Distal limb deficiency following chorionic villus sampling?



We have reviewed the follow-up of almost 3000 completed preganancies in the Münster CVS Program and identified 4 children with distal limb deficiencies. Two cases involved only minor anomalies of distal digital phalanges. One child had a Hanhart anomaly (hypoglossia hypodactylia).

We also reviewed 24 cases of limb defects following CVS reported previously. With the exception of a single series, neither the overall incidence of affected children nor cases reported from larger series provide unambiguous evidence of an increased risk of distal limb deficiency caused by CVS.
