CONFINED PLACENTAL MOSAICISM IN CVS AND PREGNANCY OUTCOME

The perinatal outcome of 26 patients with confined placental mosaicism (CPM) detected in chorionic villus sampling (CVS) who wished to conti nue their pregnancies was compared with that of two controls per patie nt matched for age and parity (n = 52). There were no significant diff erences in birth weight or gestational age at delivery between patient s with CPM and controls. There were no cases of intrauterine growth re tardation (IUGR) in the CPM patients as compared with two (2/52, 3.8 p er cent) in the control group (P>0.05). There was no significant incre ase in fetal loss between the study group (1/26, 3.6 per cent) and the controls (1/52, 1.9 per cent) (P>0.05).
