RESUMO

BACKGROUND: The term Anterior Accessory of the Great Saphenous Vein suggest this is a branch tributary vein despite this vessel's anatomic features of a truncal vein. A multisocietal group suggested to designate this the Anterior Saphenous Vein (ASV). This study was aimed to evaluate its ultrasound anatomy in normal and varicose limbs. METHODS: The clinical anatomy of the ASV was evaluated by narrative review of the literature. Additionally, the course of the ASV was evaluated in 62 limbs with no evidence of venous disease and 62 limbs with varicosities. RESULTS: The ASV length, patterns of origin and termination are reported in both normal and patients with varicose veins. Discussion of the patterns is supported by the narrative review of the literature. CONCLUSIONS: The ASV must be considered a truncal vein and its treatment modalities should be the same that for the great and small saphenous veins rather than a tributary vein.

RESUMO

BACKGROUND AND AIM: The biological behaviour of coronary graft conduits over time may be considered by serial angiography. METHODS: A single institution retrospective cohort received mostly clinically indicated angiography between 1997 and 2020, following coronary bypass surgery. Only perfectly patent grafts (absence of any lumen irregularity) for each conduit type at the first postoperative angiogram were selected for a later comparison. The latest angiograms were at least 5 years postoperatively, and at least 1 year after first postoperative angiogram. Analysis was done according to each graft (anastomosis). Comparisons used generalised estimating equations, adjusted for binary logistic regression. RESULTS: Of 143 patients, there were 410 of 468 (87.6%) perfectly patent grafts at the first angiogram, analysed at 6.8±4.0 years postoperative, of which 157 were internal mammary arteries, 228 were radial arteries, and 25 were saphenous veins. At the latest angiogram (12.2±3.8 years postoperative), comparison with the first angiogram for each individual graft found preserved perfect patency for internal mammary arteries, 156 of 157 (99.4%), and for radial arteries, 227 of 228 (99.6%) but saphenous veins deteriorated considerably, 13 of 25 (52.0%). The two arterial grafts (internal mammary and radial) were superior to vein grafts (odds ratio 163; 95% confidence interval [CI] 22-1,211; p<0.001), but not different from each other (odds ratio 0.95; 95% CI 0.78-1.16; p=0.584). CONCLUSIONS: From a position of known angiographic perfect patency post-CABG, internal mammary artery and radial artery grafts retained their perfect patency in the longer term, but saphenous vein grafts did not.

RESUMO

BACKGROUND: Our study aims to enhance the understanding of lymph node venous networks (LNVNs) by summarising their anatomical, sonographic features, and reflux patterns. METHOD: We examined 241 legs from 141 patients with primary chronic venous disease (CVD) using duplex ultrasound. RESULTS: The findings indicated variations in the shape, size, vascularity, and echogenicity of LNVN. The superficial inguinal lymph node with reflux appeared slightly larger, exhibiting higher velocities in the hilar artery. Regarding connections, venous flow within LNVN was predominantly drained through the saphenofemoral junction (SFJ), anterior accessory great saphenous vein (AAGSV), and great saphenous vein (GSV). A significant number of LNVNs were observed to be associated with anterolateral thigh tributaries. The study also identified valve cusps within LNVN. CONCLUSION: This study revealed a 12% prevalence of primary LNVN. Understanding the anatomical and haemodynamic features of LNVN informs treatment strategies and potentially helps prevent the recurrence of varicose veins.

RESUMO

BACKGROUND: Column interruption duration (CID) is a noninvasive surrogate for venous refill time (VFT), a parameter used in ambulatory venous pressure measurement. CID is more accurate than invasive VFT measurement because it avoids errors involved with indirect access of the deep system through the dorsal foot vein. The aim of this retrospective single center study is to analyze the clinical usefulness of CID in assessment of chronic venous disease (CVD). METHODS: A total of 1551 limbs (777 patients) were referred with CVD symptoms over a 5-year period (2018-2023); CID, air plethysmography, and duplex reflux data were analyzed. Of these limbs, 679 had supine venous pressure data as well. The pathology was categorized as obstruction if supine peripheral venous pressure was >11 mm Hg and as reflux if duplex reflux time in superficial or deep veins was >1 second. CID was measured via Doppler monitoring of flow in the great saphenous vein (GSV) and one of the paired posterior tibial (PT) veins near the ankle in the erect posture. The calf is emptied by rapid inflation cuff. CID is the time interval in seconds when cephalad venous flow in great saphenous vein and posterior tibial veins reappear after calf ejection. A CID <20 seconds in either vein is abnormal similar to the threshold used in VFT measurement. RESULTS: Thirty-two percent of the limbs had obstruction, 17% had reflux, and 37% had a combination; 14% had neither. Higher clinical-etiology-anatomy-pathophysiology (CEAP) clinical classes (C4-6) were prevalent in 44% of pure reflux, significantly less (P < .0001) than in pure obstruction (73%) or obstruction plus reflux subsets (72%), partly reflecting distribution of pathology. There is a progressive increase in supine venous pressure and abnormal CID (P < .0001 and P < .0001, respectively) in successive CEAP clinical class. No such correlation between CEAP and any of the reflux severity grading methods (reflux segment score, Venous Filling Index, and Kistner axial grading) was observed. Abnormal CID (55%) was more prevalent in higher CEAP classes (>4) (P < .0001) than in lesser clinical classes (0-2) or limbs with neither obstruction nor reflux (P < .01). CONCLUSIONS: Obstruction seems to be a more dominant pathology in clinical progression among CEAP clinical classes than reflux. CID is abnormal in both obstructive and refluxive pathologies and may represent a common end pathway for similar clinical manifestations (eg, ulcer). These data suggest a useful role for CID measurement in clinical assessment of limbs with CVD.

RESUMO

OBJECTIVE: Endothermal heat-induced thrombosis (EHIT) is a potential complication of radiofrequency ablation (RFA). Data on effective prophylaxis of EHIT are limited. In 2018, a high-volume, single institution implemented strategies to decrease the incidence of EHIT, including a single periprocedural prophylactic dose of low-molecular-weight heparin to patients with a great saphenous vein (GSV) diameter of ≥8 mm or saphenofemoral junction (SFJ) diameter of ≥10 mm and limiting treatment to one vein per procedure. The size threshold was derived from existing literature. The study objective was to evaluate the effects of these institutional changes on thrombotic complication rates after RFA. METHODS: A retrospective cohort control study was conducted using the Vascular Quality Initiative database. Data were collected for patients who underwent RFA with a GSV diameter of ≥8 mm or SFJ diameter of ≥10 mm from January 2015 to July 2022. The clinical end points were thrombotic complications (ie, thrombophlebitis, EHIT, deep vein thrombosis) and bleeding complications. Patient demographic and procedural variables were included in the analysis, and significant variables after univariable logistic regression were included in a multivariable logistic regression. RESULTS: After the policy change, the overall vein center EHIT rate decreased from 2.6% to 1.5%, with a trend toward significance (P = .096). The inclusion criterion of a GSV diameter of ≥8 mm or an SFJ diameter of ≥10 mm yielded 845 patients, of whom 298 were treated before the policy change and 547 after. There was a significant reduction in the rate of EHIT classified as class ≥III (2.34 vs 0.366; P = .020) after the institutional changes. Treatment of two or more veins and an increased vein diameter were associated with an increased risk of EHIT (P = .049 and P < .001, respectively). No significant association was found between periprocedural anticoagulation and all-cause thrombotic complications or EHIT (P = .563 and P = .885, respectively). CONCLUSIONS: The institutional policy changes have led to lower rates of EHIT, with a reduction in severe EHIT rates in patients with an ≥8-mm diameter GSV or a ≥10-mm diameter SFJ treated with RFA. Of the changes implemented, restricting treatment to one vein was associated with a reduction in severe EHIT. No association was found with periprocedural low-molecular-weight heparin, although a type 2 error might have occurred. Alternative strategies to prevent thrombotic complications should be explored, such as increasing the dosage and duration of periprocedural anticoagulation, antiplatelet use, and nonpharmacologic strategies.

RESUMO

BACKGROUND: To compare radiofrequency ablation (RFA) and cyanoacrylate closure (CAC) for large-diameter great saphenous vein (GSV) insufficiency between diameters of 12 and 16 mm. METHODS: This study is a single-center retrospective study. Subjects who underwent endovenous treatment with RFA (Group A) or CAC (Group B) for GSV insufficiency between June 2015 and June 2021 who were followed up for at least 2 years were included in the study. Subjects who had a 12-mm to 16-mm target vessel diameter and subjects with grade 3 and grade 4 reflux were included. Subjects' demographic data (age, sex), body mass indices, clinical, etiological, anatomic, pathophysiologic classification, GSV diameter, reflux grade, target vessel length, preoperative venous clinical severity score (VCSS), procedural time, postoperative first-day pain scores, postoperative 14th-day patient satisfaction scale, and postoperative complications were noted. In follow-up, subjects were evaluated with duplex ultrasonography and VCSS at 1, 6, 12, and 24 months. RESULTS: In total, 142 subjects were included (n = 71 for both groups). The mean GSV diameter was 13.21 ± 1.00 for Group A and 13.51 ± 0.97 for Group B. The groups did not differ in terms of age, sex, body mass index, clinical, etiological, anatomic, pathophysiologic classification, GSV diameter, reflux grade, target GSV length, preoperative VCSS, complications, postoperative 24-hr pain status or postoperative 14-day patient satisfaction scale (P > 0.05 for all comparisons). The procedure time was significantly shorter in Group B (34.68 ± 4.22 min for Group A vs. 22.59 ± 4.5 min for Group B, P = 0.001). In the 1-month and 6-month Duplex ultrasonography of the subjects, partial closure and patency rates in Group B were significantly higher than those in Group A (P = 0.003 and P = 0.025, respectively). At the 12-month and 24-month evaluation, closure rates did not show a statistically significant difference between the groups (P = 0.056 and P = 0.090, respectively). Preoperative and 1-month VCSS measurements did not show a statistically significant difference between groups (P > 0.05 for all comparisons). The 6-month, 12-month, and 24-month VCSS measurements of Group A were significantly higher than those in Group B. (P = 0.043, P = 0.009 and P = 0.002, respectively). CONCLUSIONS: Both RFA and CAC were found to be effective in the treatment of large-diameter GSV incompetency. The complication rates were similar between the 2 techniques. CAC had a shorter procedure time. Although the closure rates in the early postoperative period were better in the RFA group, long-term follow-up demonstrated similar patency rates. The functional results in the long-term follow-up were better in the RFA group.

RESUMO

OBJECTIVE: Superficial venous incompetence (SVI) is a common disease that causes significant quality of life (QoL) impairment. There is a need for more health economic evaluations of SVI treatment. The aim of this study was to perform a cost effectiveness analysis in patients with great saphenous vein (GSV) incompetence comparing radiofrequency ablation (RFA), high ligation and stripping (HL/S), and no treatment or conservative treatment with one year follow up. METHODS: Randomised controlled trial economic analysis from an ongoing trial; 143 patients (156 limbs) with GSV incompetence (CEAP clinical class 2 - 6) were included. Treatment was performed with RFA or HL/S. Follow up was performed up to one year using duplex ultrasound, revised venous clinical severity score (r-VCSS), Aberdeen Varicose Vein Questionnaire (AVVQ), and EuroQol-5D-3L (EQ-5D-3L). RESULTS: Seventy-eight limbs were treated with RFA and HL/S respectively. No treatment or conservative treatment was assumed to have zero in treatment cost and no treatment benefit. In the RFA group, one limb had reflux in the GSV after one month and three limbs after one year. In HL/S, two limbs had remaining reflux in the treated area at one month and one year. Both disease severity (r-VCSS, p = .004) and QoL (AVVQ, p = .021 and EQ-5D-3L, p = .028) were significantly improved over time. The QALY gain was 0.21 for RFA and 0.17 for HL/S. The cost per patient was calculated as €1 292 for RFA and €2 303 for HL/S. The cost per QALY (compared with no treatment or conservative treatment) was €6 155 for RFA and €13 549 for HL/S. With added cost for days absent from work the cost per QALY was €7 358 for RFA and €24 197 for HL/S. The cost per QALY for both methods was well below the threshold suggested by Swedish National Board of Health. CONCLUSION: RFA is more cost effective than HL/S and no treatment or conservative treatment at one year follow up.

RESUMO

The overall objective of this study was to construct a 3D neuroanatomical map of the saphenous nerve based on cartesian coordinate data to define its course in 3D space relative to bony and soft tissue landmarks. Ten lower limb embalmed specimens were meticulously dissected, digitized, laser scanned, and modelled in 3D. The course of the main branches, number of collateral branches, and relationship of saphenous nerve to the great saphenous vein were defined and quantified using the high-fidelity 3D models. In 60% of specimens, the saphenous nerve was found to have three branches in the leg, infrapatellar, anterior, and posterior. In 40% of specimens, the posterior branch was absent. Three landmarks were found to consistently localize the anterior branch: the medial border of tibia at the level of the tibial tuberosity, the medial border of tibia at the level of the mid-point of leg, and the mid-point of the anterior border of the medial malleolus. The posterior branch, when present, had variable branching patterns but did not extend as far distally as the medial malleolus in any specimen. Anatomically, the anterior and posterior branches at the level of the tibial tuberosity could be most advantageous for nerve stimulation due to their close proximity to the bifurcation of the saphenous nerve where the branches are larger and more readily localizable than distally. Additionally, the tibial tuberosity is a prominent landmark that can be easily identified in most individuals and could be used to localize the anterior and posterior branch using ultrasound or other imaging modalities. These findings will enable implementation of highly realistic computational models that can be used to simulate saphenous nerve stimulation using percutaneous and implanted devices.

RESUMO

BACKGROUND: Sparing the Great Saphenous Vein capital for possible arterial substitution and recurrence decrease may be an alternative to current ablation options for Varicose Veins treatment. Conservative surgery of varicose veins (CHIVA) was suggested in 1988 by Franceschi, by limited veins interruptions in strategic points. However, the method did not diffuse due to the need for high Duplex expertise to determine the procedure in every single patient. METHOD: Evaluation of the literature regarding saphenous sparing, with special reference to CHIVA. RESULT: It has been realized that basic Ultrasound expertise is sufficient for performing GSV conservation. Most of the time, only a few parameters are needed: a junction competence assessment and a re-entry perforator position. CONCLUSION: For achieving the goal of saphenous conservative treatment, a limited phlebectomy and possible Junction interruption (crossotomy) may be a simplified solution.

RESUMO

Different causes have been described for secondary lymphedema as reported in this article. A 75-year-old man was diagnosed with lymphedema about one decade after saphenous harvesting for coronary artery bypass surgery. It took two years for him to find out his diagnosis and receive the proper treatment. After standard complete decongestive therapy, his volume and pain decreased and his quality of life was improved, especially its physical aspect. It is important to recognize the possibility of lymphedema development after saphenous harvesting among patients undergoing coronary artery bypass surgery to prevent significant disturbance of quality of life with timely management.

RESUMO

PURPOSE: Saphenous vein grafts (SVGs) sometimes occur as vein graft stenosis or failure in coronary artery bypass grafting. The purpose of this study was to detect the factors affecting vein graft atherosclerosis. METHODS: We performed two analysis. In the first analysis, we enrolled 120 grafts using conventionally harvested saphenous vein graft (C-SVG) and followed-up with multiple coronary computed tomography angiography (CCTA). We examined the factors that contribute to the graft atherosclerosis defined by graft failure at subsequent CCTA or substantial progression of graft stenosis (a decrease of ≥0.6 mm in diameter). In the second analysis, 66 grafts using no-touch harvested saphenous vein graft (N-SVG) were compared with those in the first analysis using C-SVG, focusing on the differences in intraoperative factors using propensity score-matched analysis. RESULTS: In the first analysis, graft atherosclerosis+ group comprised 27 grafts, which had a larger SVG diameter, lower graft velocity, and higher graft/native ratio in diameter than the graft atherosclerosis- group. In the multivariable analysis, slow graft velocity and graft/native ≥2 in diameter were independently associated with the graft atherosclerosis. In the second analysis, the N-SVG group had a much greater graft velocity than the C-SVG group. CONCLUSION: Lower graft velocity and higher graft/native ratio in diameter were associated with the graft atherosclerosis. The N-SVG group had increased graft velocity, which may contribute to prevent the graft atherosclerosis.(Trial registration: UMIN Clinical Trial Registry no. UMIN000050482.

RESUMO

INTRODUCTION: Lower limb venous anomalies, including duplicated veins, are common and have significant impacts on the outcomes and efficacy of venous surgery. Digital subtraction angiography (DSA) guided venography, serving as the tertiary diagnostic option for venous disorders, offers valuable informations to clinical practitioners. PATIENTS AND METHODS: A retrospective study was conducted on 195 patients with suspected venous disease, evaluating 259 limbs with venography imaging. Two experienced interventional vascularists evaluated the images to determine the incidence and characteristics of variances in the femoral, popliteal, great saphenous, and small saphenous veins. Moreover, blood samples were collected to assess the safety of the venography procedure by monitoring changes in renal function. RESULT: Duplication variations were found in the lower limb veins, with the highest prevalence in the femoral vein (11.28%, 22/195), followed by the great saphenous vein (4.1%, 8/195), and the popliteal vein (1.54%, 3/195). No severe contrast agent allergies or postoperative complications were reported. No statistically significant differences were found in creatinine and urea levels pre- and post-operation for patients without duplication variations, those with duplication of the great saphenous, femoral, or popliteal vein (P < .05). CONCLUSION: DSA-guided venography is effective in identifying venous variations in lower limb disease. DFV is the most common recurrent vein, while DPV is the least. Adequate preparation ensures safety, high spatial resolution, dynamic imaging, and low tissue interference.

RESUMO

OBJECTIVE: Venous thromboembolism (VTE) occurs infrequently after endovenous laser ablation (EVLA). The purpose of this study was to assess the incidence of VTE after EVLA with and without pharmacologic prophylaxis. METHODS: From October 2019 to March 2020, a series of consecutive patients from the prospectively maintained VEINOVA (vein occlusion with various techniques) registry was retrospectively analyzed. All the patients underwent EVLA with and without postoperative thromboprophylaxis. A 1470-nm laser wavelength with a radial fiber was used for EVLA. Concomitant phlebectomy or sclerotherapy of insufficient tributaries was allowed. Perivenous tumescence was applied with 1% Rapidocaine (lidocaine hydrochloride monohydrate; Sintetica SA). Ablation of varicose veins was performed by continuously drawing back the laser fiber at a power of 10 W, aiming for a linear endovenous energy delivery of 60 to 90 J/cm. Compression stockings were applied postoperatively, and the patients were advised to wear them for 1 week. Duplex ultrasound was performed at the 1- and 4-week follow-up visits to determine the occlusion rate and the occurrence of EHIT and VTE. RESULTS: Overall, 249 patients were identified from the registry. Of the 249 patients, 26 were omitted because of treatment of recurrent varicose veins. Finally, 223 consecutive patients with 223 legs and 227 saphenous veins (159 great saphenous veins, 49 small saphenous veins, and 19 anterior accessory saphenous veins) were included in the final analysis. Their mean age was 58.1 ± 13.8 years, and 167 patients (73.1%) were women. The clinical CEAP (clinical, etiology, anatomy, pathophysiology) classification was C2 for 11 legs (4.9%), C3 for 123 legs (55.2%), C4a or C4b for 86 legs (38.6%), and C5 to C6 for 3 legs (1.4%). Thromboprophylaxis was given to 132 patients (59.2%) for 3 days (rivaroxaban 10 mg once daily to 130 patients [98.5%] and low-molecular-weight heparin to 2 patients [1.5%]). No thromboprophylaxis was administered to 91 patients (40.8%) after EVLA. The average treatment length was 34.2 ± 19.3 cm and the average diameter was 5.0 ± 1.3 mm. At 1 week of follow-up, no thrombotic event had occurred in either group. At 4 weeks of follow-up, one case of EHIT class 2 (1.1%) and one case of pulmonary embolism (1.1%) had occurred in the group without thromboprophylaxis. In the thromboprophylaxis group, one deep vein thrombosis (0.8%) event had occurred (adjusted P = .135). At 1 and 4 weeks of follow-up, the treated varicose veins remained occluded in both groups. CONCLUSIONS: Endovenous ablation of truncal varicose veins appears to be safe with a low thrombotic event rate with or without pharmacologic thromboprophylaxis. However, more data are needed before a final recommendation regarding the best thromboprophylaxis treatment option can be given.

RESUMO

BACKGROUND: Endovenous thermal ablation (EVTA) of the lower extremity veins has risen to become the main treatment modality for symptomatic venous reflux disease. One of the main reported side effects of EVTA is recanalization. As of today, there is no clear protocol as to when follow-up duplex ultrasound scans should be performed. However, the standard for postoperative duplex after truncal ablation is within 1 week of the procedure. Our aim is to try to find whether there is a particular time period when postoperative duplex ultrasound scans should be performed to allow us to best diagnose recanalization. METHODS: We retrospectively analyzed 9799 procedures in 3237 patients with chronic venous insufficiency owing to great, small, and anterior accessory saphenous vein insufficiency from 2012 to 2018. We excluded 466 perforator veins. All 9799 procedures were performed using EVTA in patients who failed to respond to conservative management initially. Postoperative duplex ultrasound scans were performed within 1 week (3-7 days postoperatively). We defined a successful obliteration as lack of color flow on postoperative scan. We defined symptomatic recanalization as presence of reflux on duplex ultrasound examination in the targeted vessel at follow-up with symptom recurrence. Follow-ups were performed every 3 months in the first year and every 6 months thereafter. RESULTS: Patient ages ranged from 15 to 99 years. The median patient age at the time of the procedures was 63 years (interquartile range [IQR], 51-73 years). The median overall follow-up was 25 months (IQR, 4-56 months). The Clinical, Etiology, Anatomy, and Pathophysiology (CEAP) class of all the procedures were: C1, 21; C2, 208; C3, 3585; C4, 4680; C5, 188; and C6, 1117. There were 145 redo procedures performed after symptomatic recanalization was diagnosed in patients. CEAP class of the redo patients were: C1, 0; C2, 2; C3, 49; C4, 70; C5, 5; and C6, 19. CONCLUSIONS: Most patients underwent a redo procedure performed within the first year after the initial procedure. Conversely, there was great variability as to when redo procedures were performed. Because there is no defined pattern as to when these symptomatic occurrences arise, it may not be required to perform postoperative duplex ultrasound scans after EVTA routinely, but instead when a patient comes back with symptoms such as swelling.

RESUMO

OBJECTIVE: The evidence for post-foam sclerotherapy compression stockings for varicose veins is limited. Thus, we examined the effects of post-procedural compression stockings on varicose vein patients undergoing foam sclerotherapy. METHODS: The CONFETTI study was a prospective, single-center, randomized controlled trial. Patients with foam sclerotherapy-suitable varicose veins were randomly assigned to the compression group (CG) or the no compression stockings group (NCG) for 7 days. The primary outcome was post-procedural pain measured on a 100-mm visual analog scale for 10 days. Secondary outcomes included clinical severity, generic and disease-specific quality of life scores, return to normal activities and/or work, occlusion rates, degree of ecchymosis, CG compliance, and complications. Patients were reviewed at 2 weeks and 6 months. RESULTS: A total of 139 patients were consented to and randomly assigned. The intention-to-treat analysis included 15 patients who did not receive the allocated intervention. Both groups had similar baseline characteristics. Of the patients, 63.3% and 55.4% returned for follow-up at 2 weeks and 6 months, respectively. Most of the veins treated were tributaries. The CG experienced significantly lower pain scores than the NCG, with median scores of 7 mm and 19 mm, respectively (Mann-Whitney U-test; P = .001). At 2 weeks, no differences were observed in ecchymosis or the time to return to normal activities or work. Both groups showed improvements in clinical severity and quality of life, and occlusion rates were comparable. The NCG experienced one deep venous thrombosis and superficial thrombophlebitis, whereas the CG experienced two superficial thrombophlebitis. CONCLUSIONS: The CONFETTI study suggests that short-term post-procedural compression stockings are beneficial for reducing post-procedure pain.

RESUMO

OBJECTIVE: Effective treatment options are available for chronic venous insufficiency associated with superficial venous reflux. Although many patients with C2 and C3 disease based on the CEAP (Clinical-Etiological-Anatomical-Pathophysiological) classification have combined great saphenous vein (GSV) and saphenofemoral junction (SFJ) reflux, some may not have concomitant SFJ reflux. Several payors have determined that symptom severity in patients without SFJ reflux does not warrant treatment. In patients planned for venous ablation, we tested whether Venous Clinical Severity Scores (VCSS) are equivalent in those with GSV reflux alone compared with those with both GSV and SFJ reflux. METHODS: This cross-sectional study was conducted at 10 centers. Inclusion criteria were: candidate for endovenous ablation as determined by treating physician; 18 to 80 years of age; GSV reflux with or without SFJ reflux on ultrasound; and C2 or C3 disease. Exclusion criteria were prior deep vein thrombosis; prior vein ablation on the index limb; ilio-caval obstruction; and renal, hepatic, or heart failure requiring prior hospitalization. An a priori sample size was calculated. We used multiple linear regression (adjusted for patient characteristics) to compare differences in VCSS scores of the two groups at baseline, and to test whether scores were equivalent using a priori equivalence boundaries of +1 and -1. In secondary analyses, we tested differences in VCSS scores in patients with C2 and C3 disease separately. RESULTS: A total of 352 patients were enrolled; 64.2% (n = 226) had SFJ reflux, and 35.8% (n = 126) did not. The two groups did not differ by major clinical characteristics. The mean age of the cohort was 53.9 ± 14.3 years; women comprised 74.2%; White patients 85.8%; and body mass index was 27.8 ± 6.1 kg/m2. The VCSS scores in patients with and without SFJ reflux were found to be equivalent; SFJ reflux was not a significant predictor of VCSS score; and mean VCSS scores did not differ significantly (6.4 vs 6.6, respectively, P = .40). In secondary subset analyses, VCSS scores were equivalent between C2 patients with and without SFJ reflux, and VCSS scores of C3 patients with SFJ reflux were lower than those without SFJ reflux. CONCLUSIONS: Symptom severity is equivalent in patients with GSV reflux with or without SFJ reflux. The absence of SFJ reflux alone should not determine the treatment paradigm in patients with symptomatic chronic venous insufficiency. Patients with GSV reflux who meet clinical criteria for treatment should have equivalent treatment regardless of whether or not they have SFJ reflux.

RESUMO

OBJECTIVE: The aim of this study was to compare the outcomes and complications of selected patients treated with endovenous laser ablation (EVLA) or ambulatory phlebectomy for foot varicose veins. METHODS: From October 2016 to February 2022, selected patients undergoing EVLA (using 1470-nm with radial-slim or bare-tip fibers) or phlebectomy of foot varicose veins for cosmetic indications were analyzed, and the outcomes were compared. Patients were classified according to the Clinical, Etiologic, Anatomical, and Pathophysiological (CEAP) classification. Anatomic criteria provided the basis for the decision to perform EVLA or phlebectomy. Clinical and ultrasound assessments were performed on postoperative days 7, 30, and 90 for visualization of the sapheno-femoral and sapheno-popliteal junctions and the deep venous system. Disease severity was graded with the Venous Clinical Severity Score (VCSS), and quality of life was measured with the Aberdeen Varicose Vein Questionnaire (AVVQ) before and after treatment. Treatment outcomes were evaluated based on changes in VCSS and AVVQ scores. The groups were also compared for procedure-related complications. Data were statistically analyzed in SPSS v. 20.0 using the χ2, Student t test, Mann-Whitney test, Wilcoxon test, and analysis of variance. The results were presented as mean (standard deviation or median (interquartile range). RESULTS: The study included 270 feet of 171 patients. Mean patient age was 52.3 (standard deviation, 13.1) years, ranging from 21 to 84 years; 133 (77.8%) were women. Of 270 feet, 113 (41.9%) were treated with EVLA and 157 (58.1%) with phlebectomy. The median preoperative CEAP class was 2 (interquartile range, 2-3) in the phlebectomy and EVLA groups, with no statistically significant difference between the groups (P = .507). Dysesthesia was the most common complication in both groups. Only transient induration was significantly different between EVLA (7.1%) and phlebectomy (0.0%) (P = .001). The two approaches had an equal impact on quality of life and disease severity. CONCLUSIONS: Treatment complications were similar in phlebectomy and EVLA and to those previously described in the literature.

RESUMO

BACKGROUND: Chronic venous insufficiency is a common medical condition that afflicts over 30 million adults in the United States. Treatment and management have changed dramatically over the past 20 years with the introduction of various endovenous therapies, including radiofrequency ablation (RFA) and cyanoacrylate closure using the Venaseal system. In this study, we explore a direct comparison of outcomes between RFA and VenaSeal conducted by a single surgeon within a managed care organization. METHODS: Between May 2020 and December 2021, there were 87 patients undergoing 97 total procedures who were treated with either VenaSeal (n = 55) or RFA (n = 42), conducted by a single surgeon within a managed care organization. Primary outcomes included successful greater saphenous vein (GSV) closure, postoperative deep vein thrombosis (DVT), embolization, saphenofemoral junction (SFJ) thrombosis, skin reaction (allergic or thrombophlebitis), or procedure-related emergency room (ER) and urgent care (UC) visits. Retrospective chart review was conducted to describe patient demographics, indications for treatment, treatment details (number of access sites and indication for treatment), as well as follow-up adjunctive vein procedures (sclerotherapy and stab phlebectomy). RESULTS: All patients had postprocedural ultrasound (US) performed within 7 days by the operating surgeon and mean overall patient follow-up from index procedure was 12 months; 2 patients were lost to follow-up due to death. All operations utilized intraoperative US, and SFJ thrombosis was not observed in any patient postprocedure. The average age of VenaSeal and RFA groups was 59.05 and 59.51 years, respectively. The average number of access sites during the procedure for VenaSeal and RFA was 1.56 and 1.20, respectively. Of the 55 VenaSeal treatments, 9.1% of patients reported postoperative skin reactions, and 9.1% of patients underwent subsequent stab phlebectomy (22 stabs on average). Of the 42 RFA treatments, 7.1% of RFA patients reported postoperative skin reactions, and 9.5% underwent subsequent stab phlebectomy (36 stabs on average). The percentage of patients who had postoperative UC or emergency department visits related to the procedure in the VenaSeal and RFA groups was 3.6% and 0%, respectively. CONCLUSIONS: Both VenaSeal and RFA demonstrated effective vein closure of the GSV at 12-month follow-up, with VenaSeal demonstrating continued noninferiority to RFA. Based on our data, postoperative skin reactions do not appear to be significantly higher with VenaSeal treatment, as previously reported.
