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...

OBJECTIVE: Pelvic venous incompetence can cause symptomatic varicose veins in the perineum, buttock, and thigh. Presentation, symptom severity, and response to treatment of pelvic source varicose veins are not well defined. Currently available tools to measure the severity of lower extremity venous disease and its effects on quality of life may be inadequate to assess disease severity in these patients. The purpose of this study was to evaluate the histories, demographics, and clinical presentations of women with pelvic source varicose veins and to compare these data to a population of women with nonpelvic source varicose veins...

Objective Ultrasound-guided foam sclerotherapy (UGFS) - one of the most frequently recommended methods for treating great saphenous vein incompetence - is easy and inexpensive. However, it achieves a lower occlusion rate compared to endovenous thermal ablation. The application of UGFS to pre-terminal great saphenous vein interruption, eliminating the saphenous stem wash out effect, enhances the short-term occlusion rate. This study explores the results of this technique at 12 months. Method Thirty great saphenous veins (28 patients) with junction incompetence, with calibres >6 mm and >30 cm reflux stem length were submitted to echo-guided pre-terminal great saphenous vein interruption and foam great saphenous vein occlusion...

The veins of the lower extremity are equipped with efficient wall, contractile vascular smooth muscle (VSM), and competent valves in order to withstand the high venous hydrostatic pressure in the lower limb and allow unidirectional movement of deoxygenated blood toward the heart. The vein wall structure and function are in part regulated by matrix metalloproteinases (MMPs). MMPs are zinc-dependent endopeptidases that are secreted as inactive pro-MMPs by different cells in the venous wall including fibroblasts, VSM, and leukocytes...

BACKGROUND: Varicose veins, a common problem with effects on quality of life, account for a significant cost burden on the health care system. Despite their prevalence, the pathophysiologic mechanism of varicose veins remains incompletely understood. The fundamental issue is whether venous hypertension and valvular incompetence precede and influence the development of vein wall changes or whether the reverse is true. METHODS: We have reviewed the English-language literature to provide the most current understanding of the hemodynamic and cellular and molecular processes that underlie the development of varicose veins...

This open registry aimed to evaluate the clinical evolution of postpartum varicose veins (VVs), in healthy women after the second pregnancy, how these veins regain shape and competence, and possible treatments. The registry included two groups of women: (1) those who used elastic compression stockings, and (2) who used an oral venotonic agent (Pycnogenol, 100 mg/d). A total of 12 evaluation targets were established. Minor symptoms were scored in an analogue scale line. A visual analogue scale line evaluated the overall satisfaction relative to elastic compression or Pycnogenol...

Right-ventricular outflow tract (RVOT) endocarditis is a very rare presentation of right-sided infective endocarditis (RSIE) by brucellosis. RSIE occurs most commonly in immune-suppressed cases and illicit drug abuser. The patients with RSIE and an incompetent immune system usually have a prosthetic foreign body in blood circulation such as catheter, pacemakers, or central venous lines and may be accompanied with tricuspid or pulmonary valve dysfunction. The most common site for RSIE is the tricuspid valve...

Background Recurrent varicose veins occur up to 80% of procedures. The sapheno-femoral junction can be involved in more than 50% of cases. A detailed pathophysiological explanation of the phenomenon is still missing. The aim of the present work is to evaluate the role of femoral vein incompetence as risk factor for sapheno-femoral junction recurrence. Methods Three-hundred-eighty-one patients presenting an incompetent great saphenous vein system and eventually also an incompetent femoral tract (C2-6EpAsdPr) underwent a great saphenous vein high ligation with flush ligation also of the incompetent tributaries along the leg, sparing the saphenous trunk...

Incompetent superficial veins are the most common cause of lower extremity superficial venous reflux and varicose veins; however, incompetent or insufficient perforator veins are the most common cause of recurrent varicose veins after treatment, often unrecognized. Perforator vein insufficiency can result in pain, skin changes, and skin ulcers, and often merit intervention. Minimally invasive treatments have replaced traditional surgical treatments for incompetent perforator veins. Current minimally invasive treatment options include ultrasound guided sclerotherapy (USGS) and endovascular thermal ablation (EVTA) with either laser or radiofrequency energy sources...
