Objectives Arteriovenous (AV) shunting has been postulated as the underlying cause of varicose veins. The aim of this study was to analyse pressure and oxygen content in primary varicose veins in order to determine evidence of arterial shunting. Methods Thirty-nine patients with varicose veins underwent cannulation of varicosities. The pressure and the blood oxygen content within varicosities were measured in different positions and during exercise. Similar measurements were made in the long saphenous veins of 10 control subjects without venous disease. Results Mean pressure in varicose veins in the supine position was 12.3 mmHg (Standard deviation [SD] 3.6 mmHg). Control subjects had similar pressures measured in the long saphenous vein. No pulsatile pressure tracings were obtained. Varicosity pressures in the erect position averaged 66 mmHg (SD 9 mmHg). In all cases, the pressure correlated with the distance of the varicosity from the heart. Pressure reduction in varicosities after exercise was significantly less than that in control subjects. Recovery time (RT 90) was also significantly shorter than in the control group. Mean venous pO2 in varicosities was 4.5 kPa (SD 1.0) in the supine position dropping to 3.9 kPa (SD 0.9) on standing; these values were not significantly different to samples from control subjects. Conclusions AV shunting is unlikely to be a causative factor in the development of primary varicose veins.

Objective To study the association of polymorphisms rs699947, rs2010963, rs3025039 in the VEGFA gene region and rs1870377, rs2305949, rs2071559 in the VEGFR2 gene region with the risk of primary varicose veins in ethnic Russians. Methods Genotypes were determined by real-time PCR allelic discrimination. The case group consisted of 448 patients with primary varicose veins and the control group comprised 609 individuals without a history of chronic venous disease. Association was studied by logistic regression analysis. Results Allele rs2010963 C was associated with the decreased risk of varicose veins (additive model of inheritance: odds ratio = 0.73, 95% confidence interval = 0.59–0.91, P = 0.004). Conclusions Our results provide evidence that polymorphism rs2010963 located in the 5′ untranslated region of the VEGFA gene can influence genetic susceptibility to primary varicose veins in Russians. Otherwise, it can be in linkage disequilibrium with another functional single nucleotide polymorphism that can alter the level of vascular endothelial growth factor A protein.

Objective To investigate the association of polymorphisms located near the FOXC2 gene with the risk of varicose veins in ethnic Russians. Methods Allele, genotype, and haplotype frequencies were determined in the sample of 474 patients with primary varicose veins and in the control group of 478 individuals without a history of chronic venous disease. Results Polymorphisms rs7189489, rs4633732, and rs1035550 showed the association with the increased risk of varicose veins, but none of the observed associations remained significant after correction for multiple testing. Haplotype analysis revealed the association of haplotype rs7189489 C–rs4633732 T–rs34221221 C–rs1035550 C–rs34152738 T–rs12711457 G with the increased risk of varicose veins (OR = 2.67, P = 0.01). Conclusions Our results provide evidence that the studied polymorphisms do not play a major role in susceptibility to varicose veins development in the Russian population.

Saphenofemoral Junction

Objectives Cellular senescence could play a role in the development of venous disease. Superficial venous reflux at the saphenofemoral junction is a common finding in patients with primary varicose veins. Furthermore, reflux in this essential area is associated with higher clinical stages of the disease and recurrent varicose veins. Therefore, this pilot study aimed to investigate cellular senescence in the immediate area of the saphenofemoral junction in patients with healthy veins, primary varicose veins and additionally in patients with recurrent varicose veins due to a left venous stump. Methods We analyzed vein specimens of the great saphenous vein immediately at the saphenofemoral junction. Healthy veins were collected from patients who underwent arterial bypass reconstructions. Samples with superficial venous reflux derived from patients who received high ligation and stripping or redo-surgery at the groin, respectively. Sections were stained for p53, p21, and p16 as markers for cellular senescence and Ki67 as a proliferation marker. Results A total of 30 samples were examined (10 healthy, 10 primary varicose, and 10 recurrent varicose veins). We detected 2.10% p53+ nuclei in the healthy vein group, 3.12% in the primary varicose vein group and 1.53% in the recurrent varicose vein group, respectively. These differences were statistically significant ( p = 0.021). In the healthy vein group, we found 0.43% p16+ nuclei. In the primary varicose vein group, we found 0.34% p16+ nuclei, and in the recurrent varicose vein group, we found 0.74% p16+ nuclei. At the p < 0.05 level, the three groups tended to be significant without reaching statistical significance ( p = 0.085). There was no difference in respect of p21 and Ki67. Conclusion We found significantly higher expression rates of p53 in primary varicose veins at the saphenofemoral junction than in healthy veins. p16 expression tended to be increased in the recurrent varicose vein group. These preliminary findings indicate that cellular senescence may have an impact in the development of varicose veins or recurrence. Further studies addressing this issue are necessary.

The reproducibility of venous volumetry has been evaluated in 20 normal legs (N), 20 legs with primary varicose veins (W) and 30 with stable post-thrombotic chronic venous insufficiency (CVI).The test has shown significant differences between the groups in mean relative expelled volume (EV rel, ccs): N 1.65 ± SD 0.66; W 1.01 ± 0.40; CVI 0.64 ± 0.39 and in half refilling time (T3 secs): N 23.9 ± 11.5; W 11.8 ± 7.4; CVI 3.6 ± 1.8. The percent coefficients of variation in tests repeated at intervals of up to a month were as follows.The reproducibility of the test confirms its value as a non-invasive means of measuring the severity of postthrombotic venous disease and thus as a means of assessing response to treatment. Serial volumetric tests on 25 patients before and for up to 12 months after Linton operations for chronic venous insufficiency show significant early improvements in expelled volume. But in many of these patients the refilling time tends to remain short indicating residual valvular incompetence and the possibility of clinical relapse in the long term.

Objectives To evaluate the effectiveness of compression stockings in controlling the varicose veins in pregnant women. Method A prospective controlled randomized clinical trial was performed, including 60 women: intervention group (n = 30), who used compression stockings, and control group (n = 30). Diameters of the great saphenous vein and small saphenous vein in the lower limbs of pregnant women in an orthostatic position were analyzed using Duplex-ultrasound. The symptomatology and CEAP were evaluated. Results Great saphenous vein diameters in the intervention group were 0.37 cm initial and 0.32 cm final (p < 0.0001) in the right leg and 0.28 cm and 0.38 cm (p < 0.0001) in the control group. CEAP classification presented worsening in the control group (p < 0.0001). The signs and symptoms in the control vs. intervention group: pain (86.67% vs. 23.33%; p < 0.0001), edema (70.00% vs. 33.33%; p = 0.0045), and leg heaviness (93.33% vs. 13.33%; p < 0.0001). Conclusions Compression stockings were effective in controlling the varicose veins related to pregnancy.

Aim This study examines the association between right heart diastolic function and clinical presentation of chronic venous disease and primary varicose veins of lower extremities. Material and methods We performed retrospective analysis of clinical, peripheral venous Duplex and tricuspid Doppler (early diastolic inflow E-wave, late diastolic inflow A-wave, ratios of E to A waves, early diastolic annular e′-wave, late diastolic annular a′-wave and systolic annular s′- wave) data of 85 patients, 133 legs with primary varicose veins. Results We found following significant (p-value < 0.05) associations between tricuspid Doppler and clinical presentation of chronic venous disease and primary varicose veins: Clinical Etiological Anatomical Pathophysiological clinical class influenced late diastolic inflow velocities (C6 class A-wave +11.2 cm/s or +27% in comparison with C2), late diastolic annular velocities (C6 class a′-wave +3.3 cm/s or +22% in comparison with C2), systolic annular velocities (C6 class s′-wave +3.7 cm/s or +27% in comparison with C2) and E/A ratios (C6 class E/A ratio −0.22 or −21% in comparison with C2). Recurrent varices in comparison with previously untreated are associated with significantly lower late diastolic inflow velocities (A-wave −4.4 cm/s or −9%) and preserved E/A ratios. Age significantly influenced tricuspid Doppler (E-, A-, e′-, a′-waves and E/A ratios) in patients with chronic venous disease. Conclusion Clinical presentation of primary varicose veins and chronic venous disease can be associated with the right heart diastolic function: C6 Clinical Etiological Anatomical Pathophysiological class in comparison with C2 is associated with increased right ventricular filling and impaired ventricular relaxation – right heart diastolic dysfunction; recurrent varices in comparison with previously untreated are associated with reduced right ventricular filling and preserved right heart diastolic function. Older age is the most important risk factor for varicose veins and chronic venous disease possible due to significant changes in right ventricular filling and in right heart diastolic function with age.

Abstract. Background: Chronic lower limb oedema is one of the complications of superficial or deep chronic venous disorders. It is ranked as “C3”on the CEAP classification. In epidemiological studies, the recognition of oedema is mainly based on clinical signs, and oedema is more easily detected in the second part of the day when it becomes evident. We addressed the question whether oedema is already present in the morning in patients suffering of primary varicose veins without trophic changes. Patients and methods: In total, 101 patients with primary varicose veins (C2 and/or C3 stage of the CEAP classification) and 122 controls were enrolled as they appeared in our centre. The consultation time was no later than 6 hours after the patient had woken up. Oedema was detected by pitting test and ultrasound. Results: The mean consultation time lapse was 3.7 ± 1.2 hours after waking-up. Oedema was more frequent in the group of primary varicose veins without trophic changes (36 % compared to 14 % in the control group; p < 0.01). Oedema was mainly detected by ultrasound and far less so by the pitting test. Conclusions: Patients with varicose veins have morning oedema more frequently than patients without varicosis and at a higher rate than in epidemiological studies.

Objective: To measure plasma lactoferrin as a marker of neutrophil degranulation in groups of patients with varying severity of venous disease and compare with age- and sex-matched control subjects. Design: Prospective study of patients with varicose veins compared with a group of control subjects with no history or clinical findings of varicose veins. Setting: The Middlesex Hospital Vascular Laboratory, Mortimer Street, London WIN 8AA, UK. Patients: Patients referred to the Middlesex Hospital Vascular Laboratory for investigation of venous disease. Control subjects were obtained from within the laboratory and hospital staff, and from a group of Patients attending the London Foot Hospital for routine chiropody. Neither group had arterial disease nor any other illness or medication known to alter white cell activity. Interventions: 10 ml of blood taken from an arm vein into EDTA for a neutrophil count and measurement of Plasma lactoferrin using an ELISA. Results: Significantly raised plasma lactoferrin was found in all four groups of patients compared with their controls ( p = 0.0156 for uncomplicated varicose veins, P = 0.01 for lipodermatosclerosis, p = 0.0413 for active venous ulceration, and p = 0.0005 for healed ulcers, Mann-Whitney U-test). Differences between medians (95% confidence interval) for the four groups were 269 (62–603), 199 (60–314), 133 (44–218) and 215 (98–349) ng/ml respectively. There was no difference in the neutrophil count between the patient and control groups, and correcting plasma lactoferrin for the neutrophil count did not remove significance in any group. Conclusions: This study shows evidence of increased neutrophil activation as shown by increased degranulation in patients with venous disease.

Cd34 Expression

Summary Objective: To study the CD34 expression in the leg veins with primary varicose veins. Material and Methods: The study included 18 patients with lower limbs varicose veins and deep vein valves insufficiency of C3 and C4 clinical classes (CEAP). To correct blood flow phlebectomy was accompanied by posterior tibial veins resection. Using immunohistochemistry, we compared the expression of CD34 in resected posterior tibial veins specimens and vena saphena magna distal fragment. Results: Posterior tibial veins wall in patients with lower limb varicosity and deep veins valves insufficiency vary the CD34 degree expression comparing with the control group. Total area of expression was significantly greater than in control sample. CD34 expression area was also significantly greater in vena saphena magna than in control group. CD34 expression comparison in the specimens from patients with varicose veins showed its significantly higher degree in the vena saphena magna than in tibial veins. Conclusion: With primary varicose veins superficial and deep leg veins develop unidirectional increase of CD34 expression, that can be assumed as a pathogenetic factors of further disease progression and involvement of deep vein valves.
