RESUMO

Resumen En el Instituto de Medicina Fetal y Genética Humana de São Paulo se ofrecen, a las gestantes que tienen un riesgo aumentado para anomalías cromosómicas, diferentes técnicas, entre ellas, la Biopsia de Vellosidad Corial Transabdominal (BVCTA) y la Amniocentesis Precoz (AP). El objetivo del presente estudio es realizar una comparación de la frecuencia de pérdidas fetales y anomalías congénitas presentadas en cada uno de los procedimientos, ambos realizados por los mismos operadores, en la misma edad gestacional (12-14 6/7 semanas) y bajo un abordaje transabdominal. Fueron analizadas retrospectivamente 432 AP y 418 BVCTA. Todos los procedimientos de colecta fueron monitorizados por ultrasonografía. La frecuencia de pérdidas fetales espontáneas fue del 4,9 % en AP y de 5,3 % en BVCTA, una diferencia no significativa. No se encontraron diferencias significativas entre los dos procedimientos al comparar las frecuencias de pérdidas en cada semana de gestación. Sangrado y pérdida de líquido amniótico fueron más frecuentes en AP que en la BVCTA. Esa diferencia fue significativa en el caso de la pérdida de líquido amniótico. En algunos casos este hallazgo se relacionó con pérdida fetal. La incidencia de prematuridad y bajo peso al nacimiento no difirió significativamente entre los dos procedimientos. La mayor frecuencia de problemas respiratorios registrada en AP no fue significativa en comparación con BVCTA. No se observó diferencia significativa en la incidencia de anomalías músculo-esqueléticas. La amniocentesis después de catorce semanas presenta un bajo riesgo de pérdida fetal o anomalías congénitas. La BVCTA, debe ser realizada alrededor de la semana doce de gestación.


Abstract In the Institute of Fetal Medicine and Human Genetics of São Paulo are offered, pregnant women have an increased risk for chromosomal abnormalities, different techniques, among them, Transabdominal Corial Vellosity Biopsy (BVCTA) and Precocious Amniocentesis (AP). The objective of this study is to compare the frequency of Hepatitis and congenital anomalies presented in all procedures, both performed by operators, in the same gestational age (12-14 6/7 weeks) and under a transabdominal approach. 432 AP and 418 BVCTA were analyzed retrospectively. All collection procedures were monitored by ultrasonography. The spontaneous fetal frequency was 4.9% in AP and 5.3% in BVCTA, a non-significant difference. There is no difference in results compared to gestation times. Bleeding and loss of amniotic fluid were more frequent in AP than in BVCTA. That difference was significant in the case of the loss of amniotic fluid. In some cases, this finding was related to fetal loss. The incidence of prematurity and birth weight without difference between the two procedures. The highest frequency of respiratory problems recorded in AP was not significant compared to BVCTA. There is no significant difference in the incidence of musculoskeletal abnormalities. Amniocentesis after 14 weeks presents a low risk of fetal loss or congenital anomalies. The BVCTA should be close to the twelfth week of gestation.

RESUMO

We sought to determine whether early amniocentesis is a safe and acceptable method of genetic evaluation in early pregnancy. During the 20-month period from February 1994 to September 1995, 80 consecutive early amniocentesis were performed transabdominally at 12(+3)-14(+6) weeks of gestation and 305 consecutive mid-second-trimester transabdominal amniocenteses were performed at 16(+0)-18(+0) weeks of gestation. All amniotic fluid samples were cultured using flask method. There were no significant differences between the early and mid-second-trimester amniocenteses in failed sampling, ambiguous results, pregnancy loss within 4 weeks after the procedure, pregnancy loss from 4 weeks after procedure to 28 weeks of gestation, preterm birth, and perinatal death. We may conclude that early amniocentesis is a safe and acceptable method for prenatal diagnosis.
