This study aimed at clarifying the changes in treatments for primary varicose veins in Japan. A questionnaire was mailed to the members of the Japanese Society of Phlebology. The contents of the survey covered the treatment and treatment strategy of varicose vein cases in 2013. The results were examined and compared with the results of previous surveys conducted by the aforesaid society in 1998, 2004 and 2009. Of 36078 patients, 43958 limbs were reported from 201 institutions. Saphenous type was the most common type of varicose veins that developed in patients aged 70-79 years. The C4-6 cases according to the Clinical-Etiology-Anatomy-Pathophysiology (CEAP) classification occurred significantly more in males than in females (p <0.01). For the treatments of saphenous type and of segment type (dilatation of peripheral branch), endovenous laser ablation (EVLA) was performed most frequently (51%), while the frequency of stripping and of high ligation decreased. EVLA was performed with tumescent local anesthesia, which required one day of hospitalization. In our study, the number of patients with varicose veins increased especially in the elderly. Surgical treatments were selected for a number of patients, and EVLA was the most commonly adopted method of treatment in Japan. (This article is a translation of Jpn J Phlebol 2016: 27; 249-57.).

Background: Varicose veins (VVs) are a common chronic venous disorder with a complex pathophysiology involving immune dysregulation, inflammation, and genetic predisposition. This study aims to identify immune-related causal factors in the pathogenesis of VVs using Mendelian randomization (MR).
Methods: A two-sample MR analysis was conducted to assess the causal relationships between immune cell phenotypes and VVs.

Aim: This study aimed to develop a web-based machine learning (ML) model to predict the lifetime likelihood of developing varicose veins using global disease prevalence data.
Methods: We utilized data from a systematic review, registered under PROSPERO (CRD42021279513), which included 81 studies on varicose vein prevalence across various geographic regions. The data used to build the ML model included disease prevalence as the outcome (%), along with the following predictors: mean age, gender distribution (%), mean body mass index (BMI) of the study cohort, and the mean gravity field of the study region (mGal), representing variations in Earth's underground mass distribution that influence blood and fluid redistribution in the human body, affecting disease prevalence.

Our objective was to assess the effect of Venous Leg Ulcer (VLU) healing on Quality of Life (QoL) in patients undergoing compression therapy. This non-randomized, quasi-experimental, and observational study involved patients with VLU. A convenience sample of individuals receiving services was followed for at least one year while undergoing compression therapy.

Endovenous surgery in the treatment of varicose veins generally consists of laser or radiofrequency ablation (RFA) as endovenous thermal ablation (ETA) with a phlebectomy or foam sclerotherapy of tributary varicose veins to improve symptomatic or cosmetic problems. Nevertheless, the efficacy of their concomitant treatments is still controversial for a decade. In the guidelines of the Japanese Society of Phlebology, concomitant phlebectomy of tributary varicose veins with ETA is described that it is not recommended officially.

The glycocalyx is an essential structural and functional component of endothelial cells. Extensive hemodynamic changes cause endothelial glycocalyx disruption and vascular dysfunction, leading to multiple arterial and venous disorders. Chronic venous disease (CVD) is a common disorder of the lower extremities with major health and socio-economic implications, but complex pathophysiology.
