title: [Thromboembolic disease in pneumology. Value of mercury-gauge plethysmography with venous occlusion].
abstract: Mercury gauge plethysmography with venous occlusion (PJC) is an atraumatic procedure for the diagnosis of deep venous thrombosis (TVP) of the lower limbs: 103 patients were studied both by plethysmography and phlebography (the reference examination). 54 were hospitalised for a suspicion of pulmonary emboli (EP), 21 for clinical phlebitis and finally 28 subjects had the studies as part of a systematic work-up. 60 cases of TVP of the lower limbs were discovered: 47 were recent, 34 were proximal and 13 sural. The clinical examination failed to reveal these in 36% of cases; the phlebographic and PJC results were concordant for 75% of cases: PJC seemed particularly to be the technique of high sensibility for the early diagnosis of proximal TVP but of a lesser interest for the early diagnosis of peripheral TVP (sensibility 69%). This examination makes an important contribution: for the early diagnosis of hidden proximal TVP; for the diagnosis of EP in its deceptive forms where the presence of a peripheral embolic focus constitutes one weighing factor towards the diagnosis of peripheral thrombo-embolic disease (MIE); for the control of anti-coagulant therapy in the clinic where the local inflammatory process and the biology controlling the consumption of heparin are jointly observed and the study of venous drainage allows an appropriate decision to be made as to the cessation of anticoagulant therapy and minimises the risk of recurrence or avoiding postphlebitis disease by a prolonged treatment.
