Duplex ultrasonography and varicose veins

Duplex mapping of 2036 primary varicose veins.

OBJECTIVE To produce a comprehensive anatomical and hemodynamic ultrasound scan mapping of the whole limb in patients with primary varicose veins (VVs). DESIGN An analysis of venous duplex scans performed on patients referred for treatment of primary VVs. METHODS A total of 2036 limbs were evaluated, looking for the origin of VVs in the saphenous systems and in the perforating vein (PV) sys...

Recurrent varicose veins. Part 1: Evaluation utilizing duplex venous imaging.

There is the need to develop a universally accepted standard investigation for recurrent varicose veins. Duplex venous imaging offers a precise, non-invasive technique to make anatomic and hemodynamic diagnoses. A routine protocol of duplex imaging of recurrent varicose veins is described based on the known recurrent sources of reflux from deep to superficial veins. Results from this protocol i...

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,...

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...
