Uterine Artery Embolization: A Case Report on Primary Postpartum Hemorrhage Management

When traditional therapies fail to control obstetric emergencies such as postpartum hemorrhage (PPH), uterine artery embolization (UAE) has become an essential intervention. This case study demonstrates the effective use of UAE in a 32-year-old patient who had an elective cesarean section and was experiencing refractory PPH. Despite initial attempts at controlling bleeding with uterotonic agents and surgical intervention, the hemorrhage persisted, necessitating packed red blood cell transfusion. A multidisciplinary team opted for UAE due to the patient's deteriorating condition. Gelatin sponge particles were utilized as embolic agents, resulting in the immediate cessation of uterine blood flow and the stabilization of the patient. This case underscores the importance of early detection, collaborative decision-making, and prompt intervention in managing PPH. UAE offers several advantages, including targeted vascular occlusion, rapid bleeding control, and the preservation of fertility. Further research and practice are warranted to optimize UAE techniques and enhance outcomes in obstetric emergencies. The primary cause of severe maternal morbidity and death is postpartum hemorrhage. For successful uterine artery embolization (UAE), prompt management is essential. UAE is widely acknowledged as a dependable and safe process.

Risk factors for postpartum hemorrhage in twin pregnancies with cesarean section

The rates of twin pregnancies and cesarean section have increased in recent years, and both of them are at high risks of postpartum hemorrhage (PPH). However, few studies have concentrated on the risks of PPH in twin pregnancies and cesarean deliveries. In this study, we aimed to identify the risk factors for PPH among twin-pregnant women with cesarean section. This was a retrospective observational study including 1,649 women with twin pregnancies delivered by cesarean section from 2016 to 2022 in the Second Affiliated Hospital of Wenzhou Medical University, China. The eligible women were divided into PPH group (n = 116) and non-PPH group (n = 1,533) according to the blood loss after delivery within 24 h. The baseline maternal and perinatal characteristics were compared between the two groups. Logistic regression analysis was conducted to identify the potential risk factors for PPH. We found nulliparity, assisted reproductive technology (ART) usage, preeclampsia or HELLP syndrome, placenta previa, placenta accreta and general anesthesia were more common in PPH group than non-PPH group (P < 0.05). Women in PPH group had higher maternal body mass index at delivery and higher combined birthweight of the twins than non-PPH group, but had lower parity (P < 0.05). Seven independent risk factors for PPH were identified after logistic regression analysis: ART usage (OR 2.354 95% CI 1.357-4.083, P = 0.002), preeclampsia or HELLP syndrome (OR 2.605, 95% CI 1.471-4.616, P = 0.001), placenta previa (OR 7.325, 95% CI 3.651-14.697, P < 0.001), placenta accreta (OR 6.296, 95% CI 1.316-30.12, P = 0.021), thrombocytopenia (OR 1.636, 95% CI 1.056-2.535, P = 0.027), general anesthesia (OR 2.394, 95% CI 1.223-4.686, P = 0.011), and combined birthweight (OR 1.00032, 95% CI 1.00005-1.00059, P = 0.020). Collectively, in women with twin pregnancies delivered by cesarean section, the use of ART, preeclampsia or HELLP syndrome, placenta previa, placenta accreta, thrombocytopenia, general anesthesia and the combined birthweight were identified as independent risk factors for PPH. More attention should be paid to women with these risk factors.
