Abstract

OBJECTIVE
To quantify the improvement in ultrasonographic fetal imaging following diagnostic amnioinfusion for the indication of unexplained midtrimester oligohydramnios. METHODS: Eight patients were referred for unexplained midtrimester oligohydramnios were retrospectively reviewed. Videotapes of those undergoing diagnostic antenatal amnioinfusion were analyzed for quality of visualiztion of routinely imaged structures before and after the infusion procedure. And genetic amniocentesis was performed in all patients. RESULTS: The overall rate of adequate visualization of fetal structures improved from 64.1% to 95.2% (P=0.008). In most cases we were able to achieve a definitive diagnosis. CONCLUSION: Diagnostic amnioinfusion can facilitate fetal imaging and increase diagnostic precision in the setting of unexplained severe oligohydramnios.
