The Efficacy of Transarterial Embolization for Postpartum Hemorrhage Complicated with Disseminated Intravascular Coagulation: A Single-Center Experience

Indications for the use of transarterial embolization (TAE) for postpartum hemorrhage (PPH) have been established. However, the efficacy of TAE for PPH complicated by disseminated intravascular coagulation (DIC) remains controversial. In this study, we investigated the efficacy of TAE for PPH complicated by DIC. A database review was conducted to identify patients who were treated with TAE for PPH at our hospital. TAE was performed in 41 patients during the study period. Effective hemostasis was achieved in all cases, but additional procedures, such as re-embolization or hysterectomy, were required in five patients (12.2%). The typical causes of PPH included uterine atony (18 cases), placenta previa (15 cases), amniotic fluid embolism (DIC-type) (11 cases), and placenta accreta spectrum (10 cases). The mean blood loss was 3836 mL. The mean obstetrical DIC and the International Society on Thrombosis and Hemostasis DIC scores were 7.9 and 2.6, respectively. The efficacy of hemostasis was comparable between patients with and without DIC. However, the complete success rate of TAE was lower in patients with DIC as the condition worsened than that in non-DIC patients. Overall, TAE is effective as a minimally invasive treatment for PPH complicated by DIC.
