Background: Chronic venous disorders are common, with varicose veins occurring in ∼40% of the population. Venous leg ulcers affect 1% to 2% of the population, with the prevalence increasing ≤4% for those aged >65 years. Both conditions are expensive and together are responsible for ≤2% of the annual healthcare budget expenditure of Western societies.

Background: Superficial venous disease of the lower extremity has a significant impact on quality of life. Both truncal and tributary vein reflux contribute to this disease process. Endovenous foam sclerotherapy is a widely used technique throughout the world for the management of superficial venous reflux and ultrasound guidance improves its safety and efficacy.

Varicose veins afflict more than one in five Americans, and although varicose veins may be an asymptomatic cosmetic concern in some, many others experience symptoms of pain, aching, heaviness, itching, and swelling. More advanced venous disease can result from untreated venous insufficiency. The complications of chronic venous disease, including bleeding, thrombosis, and ulceration, are seen in up to 2 million Americans annually.

The coronavirus disease 2019 (COVID-19) global pandemic has resulted in diversion of healthcare resources to the management of patients infected with SARS-CoV-2 virus. Elective interventions and surgical procedures in most countries have been postponed and operating room resources have been diverted to manage the pandemic. The Venous and Lymphatic Triage and Acuity Scale was developed to provide an international standard to rationalise and harmonise the management of patients with venous and lymphatic disorders or vascular anomalies.

Background: Insurance approval for saphenous vein ablation is generally limited to junctional reflux involving the great saphenous vein (GSV) or small saphenous vein. This study was designed to investigate prevalence and disease severity of anterior accessory GSV (AAGSV) compared with GSV disease in patients presenting to dedicated outpatient vein centers.

Methods: Deidentified data were pulled from the American Vein & Lymphatic Society PRO Venous Registry for first and second patient encounters.

Objective: To prospectively compare disease severity in subjects with anterior accessory saphenous vein versus great saphenous vein incompetence with an incompetent saphenofemoral junction.

Methods: Data were^ collected from 241 subjects and 290 limbs over a six-month period. These subjects were categorized into three groups with primary venous reflux disease, namely anterior accessory saphenous vein, great saphenous vein, and control.

Objective: We assessed the incidence of venous thromboembolism following treatment of great saphenous insufficiency by endovenous thermal ablation or foam sclerotherapy using meta-analysis of published randomized controlled trials and case series.

Methods: Medline, Embase, Cochrane, and Clinical Trials Registry databases were searched from January 2000 through January 2013 for randomized controlled trials and large case series employing endovenous thermal ablation or foam sclerotherapy as a single modality for the treatment of great saphenous insufficiency, with concomitant postoperative duplex scanning. Pooled (stratified) incidence of venous thromboembolism with 95% confidence intervals was estimated using the DerSimonian–Laird procedure for random effects meta-analysis.
