PHLEBOGRAPHY IN THE LOCALIZATION OF INCOMPETENT COMMUNICATING VEINS IN PATIENTS WITH VARICOSE VEINS

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...

Thermographic Localization of Incompetent Perforating Veins

It is, howvver, difficult to explain on this basis how a patienmay resp6nd again once resistance has occurred (Figs. 1-4). For these reasons we believe that asparaginase should be used in combination with other drugs in the treatment of acute leukaemia. Although when used alone it does not produce complete remission in acute myeloid leukaemia, it still may have a part to play when used in combi...

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

Management of varicose veins.

Varicose veins are twisted, dilated veins most commonly located on the lower extremities. Risk factors include chronic cough, constipation, family history of venous disease, female sex, obesity, older age, pregnancy, and prolonged standing. The exact pathophysiology is debated, but it involves a genetic predisposition, incompetent valves, weakened vascular walls, and increased intravenous press...
