| Abstract: | Rheoplethysmography with occlusion (RPO) is useful in the diagnosis of deep venous thrombosis. Bilateral phlebography with cavography performed afterwards as an emergency gives information as to the embolic potential of the thrombosis and orientates treatment towards surgical interruption of the inferior vena cava. In the C.H.U. at Grenoble 83 clips, 25 umbrella filters and 2 ligatures were placed on the inferior vena cava from 1974 to 1977. Prevention of pulmonary emboli was achieved in 99% cases with lower limb embolic foci. Follow-up by RPO and isotopic phlebography showed that the course of venous thrombosis of the lower limbs seemed to be unchanged by partial interruption of the inferior vena cava, provided that elastic stockings and adequate anticoagulant therapy adapted to venous haemodynamics are used. |
