endovenous thermal ablation

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 one week of the procedure. Our aim is to try to find whether there is a particular time period when post-operative duplex ultrasound scans should be performed to allow us to best diagnose recanalization...

OBJECTIVE: Endovenous microwave ablation (EMA) is a recently developed thermal ablation technique used in the treatment of lower limb varicose veins. However, its efficacy and safety have been largely understudied. In the present study, we sought to explore the clinical results of EMA and radiofrequency ablation (RFA) in treating lower limb varicose veins. METHODS: Patients who underwent EMA (n = 65) or RFA (n = 46) at our institute from September 2018 to September 2020 were included in this retrospective investigation...

Endovenous thermal methods are superseding surgical stripping for treating chronic superficial venous disease but require tumescent anesthesia and can cause heat-related nerve injuries. Endovenous cyanoacrylate ablation is a more recent technique that does not share these drawbacks. A retrospective observational study of consecutive adults managed with endovenous cyanoacrylate was conducted in 2018-2021 at a single university center. The follow-up was 18 months. We identified factors associated with target vein closure at 18 months and measured changes in quality of life using the generic 36-item Short-Form (SF-36) tool and the venous disease-specific VEINES-QOL/Sym questionnaire...

INTRODUCTION: Doctors have a legal requirement and duty of care to ensure patients are enabled to make an informed decision about their treatment, including discussion of the benefits, risks and alternatives to a procedure. A patient-centred approach to consent has been firmly established in Ireland, and fundamental to this is the ability to engage in a dialogue that offers comprehensible information to patients. Telemedicine has revolutionised the way we can deliver care to patients in the modern era of computers, tablets, and smartphones, and its use has been rapidly expanded...

<b/> Background: Traditionally, varicose vein treatment is predominately performed during the colder seasons. However, data whether higher outdoor temperatures affect the outcome and/or complication rate of endovenous thermal ablation (ETA) for treatment of symptomatic varicose veins are missing. Patients and methods: In this observational study, the medical records of all patients who had ETA of the great saphenous vein (GSV), accessory saphenous vein (ASV), or small saphenous vein (SSV) between September 2017 and October 2020 were reviewed...

Varicose veins of the lower extremities are a very common condition in vascular surgery. With advances in technology and medicine, minimally invasive endovenous thermal ablation has become the primary approach used to treat patients with moderate or severe varicose veins. Electrocoagulation for thermal ablation is a relatively simple and economical procedure, but standards vary according to location and some limitations exist. We report a case of a 58-year-old female patient with small saphenous varicose veins in the right lower extremity in which an electrocoagulation rod commonly used in laparoscopic surgery was innovatively used instead of a standard variable electrocoagulation device...

OBJECTIVE: The objective was to compare technical success, complications, and quality of life after thermal vs. non-thermal endovenous ablation for the treatment of superficial venous incompetence.

REVIEW METHODS: A systematic review and meta-analysis of randomised controlled trials was conducted using terms to identify relevant studies to be included...

OBJECTIVES: Radiofrequency-based procedure is one of the leading methods of endovenous thermal ablation. The most fundamental difference with regards to currently available radiofrequency ablation systems is the way of electric current flow given to the vein wall; bipolar segmental and monopolar ablation. This study aimed to compare the monopolar ablation method with conventional bipolar segmental endovenous radiofrequency ablation method for the management of incompetent saphenous veins...

OBJECTIVES: To assess the mid-term efficacy and safety of thermal and non-thermal endovenous ablation in the treatment of lower limb superficial venous insufficiency. METHOD: We performed a systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement and a Bayesian network meta-analysis. Primary endpoints were great saphenous vein (GSV) closure and venous clinical severity score (VCSS) score improvement...

Venous valve aplasia (or valvular rarefication) is a rare cause of chronic venous insufficiency. In the present report, we have described the case of a 33-year-old man with severe symmetric lower leg edema and heaviness and pain in both lower legs. Duplex ultrasound demonstrated severe venous insufficiency in the superficial and deep venous system of both legs. Further imaging examinations supported the diagnosis of venous valvular aplasia. Treatment consisted of endovenous thermal ablation of the great saphenous vein and small saphenous vein as well as consistent compression therapy, resulting in a marked reduction of his leg edema, heaviness, and pain...

OBJECTIVE: To compare long term outcomes after great saphenous vein (GSV) treatment with three radiofrequency (RF) thermal devices: Venefit (Closurefast), radiofrequency induced thermal therapy (RFITT), and endovenous radiofrequency (EVRF). DESIGN: A 72 month follow up of patients who were treated in the randomised 3RF study. METHODS: A total of 172 participants from the 3RF study were invited to take part in a single visit, long term, follow up study...

BACKGROUND: Mechanochemical ablation (MOCA) is an alternative method to endovenous thermal ablation (EVTA) for the treatment of superficial venous incompetence that does not require tumescent anaesthesia. The aim of this study was to compare the outcomes from RCTs of MOCA versus EVTA. METHODS: A search was conducted in MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials (CENTRAL). Meta-analysis inclusion was restricted to RCTs comparing MOCA against EVTA...

We report a 32-year-old female patient who was referred to a tertiary care hospital in Muscat, Oman, in 2021 with an iatrogenic arteriovenous fistula (AVF) that presented as a neck swelling which developed few weeks after an attempt of central venous catheterisation through the right internal jugular vein. The fistula was corrected surgically with a successful outcome. AVF is an abnormal communication between an artery and vein which can occur as a congenital anomaly, after trauma or iatrogenic following central venous catheter or endovenous thermal ablation...

OBJECTIVES: Few studies compared both ultrasound and histological approaches for the same series of patients with chronic venous disease (CVD). We aimed to assess the diagnostic performances of duplex ultrasound assessment (US) of Vein Wall Thickness (VWT) among patients with CVD. METHODS: 38 adults with primary varicose veins having undergone Great Saphenous Vein thermal ablation with phlebectomy, and agreeing to biopsy of the Posterior Accessory Great Saphenous Vein (PASV) were consecutively included in a two-center prospective study...

BACKGROUND: Linear Endovenous Energy Density (LEED) is the energy used per cm of vein in endovenous thermal ablation (EVTA) but does not include time. This study examines the effect of time during EVTA. METHOD: EVTA was performed in a previously validated porcine liver model. LEEDs of 40, 60, 80 and 100 J/cm, using different powers were repeated 5 times each. Thermal spread, tissue carbonisation and device-tissue sticking during treatment were recorded. RESULT: LEED positively correlated to thermal spread and carbonisation of the tissue...

OBJECTIVES: Saphenous vein reflux is one of the leading causes of cosmetic and functional disabilities.The recent ESVS guidelines recommend endovenous thermal ablation over surgery or sclerotherapy for the treatment of great saphenous vein (GSV) reflux in patients with chronic venous disease.The aim of this study is to compare different laser fiber tip configurations to outcome regarding technical success and incidence of complications. DESIGN: A retrospective analysis conducted on patients with documented GSV reflux from 2020 to 2022, comparing baseline parameters and outcome between 2 groups of laser tip fibers used; radial tip and jacketed tip...
