To study the changes in central haemodynamics and the relationship between arterial blood pressure and the venous dynamics of the lower limbs in patients with venous insufficiency. Prospective haemodynamic study during postural changes in 14 patients with venous insufficiency with no other concomitant cardiovascular disease or disturbances in autonomic nervous system. Department of Cardiology and Angiology, University Hospital, Gent, Belgium. Fourteen patients with venous valve insufficiency in the lower limbs. Measurements of arterial blood pressure, heart rate, stroke volume and cardiac output were performed in the supine position after 30 min rest and 5, 15 and 30 min after standing and during the recovery. Venous pressure at the ankle and calf circumference were also measured. Changes in cardiac output and total peripheral vascular resistance in order to maintain blood pressure during postural changes. Arterial blood pressure was maintained constant owing to an increase in total peripheral vascular resistance despite a decrease in cardiac output. Venous pressure is also related to arterial blood pressure. The arterial and venous systems, even in venous insufficiency, are integrated to maintain blood pressure constant during postural changes.
