目的: 探讨早孕期美人鱼综合征的超声影像学及病理学特征。方法: 回顾性分析2011年5月至2021年8月包钢集团第三职工医院超声科产前超声诊断的8例“美人鱼综合征”胎儿超声声像图表现,并与胎儿标本尸检结果对比分析。结果: 8例 “美人鱼综合征”均经引产后随访证实,6例有详细的放射科或病理检查资料。产前诊断“美人鱼综合征”最直接和典型的声像图特征为双下肢融合,8例病例均为双下肢融合。其他伴发畸形包括皮肤水肿7例,单脐动脉5例,腹壁缺损2例,脊柱异常3例,羊水少3例,心脏畸形2例。结论: “美人鱼综合征”合并其他畸形的超声声像图表现复杂多样,以双下肢融合为特有的超声表现。产前超声检查对“美人鱼综合征”的确诊有重要价值,超声检查结果与放射科及病理科检查结果高度一致。
Objective: To investigate the ultrasonic imaging and pathological features of mermaid syndrome during early pregnancy. Methods: 8 cases of mermaid syndrome diagnosed by prenatal ultrasound in The Third Hospital of Baogang Group from May 2011 to August 2021 were retrospectively analyzed and compared with autopsy results of fetal specimens. Results: 8 cases of mermaid syndrome were confirmed by follow-up after induced labor, and 6 cases had detailed radiology or pathological examination data.The most direct and typical ultrasonographic feature of prenatal diagnosis of mermaid syndrome is double lower limb fusion, and 8 cases are double lower limb fusion.Other associated malformations include 7 cases of skin edema, 5 cases of single umbilical artery, 2 cases of abdominal wall defect, 3 cases of spinal column abnormality, 3 cases of oligohydramnios, and 2 cases of cardiac malformation. Conclusion: The ultrasonographic manifestations of mermaid syndrome complicated with other malformations are complex and varied, and the fusion of lower limbs is the unique ultrasonographic manifestation.Prenatal ultrasound examination is of great value in the diagnosis of mermaid syndrome, and the results of ultrasound examination are highly consistent with those of radiology department and pathology department.
