Abstract
The Brazilian Society of Angiology and Vascular Surgery has set up a committee to provide new evidence-based recommendations for patient care associated with chronic venous insufficiency. Topics were divided in five groups: 1. Classification, 2. Diagnosis, 3. Conservative or non-invasive treatment, 4. Invasive treatment and 5. Treatment of small vessels. This last series is closely related to the activities of Brazilian angiologists and vascular surgeons, who are heavily involved in the treatment of small superficial veins. These guidelines are intended to assist in clinical decision-making for attending physicians and health managers. The decision to follow a guideline recommendation should be made by the responsible physician on a case-by-case basis taking into account the patient's specific condition, as well as local resources, regulations, laws, and clinical practice recommendations.

J Vasc Surg Venous Lymphat Disord 2023; 11:1130-1138. [PMID: 37579944 DOI: 10.1016/j.jvsv.2023.06.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2023] [Revised: 05/04/2023] [Accepted: 06/08/2023] [Indexed: 08/16/2023]
Abstract
OBJECTIVE Remaining symptoms after treatment of superficial venous incompetence is a common problem. Duplex ultrasound is often used during follow-up, but does not permit an overall quantification of venous function. We have developed a plethysmographic method using occlusion cuffs for separation of superficial and deep venous reflux. By assessing the superficial component it is possible to quantify a potential suboptimal hemodynamic treatment in patients with superficial venous incompetence. The aim was to examine whether patients with hemodynamically quantifiable remaining reflux after treatment experience impaired clinical outcomes. METHODS This single-center prospective cohort study evaluated 156 limbs with great saphenous vein incompetence treated with radiofrequency ablation or high ligation and stripping. Duplex ultrasound and strain-gauge plethysmography (SGP) with and without selective superficial occlusion were performed before and one-year after treatment. Time taken (seconds) to reach 50% of the venous volume (T50) was evaluated. A difference in the T50of >5 seconds between postoperative strain-gauge plethysmography with and without superficial occlusion was defined as remaining reflux. The Venous Clinical Severity Score (VCSS) and Aberdeen Varicose Vein Questionnaire (AVVQ) were evaluated and compared between patients with and without remaining reflux. Multivariable logistic regression was used to evaluate risk factors for remaining plethysmographic reflux. RESULTS In all patients, median (25th, 75th percentile) T50 increased preoperatively from 7 seconds (3, 12 seconds) to 17 seconds (11, 28 seconds) (P < .001) 1 year after treatment. The VCSS and AVVQ were reduced (VCSS, 8.0 [6.0, 10.0] vs 3.0 [1.0, 5.0] [P < .001]; AVVQ, 21.8 [15.8, 32.1] vs 6.4 [2.2, 11.0] [P < .001]). Of the 156 limbs, 87 (56%) demonstrated remaining reflux 1 year after treatment. Patients with remaining plethysmographic reflux displayed higher median (25th, 75th percentile) VCSS (3.0 [2.0, 5.0] vs 2.0 [1.0, 4.0]; P = .012) and AVVQ (7.5 [2.7, 14.9] vs 4.7 [1.6, 9.2]; P = .025). Multivariate logistic regression showed that higher preoperative C in the Clinical Etiology Anatomy Pathophysiology classification (CEAP) (odds ratio [OR], 2.9 [95% confidence interval [CI], 1.34-6.46), age (OR, 1.03; 95% CI, 1.001-1.065), small saphenous vein incompetence (OR, 4.2; 95% CI, 1.30-13.73) and postoperative great saphenous vein reflux below the treated area (OR, 2.16; 95% CI, 1.02-4.56) were significant risk factors for remaining plethysmographic reflux. CONCLUSIONS A majority of treated limbs showed quantifiable reflux 1 year after intervention and these patients displayed worse patient related outcomes assessed with the VCSS and AVVQ. Remaining plethysmographic reflux was associated with preoperative small saphenous vein incompetence and reflux below the treated area as well as advanced age and higher C in CEAP.

Abstract
Objectives To evaluate the relation of quantitative Duplex ultrasound (DUS) and strain gauge plethysmography (SGP) parameters with clinical severity and quality of life in patients with superficial venous incompetence. Methods DUS volume flow and distal SGP refilling times (T50 and T90) were evaluated in 152 patients (164 Limbs) with superficial incompetence. Clinical severity and quality of life were evaluated with C of the CEAP classification, venous clinical severity score (VCSS), Aberdeen varicose vein questionnaire (AVVQ), and EuroQol 5D-3L. Results Higher DUS volume flow was associated with higher C in CEAP scores. Volume flow was also related to T50 and T90. Shorter T50 and T90 were associated with higher C in CEAP and VCSS. T50 was also associated with EQ-5DVAS. Reflux extension to the foot wase associated with shorter T50 and T90 and higher DUS volume flow. Conclusions DUS volume flow and SGP refilling times are related with clinical severity and provide quantitative information regarding venous function in patients with superficial incompetence.

Venous Segmental Flow Changes after Superficial Venous Intervention Demonstrating by Quantitative Phase-Contrast Magnetic Resonance Analysis: Preliminary Data from a Longitudinal Cohort Study.

Abstract
The effects of superficial venous intervention on hemodynamics can be quantified using two-dimensional phase-contrast magnetic resonance imaging (2D PC-MRI). Twelve patients received pre- and postintervention 2D PC-MRI analysis using quantitative hemodynamic parameters. Fifteen healthy volunteers served as controls. The 2D PC-MRI results of the target limbs (limbs scheduled for intervention for venous reflux) differed from those of the controls in terms of stroke volume (SV), forward flow volume (FFV), absolute stroke volume (ASV), and mean flux (MF) in all venous segments. The velocity time integral (VTI) and mean velocity (MV) of the popliteal vein (PV) segments were similar between the target limbs and controls preoperatively. After intervention, the target limbs exhibited an increase in VTI and MV in the femoral vein (FV) and PV segments. We compared the target and nontreated limbs of the individual patients preoperatively and postoperatively to minimalize individual bias. All QFlow parameter ratios in the FV segment increased after venous intervention (VTI, p = 0.025; MV, p = 0.024). In the PV segment, FFV and ASV increased significantly (p = 0.035 and 0.024, respectively). After interventions, the volume (FFV and ASV) of the PV segment and the efficiency (VTI and MV) of the FV segment significantly increased.

Abstract
ABSTRACT To compare the effectiveness and patient comfort between two methods that block superficial venous blood flow during the thrombolytic treatment of lower extremity deep venous thrombosis (DVT) to provide evidence that informs clinical choice.One hundred twenty patients with lower extremity DVT were randomly divided into sphygmomanometer (group A, n = 40), tourniquet (group B, n = 40), and control group (no blocking, n = 40). All the patients were treated with a daily dosage of urokinase using a dial sphygmomanometer cuff and tourniquet to block lower extremity superficial vein blood flow. The pressure of the dial sphygmomanometer blocking lower extremity superficial vein blood flow was measured during lower extremity venography. Leg swelling reduction rate, venous patency, thrombus removal rate, and average comfort index were observed during the blocking process.The average pressure value for group A was 70 ± 10 mm Hg. The differences in the swelling reduction rate and venous patency were significant between the groups. Comparing the two groups at different time points, the average thrombus clearance rate of group A was higher than that of group B and control group. The leg pain scores of group A were lower than those of group B and control group. The postoperative comfort ratio of group A was higher than that of group B, and the proportion of severe discomfort in group A was lower than that in group B.Compared with the tourniquet, using a dial sphygmomanometer cuff to block lower extremity superficial vein blood flow achieved a better thrombolytic effect on DVT and provided higher patient comfort during treatment.

Abstract
Objectives To evaluate postoperative venous haemodynamics and quality of life after treatment of great saphenous vein (GSV) incompetence. Methods Radiofrequency ablation and high ligation and stripping were performed in 62 patients (65 limbs) and 58 (65 limbs), respectively. Phlebectomies were performed in both modalities. Strain-gauge plethysmography on the foot combined with superficial venous occlusion was used to measure refilling time after knee bends. Strain-gauge plethysmography, duplex ultrasound and quality of life were assessed before and one month after treatment. Results Duplex ultrasound displayed successful intervention in all but two limbs. Refilling time increased similar in radiofrequency ablation and high ligation and stripping after treatment ( p < 0.001). Postoperatively, strain-gauge plethysmography detected remaining reflux in 71% of the patients. Multivariate analysis showed that two or more incompetent calf branches were associated with remaining reflux (OR 4.82 (95% CI: 1.33–17.5), p = 0.02). No difference in quality of life was seen in patients with remaining reflux. Conclusions Despite successful treatment, a majority of the limbs showed remaining reflux, in which incompetent calf branches appear to play an important role.
