Abstract：
Distinguishing between urinary bladder varices and retroplacental neovascularization in placenta accreta spectrum in high-risk patients with placental previa is a diagnostic challenge since they have similar appearances on prenatal ultrasound. Placenta accreta spectrum is associated with massive obstetric haemorrhage while the presence of urinary bladder varices in pregnancy poses a lower surgical risk. Since the clinical implications and management approach for both conditions are entirely different, false positive diagnoses have iatrogenic consequences. In this article, we share our experiences in differentiating these two phenomena on prenatal ultrasound supported by ultrasound and intraoperative images.
摘要：
在前置胎盘高危患者中，在胎盘植入频谱中区分膀胱静脉曲张和胎盘后新生血管是一项诊断挑战，因为它们在产前超声检查中具有相似的外观。胎盘植入谱与大量产科出血有关，而妊娠期膀胱静脉曲张的存在降低了手术风险。由于两种情况的临床意义和管理方法完全不同，假阳性诊断有医源性后果。在这篇文章中,我们分享了在超声和术中图像支持的产前超声上区分这两种现象的经验。
