F. Raga et al., SUBCHORIONIC PLACENTAL CYST - A CAUSE OF FETAL GROWTH-RETARDATION - ULTRASOUND AND COLOR-FLOW DOPPLER DIAGNOSIS AND FOLLOW-UP, Journal of the National Medical Association, 88(5), 1996, pp. 285-288
Subchorionic placental cysts are ominous findings. When attached near
the umbilical cord insertion, the risk of umbilical cord constriction
is increased. This may cause fetal growth retardation and intrauterine
asphyxia. This article reports a case of subchorionic placental cyst
diagnosed in the first trimester by transvaginal ultrasound. Color Dop
pler ultrasound demonstrated a reduction of the umbilical cord bloodst
ream as the cyst increased in size. Fetal growth retardation was evide
nt in the third trimester.
