A Case of Congenital Duodenal Atresia Diagnosed by Prenatal Ultrasonography / 대한주산의학회잡지

Congenital duodenal atresia is the most common cause of perinatal intestinal obstruction. Abdominal distension and projectile vomiting are the specific symptoms of neonatal gastro-intestinal obstruction. The incidence of duodenal atresia is between 1 in 2,710 and 1 in 10,000 live births.1 Most cases are thought to be failure of recanalization of the duodenal lumen during embryonic period.2 Duodenal atresia is associated with a high incidence of other associational anomalies, including esophageal atresia, biliary atresia, congenital heart disease and vertebral anomalies. Prenatal diagnosis, the ealry operation and the facotrs such as prematurity, combined abnormalities, nutirtion have a significant influence on complication and mortality.3,4 We report a case of congenital duodenal atresia diagnosed by ultrasonography prenatally in Andong general hostpital at 26 gestational weeks and operated the 7th day of cesarean section in Yeungnam university hospital with a brief review of literature.

A Case of Varix of the Fetal Intra-Abdominal Umbilical Vein and Review of the Literature / 대한산부인과학회잡지

Varix of the intraabdominal portion of the fetal umbilical vein is a rare entity. We present a case of varix of the intrafetal umbilical vein diagnosed by routine prenatal ultrasonography at 35 weeks of gestation. Color Doppler examination of the abnormal umbilical vein demonstrated turbulent flow through 23-mm diameter cystic dilatation of the fetal intra-abdominal umbilical vein consistent with a varix. No other sonographic abnormalities were detected, and a healthy infant was delivered at term.
