LLANUSA RUIZ, Celia et al. Value of first trimester epidemiologic and sonographic markers as chromosome-diseases risk indicators. Rev Cubana Obstet Ginecol [online]. 2009, vol.35, n.4, pp. 75-84. ISSN 1561-3062.
Prenatal screening of chromosomal anomalies using epidemiological and sonographic markers during the first trimester, allow identifying pregnant with high risk of chromosome disease; we offer the cytogenetics prenatal diagnosis as option. OBJECTIVES: to made a preliminary assessment on usefulness of echographic marker during the first trimester like predictors of chromosomal anomalies in pregnant with a cytogenetics prenatal diagnosis. METHODS: a descriptive, retrospective and cross-sectional study was conducted for a preliminary assessment on usefulness of ultrasonograpic markers like predictors of chromosomal anomalies during the first trimester. In research a sample including 2 507 pregnants with cytogenetics study prescribed in cytogenetics consultation of Genetics Provincial department of Havana City from the “Ramón González Cor” Gynecology-Obstetrics Hospital during January, 2006 and December, 2007. RESULTS: the high transillumination nuchal increased in a significant way the risk of chromosomal anomalies. Nasal bone has not association with other positive karyotypes. Given the no systemic performing of ductus venous, it was impossible to establish a statistical association. CONCLUSIONS: the increase nuchal transillumination increases significantly the risk of chromosomal defects; however, its sensitivity was below the previously described in other researches.
