The obstetrical follow-up of patients with a severe hypofibrinogenemia requires a multidisciplinary collaboration because of potential maternal-fetal complications (recurrent miscarriages, intrauterine fetal demise, post-partum hemorrhage, thrombosis). We report the obstetrical management of a multiparous patient with a severe congenital hypofibrinogenemia associated with a platelet disorder (abnormal phospholipid externalization). A therapeutic strategy based on a biweekly administration of fibrinogen concentrates associated with enoxaparin and aspirin allowed the maintenance of pregnancy. But this last one got complicated by a placenta percreta requiring a salvage hysterectomy with an appropriate hemorrhage prophylaxis.
