Resumen: Determinar si la placenta previa y número de cesáreas son factores de
riesgo para placenta ácreta.
Material y métodos: Se realizó un estudio retrospectivo analítico observacional
casos y controles mediante la selección y revisión de 142 historias clínicas,
asignando 71 casos y 71 controles de las gestantes atendidas en el Hospital
Regional Docente de Trujillo. Los datos obtenidos se construyeron tablas cruzadas
para el análisis bivariado y medida de riesgo Odds ratio con IC 95% y el estudio de
la influencia de las variables independientes y su asociación mediante análisis
multivariado de regresión logística.
Resultados: Los datos obtenidos fueron evaluados en este estudio. La edad
materna avanzada con una frecuencia de 58%, la gravidez con dos gestas 20%,
más de tres gestas 77% (p<0,001) fueron variables intervinientes asociadas a
placenta ácreta evaluadas en este estudio que predominaron en el grupo de casos
al igual que la presencia de al menos un aborto con 37%, dos abortos 13% (p=0,049)
y legrados uterinos con 24% en el grupo de casos versus 11% en el grupo de control
(p=0,047). La placenta previa con 78% en el grupo de casos (p = 0,001 OR IC
95%=3,43) y el número de cesáreas, para 2 cesáreas (p=0.001 OR 12.128 IC
95%=4.178-35.205) y 3 cesáreas (p=0.001 OR 14.035 IC 95%=3.424-57.534)
fueron los factores de riesgo independientes para acretismo placentario evaluados
en el presente estudio. También se estudió a las cesáreas más placenta previa y su
asociación con el incremento de riesgo de placenta ácreta, con un 73% en el grupo
con acretismo placentario versus 10% en el grupo de control.
Conclusión: La placenta previa y tener al menos 2 cesáreas son factores de riesgo
independientes para presentar acretismo placentario. La asociación de ambas
variables incrementa el riesgo de presentar acretismo placentario respecto a
quienes sólo tengan el antecedente de placenta previa o sólo una cesárea. En este
estudio no se logró determinar cuál es el tipo de acretismo placentario más
frecuente.
To determine if the placenta previa and the number of cesarean sections are risk factors for placenta accreta. Material and methods: A retrospective, analytical, observational case-control study was carried out by selecting and reviewing 142 medical records, assigning 71 cases and 71 controls to pregnant women treated at the Trujillo Regional Teaching Hospital. The data obtained were cross-tabulated for the bivariate analysis and risk measurement Odds ratio with 95% CI and the study of the influence of the independent variables and their association through multivariate logistic regression analysis. Results: Advanced maternal age with a frequency of 58%, pregnancy with two pregnancies 20%, more than three pregnancies 77% (p <0.001) were intervening variables associated with placenta accreta evaluated in this study that predominated in the group of cases as well than the presence of at least one abortion with 37%, two abortions 13% (p = 0.049) and uterine curettage with 24% in the case group versus 11% in the control group (p = 0.047). The placenta previa with 78% in the case group (p = 0.001 OR 95% CI = 3.43) and the number of caesarean sections, for 2 caesarean sections (p = 0.001 OR 12.128 95% CI = 4.178-35.205) and 3 caesarean sections (p = 0.001 OR 14.035 95% CI = 3.424- 57.534) were the independent risk factors for placental accreta evaluated in the present study. Cesarean sections plus placenta previa and their association with the increased risk of placenta accreta were also studied, with 73% in the group with placental accreta versus 10% in the control group. Conclusion: Placenta previa and having at least 2 cesarean sections are independent risk factors for presenting placental accreta. The association of both variables increases the risk of presenting placental accreta compared to those who only have a history of placenta previa or only a cesarean section. In this study, it was not possible to determine which is the most common type of placental accreta.
