Background: Chronic venous insufficiency (CVI) affecting the deep venous system is most often caused by postthrombotic syndrome (PTS), which leads to reflux, blood pooling, and venous hypertension in the lower extremities. Researchers have sought to restore deep valvular competence, with numerous attempts at primary repair and valve replacement yielding limited results. This article presents the mid-term outcomes (3 years) of the first-in-human study of the bioprosthetic VenoValve surgically implanted in patients with CVI.

Orthostatic hypotension (OH) is a common cardiovascular disorder with high prevalence in the elderly. Concomitant venous return impairment may worsen the autonomic response and accentuate the symptoms. We detailed a patient with severe OH, prominent varicosities, and hemosiderin deposition in lower limbs.

Article Synopsis
  • * A systematic review of studies on veno-active drugs (VADs) revealed that only specific treatments like micronized purified flavonoid fraction (MPFF), aminaphthone, and low-dose diosmin showed statistically significant improvements in HRQoL compared to placebo.
  • * The research included data from various sources, highlighting a discrepancy between patient and physician perceptions regarding the impact of CVD, where physicians often underestimate the emotional and physical toll on patients.

Introduction: VEIN STEP was conducted to collect international data on the management of chronic venous disease (CVD) and to assess the effectiveness of conservative treatments for the relief of CVD signs and symptoms.

Methods: This international, observational, prospective, longitudinal, cohort study recruited adult outpatients consulting for symptomatic CVD. The primary objective was the effectiveness of conservative treatments on symptoms, signs and quality of life in a real-life setting assessed using a range of patient-reported outcome measures: 10-cm Visual Analog and Patient Global Impression of Change scales for symptoms; Venous Clinical Severity Score for physician assessment of signs; and 14-item ChronIc Venous Insufficiency Questionnaire (CIVIQ-14) for quality of life.

Article Synopsis
  • Venous Ulcers (VU) are a common type of leg ulcer caused by problems like venous hypertension or valve failure, making up 60-80% of all cases.
  • While traditional treatment methods that target the underlying causes are standard, about 30% of these ulcers don't heal with those approaches, leading to the exploration of growth factors as additional treatments.
  • A review of various studies from 2002 to 2022 found that topical, intralesional, and perilesional applications of growth factors could be effective, with the latter suggesting a promising alternative treatment for venous ulcers.

Evidence-based medicine favours randomised controlled trials to limit bias and establish the effects of a treatment with statistical rigour. However, the controlled conditions and careful patient selection of randomised trials may produce results that cannot be generalised to a more diverse patient population in clinical practice. Therefore, there is growing recognition of the importance of supplementing randomised trial data with real-world evidence.

Published scientific evidence demonstrate the current spread of healthcare misinformation in the most popular social networks and unofficial communication channels. Up to 40% of the medical websites were identified reporting inappropriate information, moreover being shared more than 450,000 times in a 5-year-time frame. The phenomenon is particularly spread in infective diseases medicine, oncology and cardiovascular medicine.

Background: Sclerotherapy is a non-invasive procedure commonly used to treat superficial venous disease, vascular malformations and other ectatic vascular lesions. While extremely rare, sclerotherapy may be complicated by serious adverse events.

Objectives: To categorise contraindications to sclerotherapy based on the available scientific evidence.

Introduction: Venous leg ulcers (VLUs) are the final stage of chronic venous insufficiency. This study aims to characterize the association between cardiovascular diseases and VLU.

Methods: A multicentric case-control study analyzed 17,788 patients between 2015 and 2020.

Objective: Two-year follow-up results from a first-in-human study of patients implanted with the VenoValve are evaluated for supporting the long-term clinical safety and performance of the device.

Background: Chronic Venous Insufficiency (CVI) involves improper functioning of lower limb vein valves and inability of these valves to move blood back towards the heart. CVI symptoms include swelling, varicose veins, pain, and leg ulcers.

Article Synopsis
  • A thorough pulse examination can effectively assess blood flow to the legs, but modern imaging tests are overshadowing traditional methods in medical training.
  • The reliance on advanced imaging techniques may lead to unnecessary expenses and tests for evaluating blood flow issues.
  • This report aims to teach newer doctors and remind seasoned ones about the importance of mastering precise pulse examinations in physical assessments.

Pelvic venous insufficiency (PVI) is common in women but has been rarely diagnosed in men. The clinical manifestations include varicocele and pelvic disturbances; however, we were unable to find a previous description of painful ejaculation as a symptom of PVI. We present the case of a 36-year-old man with a 7-year history of severe sharp ejaculatory pain.

This research compared patient and physician perceptions of quality of life (QoL) in C0-4 chronic venous disease (CVD). Qualitative standardized phone interviews were conducted with 100 patients and 60 specialists from Brazil, China, the Czech Republic, Italy and Russia. In addition to the impact of physical symptoms on QoL, patient interviews revealed a high aesthetic and emotional burden of C0-4 CVD that contributes to social isolation and affects relationships.
