title: [Physical capacity and some determining factors in the patient with the postphlebitic syndrome].
abstract: 40 limbs from normal persons and 32 limbs from patients with postphlebitic syndrome were studied. The latter group was classified according to the phlebography in partial and total recanalized postphlebitic groups. The research was carried out with a strain gauge plethysmograph and an ergometric bicycle. The patients showed the greater values of the venous volume, the maximal venous outflow and the rate of venous refilling, specially, the patients with total recanalized postphlebitic syndrome; this suggest a greater degree of venous valve insufficiency and a loss of the viscoelastic properties of venous vascular wall. The peripheral resistance was greater in the postphlebitic groups and it suggests a higher sympathetic nervous tone. The physical working capacity was lower in the postphlebitic patients and no relation was observed between it and the plethysmographic parameters.
