[Congenital blood coagulation factor X deficiency. Successful result of the use prothrombin concentrated complex in the control of ++cesarean section hemorrhage in 2 pregnancies].
There is little experience in the prevention of the severe hemorrhagic diathesis of factor X coagulation factor deficiency, before surgical procedures. A female with congenital deficiency of factor X that received prothrombin complex concentrates that contained 1.000 IU of factor X (16.7 U/l Kg BW) immediately prior to a cesarean section in two occasions, is reported. Factor X concentration rose from 1 to 25% in the first occasion and from 10 to 63% in the second. In both episodes, factor X decreased in the first 24 h of the postoperative period and required new infusions of prothrombin complex concentrates. No episodes of abnormal bleeding were observed. It is concluded that the infusion of prothrombin complex concentrates prevents the hemorrhagic diathesis of factor X deficiency, despite its modest increase in plasma. A initial infusion of 1.000 UI of factor X (16-20 IU/Kg BW), followed by 500 IU (8-10 IU/Kg) every 24 hours is suggested for an adequate management of this condition.
