[Allergy to heparin. Particular problems in the pregnant woman]

Abstract

Oral anti-coagulants are always contra-indicated for pregnant women. Only anti-coagulants of the types of heparin or its derivatives may be used. However, some patients have an allergy to Heparin. In this article the correct action to take both for diagnosis and prevention is studied. We present 2 observations of heparin-allergic pregnant women with, in the first case a tentative addiction to heparin which created a check and in the second case there was success in a second pregnancy with low-molecular weight heparin.
