oligohydramnios sequence


oligohydramnios sequence

a pattern of anomalies, usually causing death shortly after birth, resulting from compression of the fetus secondary to oligohydramnios; the anomalies may result from renal agenesis or other urinary defects or leakage of amniotic fluid. Infants have a characteristic flattened facies (Potter facies) and skeletal anomalies such as clubbed feet and hypoplasia of the lungs.
