Dane B, Yayla M, Dane C, Cetin A. Prenatal diagnosis of Bartter syndrome with biochemical examination of amniotic fluid: case report. Fetal Diagn Ther. 2007;22(3):206-8.
Antenatal Bartter syndrome typically presents with marked fetal polyuria that leads to polyhydramnios and premature delivery. In our case, polyhydramnios was detected at 26 weeks of gestation and amniotic fluid chloride level was high. Serial amnion-drains were performed. During indomethacine treatment, fetal bradycardia developed. The mother was given daily oral potassium to maintain normal serum level and prevent fetal arrhythmias. After birth, hypokalaemic alkalosis, low chloride, hyper-reninemia and hyperaldosteronemia were detected.
