Objective To determine, by evaluation of histological slides, images and descriptions of early (second-trimester) placenta accreta (EPA) and placental implantation in cases of Cesarean scar pregnancy (CSP)

We managed two pregnancies in a woman with congenital afibrinogenemia with increasing amounts of cryoprecipitate to achieve a pre-infusion fibrinogen level of 60 mg/dL. The first pregnancy resulted in placental abruption at 36 weeks, in spite of recent cryoprecipitate infusion. Both placentas showed infarction. Post-partum ovarian and renal vein thromboses complicated the second pregnancy. Mean FVIII (344%) and vWF Antigen (323%) were elevated prior to cryoprecipitate infusion, with mean post-infusion levels of 367% and 363%. The clearance of fibrinogen after cryoprecipitate infusion increased during the course of pregnancy. A paradoxical prothrombotic state with embolization may play a role in the observed complications of pregnancy. Am.
