The fibrinolytic activity of the venous wall was investigated by using Todd's technique' in 92 patients with different types of varicosis. A control group consisted of 19 patients with apparently normal superficial veins who had had a saphenectomy prior to an aortocoronary bypass operation. Fibrinolytic activity was mainly localized in the adventitia of varicose and normal veins. It significantly decreased in the distal regions of all types of varicosis. The highest fibrinolytic activity was detected in the proximal part of the varicose vena saphena magna and the lowest values were observed in the perforating and side branch veins of the calf. Fibrinolytic activity is higher (p <0.077) in the normal vena saphena magna than in the varicose vena saphena of the calf. Older patients show a loss of fibrinolytic activity in their vena saphena magna. Obese patients have less fibrinolytic activity in varicose calf veins than patients with normal weight do.

    Background: Despite adequate training in the surgical treatment of varicose veins, recurrence continues to be a problem and a burden to the vascular services. A major cause of recurrence is reported to be neo-vascularisation at the sapheno-femoral junction (SFJ). The aim of this study was to...

    Varicose veins alternate areas of phlebosclerosis and hypertrophy of the vein wall. In this study, samples of long saphenous veins obtained from patients submitted for aortocoronary saphenous vein graft or for surgical resection of varicose saphenous veins were examined.

    The meander phenomenon, the peculiar tortuosity of some vessels, is recognized within arteries as well as veins (fig. 1). It is observed in pathologic conditions such as in varicose veins, esophageal varices and in collaterals from obstructed arteries; it may also be observed in old ago in...

    Leg varices often show a peculiar and regular tortuosity, their course resembling the meander of river. The meanders of the great saphenous vein tend to start in certain regions, viz. at the levels of the union of a perforant with the superficial venous system. Knowledge of the underlying...
