[The nosological structure of congenital fetal malformations in Novosibirsk].

The authors comparatively studied the nosological structure of congenital malformations (CM) in 395 fetuses at 22-27 weeks post-conception age and the efficiency of prenatal diagnosis in Novosibirsk. They analyzed 227 and 168 autopsy protocols of fetuses with CM over the periods from 2000 to 2002 and from 2006 to 2008, respectively. In the nosological structure of mortality among low-weight fetuses, CM ranked third in 2000-2002 and second in 2006-2008. During all the observation periods, the structure of CM showed 4 major systemic CMs: multiple anomalies of development, the central nervous and urogenital systems, heart, and vessels; multiple CMs occupying a prominent place. There was a preponderance of hydrocephalus and spinal hernias among central nervous system CMs, that of hydronephrosis with megaureter among urogenital CMs, and that of ventricular septal defect among CMs of the heart and vessels. The efficiency of prenatal diagnosis in the above observation periods was 46-75%.
