Fifty cases of placental lesions detected by sonography during the second half of pregnancy were pathologically investigated. Sonographic evaluation included the size of the lesion, its echogenicity on subsequent examinations and location in relation to the placental margin and umbilical cord insertions. Classical pathologic examination was performed after delivery to confirm the ultrasonographic findings. The echogenic pattern of these lesions was distinct from that of the rest of the placenta and the lesions were classified in two categories. The parenchymal lesions including 19 intervillous thrombosis, 14 caverns, 3 cases of hydatidiform changes, 2 infarcts, 1 septal cyst and one case of fibrin deposition and, the chorionic lesions including 5 subchorionic thrombosis, 3 cases of extrachorial placentas and 2 amniotic cysts. Therefore diagnostic ultrasound gives the clinician a unique opportunity to perform detailed examination of the placenta in vivo and can be an effective and non-invasive way to diagnose different types of lesions that are usually described in the post-partum by the pathologist.
对在妊娠后半期通过超声检查发现的50例胎盘病变进行了病理研究。超声评估包括病变的大小、后续检查时的回声特性以及相对于胎盘边缘和脐带插入点的位置。分娩后进行经典病理检查以证实超声检查结果。这些病变的回声模式与胎盘其他部分不同，病变分为两类。实质性病变包括19例绒毛间隙血栓形成、14例血窦、3例葡萄胎样改变、2例梗死、1例间隔囊肿和1例纤维蛋白沉积；绒毛膜病变包括5例绒毛膜下血栓形成、3例绒毛膜外胎盘和2例羊膜囊肿。因此，诊断性超声为临床医生提供了在体内对胎盘进行详细检查的独特机会，并且可以成为诊断不同类型病变的有效且非侵入性的方法，而这些病变通常是病理学家在产后描述的。
