[Occlusive rheoplethysmography in the diagnosis, surveillance and evaluation of the sequela of phlebitis].
Occlusive rheoplethysmography (RPO) constitutes a new method of quantitative tetrapolar rheography. It enables us to assess peripheral venous function by measuring distensibility (symbol of influx = IR greater than 0.6, and of drainage = IV greater than 0.7), and flow (symbol of the drainage flow = IDV greater than 0.5). Deep venous thrombosis in the receptor trunk of the popliteal vein and vena cava reduces the IDB (obstructive syndrome). Isolated thrombosis of the tibial vein modifies only the distensibility (restrictive syndrome). RPO is extremely reliable in the diagnosis of acute venous thrombosis of the receptor trunk, as well as in the diagnoses of tibial thromboses, and so it facilitates the recognition of indicants for phlebography. RPO constitutes a simple, portable, rapid, economical and totally objective examination; its use in the observation of the efficiency of treatments as well as in the quantitative assessment of phlebitic after-effects means that it makes a valuable contribution to the management of venous disorders.
