The aim of reported case is to emphasise the importance of multidisciplinary approach in the management of pregnancy and delivery in the women with severe factor XII deficiency.

A woman with severe factor XII deficiency is successfully treated during her two pregnancies and deliveries. All coagulation tests are performed with standard Siemens reagents on the coagulometer Dade Behring BCS XP. A test for platelet aggregation for follow up of Aspirin treatment is performed on Siemens Innovance PFA-200 with standard Siemens collagen/epinephrin test cartridge.

During her two pregnancies, the woman with severe factor XII deficiency was regularly followed up in the Center for haemophilia in the Institute for Transfusion Medicine. According to coagulation tests in the first pregnancy she was treated with low molecular weight heparin in the postpartum period,  but in the second pregnancy it was necessary to be treated in the first and third trimester, as well as in the postpartum period.
