[Investigation of the thrombo-embolic disease by simultaneous lung scintigraphy and lower limb gamma-phlebography (author's transl)].

A venous thrombosis in the territory of the inferior vena cava and a possible embolus of the lung can be detected in one single examination by injecting 99 m Tc microagregates into a dorsal blood flow by this method, which associates radionuclide phlebography of the lower limbs and lung scanning, was carried out 140 times in 127 patients and resulted in the detection of 107 cases obliged us to investigate only one limb, gamma-phlebography appears to be a harmless procedure well suited to the study of the thrombo-embolic disease.
