Intimal Changes in Varicose Veins: An Ultrastructural Study.

Intimal changes in varicose veins: an ultrastructural study.

In order to study the structural changes in the intimal layer of varicose veins, we prospectively collected a total of 23 vein specimens from both the normal proximal thigh long saphenous (LSV) in 3 young trauma patients and from the unstripped proximal LSV near the sapheno-femoral junction and the distal calf blowouts in 10 primary varicose veins patients. Paraffin sections stained with hemato...

Tissue remodeling investigation in varicose veins

Although the etiology of varicose veins remains unknown, recent studies have focused on endothelial cell integrity and function because the endothelium regulates vessel tone and synthesizes many pro- and anti-inflammatory factors. The aim of this study was to investigate the evidence involving the endothelium in the development of varicose vein disease. In addition, tissue remodeling was invest...

Varicose Veins

Under normal circumstances, blood collected from superficial venous capillaries is directed upward and inward via one-way valves into superficial veins. These in turn drain via perforator veins, which pass through muscle fascia into deeper veins buried under the fascia. Leakage in a valve causes retrograde flow back into the vein. Unlike deep veins which are thick-walled and confined by fascia,...

varicose veins in male weavers; an epidemiological study

the prevalence of varicose veins was studied in 1742 male weavers in iran by completing a specially designed questionnaire and medical examination. to show the effect of occupation on the prevalence of the disease, similar study was conducted on a group of 1661 food- processing workers. the over- all prevalence of the disease in the weavers (26.12%) was significantly higher than the similar rat...
