Venous Thermal Ablation

Varicosis is a chronic progressive disease characterized by varicose veins of the lower extremities. Pain, swelling and heaviness of the legs are typical symptoms. These symptoms are caused by a pathological venous reflux, arising from a weakness of the vein wall and progressive venous insufficiency. The indications for invasive surgery are the symptomatic clinical, etiological, anatomical, pathophysiological (CEAP) stages C2s-C6. Compression therapy and venoactive drugs can be recommended for conservative therapy...

OBJECTIVES: This review article provides an updated review of a relatively common pathology with various manifestations. Superficial venous diseases (SVD) are a broad spectrum of venous vascular disease that predominantly affects the body's lower extremities. The most serious manifestation of this disease includes varicose veins, chronic venous insufficiency, stasis dermatitis, venous ulcers, superficial venous thrombosis, reticular veins, and spider telangiectasias. METHODS: The anatomy, pathophysiology, and risk factors of SVD were discussed during this review...

BACKGROUND: Polidocanol endovenous microfoam (PEM) has been used to treat lower extremity venous reflux for almost a decade with specific advantage in below knee (BK) truncal veins where thermal ablation poses a risk for injury to adjacent nerves. Current literature in the BK segment often examines short-term outcomes with modest sample sizes. We aim to identify factors associated with recanalization and reintervention in this subset of patients. METHODS: We performed a retrospective study of a prospectively maintained database of patients from a single institution who underwent PEM ablation for BK great saphenous vein (GSV) and small saphenous vein (SSV) reflux...

OBJECTIVE: To investigate whether compression therapy after thermal ablation of varicose veins can improve the prognosis of patients. METHODS: Systematic research were applied for Chinese and English electronic databases(PubMed, Web of Science, Cochrane Library, CNKI, Wanfang, VIP Databases). Eligible prospective studies that comparing the efficacy of compression therapy and non-compression therapy on patients after thermal ablation of varicose veins were included...

OBJECTIVE: The necessary training and certification of providers performing venous ablation has become a topic of debate in recent years. As venous interventions have shifted away from the hospital, the diversity of provider backgrounds has increased. We aimed to characterize superficial venous ablation practice patterns associated with different provider types. METHODS: We analyzed Medicare fee-for-service data from 2010 through 2018. Procedures were identified by their Current Procedural Terminology (CPT) code and included radiofrequency ablation, endovenous laser ablation, chemical adhesive ablation (i...

OBJECTIVE: Endovenous thermal ablation (EVTA) is a prevalent treatment option in patients with severe venous disease. However, the decision to intervene on patients with less severe disease (CEAP C2 & C3) is less clear and becomes further complicated in patients suffering from obesity, a pathology known to increase venous disease symptom severity. Therefore, the objective of this study was to use the Society for Vascular Surgery Vascular Quality Initiative (SVS-VQI) database to evaluate outcomes following EVTA in obese patients with CEAP C2 and C3 venous insufficiency...

OBJECTIVE: The goal of this study was to analyze trends in treatment access for chronic superficial venous disease and to identify disparities in care. METHODS: This study was a retrospective study and exempt from Institutional Review Board approval. The American College of Surgeon - National Surgical Quality Improvement Program (NSQIP) database was used to identify patients who underwent vein stripping (VS) and endovenous procedures for treatment of chronic superficial venous disease...

Vascular malformations are congenital, non-neoplastic lesions that arise secondary to defects in angiogenesis. Vascular malformations are divided into high-flow (arteriovenous malformation) and low-flow (venous malformations and lymphatic malformations). Magnetic resonance imaging (MRI) is the standard for pre-and post-intervention assessments, while ultrasound (US), X-ray fluoroscopy and computed tomography (CT) are used for intra-procedural guidance. Sclerotherapy, an image-guided therapy that involves the injection of a sclerosant directly into the malformation, is typically the first-line therapy for treating low-flow vascular malformations...

BACKGROUND AND OBJECTIVE: Endovenous radiofrequency ablation (RFA) and laser ablation (LA) have been commonly used for treating lower extremity varicose veins (LEVV). Their therapeutic effects have been widely recognized compared with conventional surgery. However, there have been some controversies regarding the choice between RFA and LA. The objective of our study was to conduct a systematic review and meta-analysis comparing the early and long-term outcomes of RFA and LA. METHODS: A comprehensive search was performed in the PubMed, Embase, and Cochrane databases to identify relevant literature on endovenous thermal ablation (ETA) for primary LEVV up until June 2023...

BACKGROUND AND OBJECTIVES: Genicular nerve radiofrequency ablation (GNRFA) is an emerging procedure used to relieve pain from severe knee osteoarthritis. While there have been rare reports of significant complications, their incidence has not been well established. The objective of this study was to examine complication rates at 30 and 90 days post treatment as well as characterize opioid-prescribing patterns before and after treatment. METHODS: A large national database was queried to identify patients undergoing GNRFA from 2015 to 2022 and matched to control cohorts composed of patients receiving either intra-articular corticosteroid (CSI) or hyaluronic acid injection (HAI) of the knee...

OBJECTIVES: Polidocanol endovenous microfoam (MFA) is approved by the US Food and Drug Administration for great saphenous vein (GSV) closure, yet there is little published data on the subsequent risk of ablation related thrombus extension (ARTE). Recent societal practice guidelines recommend against routine post-procedure duplex ultrasound (DU) following thermal ablation of the GSV in asymptomatic patients. At present, limited data does not allow this recommendation to extend to MFA. Our aim is to identify characteristics and outcomes associated with ARTE following MFA versus radiofrequency ablation (RFA)...

OBJECTIVE: We aim to report on the Laser-Sclerosing Foam Hybrid Treatment (LSFHT) and its outcomes when used on patients with great saphenous vein (GSV) insufficiency. METHODS: This was a single center retrospective cohort study on patients with GSV insufficiency that were treated with the LSFHT technique, a surgical procedure that comprises the use of both sclerosing foam and endovenous ablation and avoids the use of tumescent anesthesia. Occlusion rates and complications were reported...

BACKGROUND: The study aims to identify the incidence of symptomatic and asymptomatic venous thromboembolism (VTE) after minimally invasive varicose vein surgery and to assess the predictability of the Caprini risk score (CRS). METHODS: CAPrini Score In Venous Surgery (NCT03041805) is a registry-based prospective study that enrolls patients undergoing minimally invasive open (high ligation, stripping, miniphlebectomy) and endovascular (thermal and non-thermal ablation) surgery on varicose veins...

The FOVELASS study, a randomised multicentre trial published this year by the French Society of Phlebology, confirms the technical superiority of endovenous laser over sclerosing foam in the treatment of small saphenous vein incompetence, over a 3-year follow-up. However, this study also validates the good clinical results of foam, equivalent to those of endovenous laser, already observed in other clinical studies on the great saphenous vein. Thermal ablation has therefore consolidated its leading position in the treatment of saphenous veins but depending on the anatomical configuration of the veins and the economic context, sclerosing foam, which is widely applicable, highly versatile, and cost-effective, may be an interesting alternative...

Lower extremity deep venous thrombosis (LEDVT) affects patient's quality of life for a long time, and even causes pulmonary embolism, which threatens human health. Current anticoagulant drugs in clinical treatment are hampered by the risk of bleeding due to poor targeting and low drug penetration. Here, we used platelet (PLT)-like biological targeting to enhance the delivery and accumulation of nanomedicines in thrombus and reduce the risk of bleeding. Meanwhile, the parallel strategy of "thrombus thermal ablation and anticoagulation" was applied to increase the permeability of drugs in thrombus and achieve the optimal antithrombotic effect...

OBJECTIVES: Independent internal and external validation of three previously published CT-based radiomics models to predict local tumor progression (LTP) after thermal ablation of colorectal liver metastases (CRLM). MATERIALS AND METHODS: Patients with CRLM treated with thermal ablation were collected from two institutions to collect a new independent internal and external validation cohort. Ablation zones (AZ) were delineated on portal venous phase CT 2-8 weeks post-ablation...

OBJECTIVE: The objective of this study was to better understand the safety and efficacy of laser interstitial thermal therapy (LITT) for children with medically refractory epilepsy. METHODS: Thirty-seven consecutive pediatric epilepsy patients at a single pediatric center who underwent LITT ablation of epileptogenic foci between May 2017 and December 2021 were retrospectively reviewed. Patient demographics, medication use, seizure frequency, prior surgical interventions, procedural details, and pre- and postoperative seizure history were analyzed...

OBJECTIVE: Subependymal giant cell astrocytomas (SEGAs) are WHO grade 1 tumors associated with tuberous sclerosis that classically arise from the ventricular wall near the caudate groove and foramen of Monro. Laser interstitial thermal therapy (LITT) is a minimally invasive surgical technique, which works by heating a stereotactically placed laser fiber to ablative temperatures under MRI thermometry monitoring. In this paper, the authors present LITT as a surgical alternative to open resection of SEGAs...

Primary aldosteronism (PA) is the most prevalent form of secondary hypertension and is most commonly caused by an adrenal adenoma or bilateral adrenal hyperplasia. Minimally invasive adrenalectomy is the treatment of choice for unilateral disease. Here, we report the case of a 57-year-old man with previous bladder cancer who was referred for evaluation of resistant hypertension and hypokalemia. Diagnostic workup indicated PA with computed tomography imaging revealing a left adrenal adenoma and adrenal venous sampling lateralizing to the left adrenal...

BACKGROUND: Chronic venous disease is a frequent and prevalent pathology. Its surgical treatment has been shown to be cost-effective. Thermal endoablation performed as major outpatient surgery (MAS) is the technique of choice. OBJECTIVE: To know the satisfaction of patients after MAS and the quality of care provided. METHOD: Observational, descriptive, cross-sectional study, carried out between January 2019 and March 2020. A survey was carried out on patients who underwent endovascular radiofrequency thermoablation in two hospitals in Spain, consisting of two questionnaires: one ad hoc and one another of satisfaction (SERCAL)...
