The use of saline solution as a contrast medium in suspected diaphragmatic hernia and renal agenesis
Article Abstract:
Infusing a saline solution into the amniotic cavity may improve the prenatal diagnosis of a fetal diaphragmatic hernia or renal agenesis using an ultrasound scan. A diaphragmatic hernia is the protrusion of abdominal or retroperitoneal structures into the thorax through the esophageal opening in the diaphragm. Renal agenesis is the absence of kidneys. Among 10 fetuses between 16 and 27 weeks old that had ultrasonography in conjunction with a saline solution infusion, five had a suspected diaphragmatic hernia and five had suspected renal agenesis. A diaphragmatic hernia was demonstrated in four fetuses and kidney agenesis in four fetuses.
