Chronic venous disease is caused by chronic venous insufficiency (CVI), which results in significant symptoms such as venous ulcers, ankle eczema, leg swelling, etc. Venous valve incompetence is a major cause of CVI. When the valves of veins in the leg become incompetent (i.e., do not close properly), blood is able to flow backwards (i.e., reflux), which results in blood pooling in the lower extremities, distal venous hypertension, and CVI. Current clinical therapies, such as surgical venous valve reconstruction and bioprosthetic venous valve replacement, are highly invasive and only moderately successful...

The article describes the medical approach of a frequent pathology, chronic venous insufficiency. Chronic venous insufficiency requires early diagnosis as well as an evaluation of the associated risk factors; also, patients need to understand the disease and its treatment, and to become compliant with all their physician's recommendations. Importantly, the physician should correctly evaluate the disease and decide the best option for the patient. These days, it is crucial that the patient benefits from optimal treatment choice in order to prevent complications...

Exercise intervention for individuals with chronic venous insufficiency (CVI) and venous leg ulcers (VLUs) is recommended to improve function of the calf muscle pump (CMP). A systematic review with meta-analysis was conducted to measure the effects of exercise (including function of the CMP, ankle strength, range of motion [ROM], and healing rates) for VLUs. Four (4) databases (Cumulative Index to Nursing and Applied Health Literature, 1981; MEDLINE, 1964; Scopus, 1966; and EMBASE, 1947) were searched for relevant articles from the date of index inception to January 2016...

The post thrombotic syndrome (PTS) refers to clinical manifestations of chronic venous insufficiency (CVI) following a deep-vein thrombosis (DVT). PTS is the most frequent complication of DVT, which develops in 20 to 50% of cases after proximal DVT and is severe in 5-10% of cases. The reported prevalence of PTS differs widely among studies because of differences in study populations, tools used to assess PTS, and time interval between acute DVT and PTS assessment. The two most important predictors of PTS are extensive proximal character of DVT and previous ipsilateral DVT...

Venous valve incompetence has been implicated in diseases ranging from chronic venous insufficiency (CVI) to intracranial venous hypertension. However, while the mechanical properties of venous valve leaflet tissues are central to CVI biomechanics and mechanobiology, neither stress-strain curves nor tangent moduli have been reported. Here, equibiaxial tensile mechanical tests were conducted to assess the tangent modulus, strength and anisotropy of venous valve leaflet tissues from bovine jugular veins. Valvular tissues were stretched to 60% strain in both the circumferential and radial directions, and leaflet tissue stress-strain curves were generated for proximal and distal valves (i...

Prolonged standing or sitting is one of the factors for chronic venous insufficiency. The aim of the study was to determine the impact of static load of the lower limbs on the functioning of the venous system. The study included 10 healthy young participants, with no peripheral venous disease. All participants took part in examinations in two variants: variant 1, sitting for 20 min with the lower limbs bent in the knee joints at 90°; variant 2, standing for 20 min with no additional load. Before and after each test, the venous refilling time (VRT) was determined using photoplethysmography...

Venous leg ulceration (VLU) is a chronic condition associated with chronic venous insufficiency (CVI), where the most frequent complication is recurrence of ulceration after healing. Traditionally, graduated compression therapy has been shown to increase healing rates and also to reduce recurrence of VLU. Graduated compression occurs because the circumference of the limb is narrower at the ankle, thereby producing a higher pressure than at the calf, which is wider, creating a lower pressure. This phenomenon is explained by the principle known as Laplace's Law...

[Purpose] This study was aimed to analyse the effects of short-term use of compression stockings (CS) on symptoms and QoL in patients with Chronic Venous Insufficiency (CVI). [Subjects and Methods] Based on the CEAP classification C2 and C3, 117 patients with CVI were enrolled in this study. The participants were divided into two groups. The control group refused to use CS, however, was advised to do exercises and take skin care whereas the CS group used CS and performed exercise. The data were collected by using Nottingham Health Profile (NHP), Venous Insufficiency Epidemiological and Economic Study (VEINES-QoL/Sym) and Beck Depression Inventory (BDI) at baseline and after four weeks of treatment and compared within and in between groups...
