Cyclopia is a rare fetal malformation characterized by a single palpebral fissure and a proboscis associated with severe brain malformations. Approximately 1.05 in 100,000 births including stillbirths are identified as cyclopean. The prevalence is about one in 11,000 to 20,000 in live births and one in 250 during embryogenesis.
A 30-year-old Indian woman of Asian origin, sixth gravida, was referred to the labor room of our hospital. There were no ultrasound examinations performed during this pregnancy as our patient had not received regular antenatal care. We found out that the head of her baby was already outside the vulva but the remaining parts of the baby were not yet delivered. Further examination was carried out and a diagnosis of shoulder dystocia with intrauterine fetal demise was made. A stillborn baby boy of 3.5 kg was delivered using McRoberts' maneuver. The baby was suspected of having features of cyclopia and this was later confirmed by autopsy and anatomic correlation. The mother had a cervical tear which extended into the lower segment of her uterus, thus leading to the rupture of her uterus. There was a massive broad ligament hematoma on the left side of her uterus. A total abdominal hysterectomy was carried out.
Prenatal diagnosis by ultrasound examination might help in detecting cyclopia and preventing complications associated with this condition. However, in developing countries where women do not receive regular antenatal care and do not undergo prenatal diagnosis, such cases will go undetected. In our case report, the occurrence of shoulder dystocia could be coincidental, as no risk factors were previously noted.
独眼畸形是一种罕见的胎儿畸形,其特征为单一睑裂和与严重脑畸形相关的长鼻。每100,000例出生(包括死产)中约有1.05例被诊断为独眼畸形。活产中的患病率约为11,000至20,000分之一,胚胎发育期间为250分之一。
一名30岁的亚洲裔印度女性,第六次妊娠,被转诊至我院产房。由于该患者未接受定期产前检查,此次妊娠期间未进行超声检查。我们发现她的婴儿头部已露出外阴,但婴儿的其余部分尚未娩出。进一步检查后诊断为肩难产伴宫内胎儿死亡。采用麦罗伯茨手法娩出一名体重3.5千克的死产男婴。该婴儿疑似患有独眼畸形特征,后来经尸检和解剖学关联得以证实。母亲宫颈撕裂并延伸至子宫下段,导致子宫破裂。子宫左侧有巨大阔韧带血肿。遂行全腹子宫切除术。
超声检查进行产前诊断可能有助于检测独眼畸形并预防与此病症相关的并发症。然而,在妇女未接受定期产前检查且未进行产前诊断的发展中国家,此类病例将无法被发现。在我们的病例报告中,肩难产的发生可能是巧合,因为之前未发现危险因素。
