Introduction: We aim to highlight a potentially morbid consequence of foam-sclerotherapy for the treatment of varicose veins.
Case Report: We report a case of a 41-year-old woman with no significant medical history who presented to the emergency department with sudden onset of focal neurologic deficits. She had undergone varicose vein treatment with foam sclerotherapy 2 days prior. Magnetic resonance imaging of the brain showed acute cerebellar infarct. Computed tomography angiography was unremarkable. Transesophageal echocardiography showed the presence of a very small patent foramen ovale.
Discussion: Transient neurologic symptoms reported in patients undergoing venous foam sclerotherapy might have been transient ischemic attacks or acute ischemic strokes. The risk of these neurologic complications should be explained to all patients undergoing foam sclerotherapy so they can make an informed decision of screening echocardiography prior to the procedure.
Conclusion: Onset of neurologic symptoms can be immediate or delayed in patients undergoing venous foam sclerotherapy. Early recognition of neurologic deficits resulting from paradoxical gas embolism and its treatment with hyperbaric oxygen can prevent permanent disability.

Purpose: Determine the rate of incidence, risk factors, and management for developing venous thromboembolism (VTE) in patients undergoing radiofrequency ablation (RFA) and ultrasound-guided foam sclerotherapy (UGFS) for varicose veins.
Methods: All charts of patients undergoing venous ablation from 2016 to 2023 were reviewed at a rural vein treatment clinic. The incidence of VTE was noted and a chart review was completed to identify risk factors for VTE, EHIT score, EFIT score, and management.

Chronic venous disease has a major impact on the quality of life of millions of patients. Large randomized controlled trials have established ultrasound-guided foam sclerotherapy (UGFS) as a safe and effective treatment option for both saphenous vein insufficiency and tributary disease. Ultrasound guidance is a critical component of sclerotherapy of non-visible veins.

Blood flow from the saphenofemoral junction(SFJ) tributaries may cause recurrence of varicose veins. Flush occlusion is defined as the total occlusion of the great saphenous vein(GSV) right to the saphenofemoral junction. The purpose of this study was to evaluate the efficacy and safety of flush endovenous thermal ablation with saphenofemoral junction tributary occlusion.

Background: Treatment of symptomatic varicose veins has changed dramatically in the last few years with guidelines now recommending endovenous surgery as first-line intervention. Previously, this was achieved by laser or radiofrequency ablation of the target vein, requiring infiltration of tumescent anesthesia to reduce the risks of thermal damage to surrounding tissue. Endovenous cyanoacrylate injection (VenaSeal™) is a nonthermal, nontumescent endovenous closure technique, increasing patient comfort and is readily performed under local anesthesia only and thus is a feasible technique for in-room treatment.
