Abstract

We compared the rate and types of fetal malformations detected by targeted ultrasound during 1991-1994 and 19811984, when the use of ultrasound was limited and diagnostic techniques were scarce. Data were collected from the Ultrasound Unit of Rabin Medical Center, Petah Tikva, Israel. Results indicated a significant increase in detection rate from 17% to 22%. There was a significant increase in the frequency of renal (38% vs. 19.5%) and cardiovascular defects (7.5% vs. 4%), and a significant (threefold) decrease in central nervous system defects. When the 1991-1994 findings were further compared with those of routine screening performed for 988 consecutive low risk pregnancies in 1994, a significantly higher detection rate of prenatal malformations was found for targeted ultrasound (22% vs. 1.2%). These findings have important implications for future health planning.
