[Study of venous distensibility using plethysmography with venous occlusion in post-phlebitic syndromes].

Venous distensibility has been studied in the cases of twelve patients presenting a post-phlebitic syndrome, compared with five patients with primary varicose veins. In the post-phlebitic syndromes we note far fewer symptoms of venous distensibility, whereas in the cases of varicose veins there is an increase of venous distensibility. Statistics of the delta V max. 50 and the symptoms of distensibility are given in a recapitulatory table, and a diagram.
