Varieties of foetal congenital abnormality

The purpose of the study is to determine the type of fetal congenital abnormalities found among high risk pregnancies admitted in Fetomaternal Unit of Obs & Gynae Department in BSMMU. This is a cross sectional study done during the period July 2007 to June 2010. All the patients admitted with congenital abnormality in fetomaternal unit during this study period were included in this study. One hundred five cases had congenital abnormality of fetus among 1134 deliveries. Out of which 46.66% had CNS abnormalities and 19.04% had renal abnormalities. Out of CNS abnormalities Hydrocephalous (40.81%) was the most common, 31.42% patients were of age between 20-24 years, 69.52% patients had parity between 1-3, 35.37% had deliveries ≥ 37 weeks, 69.52% patients had vaginal deliveries, 82.89% patients were terminated by prostaglandins, 96.19% patients had no drug history other than intake of iron and calcium, 26.67% babies had birth weight between 1.1-1.5 kg and 70.4% were of male babies. Advances in ultrasound technology have made possible the prenatal identification of an increasingly large number of fetal congenital malformations. Now fetal anatomical survey is performed routinely between 18 to 22 weeks.
