Introduction: Chromosomal abnormalities are changes that affect the number and structure of chromosomes. The risk of a chromosomal genetic disease increases with increasing maternal age. Amniocentesis is an important means of cytogenetic prenatal diagnosis for early detection of the same. Objective: to analyze the behavior of the program of prenatal cytogenetic diagnosis in the province of Pinar del Rio in 2013. Material and methods: a descriptive, retrospective study slitting the total of pregnant women was performed with amniocentesis indication in 2013 in the province of Pinar del Rio, analyzing the main parameters related to the cytogenetic prenatal diagnosis. Results: in the analyzed period a total of 481 prenatal studies were conducted, with the city of Pinar del Río the highest number of cases. Advanced maternal age is the main display and a total of 10 positive cases were diagnosed to 2.3%. Conclusions: prenatal cytogenetic diagnosis was achieved clarify the fetal karyotype in pregnant women at risk, so the DPC remains an important program in the early detection of chromosomal abnormalities, providing a starting point for proper genetic counseling to the family.
