[Various hemodynamic characteristics of the venous circulation of the lower limbs in the patient with recurrent varices]. / Estudio de algunas características hemodinámicas de la circulación venosa de los miembros inferiores en el paciente con varices recidivantes.

The present study included a control group of 30 lower limbs without venous disease, a group of 30 lower limbs with primary varicosities and a group of 30 lower limbs with recidivant varicosities. Technics used for diagnosis were: Doppler ultrasonography and "strain-gauge" plethysmography. We found a relentisement of the venous flow on patients with recidivant varicosities. No differences on basal and maximal flow between primary and recidivant varicosities have been reported. It seems that no disturbances on the arterial flow are present. It seems also that patients with recidivant varicosities have no special incidence of valvular failure.
