FOLLOW-UP OF INFANTS WITH SINGLE UMBILICAL ARTERY

Of 39,773 white and black consecutive single births, 344 (0.9%) had single umbilical artery (SUA). The incidence was higher in whites (1.2%) than in blacks (0.5%). Despite high mortality in infants with SUA (14.0%) the incidence was still 0.7% among surviving infants. Associated malformations were present in 19 of 36 dead infants with SUA, or 52.8%, and in 11 of 266 SUA survivors, or 4.1%. Cardiovascular and genitourinary anomalies were not higher in dead infants with SUA compared to all dead malformed infants. A follow-up study of infants up to 4 years of age was undertaken, comparing 266 SUA survivors with 798 matched controls. Among malformations found in survivors, only inguinal hernia was significantly higher in SUA children compared to controls. The incidences of other specific abnormal conditions were not significantly different in the two groups. The mean values of body weight, body length, and head circumference at 4 months, 1 year, and 4 years of age, were almost equal in the two groups, as were the mental and motor scores at 8 months and the I.Q. at 4 years of age.

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.

Good Agreement

Aim. To determine agreement of cardiac anomalies between maternal fetal medicine (MFM) physicians and pediatric cardiologists (PC) in fetuses with single umbilical artery (SUA).Methods. A retrospective review of all fetuses with SUA between 1999 and 2008. Subjects were studied by MFM and PC, delivered at our institution, and had confirmation of SUA and cardiac anomaly by antenatal and neonatal PC follow-up. Subjects were divided into four groups: isolated SUA, SUA and isolated cardiac anomaly, SUA and multiple anomalies without heart anomalies, and SUA and multiple malformations including cardiac anomaly.Results. 39,942 cases were studied between 1999 and 2008. In 376 of 39,942 cases (0.94%), SUA was diagnosed. Only 182 (48.4%) met inclusion criteria. Cardiac anomalies were found in 21% (38/182). Agreement between MFM physicians and PC in all groups combined was 94% (171/182) (95% CI [89.2, 96.8]). MFM physicians overdiagnosed cardiac anomalies in 4.4% (8/182). MFM physicians and PC failed to antenatally diagnose cardiac anomaly in the same two cases.Conclusions. Good agreement was noted between MFM physicians and PC in our institution. Studies performed antenatally by MFM physicians and PC are less likely to uncover the entire spectrum of cardiac abnormalities and thus neonatal follow-up is suggested.

Future Management

The article by Froehlich and Fujikura1 on the prognosis of single umbilical artery is a much needed and highly informative addition to the literature. It presents a great deal of information and some important implications as to future management. We question the mortality rates quoted. They are given as percentages, and include stillbirths and neonatal deaths, i.e., perinatal mortality. The figure given as the general mortality rate is 3.8% or 38 per 1,000 births. Previous figures cited for perinatal mortality in the United States have varied from approximately 19 per 1,000 to approximately 26 per 1,000.2-4 We wonder how the figure of 38 per 1,000 was determined.
