Needle puncture of fetus: a complication of second-trimester amniocentesis.

Needle puncture of the fetus has rarely been reported with midtrimester amniocentesis. This paper contains the report of five cases of needle scars in infants born after second-trimester amniocentesis for prenatal diagnosis of fetal genetic disorders. Since this complication may be more frequent than has been previously believed, there is the possibility that damage to the fetus may occur. It is suggested that the products of all abortions and all live-born and stillborn infants delivered following amniocentesis should be examined for evidence of injury.
