[Clinical pathologic analysis of congenital malformations in 411 perinates: with 80 autopsy materials].

411 cases of malformed babies in 1960-1985 were analyzed, giving an incidence of 6.8%. The clinical data and autopsy materials showed that the order of occurrence of malformation in various systems was: nervous system, face and neck, muscle, bone and digestive system. Autopsy rate was 37.4% in this series. The ratio of malformed male babies to female was 1.3 to 1. 46.5% of the mothers with malformed baby were at age of 25-29 years and 66.2% delivered at 37 to 41 weeks of gestation. 69.3% of mothers with malformed baby had gestational complications 11 times as high as those delivering normal neonate in the same period (P less than 0.01). Of them hydramnion, premature rupture of membranes, oligoamnios, neonatal asphyxia were obviously higher than those pregnancies with normal baby (P less than 0.01). There is mainly discussed the clinical value of autopsy and the preventive measures in decreasing birth of malformed babies.
