  • Title: [Alterations in coagulation and fibrinolytic system in abruptio placentae (author's transl)].
    Author: Saito H.
    Journal: Nihon Sanka Fujinka Gakkai Zasshi; 1982 Apr; 34(4):529-37. PubMed ID: 7069257.
    Abstract:
    Abruptio placentae tends to be accompanied by abnormal coagulation and fibrinolysis, and is known as high risk pregnancy allowing both mother and fetal lives to endanger. Blood coagulation and fibrinolytic system in abruptio placentae, in particular, sequential changes around its onset have been remained unclarified despite the progress in hematology. This permits an irregular therapeutical process for its acute clinical manifestation. In this study, observation was made of the changes of coagulation and fibrinolytic system mainly in relation to delivery, and hemorrhagic diathesis in abruptio placentae was studied. The results obtained are as follows. The studied patients were 14 cases classified into 8 multipara, 10 toxemia of pregnancy, 6 cesarean section, 11 intrauterine fetal death, and 8 complicated disseminated intravascular coagulation respectively. A moderate type demonstrating an increased serum FDP with retarded ESR and lowering in fibrinogen level were observed, but those abnormalities recovered to normal by 3 days after delivery. In serious case, observations also were made of marked decrease of fibrinogen, prolonged PT and PTT, high concentrations of serum and urinary FDP, lowering in levels of coagulation factors, attenuated platelet counts, retarded ESR, and inhibition of platelet aggregation along with thrombelastgram that showed thrombocytopenic type. All of those anomalies tended to be improved following delivery.
