Recurrent and Persistent Varicose Veins

Pathogenesis and etiology of recurrent varicose veins.

BACKGROUND Recurrent varicose veins (RVV) occur in 13% to 65% of patients following treatment, and remain a debilitating and costly problem. RVV were initially thought largely to be due to inadequate intervention, however, more recently neovascularization and other factors have been implicated. This review aims to provide an overview of the current understanding of the etiology and pathogenesis...

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,...

Endovenous laser ablation (EVLA) to treat recurrent varicose veins.

OBJECTIVES This cohort study assesses the effectiveness and safety of endovenous laser ablation (EVLA) in the management of recurrent varicose veins (RVVS). METHOD 104 limbs (95 patients) undergoing EVLA for RVVS were grouped according to pattern of reflux. For patients with recurrent SFJ/great saphenous vein (GSV) (Group GR) and SPJ/small saphenous vein (SSV) (Group SR) varicosities ablation...

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...
