Abstract

Severe obstetric hemorrhage is a leading cause of maternal mortality and morbidity worldwide. Major hemorrhage in the antepartum period presents potential risks for both the mother and the fetus. Similarly, postpartum hemorrhage (PPH) accounts for up to a quarter of maternal deaths worldwide. Potential causes of severe antepartum hemorrhage that radiologists should be familiar with include placental abruption, placenta previa, placenta accreta spectrum disorders, and vasa previa. Common causes of PPH that the authors discuss include uterine atony, puerperal genital hematomas, uterine rupture and dehiscence, retained products of conception, and vascular anomalies. Bleeding complications unique to or most frequently encountered after cesarean delivery are also enumerated, including entities such as bladder flap hematomas, rectus sheath and subfascial hemorrhage, and infectious complications of endometritis and uterine dehiscence. ^©RSNA, 2024 Test Your Knowledge questions for this article are available in the supplemental material.

产前和产后出血的成像。

产科大出血是全球孕产妇死亡和发病的主要原因。产前大出血对产妇和胎儿都有潜在风险。同样，产后出血（PPH）占全球孕产妇死亡人数的四分之一。放射科医生应该熟悉的严重产前出血的潜在原因包括胎盘早剥、前置胎盘、胎盘早剥频谱紊乱和前置胎盘血管。作者讨论的 PPH 常见原因包括子宫失弛缓、产褥期生殖器血肿、子宫破裂和开裂、受孕产物滞留以及血管异常。此外，还列举了剖宫产后特有或最常遇到的出血并发症，包括膀胱瓣血肿、直肠鞘和筋膜下出血以及子宫内膜炎和子宫开裂的感染性并发症。©RSNA，2024 关于本文的 "知识测试 "问题可在补充材料中找到。请参阅本期 Javitt 和 Madrazo 的特邀评论。

期刊介绍： Launched by the Radiological Society of North America (RSNA) in 1981, RadioGraphics is one of the premier education journals in diagnostic radiology. Each bimonthly issue features 15–20 practice-focused articles spanning the full spectrum of radiologic subspecialties and addressing topics such as diagnostic imaging techniques, imaging features of a disease or group of diseases, radiologic-pathologic correlation, practice policy and quality initiatives, imaging physics, informatics, and lifelong learning. A special issue, a monograph focused on a single subspecialty or on a crossover topic of interest to multiple subspecialties, is published each October. Each issue offers more than a dozen opportunities to earn continuing medical education credits that qualify for AMA PRA Category 1 CreditTM and all online activities can be applied toward the ABR MOC Self-Assessment Requirement.
