Sirenomelia is a very rare congenital anomaly. Type I is the mildest type, and the long bone structures are all normally present with only soft tissue fusion. We experienced a case of type I sirenomelia complicated by severe oligohydramnios. Because of severe oligohydramnios, ultrasonographic images were not very clear. The associated findings with sirenomelia (single umbilical artery and bilateral renal agenesis) were helpful for the prenatal diagnosis of this disease. Detailed sonographic examination of the fetus was thought to be necessary for the accurate prenatal diagnosis of sirenomelia.

The World

Sirenomelia, alternatively known as Mermaid Syndrome, is a very rare congenital deformity in which the legs are fused together, giving them the appearance of a mermaid's tail. This syndrome was originally stated by Rocheas and Palfya in 16th century. It occurs in about 1 in 100,000 live births. It is also associated with multiple anomalies like renal agenesis, ambiguous external genitalia, imperforate anus, blind intestinal loop and single umbilical artery. Occasionally double inferior Venacava, dextrocardia and angiomatous lumbosacral myelocystocele are reported as well. Most of the Sirenomelia come to an end as stillbirth. Only a few are born alive and survival beyond few hours after delivery is extremely rare. About 300 cases have been reported in the world literature so far.

Single Umbilical Artery

The case of prenatal ultrasound diagnosis of single umbilical artery aneurysm is presented. During ultrasound examination at 21 weeks of gestation several anomalies in the umbilical cord were detected: the umbilical right artery was missing and dilatation of the umbilical artery with a diameter 10 mm close to fetus. With colour Doppler and pulsed Doppler was demonstrated arterial turbulent flow in the aneurysm. Prenatal diagnosis of the single umbilical artery aneurysm was made. Other fetal measurements were normal. The diameter of the aneurysm increased throughout the pregnancy till 16 mm at 33 weeks of gestation. Cesarean section was performed at 34 weeks with baby weight 2150 g. The post-delivery examination of the umbilical cord confirmed the prenatal diagnosis. No chromosomal abnormalities were found. After six months the baby is alive and well.

A Prospective Study

ABSTRACT Objective Through a prospective study the incidence and neonatal results of patients with persistent right umbilical vein are evaluated. Materials and methods During the period between August 2009 and February 2011, 3,576 low-risk obstetric sonographies were performed by the same technician at four different centers of prenatal diagnosis. Persistent right umbilical vein was diagnosed during a customary ultrasound examination, in the abdominal transverse section used to measure abdominal perimeter. Patients were asked to bring their children several months after delivery for a clinical and sonographic evaluation. Results Persistent right umbilical vein was found in nine fetuses. In one case, it was associated with single umbilical artery. All fetuses had good growth and development. In some children, the postnatal sonography showed the gallbladder toward the left of falciform ligament. Conclusion The incidence of persistent right umbilical vein in this population was of 1:397. We did not find any association with severe malformations as mentioned in the first articles related to this topic. There was only one case with single umbilical artery. All newborns developed normally. The question is raised why, being this anomaly so frequent and obvious, it is not more often diagnosed. Gallbladder position in respect to falciform ligament is a finding to assess. How to cite this article Leal DB, Maggiolini M, Bianchi A.
