[Site of phlebographically determined venous changes in postphlebitic syndrome with varicose ulcer]
Abstract:
In 207 legs with venous leg ulcers and postthrombotic syndrome proved by phlebography, the frequency of involvement of the 4 levels of deep venous system was assessed. Level A: deep veins of the lower leg. Level B: poplieal vein and gastrocranial veins. Level C: femoral veins. Level D: iliac veins. Our investigations showed that in 35% damages of the deep veins only in level A (lower leg) were responsible for venous ulcer. In cases with combinations of levels, Level A in 95% also was involved. One can say that postthrombotic leg ulcer correlates above all with the pathomorphological alterations of the lower leg veins.
