OBJECTIVE: Analysis of prenatal and postnatal incidence of selected types of birth defects in the Czech Republic in the period of 1994-2001. In the postnatally diagnosed cases the survival in the course of the first year of life was analyzed. Selected birth defects--omphalocele, gastroschisis, abdominal wall defects, renal agenesis and hypoplasie, cystic kidney disease, diaphragm hernia.
TYPE OF STUDY: Retrospective analysis from registry of birth defects in the Institute of Health Information and Statistie of the Czech Republic in the period of 1994-2001.
METHOD: The authors analyzed frequency of prenatally and postnatally diagnosed cases of 6 selected types of birth defects in the period of 1994-2001 in the Czech Republic. In cases where the diagnosis was established after birth, analysis of survival and death rate during the first year of life was performed for selected birth defects.
RESULTS: In the period of 1994-2001, 745,410 children were born in the Czech Republic. There were 22,711 children with one or more birth defects diagnosed in this cohort during the first year of life. The mean incidence of all cases in this period of observation was 304.52 per 10,000 live born children. The percentage of prenatally diagnosed cases, ended for this diagnosis in the above mentioned period of observation, was 66% in abdominal wall defects, 55% in omphalocele and 77% in gastroschisis. In cases where the diagnosis was established after birth, 93.55% of children survived the first year of life. In cases of birth cystic kidney 25% were diagnosed prenatally and ended for renal agenesis and hypoplasie of the kidneys and 27% due to cystic kidney. In cases of diaphragmatic hernia, 31% of cases were diagnosed an ended prematurely after positive prenatal diagnosis, and about one third of affected children died during the first year of life.
CONCLUSION: Incidence of these types of birth defects in newborns in the Czech Republic is presently lower than in previous years particularly due to successful prenatal diagnostics. Cases where the diagnosis is established after delivery represent an important part of perinatal, neonatal and post-neonatal mortality and morbility.
