[Pulmonary embolism disclosing activated protein C resistance].
Resistance to the activation of protein C is a recently discovered constitutional anomaly of coagulation which is responsible for thromboembolic events in young subjects. We report a case in a 26 year old man who presented with pulmonary embolus. Laboratory data was characterised by an absence of any lengthening of the activated cephaline time after adding purified activated exogenous Protein C. The confirmation of this anomaly is provided by the evidence of a mutation Arg 506 to Gln of Factor 5. The outcome is favourable with treatment by Heparin then by anti-Vitamin K.
