Coelocentesis was performed in 20 singleton pregnancies at 6-10 weeks
of gestation and 2-13 days before planned termination. The control gro
up consisted of 100 women who were also undergoing planned termination
and were matched with the study group for maternal age and gestation.
During the follow-up period, there were five miscarriages (25 per cen
t) after coelocentesis and five in the control group (5 per cent) (chi
(2) = 6.68; P < 0.01). The high risk of miscarriage following coelocen
tesis makes the technique unsuitable for early prenatal diagnosis. (C)
