Gender Differences in Iliofemoral Vein Stenting for Chronic Venous Insufficiency.

INTRODUCTION: Little is known about gender's role in chronic venous insufficiency (CVI). The aim of this study was to evaluate the impact of gender on outcomes of iliac vein stenting(IVS) for CVI. METHODS: 866 patients who underwent vein stenting for CVI at one institution from August 2011 to June 2021 were analyzed via retrospective review. Patients were followed up to 5 years after initial stent placement. Presenting symptoms were quantified using Venous Clinical Severity Score(VCSS), Clinical Assessment Score(CAS), and Clinical, Etiology, Anatomy, and Pathophysiology (CEAP) class. Reoperations after initial IVS were recorded. Major reoperations were defined as iliac interventions using venography. Minor reoperations were defined as thermal ablation. Multivariate logistic regression models were used determine odds of any and major reintervention. RESULTS: Compared to females, males pre-operatively presented with a higher mean CEAP class (3.6 vs .3.3; P < .001), VCSS composite (11.3 vs .9.9; P < .001), and smoking history (134 vs .49; P < .001). The 2 groups were similar in age (P = .125), BMI(P = .898), previous DVT (P = .085), diabetes (P = .386), hypertension (P = 1.0), and CAD (P = .499). Multivariate analyses revealed no association between gender and any reintervention (OR, 1.02; 95%CI, .71-1.46; P = .935) or gender and major reintervention (OR, 1.39; 95% CI, .86-2.23 P = .177). There were no differences in number of stents placed (P = .736) or symptomatic improvement at 1 month (P = .951), 3 months (P = .233), 6 months(P = .068), and greater than 1 year (P = .287). At the 1 year follow-up, the male cohort had higher CAS values than females P = .034). Males had larger reduction in composite VCSS than women at 1 year (5.1 vs. 3.8; P = .003) and 3 years (5.3 vs .3.7; P = .031) of follow-up and similar levels of improvement in post-op (4.0 vs .3.5; P = .059), 2 years (4.3 vs .3.8; P = .295), 4-years (5.1 vs .4.6; P = .529), 5 years (5.6 vs .4.2; P = .174), and 6 years (5.93vs.3.3 P = .089). CONCLUSIONS: In a single site study of IVS in patients with CVI, males tended to present worse symptoms than females. After surgery, however, both cohorts showed improvement, and both seemed to improve to the same degree of residual symptoms.

Non-randomized comparative study of three methods for great saphenous vein ablation associated with mini-phlebectomy; 48 months clinical and sonographic outcome.

Background: Varicose veins are one of the earliest clinical features of superficial venous insufficiency (SVI) of the lower limbs that affects around 20-40% of the population with a lot of burden on patients' quality of life (QoL) and health systems if left untreated. They are defined as subcutaneous veins in the lower extremities which are dilated to ≥3 mm in diameter in the upright position and retrograde flow of >0.5 s in duration. (VVs) could occur in the great saphenous vein (GSV) or small saphenous vein (SSV) and/or in any of their tributaries. Methods: A prospective non-randomized comparative study for three methods of treatment of varicose veins was conducted. All symptomatic varicose veins with Clinical, Etiological, Anatomical, Pathophysiological (CEAP) Clinical classes of 2 or greater and demonstrated venous reflux with a duration of 0.5 s or greater on duplex ultrasound imaging GSV larger than 10 mm in diameter by duplex ultrasound were included. Results: A total of 150 patients with 183 legs in all three groups are treated. The mean age of the patients in all groups was comparable (37.32) years, and a total of 87% were women. Demographic and preoperative clinical features, presentations, and anatomic characteristics were comparable in all groups. Disfigurement was the main presenting complaint in all. All postoperative complications were significantly higher in the group of surgery over 48 months of follow up the degree of satisfaction measured by VCSS score was highest among the RFA group followed by the EVLA group. Conclusion: The results of our study suggest that the long-term results of endovenous thermal ablation methods (EVLA, RFA) are superior to open surgery for the management of varicose veins, with the RFA group showing better results in terms of improvement in QoL based on VCSS compared to the EVLA group.

Summary of diagnostic and characteristic parameters of C0 to C2 patients based on the CEAP2020 classification.

OBJECTIVES: Hemodynamic changes in C0 to C2 according to the clinical/etiological/anatomical/pathophysiological classification have not been analyzed extensively. We intend to investigate the characteristics of early stage venous disease using venous clinical severity score (VCSS), heaviness/ache/swelling/throbbing/itching (HASTI) score and duplex ultrasound (DUS) derived parameters. METHODS: From Aug. 2020 to Jul. 2021, consecutive patients were categorized according to the clinical/etiological/anatomical/pathophysiological 2020 classification. The vein diameter (mm), reflux time (s), cross-sectional area (cm2), peak and mean reflux velocity (cm/s), and total reflux volume (mL) were documented in the superficial system and deep system. VCSS and HASTI scores were assessed and DUS parameters were analyzed. A P value of less than .05 was considered statistically significant. RESULTS: We studied 257 consecutive patients (142 female) with 371 limbs. The mean age was 50.96 ± 13.27 years (range, 20-81 years; median, 53 years) with an average body mass index of 24.03 ± 2.96 kg/m2 (range, 17.00-33.06 kg/m2; median, 23.67 kg/m2). The proportion of clinical (C) category was as followed: 47 C0S (12.67%), 45 C1 (12.13%), and 279 C2 (75.20%). There were 42.6% of C0 and 62.2% of C1 associated with some form of venous reflux, Pr (pathology [P]-reflux). Reflux of the great saphenous vein above the knee (GSVa) was the most commonly affected vein segment from C0-2. C1 differed from C0 only by age and severity scores with a cut-off value of 1 for both VCSS and HASTI. Larger saphenous veins diameter (GSV and small saphenous vein) were seen in Pr (P-reflux) than Pn (P-none) of C0 cases. Larger deep vein diameters (common femoral vein, femoral vein, and popliteal vein) were evident in Pr versus Pn of C1 cases. In C2, the popliteal vein, saphenofemoral junction, and GSVa were dilated in Pr cases. CONCLUSIONS: Both HASTI and VCSS were discriminative from C0 to C2. C0 differed from C1 by age and severity scores as DUS characteristics were not significantly different between the two groups. Vessel diameter played a discriminative role in distinguishing Pn versus Pr cases in each C0-2 category. GSVa was the most frequent reflux segment irrespective of reflux types.

The randomized, controlled ATLANTIS trial of aquatic therapy for chronic venous insufficiency.

OBJECTIVE: There are conflicting reports on the efficacy of exercise in chronic venous insufficiency (CVI). Exercise in water or aquatic activity (AA) can have additional advantages. We sought to evaluate the clinical effects of AA in CVI in a randomized prospective open label fashion. METHODS: A total of 201 patients with advanced CVI were randomized to receive AA vs no such treatment. In the Aquatic Group (AG), 91 patients reached the 24-month follow-up point, and in the Control Group (CG), 90 patients did. The primary efficacy end point was a predefined reduction of ≥4 points in the modified Venous Clinical Severity Score (VCSS) at 3 months. Instruments of venous disease severity and quality of life were compared at baseline, 3 months, and 24 months between and within the two groups. These included the modified VCSS, Villalta score, leg and thigh circumference, the Physical Health Component of the 36-Item Short Form Health Survey, and the Venous Insufficiency Epidemiological and Economic Study Quality of Life/Symptom scores. Aquatic activity consisted of a minimum of 15 minutes of walking in a swimming pool at 1 m/s, 3 times/wk for 3 months. RESULTS: The primary end point of 4-point reduction in the modified VCSS at 3 months was reached in 28% of AG and 3% of CG (odds ratio = 12.08; 95% confidence interval: 3.51, 41.59; P < .001). Comparison of changes in secondary end points from baseline to 24 months between AG and CG demonstrated the following: modified VCSS -4.08 ± 2.08 vs -1.15 ± 1.26, Villalta score -4.00 ± 2.68 vs -1.01 ± 1.34, thigh circumference -3.40 ± 1.78 cm vs -1.40 ± 2.55 cm, leg circumference -1.27 ± 1.34 cm vs -0.49 ± 1.21 cm, Physical Health Component of the 36-Item Short Form Health Survey 3.82 ± 2.36 vs 1.16 ± 1.18, Venous Insufficiency Epidemiological and Economic Study Quality of Life 3.35 ± 1.67 vs 1.30 ± 1.43, and Venous Insufficiency Epidemiological and Economic Study Symptom 3.53 ± 1.71 vs 1.23 ± 1.26 (P < .001 for all comparisons; ± denotes mean ± standard deviation). CONCLUSIONS: The addition of AA to the treatment of patients with advanced CVI is safe and effective, leading to a significant improvement in clinical status and quality of life. These beneficial changes occur rapidly within 3 months of initiation of AA and are continued at a slower rate of improvement from 3 months to 2 years.

Association between vein diameters, reflux characteristics, and clinical severity in patients with chronic venous insufficiency in Northwest China.

OBJECTIVE: Our goal was to summarize the relationship between vein diameters, reflux characteristics, and clinical severity in consecutive patients with chronic venous insufficiency (CVI) in Northwest China. METHODS: We evaluated 531 consecutive patients with CVI (249 women) who presented to the Department of Ultrasound of Xijing Hospital from September 2017 to July 2019. Reflux times and the mean diameters of the great saphenous, the small saphenous, and the calf perforator veins based on duplex ultrasound scans obtained in the standing position were recorded. Venous-specific assessment tools-the Heaviness, Achiness, Swelling, Throbbing, Itching (HASTI) score, the Venous Clinical Severity Score (VCSS), and the Clinical, Etiological, Anatomical, Pathophysiological (CEAP) class-were analyzed. Regression analysis was used to investigate the relationship between the clinical scores, vein diameters, and reflux times. A P value of less than .05 was considered statistically significant. RESULTS: We analyzed 531 consecutive patients with 728 limbs. The mean age was 55.24 ± 11.38 years; the mean body mass index (BMI) was 24.75 ± 3.49 kg/m2. Three hundred thirty-four patients (62.9%) presented with unilateral limb findings and 197 (37.1%), with bilateral limb involvement. No significant changes were noted in age and BMI across CEAP classes (F = 2.322 and F = 3.917, respectively; P > .05 for both). Both the HASTI score (r2 = 0.8741; P < .001) and the VCSS (r2 = 0.9257; P < .001) correlated with the CEAP class. The HASTI score strongly correlated with the mean diameters of the great saphenous and small saphenous veins (r2 = 0.9252, r2 = 0.6304, respectively; P < .001 for both) similarly to VCSS (r2 = 0.9396, r2 = 0.7195, respectively; P < .001 for both). The HASTI score and VCSS correlated equally with the mean diameters of the calf perforator veins (r = 0.7773 and r = 0.7781, respectively; P < .001 for both). In those with C6, both great saphenous vein (F = 4.608; P < .001) and small saphenous vein reflux times (F = 14.97; P < .001) were significantly higher than those in C1. Both the HASTI score and VCSS strongly associated with the reflux times of the great saphenous (r2 = 0.7706 and r2 = 0.8181, respectively; P < .001 for both) and small saphenous veins (r2 = 0.6470 and r2 = 0.7865, respectively; P < .001 for both). CONCLUSIONS: This analysis is one of the few epidemiologic studies of patients with CVI in Northwest China. Age and BMI did not correlate with CEAP class. Both the HASTI score and VCSS correlated strongly with the CEAP classification; vein diameters and reflux time in both the great saphenous vein and the small saphenous vein, indicating the validity of these outcome tools to venous hemodynamics and to CVI in general.

Behçet's disease; A rare refractory patient with vena cava superior syndrome treated with infliximab: a case report and review of the literature.

Objectives: Behçet's disease (BD) is a multi-systemic inflammatory disorder which can affect all types and sizes of vessels.The usage of TNF-α antagonists is increasing in different involvements of BD that is inadequately controlled by standard immunosuppressive regimens. Methods: Here we reported a rare BD case that is controlled by only infliximab (IFX) treatment. Results: A 24-years-old male patient was diagnosed as BD with recurrent oral and genital ulcerations,uveitis,femoral vein thrombosis and HLA-B5 positivity.He had had terminal ileitis,epididymitis,bilateral internal iliac artery aneurysm and superior sagittal sinus thrombosis after the diagnosis.He admitted to our outpatient clinic with dyspnea,orthopnea,chest pain and facial swelling.We detected facial edema,plethora,venous distention on neck and chest.We suspected vena cava superior syndrome(VCSS) and performed CT angiography that demonstrated high-grade vena cava superior stenosis and thrombus where SVC opens to the right atrium.Patient was anticoagulated with warfarin and a shunt was implanted between the left brachiocephalic vein and right atrium.Colchicine and interferon-alfa treatment were continued and 1mg/kg steroid was added.But the patients' symptoms relapsed one month later and his shunt was revised with balloon angioplasty.5mg/kg IFX was started.We  performed a CT-angiography annually for two years.VCSS and other symptoms of BD are resolved and have not relapsed yet. Conclusions: Vascular involvement of BD are generally treated with immunosuppressive agents such as steroids and immunomodulators.IFX was found effective and well tolerated in the treatment of intestinal,neurological and vascular involvement of BD especially in patients with poor response or intolerance to conventional therapy.This case report supports IFX as a new therapeutic option for patients with vascular BD.

Clinical outcomes after varicose vein procedures in octogenarians within the Vascular Quality Initiative Varicose Vein Registry.

BACKGROUND: Whereas chronic venous insufficiency and varicose veins (VVs) are a universally recognized problem, they are frequently underappreciated as major contributors to long-term morbidity in the elderly despite the increasing prevalence with age. Previous studies have demonstrated that chronic venous insufficiency and VV treatments in patients ≥65 years old yield an overall benefit; however, there have been few data as to whether octogenarians are undergoing these procedures and with what success. As such, our objectives were to investigate the procedures selected, to examine clinical outcomes after VV procedures in elderly patients ≥80 years old, and to explore complication rates (both systemic and leg specific) after VV procedures in patients ≥80 years old. METHODS: We performed a retrospective review using the Vascular Quality Initiative Varicose Vein Registry of all VV procedures performed for ≥C2 disease from January 2015 to February 2017. We divided all procedures into three age groups: patients <65 years, patients ≥65 to 79 years, and patients ≥80 years. Statistical testing included χ2 test for categorical variables and Student t-test for continuous variables. Two comparisons were performed: first, comparing patients <65 years old with patients ≥65 to 79 years old; and second, comparing patients ≥65 to 79 years old with patients ≥80 years old. RESULTS: There were a total of 12,262 procedures performed, with 8608 procedures in the patients <65 years, 3226 in patients 65 to 79 years, and 428 procedures in patients ≥80 years. A total of 22,050 veins were treated during the 12,262 procedures. Almost half of procedures (46.51%; n = 5703) had only one vein treated during a single procedure. Between age groups, the percentage of one vein treated increased as the patient's age increased, ranging from 45.39% (n = 3875) for patients <65 years to 48.55% (n = 1555) for patients between 65 and 79 years and 64.08% (n = 273) for patients ≥80 years. Patients in the group ≥80 years had an overall lower average body mass index and were more likely to be receiving anticoagulation and to undergo truncal procedures alone compared with the other groups. The group ≥80 years had a significant improvement in both Venous Clinical Severity Score (4.37 ± 4.16; P < .001) and patient-reported outcomes (8.79 ± 7.27; P < .001) from before to after the procedure. Overall complications were low in all age groups. The octogenarians had no higher risk of systemic complications. CONCLUSIONS: Vascular specialists are performing VV procedures in octogenarians and are more likely to perform truncal only therapy. In addition, octogenarians have statistically significant improvement of Venous Clinical Severity Score and patient-reported outcomes with a low risk of complications despite more advanced venous disease at presentation.

The relation between clinical scores and quality-of-life in long-term follow-up.

INTRODUCTION: Quality-of-life and severity scores are both popular measures in medicine. For deep venous obstruction, the VEINES-QOL/Sym and venous clinical severity score (VCSS) are widely used. Combining a patient-reported outcome with a clinical severity score should give a more sensitive outcome for treatment results. To establish and compare their suitability for deep venous disease, we compared the outcomes of both scores in a group of patients who were interventionally treated for deep venous disease. METHODS: The venous clinical severity scores and VEINES-QOL/Sym scores of a group of patients who had received interventional treatment for deep venous obstruction more than 12 months ago were compared at T0 and T12. RESULTS: Both the Spearman's rho and Pearson's r show a very weak, negative correlation (statistically significant (p ≤ 0.05)), between the venous clinical severity score and VEINES-QOL at T12 and between the venous clinical severity score and the VEINES-SYM at both T0 and T12. T0 VCSS-VSYM: rho = -0.219 (p = 0.052), r = -0.236 (p = 0.037), T12 VCSS-VQOL: rho = -0.459 (p = 0.007), r = -0.379 (p = 0.030), T12 VCSS-VSYM: rho = -0.463 (p = 0.007), r = -0.432 (p = 0.012). This negative correlation was not statistically (p ≥ 0.05) confirmed for T0 VCSS-VSYM. CONCLUSION: The physician-scored venous clinical severity score of patients treated for deep venous obstruction does not correlate well with their self-reported quality-of-life and symptom scores.
