sclerosing foam

INTRODUCTION: Laser and radiofrequency ablation are two thermal ablation methods currently widely used to treat lower limb venous insufficiency. However, very few studies have been conducted on the use of microwaves, a form of thermal ablation, for the treatment of small saphenous vein (SSV) insufficiency. This study aimed to examine the efficacy and safety of endovenous microwave ablation (EMA) for the treatment of SSV insufficiency. METHODS: The clinical data of 126 patients (126 lower limbs) with SSV insufficiency (SSV trunk reflux time ≥ 500 ms on lower limb color Doppler ultrasound) treated at the Surgery Department of The Sixth People's Hospital of Zhuji from January 2020 to June 2022 were analyzed retrospectively; 64 patients underwent EMA and 62 underwent endovenous laser ablation (EVLA)...

BACKGROUND: Sclerotherapy is a cornerstone of the treatment of chronic venous disease, despite some technical aspects (e.g., sclerosant liquid agent concentration [SLAC] and contact time between sclerosant agent and vein wall [ctSA/VW]) to maximize outcomes remain an unsolved problem and a source of debate. An innovative three-balloon catheter has been developed to allow sclerotherapy in empty vein conditions (Empty Vein Ablation technique, EVA), revolutionizing the definition of SLAC and ctSA/VW...

BACKGROUND: The Tessari method is commonly used in sclerotherapy for producing foam, involving 2 syringes pushed back and forth 20 times with the use of a 3-way connector. Many factors affect the foam stability which is crucial for clinical efficacy. OBJECTIVE: This study aimed to identify the optimal pushing rate which may impact the foam stability. MATERIALS AND METHODS: Polidocanol (POL) solution (1% and 3%) was used to make sclerosant foam via the Tessari method, with a total of 20 pushes performed at different time durations: 10, 15, 20, 25, 30, 35, and 40 seconds...

Varicoceles are dilated veins within the pampiniform plexus and are relatively common in the general male population. The spermatic vein has many branches in the scrotal segment and then gradually merges into 1-2 trunks after passing through the internal inguinal ring. The key to a successful varicocelectomy is to ligate all the spermatic veins while protecting the testicular arteries and spermatic lymphatic vessels from damage. The small veins, including the branches of spermatic veins and collateral veins, are easily missed for ligation during conventional high ligation of varicocele, which has been suggested as a major cause of postoperative recurrence...

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...

INTRODUCTION: This study aimed to investigate the outcome of hybrid endovenous laser ablation (EVLA, 1470 nm) and radiofrequency ablation (RFA) procedures for varicose veins (VVs). MATERIAL AND METHODS: We retrospectively analysed the clinical data of patients from July 2019 to December 2020. Eighty-four patients (121 limbs) underwent a hybrid EVLA procedure, and 108 patients (151 limbs) underwent an RFA procedure. The outcomes, venous clinical severity score (VCSS), chronic venous disease quality-of-life questionnaire (CIVIQ-20) score, and recurrence at 1, 6, and 12 months were collected...

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...

PURPOSE: This study investigates the usefulness of antegrade variceal embolization using sclerosant foam to evaluate technical success and clinical outcomes in cases of hypertensive variceal bleeding. METHODS: A total of 16 patients underwent percutaneous antegrade variceal embolization using foam sclerotherapy from August 2019 to January 2022. Among the patients, 12 cases were of gastroesophageal varices, two were rectal varices, and one case each was duodenal and jejunal varices, respectively...

Loss of vision after topical injection of sclerosant is a rare and uncommon complication. We describe a case with vision loss following the facial injections of physician-compounded (PCP) foam sclerotherapy which was created by room air. A 3-year-old boy underwent injection of 5ml polidocanol foamed with room air to treat the venous malformation on the cheek near the left orbit. The boy experienced the whole facial swelling on day 2 after the third injection, especially involving the left side, the visual acuity in the left eye was counting fingers at 30 cm and the swelling reduced at 7 days later after referral...

This systematic review and network meta-analysis investigated the clinical efficacy and safety of chemical agent injections in patients with varicose veins. PubMed, Embase, and Cochrane databases were searched for eligible studies where patients administered endovascular agents comprised an intervention group, and patients administered other interventions comprised the comparison group. The endovascular agents included foam and liquid form sclerotherapy or cyanoacrylate glue. The other interventions in this study included surgery, endovenous laser ablation (EVLA), radiofrequency ablation (RFA), and placebo...

BACKGROUND: Few studies have evaluated the safety and efficacy of treatment of cosmetic dorsal hand and chest/breast veins. OBJECTIVE: To retrospectively evaluate results of dorsal hand and chest vein foam sclerotherapy. MATERIALS AND METHODS: A retrospective chart review of dorsal hand and chest vein sclerotherapy patients at a dermatology practice was performed between January 2014 and April 2023. RESULTS: Fifty-five patients (54 female and 1 male patients) with a mean age of 55...

A hybrid treatment approach was used to successfully manage bilateral varicose veins in a 50-year-old female patient. The patient had venous insufficiency and presented with pain, swelling, and discoloration in her legs. The treatment plan consisted of two sessions of endovenous laser ablation (EVLA) to treat venous reflux, followed by two phlebectomies for residual bulging varicose veins. After a three-month follow-up, an ultrasound evaluation showed no venous reflux, indicating successful treatment. However, small reticular and spider veins remained, so the patient underwent four sessions of foam sclerotherapy using polidocanol as the sclerosant...

Orbital conjunctival epithelial cysts have traditionally been excised, with the risk of leaving behind remnants that may result in recurrences. We present an 18-year-old male who complained of a poorly retained prosthesis three years after a primary evisceration and polymethylmethacrylate (PMMA) ball implant. We performed cyst aspiration and injection foam sclerotherapy for the cyst, which resolved completely in six weeks, allowing the prosthesis to be retained comfortably. Aspiration and injection of sclerosing agents may result in the collapse of the cyst along with fibrosis of their walls with obliteration of the lumen, resulting in complete resolution...

Newer radiotherapy techniques, such as stereotactic body radiation, have been increasingly used as part of the treatment of cholangiocarcinomas, particularly as a bridge to liver transplantation. Although conformal, these high-dose therapies result in tissue injury in the peritumoral liver tissue. This retrospective study characterized the morphologic changes in the liver after stereotactic body radiation in a series of liver explant specimens with perihilar cholangiocarcinoma. The morphologic changes in the irradiated zone were compared against the nonirradiated background liver parenchyma to control for chemotherapy-related changes...
