LIGHT-REFLECTION RHEOGRAPHY AND ACUTE DEEP-VEIN THROMBOSIS

The authors examined 47 subjects affected by acute phlebothrombosis of the lower limbs by means of light-reflection-rheography (LRR). The di agnosis was based on the results of clinical, Doppler, and duplex scan ner evaluations. The results were compared with those obtained in 30 h ealthy subjects (control group).The LRR examinations were performed by two methods: the one consisting of a passive execution of postural mo vements of the limb, the other using the technique of plethysmographic venous occlusion. The pathological LRR curves were characteristic for each type of disease and for the site of thrombosis and were differen t from the normal ones. The results obtained show the usefulness of th e method and it potential in studying the collateral circulation and t he effects of different therapies.
