Abstract

The risk of postpartum hemorrhage (PPH) remains substantial even in pregnant women with a resolved low-lying placenta. Additionally, some cases of postpartum retained products of conception (RPOC) have been associated with placental complications during delivery, while the majority lack an identifiable cause or risk factor. This report highlights an abnormal vessel directed toward the lower uterine segment, identified as the cause of PPH and subsequent RPOC following the resolution of a low-lying placenta. Although a low-lying placenta observed in the second trimester resolves in most cases, it necessitates heightened vigilance regarding the risk of PPH and subsequent vascular RPOC.

子宫血管作为产后出血的原因和低胎盘溶解后受孕血管残留产物。

产后出血（PPH）的风险仍然是实质性的，即使在孕妇解决低胎盘。此外，一些产后受孕残留物（RPOC）的病例与分娩期间的胎盘并发症有关，而大多数病例缺乏可识别的原因或危险因素。本报告强调了指向子宫下段的异常血管，确定为PPH和随后的低胎盘分解后RPOC的原因。虽然在大多数情况下，在妊娠中期观察到的低胎盘会消退，但需要对PPH和随后的血管RPOC的风险提高警惕。

期刊介绍： The Journal of Clinical Ultrasound (JCU) is an international journal dedicated to the worldwide dissemination of scientific information on diagnostic and therapeutic applications of medical sonography. The scope of the journal includes--but is not limited to--the following areas: sonography of the gastrointestinal tract, genitourinary tract, vascular system, nervous system, head and neck, chest, breast, musculoskeletal system, and other superficial structures; Doppler applications; obstetric and pediatric applications; and interventional sonography. Studies comparing sonography with other imaging modalities are encouraged, as are studies evaluating the economic impact of sonography. Also within the journal''s scope are innovations and improvements in instrumentation and examination techniques and the use of contrast agents. JCU publishes original research articles, case reports, pictorial essays, technical notes, and letters to the editor. The journal is also dedicated to being an educational resource for its readers, through the publication of review articles and various scientific contributions from members of the editorial board and other world-renowned experts in sonography.
