[Management of pregnant women with deficiency of factor VII. Report of one case]. / Manejo de embarazada con deficiencia de factor VII. A propósito de un caso.

ABSTRACT

Tissue Factor-Factor VII complex is essential in coagulation activation. Congenital factor VII deficiency is a rare disorder that has an autosomal recessive inheritance. Clinical presentations are heterogeneous, ranging from asymptomatic carriers to severe bleeding phenotypes with factor VII replacement therapy requirements. Treatments options are plasma derived and recombinants FVII concentrates or fresh frozen plasma in case that first options are not available. In pregnancy factor VII levels increase in women with mild and moderate deficiencies but not in severe deficiency. The management of pregnant women with factor FVII deficiency must be done by a multidisciplinary team of hematologist, obstetrics and anesthetist and should be guided by the women bleeding history, the coagulations test, levels of factor FVII and rout of delivery. We present the case of a 31-year-old pregnant woman who, due to an alteration in prothrombin time, is diagnosed with Factor VII deficiency and its respective obstetric management.
