Abstract
Peripheral vascular diseases (PVDs) represent a significant burden on global human health and healthcare systems. With continued growth in obesity and diabetes, it is likely that the incidence of these conditions will increase. As many PVDs remain undiagnosed, low-cost and easy to use diagnostic methods are required. This work uses newly developed wearable electro-resistive morphic sensors to assess venous and arterial competence in the lower limbs of 36 healthy subjects. Comparison of this HeMo device was made to currently available benchtop light reflection rheography and photoplethymography devices. Results indicate that HeMo can detect the physiological signals of interest for both chronic venous insufficiency and peripheral arterial disease and all subjects were interpreted as healthy by each system. However, measurement repeatability of HeMo was highlighted as an issue that requires further system development. Furthermore, as HeMo captures changes in a section of limb circumference due to changes in underlying blood movement, rather than at a single point, the recorded signal is typically damped by comparison. This factor should be considered in any future developments.

Abstract
PURPOSE This study aims to investigate the safety and efficacy of a new device using microwave technology for the endovenous ablation of the great saphenous vein (GSV) causing symptomatic lower limb varicose veins (LLVV). MATERIALS AND METHODS This prospective, single-arm, single-center, cohort study investigated the safety and effectiveness of endovenous microwave ablation for the treatment of symptomatic LLVV. Enrollment period was set between January and December 2020. Primary safety endpoint was the occurrence of procedure-related complications and primary efficacy endpoint was anatomical success defined as the duplex ultrasound (DUS)-proven GSV occlusion at 1 year follow-up. Secondary endpoints included 1-year clinical success (CEAP classification improvement), repeat procedures rate due to GSV recanalization, and pain assessment at 24 h post treatment. RESULTS In total, 50 patients (42 female; mean age: 62 ± 12 years) with 64 limbs were treated. No procedure-related complications were noted. Technical success was 95.3% (61/64 GSVs), as three cases of GSV recanalization were detected. Clinical success was 100%, as in all cases symptoms improvement by at least one grade according to CEAP classification, was achieved. Mean CEAP grade significantly improved from 3.3 ± 0.72 (median: 3) at baseline to 1.8 ± 0.85 (median: 2) at 1-year (p < 0.0001). There were no repeat procedures due to GSC recanalization. The median 24-h VAS value was 2 (mean: 1.9 ± 1.4). CONCLUSIONS Endovenous microwave ablation was safe and effective for the treatment of varicose veins, achieving high 1-year GSV occlusion rates.

Thromboembolic outcomes are decreased with the use of a standardized venous thromboembolism risk assessment and prophylaxis protocol for patients undergoing superficial venous procedures. J Vasc Surg Venous Lymphat Disord 2023; 11:928-937.e1. [PMID: 37127256 DOI: 10.1016/j.jvsv.2023.04.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Revised: 04/11/2023] [Accepted: 04/21/2023] [Indexed: 05/03/2023]
Abstract
OBJECTIVE Patients with venous insufficiency can be treated with ablation or phlebectomy, or both. Patients undergoing superficial venous procedures have an elevated risk of deep vein thrombosis (DVT) and pulmonary embolism (PE). At our institution, we initiated a standardized protocol in which patients with a Caprini score (2005 version) of ≥8 are treated with 1 week of prophylactic anticoagulation after the procedure. Duplex ultrasound was performed at 1 week and then within 90 days after the procedure. This aim of the present study was to determine the thrombotic and clinical outcomes after superficial vein procedures using a standardized protocol for DVT/PE risk assessment and prophylaxis. METHODS We performed a retrospective analysis of prospectively collected data of superficial vein procedures from 2015 to 2021 at a single center. The patient demographics, CEAP (Clinical-Etiology-Anatomy-Pathophysiology) clinical class, venous clinical severity score, patient-reported outcomes, treatment type, Caprini scores, pre- and postoperative anticoagulation use, and outcomes were collected. Descriptive statistics were used for the patient demographics, procedure details, and unadjusted surgical outcomes. Multivariable logistic regression was used to evaluate the relationship between procedure type and DVT and PE after adjusting for patient characteristics, disease severity, periprocedural anticoagulation, and Caprini score. RESULTS A total of 1738 limbs were treated with ablation (n = 820), phlebectomy (n = 181), or ablation and phlebectomy (n = 737). More patients were women (67.1%) and White (90.9%). The overall incidence of DVT/PE was 1.4%. Patients undergoing ablation with phlebectomy had higher rates of DVT/PE (2.7%) than those undergoing ablation (0.2%) or phlebectomy alone (1.7%; P < .01). However, only 30% of DVTs were above the knee. On multivariate analysis, only the procedure type predicted for DVT/PE. However, patients undergoing ablation and phlebectomy achieved better patient-reported outcomes (Caprini score, 5.9) compared with those undergoing ablation (Caprini score, 7.2) or phlebectomy (Caprini score, 7.9) alone (P < .01). The best improvement in the venous clinical severity score was seen with phlebectomy alone. CONCLUSIONS The expected difference in the DVT/PE rates between high- and low-risk groups did not materialize in our patients, perhaps secondary to the additional chemoprophylaxis prescribed for the high-risk cohort (Caprini score, ≥8). These results call for a randomized trial to assess the efficacy of a standardized protocol in the reduction of DVT/PE after superficial vein procedures.

Abstract
BACKGROUND Venous leg ulcers (VLUs) are a serious manifestation of chronic venous disease affecting up to 3% of the adult population. This typically recalcitrant and recurring condition significantly impairs quality of life, and its treatment places a heavy financial burden upon healthcare systems. The longstanding mainstay treatment for VLUs is compression therapy. Surgical removal of incompetent veins reduces the risk of ulcer recurrence. However, open surgery is an unpopular option amongst people with VLU, and many people are unsuitable for it. The efficacy of the newer, minimally-invasive endovenous techniques has been established in uncomplicated superficial venous disease, and these techniques can also be used in the management of VLU. When used with compression, endovenous ablation aims to further reduce pressure in the veins of the leg, which may impact ulcer healing. OBJECTIVES To determine the effects of superficial endovenous ablation on the healing and recurrence of venous leg ulcers and the quality of life of people with venous ulcer disease. SEARCH METHODS In April 2022 we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE (including In-Process & Other Non-Indexed Citations); Ovid Embase and EBSCO CINAHL Plus. We also searched clinical trials registries for ongoing and unpublished studies, and scrutinised reference lists of relevant included studies as well as reviews, meta-analyses and health technology reports to identify additional studies. There were no restrictions on the language of publication, but there was a restriction on publication year from 1998 to April 2022 as superficial endovenous ablation is a comparatively new technology. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing endovenous ablative techniques with compression versus compression therapy alone for the treatment of VLU were eligible for inclusion. Studies needed to have assessed at least one of the following primary review outcomes related to objective measures of ulcer healing such as: proportion of ulcers healed at a given time point; time to complete healing; change in ulcer size; proportion of ulcers recurring over a given time period or at a specific point; or ulcer-free days. Secondary outcomes of interest were patient-reported quality of life, economic data and adverse events. DATA COLLECTION AND ANALYSIS Two reviewers independently assessed studies for eligibility, extracted data, carried out risk of bias assessment using the Cochrane RoB 1 tool, and assessed GRADE certainty of evidence. MAIN RESULTS The previous version of this review found no RCTs meeting the inclusion criteria. In this update, we identified two eligible RCTs and included them in a meta-analysis. There was a total of 506 participants with an active VLU, with mean durations of 3.1 months ± 1.1 months in the EVRA trial and 60.5 months ± 96.4 months in the VUERT trial. Both trials randomised participants to endovenous treatment and compression or compression alone, however the compression alone group in the EVRA trial received deferred endovenous treatment (after ulcer healing or from six months). There is high-certainty evidence that combined endovenous ablation and compression compared with compression therapy alone, or compression with deferred endovenous treatment, improves time to complete ulcer healing (pooled hazard ratio (HR) 1.41, 95% CI 1.36 to 1.47; I2 = 0%; 2 studies, 466 participants). There is moderate-certainty evidence that the proportion of ulcers healed at 90 days is probably higher with combined endovenous ablation and compression compared with compression therapy alone or compression with deferred endovenous treatment (risk ratio (RR) 1.14, 95% CI 1.00 to 1.30; I2 = 0%; 2 studies, 466 participants). There is low-certainty evidence showing an unclear effect on ulcer recurrence at one year in people with healed ulcers with combined endovenous treatment and compression when compared with compression alone or compression with deferred endovenous treatment (RR 0.29, 95% CI 0.03 to 2.48; I2 = 78%; 2 studies, 460 participants). There is also low-certainty evidence that the median number of ulcer-free days at one year may not differ (306 (interquartile range (IQR) 240 to 328) days versus 278 (IQR 175 to 324) days) following combined endovenous treatment and compression when compared with compression and deferred endovenous treatment; (1 study, 450 participants). There is low-certainty evidence of an unclear effect in rates of thromboembolism between groups (RR 2.02, 95% CI 0.51 to 7.97; I2 = 78%, 2 studies, 506 participants). The addition of endovenous ablation to compression is probably cost-effective at one year (99% probability at GBP 20,000/QALY; 1 study; moderate-certainty evidence). AUTHORS' CONCLUSIONS Endovenous ablation of superficial venous incompetence in combination with compression improves leg ulcer healing when compared with compression alone. This conclusion is based on high-certainty evidence. There is moderate-certainty evidence to suggest that it is probably cost-effective at one year and low certainty evidence of unclear effects on recurrence and complications. Further research is needed to explore the additional benefit of endovenous ablation in ulcers of greater than six months duration and the optimal modality of endovenous ablation.

[PMID: 35934305 DOI: 10.1016/j.jvsv.2022.06.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Revised: 05/24/2022] [Accepted: 06/02/2022] [Indexed: 11/20/2022]
Abstract
OBJECTIVE The primary aim of this observational study was to measure the Revised Venous Clinical Severity Score (rVCSS) in patients treated for varicose veins (VVs) owing to saphenous vein reflux. Treatment was by endovenous thermal ablation (ETA) alone or by ETA and ambulatory phlebectomy (AP). A secondary aim was to determine whether participant characteristics and treatment methods affect rVCSS and how the score changes over time. METHODS We enrolled 44 men with 55 treated legs and 79 women with 105 treated legs (bilateral cases, 23.1%). Patients were treated and evaluated from April 2016 to September 2020. All legs were treated by ETA, and participants were divided into three groups depending on AP treatment: E0 group (40 legs), no AP; EP1 group (101 legs), AP performed only at one site above or below the knee; and EP2 group (19 legs), AP performed both above and below the knee. The rVCSS was measured in the treated legs up to five times: preoperatively and on postoperative days (POD) 1, 7, 90, and 180. RESULTS The mean age was 67.5 ± 11.24 years (range, 32-87 years). No significant differences in medical history or demographics or lifestyle were found between the groups. The mean preoperative rVCSS also was not different between groups (E0, 4.4 ± 0.3 points; EP1, 4.6 ± 0.2 points; and EP2, 5.4 ± 0.4 points; P = .14). Factors associated with less improvement in the rVCSS were a high body mass index (P = .046) and the occurrence of endovenous heat-induced thrombosis (P = .001), and factors associated with more improvement in the rVCSS were hypertension (P = .026), hyperuricemia (P = .022), and wearing compression stockings (P = .013). The rVCSS decreased strongly at POD1 and then gradually decreased until POD180. It was not significantly different between EP1 and EP2, but it improved significantly earlier in these two groups than in the E0 group. The rVCSS at POD180 was as follows: E0, 1.633 ± 0.233 points; EP1, 1.003 ± 0.148 points; and EP2, 0.982 ± 0.322 points. CONCLUSIONS Factors associated with less improvement in the rVCSS are a high body mass index and the occurrence of endovenous heat-induced thrombosis. Hypertension, hyperuricemia, and wearing compression stockings are associated with greater improvements in the rVCSS. Patients treated with ETA and AP tend to improve earlier than patients treated by ETA alone, but all patients improve to nearly the same level within 6 months.

Abstract
OBJECTIVE Endothermal ablation is well established for the treatment of the great and small saphenous veins. Data are lacking for treatment of the Anterior Accessory Saphenous Vein (AASV). The purpose of this study is to evaluate the safety and efficacy of AASV treatment using endothermal ablation. METHODS This was a retrospective review of 314 limbs at a single academic institution from 2016-2018 using the institutional Vascular Quality Initiative database. All limbs had documented AASV reflux. Baseline characteristics were evaluated including age, sex, ethnicity, CEAP (clinical, etiology, anatomy, pathophysiology) classification, Venous Clinical Severity Score (VCSS), and vein diameter. Outcomes relating to procedure safety and efficacy included treatment modality and length, successful ablation on post-operative imaging, post-procedural clinical outcomes, incidence of endothermal heat induced thrombosis (EHIT), and any post-procedural complication. RESULTS A total of 314 consecutive limbs were identified from 2016-2018. Pre-procedure VCSS scores were available for 312 limbs and averaged 6.13 ± 3.33. History of varicose veins were reported in all limbs with 49.4% (n=155) having previously undergone a procedure. The most common presenting symptom was mild edema in 52.5% (n=165). Vein diameter and assessment of reflux were obtained by venous duplex ultrasound (DUS). The largest AASV diameter was available for 304 limbs, averaging 7.93 ± 2.69 mm. Treatment modalities included radiofrequency ablation (RFA) in 59.2% (n=186), endovenous laser ablation (EVLA) in 37.9% (n=119), and isolated microphlebectomy in 2.9% (n=9). 38.5% (N=121) of limbs underwent concomitant microphlebectomy at the time of EVLA. Total treatment length was obtained in 297 limbs, averaging 23.0 cm ± 12.0. Post-operatively, 94.6% (n=297) of limbs were prescribed compression stockings. Post-operative DUS was performed in 312 limbs, revealing successful ablation in 96.5% (n=303) with 2 limbs (0.6%) developing an EHIT, both treated with therapeutic enoxaparin for one week. Repeat DUS revealed thrombus resolution in one limb, while the other patient was lost to follow-up. VCSS scores post-procedure were available for 145 limbs and averaged 4.45 ± 2.31. This was a statistically significant decrease from pre-procedure VCSS scores (p<0.01). Average duration of follow-up was 2.2 years, with two limbs lost to follow-up. Of the 9 limbs (3.5%) whose initial procedure failed, 5 (56%) were treated using RFA and 4 (44%) were treated using EVLA. There were no other post-operative complications. CONCLUSION Our experience over a three-year period for treating the AASV shows it to be safe and effective in a broad range of disease severity with an improvement in VCSS and a low incidence of EHIT. Additionally, RFA and EVLA exhibit similar treatment efficacy. Long-term follow-up data are needed.

Abstract
While endovenous thermal ablation (ETA) become first choice of treatment for varicose veins, overuse of ETA for the inappropriate indication is growing problem. ETA is performed not only on varicose cases without symptom but also non diseased cases with segmental reflux of saphenous veins or no reflux. Indications of ETA was demonstrated in “the Clinical Practice Guidelines for ETA for Varicose Veins 2019” by Japanese Society of Phlebology. Purpose of this supplement is description of basics of correct indication for ETA. We also demonstrate the typical case of overuse of ETA for wrong indication.

Abstract
A previously published review focused on generic and disease-specific patient-reported outcome measures (PROMs) relevant to vascular surgery but limited to arterial conditions. The objective of this project was to identify all available PROMs relevant to diseases treated by vascular surgeons and to evaluate vascular surgeon perceptions, barriers to widespread implementation, and concerns regarding PROMs. We provide an overview of what a PROM is and how they are developed, and summarize currently available PROMs specific to vascular surgeons. We also report results from a survey of 78 Society for Vascular Surgery members serving on committees within the Policy and Advocacy Council addressing the barriers and facilitators to using PROMs in clinical practice. Finally, we report the qualitative results of two focus groups conducted to assess granular perceptions of PROMS and preparedness of vascular surgeons for widespread implementation of PROMs. These focus groups identified a lack of awareness of existing PROMs, knowledge of how PROMs are developed and validated, and clarity around how PROMs should be used by the clinician as main subthemes for barriers to PROM implementation in clinical practice.

Abstract
BACKGROUND Great saphenous vein (GSV) incompetence, causing varicose veins and venous insufficiency, makes up the majority of lower-limb superficial venous diseases. Treatment options for GSV incompetence include surgery (also known as high ligation and stripping), laser and radiofrequency ablation, and ultrasound-guided foam sclerotherapy. Newer treatments include cyanoacrylate glue, mechanochemical ablation, and endovenous steam ablation. These techniques avoid the need for a general anaesthetic, and may result in fewer complications and improved quality of life (QoL). These treatments should be compared to inform decisions on treatment for varicosities in the GSV. This is an update of a Cochrane Review first published in 2011. OBJECTIVES To assess the effects of endovenous laser ablation (EVLA), radiofrequency ablation (RFA), endovenous steam ablation (EVSA), ultrasound-guided foam sclerotherapy (UGFS), cyanoacrylate glue, mechanochemical ablation (MOCA) and high ligation and stripping (HL/S) for the treatment of varicosities of the great saphenous vein (GSV). SEARCH METHODS The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase, CINAHL, and AMED databases, and World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials registers to 2 November 2020. We undertook reference checking to identify additional studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) treating participants for varicosities of the GSV using EVLA, RFA, EVSA, UGFS, cyanoacrylate glue, MOCA or HL/S. Key outcomes of interest are technical success, recurrence, complications and QoL. DATA COLLECTION AND ANALYSIS Two review authors independently selected trials, applied Cochrane's risk of bias tool, and extracted data. We calculated odds ratios (ORs) with 95% confidence intervals (CIs) and assessed the certainty of evidence using GRADE. MAIN RESULTS We identified 11 new RCTs for this update. Therefore, we included 24 RCTs with 5135 participants. Duration of follow-up ranged from five weeks to eight years. Five comparisons included single trials. For comparisons with more than one trial, we could only pool data for 'technical success' and 'recurrence' due to heterogeneity in outcome definitions and time points reported. All trials had some risk of bias concerns. Here we report the clinically most relevant comparisons. EVLA versus RFA Technical success was comparable up to five years (OR 0.98, 95% CI 0.41 to 2.38; 5 studies, 780 participants; moderate-certainty evidence); over five years, there was no evidence of a difference (OR 0.85, 95% CI 0.30 to 2.41; 1 study, 291 participants; low-certainty evidence). One study reported recurrence, showing no clear difference at three years (OR 1.53, 95% CI 0.78 to 2.99; 291 participants; low-certainty evidence), but a benefit for RFA may be seen at five years (OR 2.77, 95% CI 1.52 to 5.06; 291 participants; low-certainty evidence). EVLA versus UGFS Technical success may be better in EVLA participants up to five years (OR 6.13, 95% CI 0.98 to 38.27; 3 studies, 588 participants; low-certainty evidence), and over five years (OR 6.47, 95% CI 2.60 to 16.10; 3 studies, 534 participants; low-certainty evidence). There was no clear difference in recurrence up to three years and at five years (OR 0.68, 95% CI 0.20 to 2.36; 2 studies, 443 participants; and OR 1.08, 95% CI 0.40 to 2.87; 2 studies, 418 participants; very low-certainty evidence, respectively). EVLA versus HL/S Technical success may be better in EVLA participants up to five years (OR 2.31, 95% CI 1.27 to 4.23; 6 studies, 1051 participants; low-certainty evidence). No clear difference in technical success was seen at five years and beyond (OR 0.93, 95% CI 0.57 to 1.50; 5 studies, 874 participants; low-certainty evidence). Recurrence was comparable within three years and at 5 years (OR 0.78, 95% CI 0.47 to 1.29; 7 studies, 1459 participants; and OR 1.09, 95% CI 0.68 to 1.76; 7 studies, 1267 participants; moderate-certainty evidence, respectively). RFA versus MOCA There was no clear difference in technical success (OR 1.76, 95% CI 0.06 to 54.15; 3 studies, 435 participants; low-certainty evidence), or recurrence (OR 1.00, 95% CI 0.21 to 4.81; 3 studies, 389 participants; low-certainty evidence). Long-term data are not available. RFA versus HL/S No clear difference in technical success was detected up to five years (OR 5.71, 95% CI 0.64 to 50.81; 2 studies, 318 participants; low-certainty evidence); over five years, there was no evidence of a difference (OR 0.88, 95% CI 0.29 to 2.69; 1 study, 289 participants; low-certainty evidence). No clear difference in recurrence was detected up to three years (OR 0.93, 95% CI 0.58 to 1.51; 4 studies, 546 participants; moderate-certainty evidence); but a possible long-term benefit for RFA was seen (OR 0.41, 95% CI 0.22 to 0.75; 1 study, 289 participants; low-certainty evidence). UGFS versus HL/S Meta-analysis showed a possible benefit for HL/S compared with UGFS in technical success up to five years (OR 0.32, 95% CI 0.11 to 0.94; 4 studies, 954 participants; low-certainty evidence), and over five years (OR 0.09, 95% CI 0.03 to 0.30; 3 studies, 525 participants; moderate-certainty evidence). No clear difference was detected in recurrence up to three years (OR 1.81, 95% CI 0.87 to 3.77; 3 studies, 822 participants; low-certainty evidence), and after five years (OR 1.24, 95% CI 0.57 to 2.71; 3 studies, 639 participants; low-certainty evidence). Complications were generally low for all interventions, but due to different definitions and time points, we were unable to draw conclusions (very-low certainty evidence). Similarly, most studies evaluated QoL but used different questionnaires at variable time points. Rates of QoL improvement were comparable between interventions at follow-up (moderate-certainty evidence). AUTHORS' CONCLUSIONS Our conclusions are limited due to the relatively small number of studies for each comparison and differences in outcome definitions and time points reported. Technical success was comparable between most modalities. EVLA may offer improved technical success compared to UGFS or HL/S. HL/S may have improved technical success compared to UGFS. No evidence of a difference was detected in recurrence, except for a possible long-term benefit for RFA compared to EVLA or HL/S. Studies which provide more evidence on the breadth of treatments are needed. Future trials should seek to standardise clinical terminology of outcome measures and the time points at which they are measured.

Abstract
BACKGROUND The endovascular technique of mechanochemical ablation (MOCA) has become popular in treating patients with saphenous reflux. We reported the histopathological findings in human ex-vivo incompetent great saphenous veins following treatment with saline, polidocanol, mechanical ablation and MOCA using ClariVein device. METHODS Twenty-four vein GSV specimens were obtained via traditional surgery and treated with four methods: Group A: 0.9% normal saline (NS); Group B: 3% polidocanol; Group C: mechanical ablation + 0.9% NS; Group D: mechanical ablation + 3% polidocanol (MOCA). Hematoxylin and eosin (HE), Masson's trichrome and immunohistochemical staining were performed on each specimen and integrated optical densities were measured with vWF and a-SMA stains and statistically evaluated. vWF staining was used to assess endothelial damage and a a-SMA staining was used to assess media injury. RESULTS HE and Masson's trichrome staining of Groups C and D revealed severe damage to the endothelium and media compared to Groups A and B. The statistical result of vWF staining showed the damage of endothelium was significantly increased by Group D compared to Groups A, B and C. The statistical result of a-SMA staining showed the damage of media was significantly increased by Groups C and D compared to Groups A and B. CONCLUSIONS The mechanism of MOCA was caused by both endothelium damage and media tearing. The damage of endothelium was significantly increased by MOCA when compared with mechanical ablation alone.

Efficiency of Prophylactic Ablation of the Tributary Venous Pathways Draining Around the Saphenofemoral Junction to Decrease the Rate of Future Varicose Vein and Symptoms Occurence. Ann Vasc Surg 2021; 75:267-274. [PMID: 33823264 DOI: 10.1016/j.avsg.2021.02.047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2020] [Revised: 02/11/2021] [Accepted: 02/13/2021] [Indexed: 11/30/2022]
Abstract
BACKGROUND There are various other collaterals draining into the venous system around the saphenofemoral junction in addition to the great saphenous vein. We aimed to determine the efficiency of prophylactic ablation of tributary veins in long term varicose vein and symptom recurrence. METHODS Two hundred and sixty-three consecutive patients whom underwent radiofrequency ablation therapy for the treatment of superficial venous reflux disease were investigated. There were 129 patients who received isolated great saphenous vein ablation (Group A) where as 134 patients underwent ablation of the other tributary veins in addition to the great saphenous vein (Group B) between June 2015 and January 2017. The tributary superficial veins; refluxing and/or not refluxing, draining into the saphenofemoral junction were selectively catheterized and ablated in Group B. Patients are followed at least 1 year after the procedures regulary and researched for recurrence of varciose veins and symptoms. RESULTS Gender, mean age, body mass index, diameter of the great saphenous veins, small saphenous vein disease, and grade of deep venous insufficiency did not differ significantly between the two groups. The mean number of tributary veins were similar in both groups (n: 1.9 ± 0.4 in Group A vs. n: 1.8 ± 0.7 in Group B) which were detected preoperatively as well as during the procedure. The mean number of ablated tributary venous pathways could be 1.4 ± 0.6 in Group B. During the follow up period symptoms related with varicose veins recurred in 19 patients in Group A where as in 7 patients in Group B (P < 0.05). Three of these symptomatic patients in Group B were the ones in whom the tributary pathways could not be catheterized ablated where as 14 patients in Group A were diagnosed with newly refluxing tributary pathways. All the symptomatic patients in both groups were managed medically and/or with additional interventions. CONCLUSION The absence of any fascial unsheathing and the parietal weakness are suggestive of a lower resistance of the tributary veins wall, so collapse and size of veins make it more complex to catheterization regarding to great saphenous vein. Ablation of the tributary superficial venous pathways during the treatment of great saphenous vein reflux disease decreased the rate of recurrence of superficial venous reflux disease and patients symtoms in our modest cohort.

Abstract
Introduction: Chronic venous insufficiency (CVI) is a chronic condition, triggered by reflux through the saphenous vein network. Aim: To determine the efficacy of endovenous laser ablation (LA) and radiofrequency ablation (RFA) for CVI treatment in the lower extremities, at the Bach Mai Radiology Center. Methods: This retrospective study was approved by the institutional review board of Bach Mai Hospital. The study recruited 49 people, from August 2016 to April 2018, with recurrent venous insufficiency in the lower extremities and measured 56 ablated veins. Results: In this study, 8 patients (10 veins, with a mean diameter of 5.83 ± 0.96 mm) were treated with RFA, and 41 patients (46 veins, with a mean diameter of 7.96 ± 3.47 mm) were treated with LA. The occlusion rates for LA- and RFA-treated veins were very effective, at 95.7% and 90%, respectively. No significant differences in occlusion rates or clinical improvements were observed between the two ablation methods. On the first day post-treatment, the visual analog score (VAS) value for the LA group was significantly higher than that for the RFA group. Furthermore, ecchymosis, 1 day after treatment, and hyperpigmentation, paresthesia, and numbness, 1 month after treatment, were only observed in the LA group. Conclusion: Both LA and RFA were minimally-invasive and safe therapies. No serious complications requiring further interventions were reported and the treatment effectively improved the clinical symptoms of patients. Based on our study, we recommend that RFA should be considered for moderate dilated saphenous vein cases, whereas LA should be indicated for large dilated saphenous vein cases, with or without aneurysm.

Abstract
OBJECTIVE Endothermal techniques have proved to be effective for treatment of incompetent truncal veins. The tumescentless mechanochemical ablation (MOCA) technique has become an alternative treatment modality, but its outcome with regard to endothermal techniques is still unclear. METHODS A multicenter prospective randomized controlled trial was designed comparing MOCA with radiofrequency ablation (RFA) to treat great saphenous vein incompetence with the hypothesis that MOCA is associated with less postprocedural pain and a comparable anatomic and clinical success rate at 1-year follow-up. Disease-specific quality of life and general health-related quality of life (HRQoL) were measured using questionnaires. Inclusion was terminated prematurely because reimbursement was suspended. RESULTS A total of 213 patients (46.3% of intended number of patients) were randomized, of whom 209 were treated (105 in the MOCA group and 104 in the RFA group). Overall median pain scores during the first 14 days were lower after MOCA (0.2 vs 0.5 after RFA; P = .010), although the absolute difference was small. At 30 days, similar complication numbers (MOCA, n = 62; RFA, n = 63) and HRQoL scores (Aberdeen Varicose Vein Questionnaire: MOCA, 8.9; RFA, 7.6; P = .233) were observed. Hyperpigmentation was reported in seven patients in the MOCA group and two patients in the RFA group (P = .038). In the MOCA group, there were four complete failures (3.8%) compared with none in the RFA group (P = .045), although in one patient at 1 year, the vein showed occlusion. Median 30-day Venous Clinical Severity Score (VCSS) was significantly lower at 30 days after MOCA (1.0 vs 2.0 in the RFA group; P = .001), whereas VCSS was comparable at baseline (MOCA, 4.0; RFA, 5.0; P = .155). The 1- and 2-year anatomic success rate was lower after MOCA (83.5% and 80.0%) compared with RFA (94.2% and 88.3%; P = .025 and .066), mainly driven by partial recanalizations. After 2 years of follow-up, no differences were observed in the number of complete failures. Similar clinical success rates at 1 year (MOCA, 88.7%; RFA, 93.2%; P = .315) and 2 years (MOCA, 93.0%; RFA, 90.4%; P = .699) and no differences in HRQoL scores on the Aberdeen Varicose Vein Questionnaire at 1 year (MOCA, 7.5; RFA, 7.0; P = .753) and 2 years (MOCA, 5.0%; RFA, 4.8%; P = .573) were observed. There were two cardiac serious adverse events, a ventricular fibrillation in the MOCA group (1 year) and an unstable angina in the RFA group (2 years). One deep venous thrombosis occurred in the RFA group on 1-year duplex ultrasound, without clinical sequelae. CONCLUSIONS Unilateral treatment with MOCA in the short term resulted in less postoperative pain but more hyperpigmentation compared with RFA and a faster improvement in VCSS. More anatomic failures were reported after MOCA, mostly driven by partial recanalizations, but both techniques were associated with similar clinical outcomes at 1 year and 2 years.

Abstract
BACKGROUND Stimulated by published reports of potentially inappropriate application of venous procedures, the American Venous Forum and its Ethics Task Force in collaboration with multiple other professional societies including the Society for Vascular Surgery (SVS), American Vein and Lymphatic Society (AVLS), and the Society of Interventional Radiology (SIR) developed the appropriate use criteria (AUC) for chronic lower extremity venous disease to provide clarity to the application of venous procedures, duplex ultrasound imaging, timing, and reimbursements. METHODS The AUC were developed using the RAND/UCLA Appropriateness Method, a validated method of developing appropriateness criteria in health care. By conducting a modified Delphi exercise and incorporating best available evidence and expert opinion, AUC were developed and scored. RESULTS There were 119 scenarios rated on a scale of 1 to 9 by an expert panel, with 1 being never appropriate and 9 being appropriate. The majority of scenarios consisted of symptomatic indications were deemed appropriate for venous intervention. For scenarios with anatomically short segments of reflux and/or no symptoms, the indications were rated less appropriate. For the indication of edema, a wide dispersion of ratings was observed especially for short segments of saphenous reflux or stenting for iliac/ inferior vena cava disease, noting that there are multifactorial causes of edema, some of which could coexist with venous disease and possibly impact effectiveness of treatment. Several scenarios were considered never appropriate, including treatment of saphenous veins with no reflux, iliac vein or inferior vena cava stenting for iliac vein compression as an incidental finding by imaging with minimal or no symptoms or signs, and incentivizing sonographers to find reflux. CONCLUSIONS The AUC statements are intended to serve as a guide to patient care, particularly in areas where high-quality evidence is lacking to aid clinicians in making day-to-day decisions for common venous interventions. This may also prove useful when applied on a population level, such as practice patterns, and not necessarily to dictate decision making for individual cases. As a product of a collaborative effort, it is hoped that this could be utilized by physicians and multiple stakeholders committed toward improving patient care and to identify and stimulate future research priorities.

Abstract
BACKGROUND The rates of thromboembolic complications such as deep vein thrombosis (DVT) after venous ablation procedures for symptomatic superficial venous insufficiency are controversial. We sought to describe the risk factors for and incidence of DVT after radiofrequency ablation (RFA) and laser ablation (LA). METHODS We queried the Truven Health Marketscan Database from 2007-16 for patients who underwent RFA or LA and had a follow-up duplex ultrasound within 30 days of the ablation procedure. The primary outcome was DVT at 7 and 30 days identified by International Classification of Diseases-9 and International Classification of Diseases-10 codes. Multivariable regression was used to evaluate the patient and procedural variables associated with a DVT at 30 days, expressed as odds ratios (ORs) with a 95% confidence interval (95% CI). Patients and procedures with a previous DVT diagnosis were excluded. RESULTS A total of 256,999 patients underwent 433,286 ablation procedures: 192,195 (44.4%) RFA and 241,091 LA. Of these, 8,203 (1.9%) had a newly diagnosed DVT within 7 days and 13,347 (3.1%) within 30 days of the procedure. The incidence of DVT decreased over the study period. LA (2.8%) demonstrated a lower incidence of DVT at 30 days compared with RFA (3.4%), P < 0.001. On multivariable regression, LA (OR, 0.82; 95% CI 0.80-0.85) was again associated with a decreased risk for 30-day DVT, as was female gender (OR, 0.74; 95% CI, 0.71-0.77), and sclerotherapy performed on the same day (OR, 0.91; 95% CI, 0.85-0.98). A diagnosis of peripheral artery disease (OR, 1.23; 95% CI, 1.16-1.31) and concomitant stab phlebectomy (OR, 1.43; 95% CI, 1.37-1.49) was associated with an increased risk of DVT within 30 days. CONCLUSIONS The incidence of newly diagnosed DVT within 30 days of an ablation procedure was 3.2%. The risk for DVT decreased in recent years, and LA was associated with an 18% decreased risk compared with RFA.

INTRODUCTION Open surgical ligation and stripping of the great saphenous vein is a highly cost-effective treatment when compared with conservative management and foam sclerotherapy but has limitations including post-operative morbidity and pain. This study aims to identify if the addition of tumescent anaesthesia could improve patient outcomes following treatment. METHODS Patients with primary superficial venous incompetence undergoing open surgical ligation and stripping of the great saphenous vein were randomised to either General Anaesthesia (GA) alone (GA) procedure or the addition of tumescent (G + T). The primary outcome was bodily pain (within SF-36) at one week. Additional outcomes included post-procedural pain score (100 mm visual analogue scale), complications and quality of life. RESULTS A total of 90 patients were randomised for inclusion. There was no significant difference in primary outcome; bodily pain at one week. Secondary outcome of 4-h post-procedural scores were significantly lower in the G + T group (32 (20-54) mm vs. (GA alone) 56 (24-70) mm (P = 0.016)). Complications were minor and equivalent. Both groups saw a significant increase (worsening) in Aberdeen Varicose Vein Questionnaire scores at week 1 with the G + T group faring worse at six weeks (10.0 (Interquartile Range [IQR] 5.6-17.9) vs. 4.3 (IQR 2.7-7.9) P = 0.004). CONCLUSION The G + T group did not demonstrate a significant difference in the one-week bodily pain domain. The addition of tumescent anaesthesia does improve immediate post-operative pain but appears to negatively impact on six-week quality of life. EudraCT Number: 2011-005574-39.

Abstract
Dermatologists encounter patients with a variety of lower extremity ulcers including those related to venous insufficiency and peripheral arterial disease. Vascular studies, including ankle brachial pressure index, toe pressure, toe brachial index, Doppler arterial waveform, Duplex ultrasonography, and angiography, play an essential role in the prevention, diagnosis, and management of vascular diseases. In fact, dermatologists are often the first medical providers to see patients with complex vascular conditions. Knowledge of the appropriate indications, interpretations, limitations, and advantages of the various vascular studies is critical to the successful and swift management of each patient presenting with a lower extremity ulcer. This study reviews the most commonly ordered arterial and venous studies and discusses the appropriate indications and interpretation of these studies.

Abstract
Introduction Endovenous mechanochemical ablation (MOCA) is an increasingly popular non-thermal non-tumescent technique used to treat axial reflux in patients with superficial venous incompetence. However, the optimal management of varicose tributaries following this technique is unknown and may impact on patient outcomes. This study compares MOCA with concomitant phlebectomy (MOCAP) versus ablation with sequential phlebectomy if required (MOCAS). Methods Patients with symptomatic Comprehensive Classification System for Chronic Venous Disorders (CEAP C2–C6) unilateral axial reflux were studied. Patient choice determined whether concomitant treatment of varicosities was carried out. The primary outcome was the Aberdeen Varicose Veins Questionnaire (AVVQ) at one year. Secondary outcomes included: Venous Clinical Severity Scores (VCSS), EuroQol 5-Domain quality of life scores, complications, procedure duration, procedural and post-operative pain scores and need for secondary procedures. Outcomes were assessed at baseline and then one week, six weeks, six months and one year post intervention. Results Fifty patients underwent MOCAP and 33 patients MOCAS. The two groups were comparable at baseline. MOCAP was associated with lower (better) AVVQ scores at six weeks (3.4 (0.5–6.0) vs. 6.1 (1.8–12.1); P = 0.009) and at six months (1.6 (0.0–4.5) vs. 3.34 (1.8–8.4); P = 0.009) but by one year the difference was no longer statistically significant (1.81 (0.0–4.5) vs. 3.81 (0.2–5.3); P = 0.099). MOCAP was associated with longer procedural duration (45 min (36–56) vs. 30 min (25–37); P < 0.001) and higher maximal periprocedural pain (31 (21–59) vs. 18 (7–25); P = 0.001). VCSS at all time points were lower in favour of MOCAP (0 (0–1) vs. 1 (0–3); P < 0.001). MOCAP was associated with fewer episodes of clinically significant thrombophlebitis (6 of 50 (12%) vs. 10 of 33 (30%); P = 0.039) and lower numbers of secondary procedures (2 (4%) vs. 6 (18%); P = 0.032). Conclusion Concomitant treatment of tributary varicosities following MOCA improves quality of life and clinical severity, while reducing rates of re-intervention and post-operative thrombophlebitis compared to sequential treatment. The penalty is a modest increase in procedural duration and discomfort. Further evidence from longer-term follow-up is needed.

Long-term outcomes of endovenous laser ablation and conventional surgery for great saphenous varicose veins. Br J Surg 2018; 105:1759-1767. [PMID: 30132797 DOI: 10.1002/bjs.10961] [Citation(s) in RCA: 47] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2018] [Revised: 05/29/2018] [Accepted: 06/26/2018] [Indexed: 01/14/2023]
Abstract
BACKGROUND Clinical guidelines recommend endovenous laser ablation (EVLA) over surgery based on short-term evidence, yet there are few studies reporting mid- to long-term outcomes. The aim of this study was to report the 5-year outcomes from an RCT of surgery versus EVLA for treatment of symptomatic great saphenous varicose veins. METHODS Patients with symptomatic varicose veins due to great saphenous vein (GSV) incompetence were followed up 5 years after enrolment in a randomized trial of either surgery (saphenofemoral junction ligation, GSV strip to the knee and multiple avulsions of varicosities) or EVLA plus multiple avulsions. Outcomes included: clinical recurrence, defined as new varicose veins greater than 3 mm in diameter; Venous Clinical Severity Score (VCSS); quality of life measured by means of Short Form 36, EuroQol Five Dimensions (EQ-5D™) and Aberdeen Varicose Vein Questionnaire (AVVQ); patient satisfaction; and duplex ultrasound examination (DUS) findings. RESULTS Some 218 of the 276 patients enrolled in the trial (79·0 per cent) were available for follow-up. Clinical recurrence was more frequent following surgery than EVLA at 5 years (34·3 versus 20·9 per cent; P = 0·010). Both groups demonstrated sustained significant improvements at 5 years over baseline in VCSS (surgery: median (i.q.r.) 1 (0-2) from 4 (3-5), P < 0·001; EVLA: 0 (0-1) from 4 (3-5), P < 0·001), AVVQ (surgery: 4·59 (0·56-9·78) from 13·69 (9·81-18·11), P < 0·001; EVLA: 3·35 (0·17 to 6·55) from 12·73 (9·41-17·32), P < 0·001) and EQ-5D™ (surgery: 1·000 (0·796-1·000) from 0·859 (0·796-1·000), P = 0·002; EVLA: 1·000 (0·796-1·000) from 0·808 (0·796-1·000), P = 0·002). VCSS was better for EVLA than surgery at 5 years (P = 0·031). Technical success assessed by DUS remained high at 5 years (85·4 per cent for surgery and 93·2 per cent for EVLA; P = 0·074). DUS-detected anatomical patterns of recurrence differed between the groups. CONCLUSION EVLA was more effective than surgery in preventing clinical recurrence 5 years after treatment of great saphenous varicose veins. Patient-reported outcome measures were similar. Registration number: NCT00759434 (http://www.clinicaltrials.gov).

Abstract
OBJECTIVE The objective of this study was to characterize the technique and to report the results of double prepuncture used during complex radiofrequency ablation (RFA) in cases of treating multiple incompetent veins or encountering focal obstruction to catheter advancement. METHODS A double prepuncture technique was applied in patients requiring endovascular ablation of multiple veins and patients with great saphenous vein cannulation failure. We treated 13 limbs in 12 patients during a 24-month period with RFA in which the double prepuncture technique was used. Clinical history, operative reports, outcomes, and follow-up were reviewed. RESULTS RFA was performed with the double puncture technique on, collectively, 10 great saphenous veins, 5 small saphenous veins, and 5 anterior accessory saphenous veins. Mean preoperative Clinical, Etiology, Anatomy, and Pathophysiology score was 4.38 ± 1.6. Three limbs required prepuncture because of difficulty in advancing the catheter cephalad through tortuosity and focal obstruction after failure with techniques such as a guidewire, a guide catheter, and manual compression with ultrasound guidance. Ten limbs received planned double prepuncture for multiple adjacent incompetent veins, for which venipuncture and cannulation of the second target vein would be difficult after tumescent application to the first vein. Postoperative ultrasound demonstrated successful closure of all target veins in which the double prepuncture technique was used. One patient had a deep venous thrombosis (7.7%) that resolved without complications. CONCLUSIONS Double prepuncture is a useful technical adjunct both for simultaneous endovenous ablation of multiple adjacent incompetent veins and when catheter passage is impeded. This technique aids in efficient and successful application of endovenous ablation to complex venous anatomy.

Abstract
BACKGROUND Treating great and small saphenous vein trunk insufficiency with cyanoacrylate glue is the least taxing treatment method of all available techniques. Due to long-term unavailability of commercial kits with n-butyl-2-cyanoacrylate (histoacryl) in the Czech Republic, we used a modified technique. PATIENTS AND METHODS Fifty-six limbs in 49 patients suffering from great saphenous vein or small saphenous vein insufficiency in combination with symptomatic chronic venous insufficiency and complicating comorbidities were treated with a modified endovascular cyanoacrylate glue application technique. RESULTS The immediate success rate of the treatment was 98 %. In follow-up intervals of six weeks, six months, one year, and two years, the anatomical success rates of embolization (recanalization of no more than 5 cm of the junction) were 98, 96, 94, and 94 %, respectively. At identical intervals the venous insufficiency was scored according to the Aberdeen Varicose Vein Questionnaire and the American Venous Clinical Severity Score. In both cases, improvement was demonstrated over the two-year follow-up, with a 0.5 % significance level. Specific clinical signs of venous insufficiency were also evaluated, such as pain, oedema, clearance of varicose veins, and healing of venous ulceration. One severe complication - a pulmonary embolism - was reported, without consequences. CONCLUSIONS We demonstrated that treating insufficient saphenous veins with modified histoacryl application brought a relief from symptoms of venous insufficiency and that the efficiency of this technique is comparable to commonly used methods.

Abstract
BACKGROUND Worldwide, at least 200 million people are affected by peripheral vascular diseases (PVDs), including peripheral arterial disease (PAD), chronic venous insufficiency (CVI) and deep vein thrombosis (DVT). The high prevalence and serious consequences of PVDs have led to the development of several diagnostic tools and clinical guidelines to assist timely diagnosis and patient management. Given the increasing number of diagnostic methods available, a comprehensive review of available technologies is timely in order to understand their limitations and direct future development effort. MAIN BODY This paper reviews the available diagnostic methods for PAD, CVI, and DVT with a focus on non-invasive modalities. Each method is critically evaluated in terms of sensitivity, specificity, accuracy, ease of use, procedure time duration, and training requirements where applicable. CONCLUSION This review emphasizes the limitations of existing methods, highlighting a latent need for the development of new non-invasive, efficient diagnostic methods. Some newly emerging technologies are identified, in particular wearable sensors, which demonstrate considerable potential to address the need for simple, cost-effective, accurate and timely diagnosis of PVDs.

Abstract
Objectives To assess the current use of safety checklists among the American College of Phlebology (ACP) members and their interest in implementing a checklist supported by the ACP on their clinical practices; and to develop a phlebology safety checklist. Method Online surveys were sent to ACP members, and a phlebology safety checklist was developed by a multispecialty team through the ACP Leadership Academy. Results Forty-seven percent of respondents are using a safety checklist in their practices; 23% think that a phlebology safety checklist would interfere or disrupt workflow; 79% answered that a phlebology safety checklist could improve procedure outcomes or prevent complications; and 85% would be interested in implementing a phlebology safety checklist approved by the ACP. Conclusion A phlebology safety checklist was developed with the intent to increase awareness on patient safety and improve outcome in phlebology practice.

Abstract
Objective This study aims to present the early results of a retrospective study of the use of novel n-butyl-2-cyanoacrylate (VenaBlock)-based nontumescent endovenous ablation with a guiding light for the treatment of patients with varicose veins. Methods Patients with lower limb venous insufficiency were treated with n-butyl-2-cyanoacrylate (VenaBlock Venous Closure System) between April 2016 and July 2016. The study enrolled adults aged 21–70 years with symptomatic moderate to severe varicosities (C2–C4b) and great saphenous vein reflux lasting longer than 0.5 s with great saphenous vein diameter between 5.5 and 15 mm assessed in the standing position. No compression stockings were used after the procedure. Duplex ultrasound imaging and clinical follow-up were performed on the third day, first month, sixth month, and 12th month. Clinical, etiological, anatomical, pathophysiological classification; venous clinical severity score; and completed Aberdeen varicose vein questionnaire were recorded. Results Five hundred thirty-eight patients with great saphenous vein incompetency underwent n-butyl-2-cyanoacrylate ablation. The mean ablation length was 25.69 ± 4.8 cm, and the average amount of n-butyl-2-cyanoacrylate delivered was 0.87 ± 0.15 ml. The mean procedure time was 11.7 ± 4.9 min. Procedural success was 100%, and complete occlusion was observed after treatment and at the third-day follow-up. We observed ecchymosis in five patients (1.00%) at the entry site at the third-day follow-up. Phlebitis was encountered with six (1.20%) patients. No skin pigmentation, hematoma, paresthesia, deep vein thrombosis, or pulmonary embolism was observed. Kaplan–Meier analysis yielded an occlusion rate of 99.4% at the 12-month follow-up. All patients had significant improvement in venous clinical severity score and Aberdeen varicose vein questionnaire scores postoperatively ( p <0.0001). Venous clinical severity score scores decreased from 5.43 ± 0.87 to 0.6 ± 0.75. Aberdeen varicose vein questionnaire scores decreased from 18.32 ± 5.24 to 4.61 ± 1.42. Conclusions The procedure appears to be feasible, safe, and efficient in treating the great majority of incompetent great saphenous veins with this technique.

BACKGROUND Chronic lower extremity venous disease (LECVD) is twice as prevalent as coronary heart disease, and invasive therapies to treat LECVD accounted for an estimated $290 million in Medicare expenditures in 2015. Despite increasing use of these invasive therapies, their comparative effectiveness is unknown. METHODS We conducted a systematic review and meta-analysis of treatments for patients (symptomatic and asymptomatic) with lower extremity varicosities and/or lower extremity chronic venous insufficiency/incompetence/reflux. We searched PubMed, Embase, and the Cochrane Database of Systematic Reviews for relevant English-language studies published from January 2000 to July 2016. We included comparative randomized controlled trials (RCTs) with >20 patients and observational studies with >500 patients. Short-, intermediate-, and long-term outcomes of placebo, mechanical compression therapy, and invasive therapies (surgical and endovascular) were included. Quality ratings and evidence grading was performed. Random-effects models were used to compute summary estimates of effects. RESULTS We identified a total of 57 studies representing 105,878 enrolled patients, including 53 RCTs comprised of 10,034 patients. Among the RCTs, 16 were good quality, 28 were fair quality, and 9 were poor quality. Allocation concealment, double blinding, and reporting bias were inadequately addressed in 25 of 53 (47%), 46 of 53 (87%), and 15 of 53 (28.3%), respectively. Heterogeneity in therapies, populations, and/or outcomes prohibited meta-analysis of comparisons between different endovascular therapies and between endovascular intervention and placebo/compression. Meta-analysis evaluating venous stripping plus ligation (high ligation/stripping) compared with radiofrequency ablation revealed no difference in short-term bleeding (odds ratio [OR]=0.30, 95% CI -0.16 to 5.38, P=.43) or reflux recurrence at 1-2 years (OR=0.76, 95% CI 0.37-1.55, P=.44). Meta-analysis evaluating high ligation/stripping versus endovascular laser ablation revealed no difference in long-term symptom score (OR 0.02, 95% CI -0.19 to 0.23, P=.84) or quality of life at 2 years (OR 0.06, 95% CI -0.12 to 0.25, P=.50). CONCLUSIONS The paucity of high-quality comparative effectiveness and safety data in LECVD is concerning given the overall rise in endovascular procedures. More high-quality studies are needed to determine comparative effectiveness and guide policy and practice.

Abstract
ntroduction This is a single-center clinical study for the evaluation of safety, efficacy, and performance of endovenous cyanoacrylate (Sapheon Venaseal Closure System, now Medtronic Medical) for the treatment of great saphenous vein (GSV) reflux. ethods Primary outcome measures included the GSV obliteration, with clinical recurrence on follow up as detected by serial clinical and duplex examinations of patients at 1 week, 1 month, 6 months, and 1 year. Venous clinical severity score (VCSS), Aberdeen varicose vein questionnaire (AVVQ), Short Form Health Survey 36 Item (SF-36) questionnaires were used at clinical follow up. Diameter of the GSV, treatment length of the GSV, and pretreatment clinical severity of the varicose vein were analyzed to predict recanalization using Cox regression analysis. esults Fifty-seven legs in 29 patients with primary varicose veins were included. One week follow-up duplex showed successful obliteration of the GSV in all except one of the legs. Two legs had minimal extension of thrombus to deep vein. None of the patients had deep venous thrombosis. All the patients were discharged the same day of operation. Median time to return to work was 1 day (range 1–16 days). Our VCSS, AVVQ, and the SF-36 physical and mental scores changed from a mean of 6.91, 23.66, 44.24, 54.26 at baseline to 2.43, 6.10, 43.85, 52.50 at 1 month post operation, respectively. Kaplan–Meier analysis showed that the GSV closure rates were 98.2%, 94.3%, 89.7%, and 78.5% at post-op 1 week, 1 month, 6 months, and 1 year, respectively. With median follow-up period of 9 months (range 1–13 months), no clinical recurrence of varicosity was observed. Mean GSV diameter ≥8 mm was a significant predictor for recanalization (hazard ratio 6.92, 95%CI 1.34–35.67, p = 0.021). onclusion This study showed that the use of endovenous cyanoacrylate in the treatment of the GSV reflux was safe. All patients had symptomatic improvement as shown by the VCSS and AVVQ.

Abstract
This is a prospective trial investigating endovenous radiofrequency ablation with the EVRF system for the treatment of symptomatic varicose veins. Primary endpoints include one-year anatomical and clinical success and procedure-related complications. Secondary endpoints include adjunctive procedures and recanalization rates, periprocedural pain assessment, and time return to normal activities. In 60 patients with 74 limbs, 58 great saphenous vein, 11 small saphenous vein, 2 anterior accessory saphenous vein, and 3 perforators were ablated. Additional ablations for further improvement were necessary in 28.4%. Clinical success was 94.6%. Anatomical success was 96.0% at one month and 89.2% at one year. Primary ablation success was 77%. Revascularization occurred in 12.1%. Clinically driven repeat ablation rate was 4.0%. Perforator ablation due to segmental revascularization was performed in 5.4%. Complications included one puncture-site infection, three scars, two cases of transient paresthesia, and one skin pigmentation. Periprocedural mean pain score was 2.4 ± 2.6. In 27.0% cases, the patients used analgesics and mean time return was 1.2 ± 0.5 days. The EVRF system yields satisfactory clinical and anatomical midterm outcomes with very low complication rates.

Abstract
PURPOSE To investigate and compare the anatomical success rates and complications of the treatment modalities for small saphenous vein (SSV) incompetence. METHODS A systematic literature search was performed in PubMed, EMBASE, and the Cochrane Library on the following therapies for incompetence of SSVs: surgery, endovenous laser ablation (EVLA), radiofrequency ablation (RFA), ultrasound-guided foam sclerotherapy (UGFS), steam ablation, and mechanochemical endovenous ablation (MOCA). The search found 49 articles (5 randomized controlled trials, 44 cohort studies) reporting on the different treatment modalities: surgery (n=9), EVLA (n=28), RFA (n=9), UGFS (n=6), and MOCA (n=1). A random-effects model was used to estimate the primary outcome of anatomical success, which was defined as closure of the treated vein on follow-up duplex ultrasound imaging. The estimate is reported with the 95% confidence interval (CI). Secondary outcomes were technical success and major complications [paresthesia and deep vein thrombosis (DVT)], given as the weighted means. RESULTS The pooled anatomical success rate was 58.0% (95% CI 40.9% to 75.0%) for surgery in 798 SSVs, 98.5% (95% CI 97.7% to 99.2%) for EVLA in 2950 SSVs, 97.1% (95% CI 94.3% to 99.9%) for RFA in 386 SSVs, and 63.6% (95% CI 47.1% to 80.1%) for UGFS in 494 SSVs. One study reported results of MOCA, with an anatomical success rate of 94%. Neurologic complications were most frequently reported after surgery (mean 19.6%) and thermal ablation (EVLA: mean 4.8%; RFA: mean 9.7%). Deep venous thrombosis was a rare complication (0% to 1.2%). CONCLUSION Endovenous thermal ablation (EVLA/RFA) should be preferred to surgery and foam sclerotherapy in the treatment of SSV incompetence. Although data on nonthermal techniques in SSV are still sparse, the potential benefits, especially the reduced risk of nerve injury, might be of considerable clinical importance.

Abstract
Laser ablation involves the delivery of laser light through a glass fibre placed into the lumen of a refluxing vein. This energy is converted into heat inducing a permanent, non-thrombotic occlusion. This highly effective and safe approach has significant advantages over traditional surgical treatment and has driven the endovenous revolution in the management of varicose veins. This chapter will explore the mechanism of action, present the evidence of laser' clinical and cost effectiveness, and analyse specific and generic aspects of laser ablation technique.

Abstract
Background This was a prospective study of radiofrequency segmental thermal ablation (RFA) for the treatment of incompetent varicose great saphenous veins (GSVs). The present report describes long-term follow-up at 5 years. Methods The 5-year follow-up of this multicentre European study included assessment of the Venous Clinical Severity Score (VCSS), and GSV occlusion and reflux on duplex imaging. Results A total of 225 patients had 295 GSVs treated by RFA, achieving an initial vein occlusion rate of 100 per cent. With 80·0 per cent compliance, Kaplan–Meier analyses showed a GSV occlusion rate of 91·9 per cent and a reflux-free rate of 94·9 per cent at 5 years. Among the 15 GSVs noted with reflux during follow-up, only three showed full recanalization of the GSV at 1 week, 6 months and 3 years. Of the 12 legs with partial recanalization, reflux originated at the saphenofemoral junction in ten, with a mean length of the patent segment of 5·8 (range 3·2–10) cm; only six patients were symptomatic. Mean(s.d.) VCSS scores improved from 3·9(2·1) at baseline to 0·6(1·2), 0·9(1·3) and 1·3(1·7) at 1, 3 and 5 years. Conclusion At 5 years RFA proved to be an efficient endovenous treatment for incompetent GSVs in terms of sustained clinical and anatomical success for the vast majority of treated patients.

Abstract
OBJECTIVE Cyanoacrylate (CA) embolization of refluxing great saphenous veins (GSVs) has been previously described. The outcomes from a multicenter study are still lacking. METHODS A prospective multicenter study was conducted in seven centers in four European countries to abolish GSV reflux by endovenous CA embolization. Neither tumescent anesthesia nor postinterventional compression stockings were used. Varicose tributaries remained untreated until at least 3 months after the index treatment. Clinical examination, quality of life assessment, and duplex ultrasound evaluation were performed at 2 days and after 1, 3, 6, and 12 months. RESULTS In 70 patients, of whom 68 (97.1%) were available for 12-month follow-up, 70 GSVs were treated. Two-day follow-up showed one proximal and one distal partial recanalization. Three additional proximal recanalizations were observed at 3-month (n = 2) and 6-month (n = 1) follow-up. Cumulative 12-month survival free from recanalization was 92.9% (95% confidence interval, 87.0%-99.1%). Mean (standard deviation) Venous Clinical Severity Score improved from 4.3 ± 2.3 at baseline to 1.1 ± 1.3 at 12 months. Aberdeen Varicose Vein Questionnaire score showed an improvement from 16.3 at baseline to 6.7 at 12 months (P < .0001). Side effects were generally mild; a phlebitic reaction occurred in eight cases (11.4%) with a median duration of 6.5 days (range, 2-12 days). Pain without a phlebitic reaction was observed in five patients (8.6%) for a median duration of 1 day (range, 0 -12 days). No serious adverse event occurred. Paresthesia was not observed. CONCLUSIONS Endovenous CA embolization of refluxing GSVs is safe and effective without the use of tumescent anesthesia or compression stockings.

Abstract
PURPOSE We aimed to assess the technical feasibility of targeted endovenous treatment of Giacomini vein insufficiency (GVI)-associated varicose disease and report our early results. METHODS We retrospectively screened 335 patients with varicose disease who underwent endovenous laser ablation from September 2011 to January 2013, and determined 17 patients who underwent Giacomini vein ablation. Using a targeted endovenous treatment approach considering the reflux pattern, all healthy great saphenous veins (GSV) or vein segments were preserved while all insufficient veins (Giacomini vein, perforator veins, small saphenous vein, anterior accessory GSV, major tributary veins, or incompetent segments of the GSV) were ablated. Treatment success was analysed using Doppler findings and clinical assessment scores before and after treatment. RESULTS Targeted endovenous treatment was technically successful in all cases. Seven GSVs were preserved totally and three GSVs were preserved partially (10/17, 58%), with no major complications. Clinical assessment scores and Doppler findings were improved in all cases. CONCLUSION Targeted endovenous treatment of GVI-associated varicose disease is safe and effective. In majority of GVI cases saphenous vein can be preserved using this approach.

Abstract
BACKGROUND A Health Technology Assessment was conducted to evaluate the relative clinical effectiveness and cost-effectiveness of minimally invasive techniques (foam sclerotherapy (FS), endovenous laser ablation (EVLA) and radiofrequency ablation (RFA)) for managing varicose veins, in comparison with traditional surgery. METHODS A systematic review of randomized clinical trials (RCTs) was undertaken to assess the effectiveness of minimally invasive techniques compared with other treatments, principally surgical stripping, in terms of recurrence of varicose veins, Venous Clinical Severity Score (VCSS), pain and quality of life. Network meta-analysis and exploratory cost-effectiveness modelling were performed. RESULTS The literature search conducted in July 2011 identified 1453 unique citations: 31 RCTs (51 papers) satisfied the criteria for effectiveness review. Differences between treatments were negligible in terms of clinical outcomes, so the treatment with the lowest cost appears to be most cost-effective. Total FS costs were estimated to be lowest, and FS was marginally more effective than surgery. However, relative effectiveness was sensitive to the model time horizon. Threshold analysis indicated that EVLA and RFA might be considered cost-effective if their costs were similar to those for surgery. These findings are subject to various uncertainties, including the risk of bias present in the evidence base and variation in reported costs. CONCLUSION This assessment of currently available evidence suggests there is little to choose between surgery and the minimally invasive techniques in terms of efficacy or safety, so the relative cost of the treatments becomes one of the deciding factors. High-quality RCT evidence is needed to verify and further inform these findings.

Abstract
Objectives To evaluate the safety and effectiveness of endovenous cyanoacrylate-based embolization of incompetent great saphenous veins. Methods Incompetent great saphenous veins in 38 patients were embolized by cyanoacrylate bolus injections under ultrasound guidance without the use of perivenous tumescent anesthesia or graduated compression stockings. Follow-up was performed over a period of 24 months. Result Of 38 enrolled patients, 36 were available at 12 months and 24 were available at 24 months follow-up. Complete occlusion of the treated great saphenous vein was confirmed by duplex ultrasound in all patients except for one complete and two partial recanalizations observed at, 1, 3 and 6 months of follow-up, respectively. Kaplan-Meier analysis yielded an occlusion rate of 92.0% (95% CI 0.836–1.0) at 24 months follow-up. Venous Clinical Severity Score improved in all patients from a mean of 6.1 ± 2.7 at baseline to 1.3 ± 1.1, 1.5 ± 1.4 and 2.7 ± 2.5 at 6, 12 and 24 months, respectively ( p < .0001). Edema improved in 89% of legs (n = 34) at 48 hours follow-up. At baseline, only 13% were free from pain. At 6, 12 and 24 months, 84%, 78% and 64% were free from leg pain, respectively. Conclusions The first human use of endovenous cyanoacrylate for closure of insufficient great saphenous veins proved to be feasible, safe and effective. Clinical efficacy was maintained over a period of 24 months.

Abstract
OBJECTIVE This article will describe the elements of performing a thorough venous ultrasound evaluation of the lower extremity in patients with manifestations of chronic venous disorder. The emphasis will be on the evaluation of superficial venous reflux. Only the specific aspects of the evaluation of the deep system pertaining to chronic venous disease will be discussed. CONCLUSION Duplex ultrasound requires the examiner to solve a puzzle to explain the patient's clinical manifestations. Patients who have been treated with surgery, thermal ablation, or ultrasound-guided sclerotherapy will require duplex ultrasound after treatment to identify complications, gauge the extent of treatment success, and evaluate the cause for any recurrence.

Abstract
The postthrombotic syndrome (PTS) is a frequent cause of chronic pain, swelling, ulceration, and disability in patients with lower extremity deep vein thrombosis (DVT). As interventional radiologists are consulted on more patients with chronic DVT and PTS, their management strategies must be informed by a balanced understanding of the different facets of chronic DVT care and the available treatment options. This article provides an overview of the important elements of a multifaceted approach to the management of patients with PTS that includes pharmacological, physiological, and endovascular aspects of care.

Abstract
OBJECTIVE The primary objective of this study was to assess the feasibility of an endovenous cyanoacrylate (CA) adhesive implant, delivered with a catheter-based administration system engineered with a nonstick surface, for the treatment of incompetent great saphenous veins (GSVs). The primary safety end point was the rate of serious adverse events related to the procedure. The primary efficacy end point was vein occlusion during follow-up. Secondary end points included the rate of all adverse events and the change in Venous Clinical Severity Scores (VCSSs). METHODS Thirty-eight incompetent GSVs in 38 symptomatic patients were treated by catheter deployment of CA under ultrasound guidance via a repetitive bolus injection algorithm. By protocol design, perivenous tumescent anesthesia and compression stockings were omitted. Duplex ultrasound imaging and clinical follow-up were performed immediately after the procedure, at 48 hours, and 1, 3, 6, and 12 months. RESULTS The mean total volume of endovenous CA delivered was 1.3 ± 0.4 mL (range, 0.6-2.3 mL). Immediately after the procedure and at the 48-hour follow-up, the 38 patients (100%) demonstrated complete closure of the GSV. One complete and two partial recanalizations were observed during follow-up at 1, 3, and 6 months, respectively. Kaplan-Meier analysis yielded an occlusion rate of 92% at 12 months of follow-up. Side effects were generally mild and self-limited, most frequently, phlebitis in six patients (15.8%) requiring nonsteroidal anti-inflammatory drugs for an average of 5.7 days. Eight patients (21.1%) showed thread-like thrombus extensions into the common femoral vein of a mean length of 12.6 mm (range, 3.5-35 mm), which resolved spontaneously without anticoagulation. VCSS improved in all patients from a mean of 6.1 ± 2.7 at baseline to 1.5 ± 1.4 at 12 months (P < .0001). Edema improved in 34 legs (89%) at the 48-hour follow-up. At the 12-month follow-up, and without additional adjunctive treatment, 18 legs (50%) were free from visible varicosities and an additional eight legs (25%) showed limited varicosities. CONCLUSIONS The first human use of endovenous CA for closure of insufficient GSVs proved to be feasible, safe, and effective. Endovenous delivery of CA may prove to be an alternative for the correction of saphenous incompetence and may be used without tumescent anesthesia and medical compression stockings.
