VataRakta (rheumatism due to rakta), Kushtha (integumentary disease) and Dushta Vrana (putrefied wound) depending upon the presentations of the patient. Ayurvedic texts mention Terminalia arjuna as a potential herb for treating various conditions related to the circulatory system. The drug is an effective anti-inflammatory, anti-oxidant, and anti-hypertensive and has a definite role in improving cardiovascular hemodynamics and wound healing. These attributes suggest that the potential of Terminalia arjuna needs to be explored as a promising venoactive drug.

METHODS

This prospective observational study included 25 patients (31 limbs) with CVI who were treated with Tab Terminalia arjuna (Bark extract of Terminalia arjuna in a dose of 500 mg, given twice a day) and were observed on two visits on day 30 and day 90. Follow-up was carried out for three months to evaluate post-treatment complications or adverse effects. The clinical outcome assessment was done using Venous Clinical Severity Score (VCSS), and clinical grading was performed using clinical classification (C0 - C6) of CEAP (Clinical-Etiology-Anatomy-Pathophysiology) classification.

RESULTS

The median VCSS score (of both limbs) during the third visit was comparatively lower than the first, with a statistically significant improvement at 0.05 level. Further, there was a substantial positive improvement in the clinical classification of CEAP among the patients in pre and post treatment phase.

CONCLUSION

The prospective observational study shows that Tab Terminalia arjuna is safe and effective in CVI, reducing the symptoms like pain, edema, inflammation, pigmentation, induration and also expediting ulcer healing.

Vascular Diseases in Women: Do Women Suffer from Them Differently?

According to the World Health Organization, cardiovascular disease (CVD) is the leading cause of death among women worldwide, yet its magnitude is often underestimated. Biological and gender differences affect health, diagnosis, and healthcare in numerous ways. The lack of sex and gender awareness in health research and healthcare is an ongoing issue that affects not only research but also treatment and outcomes. The importance of recognizing the impacts of both sex and gender on health and of knowing the differences between the two in healthcare is beginning to gain ground. There is more appreciation of the roles that biological differences (sex) and sociocultural power structures (gender) have, and both sex and gender affect health behavior, the development of diseases, their diagnosis, management, and the long-term effects of an illness. An important issue is the knowledge and awareness of women about vascular diseases. The risk of cardiovascular events is drastically underestimated by women themselves, as well as by those around them. The purpose of this review is to draw attention to improving the medical care and treatment of women with vascular diseases.

Exploring causal correlations between inflammatory cytokines and varicose veins: A Mendelian randomization analysis

This study aimed to investigate the causal relationship between inflammatory cytokines and the risk of varicose veins. The data were sourced from genome-wide association studies (GWAS) of European individuals. Multiple Mendelian randomization (MR) methods were used to evaluate the association between inflammatory cytokines and varicose veins. The study found significant associations between elevated levels of certain inflammatory biomarkers (e.g., CASP-8, Vascular endothelial growth factor A levels (VEGF_A)) and an increased risk of varicose veins, while others (e.g., 4EBP1, MMP-10) showed a protective effect. The MR-Egger Intercept and heterogeneity tests indicated no significant pleiotropy or heterogeneity. This comprehensive MR analysis identifies several cytokines as potential contributors to the pathogenesis of varicose veins, offering insights into novel therapeutic targets. Our findings underscore the importance of inflammation in varicose veins and suggest that targeting specific cytokines could be a promising strategy for the treatment and prevention of varicose veins.

Factors Influencing Venous Remodeling in the Development of Varicose Veins of the Lower Limbs

One of the early symptoms of chronic venous disease (CVD) is varicose veins (VV) of the lower limbs. There are many etiological environmental factors influencing the development of chronic venous insufficiency (CVI), although genetic factors and family history of the disease play a key role. All these factors induce changes in the hemodynamic in the venous system of the lower limbs leading to blood stasis, hypoxia, inflammation, oxidative stress, proteolytic activity of matrix metalloproteinases (MMPs), changes in microcirculation and, consequently, the remodeling of the venous wall. The aim of this review is to present current knowledge on CVD, including the pathophysiology and mechanisms related to vein wall remodeling. Particular emphasis has been placed on describing the role of inflammation and oxidative stress and the involvement of extracellular hemoglobin as pathogenetic factors of VV. Additionally, active substances used in the treatment of VV were discussed.

Pathophysiology and Genetic Associations of Varicose Veins: A Narrative Review

Varicose veins (VVs) have a high prevalence worldwide and have become a major medical burden. Their pathophysiology involves a complex interplay of inflammation and tissue remodeling, and current treatment is limited by its impact on the pathophysiological mechanisms. In addition, despite clear environmental factors, family history is an important risk factor, suggesting a genetic component to the risk of developing VVs. Our understanding of the pathogenesis of these diseases has benefited greatly from the expansion of population genetic studies, from pioneering family studies to large genome-wide association studies; we now find multiple risk loci for each venous disease. This review considers the pathophysiology of VVs, highlighting the current state of genetic knowledge. We also propose future directions for research.

Azygos vein stenting as an alternate route for inferior vena cava obstruction

Chronic venous insufficiency, caused by inferior vena cava occlusion, can lead to thromboembolic complications and tissue loss. We present two cases of azygos vein stenting (AVS) in which vena cava recanalization techniques were exhausted. In the first case, the left iliac vein and vena cava were recanalized and stented; however, the right iliac vein had been previously resected and required AVS. Conventional recanalization attempts from the right and left iliac systems failed in the second patient with congenital inferior vena cava occlusion; therefore, AVS was chosen to establish in-line drainage.

Clinical observations in treatment of lower extremity varicose veins with trigger points acupuncture

OBJECTIVES

To observe the effect of the acupuncture of myofascial trigger points (MTrPs) in the treatment of lower extremity varicose veins (LEVVs).

METHODS

Overall, 260 patients with LEVVs participated in this study. LEVVs were selected based on diagnostic criteria of Clinical, Etiology, Anatomy, and Pathophysiology levels 2-5 and classified into six types on the basis of their anatomical positions. The MTrPs in the lower extremities were localized in accordance with the classification of LEVVs and treated by MTrPs acupuncture combined with self-massage and self-stretching. The interval between each treatment was 2 weeks to 1 month, depending on needling pain tolerance of each patient. An in-house evaluation was used to estimate the proportion of varicose veins in the lower limbs and their accompanying symptoms. The treatment effect was evaluated before each treatment and at 1-year follow-up.

RESULTS

The mean evaluation score of LEVVs before the treatment course was 3.66 ± 1.19. After the course, this reduced to 1.18 ± 0.97, with the following response rates: 85% for excellent and good and 15% for medium. After 1-year follow-up, the mean evaluation score of all patients was 1.11 ± 0.92, with the following response rates: 87% for excellent and good, and 13% for medium.

CONCLUSIONS

In some patients, MTrP acupuncture could cure LEVVs and its accompanying symptoms. These LEVVs are probably caused by fascia tension as a pre-pathology induced by the MTrPs.

Risk of osteoporosis among individuals with varicose veins: a multi-institution cohort study

The present study showed a significant association between varicose veins and the development of osteoporosis, especially women and patients older than 50 years. Physicians should be alerted to this issue and consider screening for osteoporosis in patients with varicose veins.

PURPOSE

Osteoporosis might be associated with many skin diseases. However, only a paucity of data addressing the association between varicose veins and subsequent osteoporosis development. The study was aimed to evaluate whether there is an increased risk of osteoporosis among patients with varicose veins.

METHODS

This multi-institution database study was based on Chang Gung Research Database from January 1, 2003, to December 31, 2015. Patients aged 20 years and older with varicose veins were enrolled. Participants in the control group were selected by matching in a 4:1 ratio by sex, age, index date, and comorbidities. The hazard ratios associated with osteoporosis were estimated using Cox regression analysis with competitive risk model. Incidence rate of osteoporosis was assessed in individuals with and without varicose veins.

RESULTS

A total of 11,959 patients with varicose veins and 47,633 matched controls were enrolled in the study. The varicose veins group had higher incidence rates than the control group for osteoporosis (46.40 vs 31.92 per 10,000 person-years; adjusted HR 1.481 [95%CI, 1.314-1.669; P < 0.001]). Compared with matched controls, varicose veins patients with or without venous ulcers had 1.711- and 1.443-times increased risk of developing osteoporosis, respectively. Subgroup analysis showed varicose veins were associated with osteoporosis in women and patients older than 50 years.

CONCLUSION

The present study demonstrated individuals with varicose veins had an increased risk of osteoporosis. Physicians should be alerted to this issue and consider screening for osteoporosis in patients with varicose veins, especially among women and patients older than 50 years.

A Narrative Review of Advancements in Understanding and Treating Varicose Veins

Chronic venous disease, with varicose veins as its archetypal manifestation, stands as a pervasive and intricate health quandary, encompassing a vast array of contributing factors. Age, genetics, obesity, pregnancy, and prolonged immobility weave a complex tapestry, underscoring the omnipresence of this ailment. Its societal and economic footprint is undeniably formidable, as diverse classifications underscore its multifaceted character. The intricate interplay of chronic venous disease with diabetes mellitus and neuropathy compounds the challenge, fostering soaring healthcare expenditures and a palpable erosion of quality of life, particularly among women harboring cardiometabolic risk factors. Despite research shedding light on heightened susceptibility within certain demographics, the enigmatic determinants orchestrating the transition from mild to severe chronic venous disease continue to elude us. Varicose veins, marked by the presence of dilated and tortuous subcutaneous vessels, precipitate both physical discomfort and cosmetic concerns, frequently necessitating meticulous clinical evaluation coupled with ultrasound studies to secure a precise diagnosis. Treatment strategies are strategically crafted to ameliorate distressing symptoms, enhance aesthetic concerns, and forestall potential complications. Nevertheless, the prognostication of chronic venous disease remains ensconced in a degree of ambiguity, hinting at the vast terrain yet to be charted in this medical domain. The quest to fathom the intricacies of this condition uncovers an ever-evolving panorama where conservative interventions play an indispensable role in managing mild cases, while interventional procedures like endovenous laser ablation and sclerotherapy step onto the stage for patients grappling with severe symptoms, thus treading the fine line between efficacy and invasiveness. Moreover, a meticulous economic analysis underscores the cost-effectiveness of various therapeutic modalities, thereby bolstering the imperative of a patient-centered approach. As we navigate the labyrinthine complexities of chronic venous disease and varicose vein management, we are inexorably drawn to the pivotal role of customized treatment approaches, as well as the dynamic interplay between scientific progress, patient preferences, and therapeutic innovations in the relentless pursuit of optimized outcomes and an enhanced quality of life.

Severity of Chronic Venous Insufficiency on Primary Total Knee Arthroplasty Outcomes

BACKGROUND

More than 700,000 people in the United States undergo total knee arthroplasty (TKA) each year. Chronic venous insufficiency (CVI) affects 5% to 30% of adults, sometimes resulting in leg ulceration. These CVI cases in TKAs have been associated with worse outcomes; however, we found no study differentiating CVI severity.

METHODS

This retrospective study analyzed TKA outcomes at one institution from 2011 to 2021 using patient-specific codes. Analyses included short-term complications (< 90 days postoperative), long-term complications (< 2 years), and CVI status (yes/no; simple/complex/unclassified). Complex CVI consisted of pain, ulceration, inflammation, and/or other complications. Revisions within 2 years and readmissions within 90 days post-TKA were assessed. Composite complications included short-term and long-term complications, revisions, and readmissions. Multivariable logistic regressions predicted complication (any/long/short) as a function of CVI status (yes/no; simple/complex) and potential confounding variables. Of 7,665 patients, 741 (9.7%) had CVI. Among CVI patients, 247 (33.3%) had simple CVI, 233 (31.4%) had complex CVI, and 261 (35.2%) had unclassified CVI.

RESULTS

There was no difference in CVI versus control in composite complications (P = .722), short-term complications (P = .786), long-term complications (P = .15), revisions (P = .964), or readmissions (P = .438) postadjustment. Composite complication rates were 14.0% without CVI, 16.7% with complex CVI, and 9.3% with simple CVI. Complication rates differed between simple and complex CVI (P = .035).

CONCLUSION

Overall, CVI did not affect postoperative complications versus control. Patients who have complex CVI are at higher risk for post-TKA complications compared to those who have simple CVI.

Prevalence and associated factors of chronic venous disease among the modern Iranian urban population

OBJECTIVES

Chronic venous disease (CVD) of the lower extremities is one of the common venous diseases in different populations, with a wide range of clinical manifestations and undetermined exact prevalence owing to different population characteristics and measurement methods. This study aimed to estimate the prevalence of CVD among the modern Iranian urban population and determine its associated risk factors.

METHODS

The Heart Assessment and Monitoring in Rajaie Hospital study, a longitudinal population-based cohort, aims to investigate the baseline prevalence and the 10-year incidence of cardiovascular diseases and associated risk factors in the adult population aged 30 to 75 years with no overt cardiovascular diseases in Tehran. Two instructed interventional cardiologists performed CVD evaluation using the Clinical-Etiology-Anatomy-Pathophysiology classification. CVD was graded as C1 to C6, and chronic venous insufficiency (CVI) as C3 to C6. A multivariable regression model was used to analyze the association between CVD and prespecified covariates of age, sex, body mass index (≥30 kg/m2), smoking, hypertension, diabetes mellitus, physical activity, dyslipidemia, and delivery method.

RESULTS

CVD prevalence among 1176 participants was 36.5% (95% confidence interval [CI], 33.8-39.3) and was higher in women than men (44.2% vs 23.5%). CVI prevalence was only 0.7% (95% CI, 0.3-1.3). Multivariable analysis showed that advanced age (odds ratio [OR], 1.06; 95% CI, 1.04-1.08), female sex (OR, 2.98; 95% CI, 2.14-4.14), and body mass index of ≥30 (OR, 1.36; 95% CI, 1.03-1.81) were independently associated with CVD. Physical activity (OR, 0.77; 95% CI, 0.58-1.02) was nearly protective, whereas other factors, including traditional cardiovascular risk factors, had no meaningful association with CVD.

CONCLUSIONS

Our findings showed that CVD was prevalent in the modern Iranian urban population. However, considering the very low prevalence of the higher stages of the disease, the benefit of mass screening is debatable, and better risk discriminators should be investigated.

Effect of short-term compression therapy after thermal ablation for varicose veins: study protocol for a prospective, multicenter, non-inferiority, randomized controlled trial

BACKGROUND

For patients with varicose veins, the goal is to relieve pain and swelling, reduce the severity of edema, improve skin changes, and heal ulcers associated with venous disease. Compression therapy is the cornerstone of their management. Several studies have shown that wearing an elastic bandage for the first 24 h and then a compression stocking for a week can effectively reduce the pain after thermal ablation. However, in clinical practice, patient compliance with this treatment could be better, considering difficulties in pulling up and removing the compression stocking, tightness, and skin irritation because these must be worn for a prolonged period. A potential solution to battling these barriers is short-term compression therapy. Besides, the effect and necessity of wearing compression stockings after thermal ablation have been questioned. Based on current clinical experience and limited evidence, although some scholars have suggested that compression therapy may be an unnecessary adjunctive therapy after thermal ablation, there is still a great deal of uncertainty in the absence of compression therapy after thermal ablation compared to compression therapy. Therefore, we advocate further research to evaluate the clinical effect of short-term postoperative compression therapy. Furthermore, well-designed randomized controlled trials are needed.

METHODS

A prospective, multicenter, non-inferiority randomized controlled trial is designed to evaluate the non-inferiority of target vein occlusion rate at 3 months. Three hundred and sixty patients will be randomly assigned in a 1:1 ratio to one of the following treatments: (A) 3 M™ Coban™ elastic bandage for 48 h or (B) 3 M™ Coban™ elastic bandage for the first 24 h and then a class II compression full-length stocking (23-32 mm Hg) for 1 week. The two groups will be compared on several variables, including target vein occlusion rate at 3 months (primary outcome indicator), pain, quality of life, clinical severity of varicose veins, postoperative complications, time to return to regular work, and compliance.

DISCUSSION

Suppose the effect of the 3 M™ Coban™ elastic bandage for 48 h proves to be non-inferior to long-term compression therapy. In that case, this short-term treatment may contribute to a future update of clinical guidelines for compression therapy after thermal ablation of varicose veins, resulting in higher patient compliance and better postoperative quality of life.

Comparison of Radiofrequency Ablation and Saphenous Vein Stripping for the Treatment of Recurrent Lower Extremity Venous Insufficiency

OBJECTIVE

To compare the efficiency and safety of radiofrequency ablation (RFA) and saphenous vein stripping (SVS) for the treatment of recurrent lower extremity chronic superficial venous insufficiency (CSVI).

METHODS

Patients who underwent SVS and RFA for recurrent lower extremity CSVI following RFA and patients who had 2-year follow-up results were enrolled into the study. Total, 37 patients who underwent a second RFA session with 2-year follow-up results were available. Then 37 patients were selected from 88 patients who underwent SVS for recurrent lower extremity CSVI to achieve a 1:1 ratio for comparison. Groups were compared based on preoperative properties, operative parameters, postoperative outcomes, complications and follow-up results.

RESULTS

Duration of the procedure was 20.7 minutes in the RFA group and 30.7 minutes in the SVS group (P = .001). Postoperative pain at first hour, sixth hour and 24th hour were significantly lower in patients who underwent RF (P = .001 for each parameter). Moreover, hospitalization time (18.1 hours vs 24.6 hours, P = .001) and time to return to normal daily activities (1.6 days and 2.5 days, P = .001) were significantly shorter in the RFA group. Success of the procedure did not statistically significant at first year follow-up (P = .304). However, success was significantly higher for the SVS group at second year follow-up (73% for RFA group and 91.9% for SVS group, P = .032).

CONCLUSION

We achieved significantly shorter procedure time, less postoperative hospitalization time, and a shorter time to return to daily activities with RFA. In contrast, the success rate of SVS was significantly higher at the second year follow-up, but not the first year follow-up in comparison with RFA.

Venous ulcers: look at the patient, not at the ulcer! Risk factors and comorbid conditions in venous ulcers of lower limbs

BACKGROUND

In venous leg ulcers (VLU), risk factors and comorbidities may affect prognosis and recurrence. Aim of this paper was to assess risk factors and most frequent medical conditions in venous ulcers.

METHODS

This a single center retrospective study from January 2017 to December 2020 on 172 patients with VLU admitted at our Center for Ulcer therapy in San Filippo Neri Hospital in Rome; data about medical history, Duplex scanning results and lifestyle questionnaire were collected in an Excel database and evaluated with Fisher test. Patients with lower limbs arterial insufficiency were excluded.

RESULTS

Incidence of VLU in patients over 65 was twice that in patients under 65 and woman were affected by VLU more than men (59.3% vs. 40.7%; P<0.001); more significant comorbidities were arterial hypertension in 44.19% (P=0.06), heart disease in 35.47% (P<0.001), chronic obstructive pulmonary disease (COPD) in 16.28% (P=0.008). In 33 patients (19% of cases) a trauma caused the ulcer. Diabetes, obesity, chronic renal insufficiency and orthopedic disease do not seem to have a direct influence on VLU.

CONCLUSIONS

Age, female sex, arterial hypertension, heart disease and COPD were significant risk factors. Thinking "globally" to the patient rather than only taking the ulcer into account is the key for a long-lasting therapeutic result; comorbidities are interconnected so weight loss, an exercise program for calf pump and compression must all be part of the VLU therapy, not only to heal the existing ulcer but also to prevent recurrences.

Outcome of preventive nursing intervention, prophylactic anticoagulation and the use of the Caprini score on venous thromboembolism after varicose vein surgery

Objective

This research was devoted to estimate the outcome of preventive nursing intervention on venous thromboembolism (VTE) after varicose vein surgery in lower extremities.

Methods

A total of 516 subjects with varicose veins of lower extremities (from January 2020 to January 2022) treated in our hospital were separated into observation subgroup (n = 258) and control subgroup (n = 258) at random. The conventional nursing intervention was applied in the control subgroup, preventive nursing intervention, prophylactic anticoagulation and the use of Caprini score was applied in the observation subgroup. The levels of blood indexes [hemoglobin (Hb), platelet (PLT) and D-dimer (D-D)] were compared between the two subgroups before operation and 7 days postoperative, the occurrence of subcutaneous congestion, lower limb swelling and pain, VTE and nursing satisfaction of the subject 4 (four) weeks after discharge.

Results

After intervention, the levels of PLT and D-D in the observation subgroup were notably lower than those in the control subgroup. Four weeks after discharge, the incidence of subcutaneous congestion, lower limb swelling and pain, there had no notable difference in two subgroups Versus the control subgroup, VTE in the observation subgroup was notably lower and nursing satisfaction was higher.

Conclusion

Preventive nursing intervention can reduce the level of PLT and D-D, restrain in the incidence of VTE and improve the nursing satisfaction of subjects with varicose veins of lower extremities after varicose vein surgery of lower limb.

The effect of wound electrical stimulation in venous leg ulcer healing-a systematic review

OBJECTIVE

The benefit of using electric stimulation therapy (EST) to heal venous leg ulcers (VLUs) is not well established. The main aim of this systematic review was to evaluate the effects of ulcer EST in VLU healing.

METHODS

A systematic search of the literature was conducted using the databases PubMed, Scopus, and Web of Science and included original studies that reported VLU healing after EST. The inclusion criteria were at least two surface electrodes placed on or near the wound or a planar probe covering the ulcer area to be treated. The Cochrane risk of bias tool for randomized control trials (RCTs) and Joanna Briggs Institute critical appraisal checklist for case series were used to evaluate the risk of bias.

RESULTS

This review included eight RCTs and three case series involving a total of 724 limbs in 716 patients with VLUs. The mean patient age was 64.2 years (95% confidence interval, 62.3-66.2), and 46.2% (95% confidence interval, 41.2%-50.4%) were men. The active electrode was placed on the wound with the passive electrode placed on healthy skin (n = 6), the two electrodes were placed on either side of the wound edges (n = 4), or a planar probe was used (n = 1). The pulsed current was the most used waveform (n = 9). The change in the ulcer size was the main method used to determine ulcer healing (n = 8), followed by the ulcer healing rate (n = 6), exudate levels (n = 4), and the time to healing (n = 3). Five RCTs detected a statistically significant improvement in at least one VLU healing outcome, after EST compared with the control group. In two of these, EST was better than the control but only for patients who had not undergone surgical treatment of VLU.

CONCLUSIONS

The findings from the present systematic review support the use of EST to accelerate wound healing of VLUs, especially for patients who are not surgical candidates. However, the significant variation in electric stimulation protocols represents an important limitation to its use and should be addressed in future studies.

Efficacy and safety of ultrasound-guided foam sclerotherapy combined with endoluminal radiofrequency closure in patients with varicose veins of lower extremities

We aimed to explore the efficacy and safety of ultrasound-guided foam sclerotherapy combined with endoluminal radiofrequency closure in patients with varicose veins of lower extremities (VVLEs); furthermore, we aimed to provide a theoretical basis for the effective management of VVLE patients in clinical work. From January 1, 2020, to March 1, 2021, 88 patients with VVLE admitted to Third Hospital of Shandong Province were included in this retrospective study. Depending on the type of treatment, the patients were divided into study groups and control groups. The study group consisted of 44 patients who were given ultrasound-guided foam sclerotherapy combined with endoluminal radiofrequency closure. The control group consisted of 44 patients who were given high ligation and stripping of the great saphenous vein. Efficacy indicators included postoperative venous clinical severity score (VCSS) of affected limb and postoperative visual analogue scale (VAS) score. Safety indicators included length of operation, intraoperative blood loss, length of postoperative rest in bed, length of hospital stay, postoperative heart rate, preoperative blood saturation (SpO2 ), preoperative mean arterial pressure (MAP), and complications. The VCSS score 6 months after operation in the study group was significantly lower than that in the control group (P < .05). The pain VAS score in the study group was significantly lower than that in the control group at 1 and 3 days after operation (both P < .05). Compared with the control group, the study group was significantly lower in length of operation, intraoperative blood loss, postoperative in-bed time, and hospital stays (all P < .05). Heart rate and SpO2 were significantly higher, and MAP was significantly lower in the study group compared with that in the control group 12 hours after surgery (all P < .05). The overall postoperative complication rate in the study group was significantly lower than that in the control group (P < .05). In conclusion, compared with surgical treatment of high ligation and stripping of the great saphenous vein, ultrasound-guided foam sclerotherapy combined with endoluminal radiofrequency ablation for the treatment of VVLE disease has better efficacy and safety, which is worthy of clinical promotion.

The impact of invasive treatment of superficial venous insufficiency of the lower extremities on cardiac functions

OBJECTIVE

The aim of the study was to investigate the effect of invasive treatment for chronic venous insufficiency (CVI) on cardiac hemodynamics.

METHODS

Fifty three patients diagnosed with saphenofemoral junction or great saphenous vein insufficiency in a level above C3 according to Clinical-Etiology-Anatomy-Pathophysiology classification were included in the study. All the patients underwent 2D echocardiography before and 3 months after the invasive treatment.

RESULTS

In postinvasive treatment echocardiographic assessment, significant decreases in right ventricular end-diastolic diameter (p = 0.006), TAPSE (p = 0.006), tricuspid E wave velocity (p = 0.004), tricuspid E/A ratio (p < 0.001), sPAB (p = 0.017), tricuspid lateral s' wave velocity (p = 0.004), and right ventricular free wall longitudinal strain rate (p = 0.011) were observed.

CONCLUSIONS

The invasive treatment of superficial venous insufficiency of the lower extremities may lead to reduction in the increased venous return in the supine position subclinically.

An ultrasound imaging and computational fluid dynamics protocol to assess hemodynamics in iliac vein compression syndrome

OBJECTIVE

Elevated shear rates are known to play a role in arterial thrombosis; however, shear rates have not been thoroughly investigated in patients with iliac vein compression syndrome (IVCS) owing to imaging limitations and assumptions on the low shear nature of venous flows. This study was undertaken to develop a standardized protocol that quantifies IVCS shear rates and can aid in the diagnosis and treatment of patients with moderate yet symptomatic compression.

METHODS

Study patients with and without IVCS had their iliac vein hemodynamics measured via duplex ultrasound (US) at two of the following three vessel locations: infrarenal inferior vena cava (IVC), right common iliac vein, and left common iliac vein, in addition to acquiring data at the right and left external iliac veins. US velocity spectra were multiplied by a weighted cross-sectional area calculated from US and computed tomography (CT) data to create flow waveforms. Flow waveforms were then scaled to enforce conservation of flow across the IVC and common iliac veins. A three-dimensional (3D), patient-specific model of the iliac vein anatomy was constructed from CT and US examination. Flow waveforms and the 3D model were used as a basis to run a computational fluid dynamics (CFD) simulation. Owing to collateral vessel flow and discrepancies between CT and US area measurements, flows in internal iliac veins and cross-sectional areas of the common iliac veins were calibrated iteratively against target common iliac flow. Simulation results on mean velocity were validated against US data at measurement locations. Simulation results were postprocessed to derive spatial and temporal values of quantities such as velocity and shear rate.

RESULTS

Using our modeling protocol, we were able to build CFD models of the iliac veins that matched common iliac flow splits within 2% and measured US velocities within 10%. Proof-of-concept analyses (1 subject, 1 control) have revealed that patients with IVCS may experience elevated shear rates in the compressed left common iliac vein, more typical of the arterial rather than the venous circulation. These results encourage us to extend this protocol to a larger group of patients with IVCS and controls.

CONCLUSIONS

We developed a protocol that obtains hemodynamic measurements of the IVC and iliac veins from US, creates patient-specific 3D reconstructions of the venous anatomy using CT and US examinations, and computes shear rates using calibrated CFD methods. Proof-of-concept results have indicated that patients with IVCS may experience elevated shear rates in the compressed left common iliac vein. Larger cohorts are needed to assess the relationship between venous compression and shear rates in patients with IVCS as compared with controls with noncompressed iliac veins. Further studies using this protocol may also give promising insights into whether or not to treat patients with moderate, yet symptomatic compression.

The first meta-analysis research on the effects of endovenous laser ablation combined with sapheno-femoral junction high ligation of the great saphenous vein

Endovenous laser ablation (EVLA) is a common minimally invasive technique used to treat varicose veins. The most commonly used laser wavelengths for EVLA/EVLT of varicose veins are 810 nm and 1470 nm. The laser pulse frequency is typically set to continuous wave (CW) mode, with a pulse duration of a few milliseconds (ms) delivered in a radial mode. The energy delivered per pulse is typically set between 40 and 120 Joules, with a power setting of 10 to 30 watts and an intensity setting of 40 to 120 J/cm2. The controversy exists regarding the benefits of performing saphenofemoral junction (SFJ) ligation prior to EVLA to decrease the recurrence rate of varicose veins. This meta-analysis aims to investigate the effectiveness of combining EVLA with high ligation versus using EVLA alone in treating lower extremity varicose veins. We conducted a systematic search of four databases from their inception until July 1, 2022, for randomized controlled trials and prospective controlled trials evaluating the advantages and disadvantages of EVLA with or without high ligation for the treatment of lower extremity varicose veins. In analyzing binary data, rate difference (RD) is used, while odds ratio (OR) is used for evaluating the confidence interval (CI) of binary data. A P value of less than 0.05 is deemed statistically significant. Heterogeneity is assessed using the chi-square test. If the I2 statistic, which reflects statistical heterogeneity, is greater than 50%, a random-effects model should be used. In the absence of significant statistical heterogeneity, a fixed-effects model should be used if I2 is less than 50%. We used the Cochrane risk-of-bias tool to assess the quality of the studies and Review Manager 5.4 for the primary and secondary outcome analysis. The meta-analysis was conducted in accordance with the Cochrane Handbook. There were no significant differences in the rate of major complications (RR = 1.63; 95% CI, 0.40-6.69; P = 0.50) or in the frequency of minor complications (RR = 1.07, 95% CI, 0.87-1.31; P = 0.52) between the EVLA with high ligation (EVLA/HL) group and the EVLA group. However, the rate of vein occlusion was significantly lower in the EVLA group than in the EVLA/HL group (RR = 1.06; 95% CI, 1.03-1.09; P = 0.0004). Our meta-analysis indicates that combining EVLA with high ligation provides stable long-term clinical efficacy in treating varicose veins of the lower extremities, although it increases the invasiveness of the surgery. The use of EVLA alone may be less effective in preventing vein occlusion.

Part II: Cutaneous manifestations of peripheral vascular disease

In this Part 2 of a 2-part continuing medical education series, we review the epidemiology of peripheral vascular disease, its association with cutaneous symptoms, and the diagnosis and evaluation of cutaneous features of vascular disorders. As peripheral vascular disease becomes more prevalent globally, it is essential for dermatologists to become competent at accurately recognizing and diagnosing cutaneous manifestations and directing individuals to receive appropriate care and treatment.

Rate of saphenous vein occlusion and side effects at 1 year follow up after 1470 nm endolaser

Background

Use of endolaser for chronic venous disease involves choosing the laser wavelength and optical fiber to use and the quantity of energy to be administered. Efficacy is assessed by the venous occlusion rate and safety is evaluated in terms of side effects.

Objectives

To determine the incidence of total post-endolaser saphenous vein occlusion at 1-year follow-up. To describe side effects and their incidence and rates of reintervention or supplementary treatment during the postoperative period.

Methods

A retrospective, observational cohort study with a quantitative approach, enrolling patients with saphenous vein incompetence treated with intravenous 1,470 nm laser ablation. Data were input to an MS Excel 2019 spreadsheet, calculating means and standard deviations with the software's Power Query supplement.

Results

38 patients and 104 venous segments were eligible for the study. 100% were occluded at 30 days and 99.04% were still occluded at 1 year after the procedure. Mean Linear Endovenous Energy Density administered to the internal saphenous vein was 2,040.52 W/cm/s with standard deviation of ± 1,510.06 W/cm/s and 1,168.4 W/cm/s with standard deviation of ± 665.011 W/cm/s was administered to the external saphenous vein. Pain along the saphenous path was the most common side effect, with eight cases (21.05%), followed by one case of paresthesia (2.63%).

Conclusions

The total occlusion rate at 1-year follow-up suggests the technique is promising and is currently applicable in this sample. The incidence of pain and paresthesia may be caused by the high mean energy delivered in some cases. It is recommended that multicenter studies be conducted with larger and more uniform samples in terms of their Clinical-Etiological-Anatomical-Pathological classifications.

Case Report: Successful results of direct varicose vein ablation with EVLA in chronic venous insufficiency patient in Indonesia

Background: Varicose veins are considered a chronic venous disease. Delaying treatment might cause several late complications that contribute to a high burden on healthcare systems. It may be treated with endovenous laser ablation (EVLA) and stab avulsion as additional procedures. Varicose direct ablation has been promoted to replace stab avulsion in certain conditions. Here we report the case of a 71-year-old female who presented with chronic venous insufficiency managed by an endovascular therapeutic approach using direct varix ablation for the first time in National Cardiovascular Center - Harapan Kita, Jakarta, Indonesia. Case report: A 71-year-old female came to the outpatient clinic with a large bulging vein in her leg. Duplex ultrasound showed that the great saphenous vein (GSV) was incompetent with a varicose vein in the medial part of proximal GSV below the knee. The patient underwent EVLA with direct varicose ablation using Utoh's technique. Duplex sonography evaluation showed the right GSV was utterly obliterated, including the varicose vein. The patient was discharged two days after the procedure without significant complaints nor pain medication. Conclusions: Direct varicose ablation was proposed as a better alternative than stab avulsion. The varicose vein can be managed with EVLA without a scalpel, incision, avulsion, or phlebectomy. In this case presentation, the endovascular therapeutical approach with Utoh's ablation technique showed promising results, and no complication was found in the patient.

Comparison of Foam and Liquid Sclerotherapy for the Treatment of Lower Extremity Varicose Veins and Telangiectasia in Obese Patients

OBJECTIVE

Sclerotherapy is an accepted treatment modality for reticular varicose veins and telangiectasia. We aimed to compare the success and safety of foam and liquid sclerotherapy in obese patients with lower extremity varicose veins and telangiectasia.

METHODS

The present study was performed in a non-randomized prospective manner, and obese patients with lower extremity varicose veins (patients with anatomy and pathophysiology classification {CEAP} class C1) and telangiectasia treated with foam sclerotherapy and liquid sclerotherapy were enrolled into the study. Patients treated with foam sclerotherapy and liquid sclerotherapy were compared with regard to preoperative parameters, procedure success, Visual Analog Score (VAS), patient satisfaction, and complications.

RESULTS

The VAS scores at the first hour and sixth hour were statistically higher in the foam sclerotherapy group (p=0.001 and p=0.001, respectively). The success rate after the first session was 88.2% in the foam sclerotherapy group and 69.4% in the liquid sclerotherapy group (p=0.008). After all sessions, the success rates were similar between groups (p=0.607). The foam sclerotherapy group required an average of 1.1 sessions, while the liquid sclerotherapy group required 1.4 sessions (p=0.001). At the third-month follow-up, the success rate was significantly higher in the foam sclerotherapy group than liquid sclerotherapy group (91.2% and 77.4%; p= 0.030). In the foam sclerotherapy group, 80.9% of the patients were very satisfied, while this rate was 58.1% in the liquid group (p=0.012). The rates of ecchymosis and hyperpigmentation in the first week after the procedure were significantly higher in the foam sclerotherapy group (p=0.003 and p=0.040, respectively).

CONCLUSION

Our findings showed that foam sclerotherapy had a significantly higher success rate after the first session, and third month follow-up with higher patient satisfaction. In contrast, liquid sclerotherapy had significantly lower VAS scores in the first and sixth hours following the procedure and had lower ecchymosis and hyperpigmentation in the first week after the procedure.

Quality of Life of Patients With Chronic Venous Insufficiency of the Lower Extremities Before and After Endovascular Laser Ablation: A Prospective Pilot Study Using the Chronic Venous Insufficiency Quality of Life Questionnaire 20 (CIVIQ-20)

Background Chronic venous insufficiency of the lower extremities is a condition in which blood stagnates in the venous system, causing symptoms of pain, fatigue, leg edema, and cramps. Although this disease progresses slowly and is not fatal, its symptoms lead to a decline in quality of life, affecting the patient's work. One of the current surgical treatment methods for patients with indications for surgical removal of the saphenous vein is endovenous laser ablation (EVLA). After EVLA, besides evaluating the effectiveness of surgery, and the rate of complications, one of the aspects that need attention is improving quality of life. The objective of this study was to assess the quality of life of patients with chronic venous insufficiency of the lower extremities before and after endovascular laser intervention, analyzing changes in ChronIc Venous Insufficiency Quality of Life Questionnaire 20 (CIVIQ-20) scores in each domain of quality of life. Methodology A total of 41 patients with chronic venous insufficiency of the lower extremities were enrolled in this study, who were classified as C2 to C6 and were treated by endovenous laser ablation. QoL was measured by using the ChronIc Venous Insufficiency Quality of Life Questionnaire 20 (CIVIQ-20) questionnaire pre- and post-operatively. Pain scores and clinical severity were also evaluated using the visual analog scale (VAS) and the venous clinical severity score (VCSS) one month after EVLA. Results The mean age was 52.17 ± 11.23 years. The mean duration of symptoms was 7.29 ± 3.58 years, the median laser ablation time was 40 minutes, and the mean time to return to normal activities was 5.7 ± 1.8 days. The CIVIQ-20 score at baseline was 47.8 ± 7.4 and 31.1 ± 3.9 after one-month laser ablation. The quality of life has significantly improved after intervention using laser treatment (p < 0.001). The VAS and VCSS scores after laser treatment were lower than the baseline (p < 0.001). In our study, there was a statistically significant correlation between the change of CIVIQ-20 and the change of VCSS (r = 0.63, p < 0.001). Conclusion CIVIQ-20 is a reliable toolkit to assess the quality of life of patients with chronic venous insufficiency of the lower extremities. The patient's quality of life improved markedly after the intervention.
