“…Alouini et al 2 found that complete placenta previa and most placentas less than 1 cm from the internal cervical os did not migrate. Most cases with placentas located more than 1 cm away, migrated three to four weeks later.…”

“…However, these complications are also based on extrapolation from studies that investigated placenta previa and LLP as a single group. [1][2][3][4][5] Moreover, data regarding differences between LLP that resolved early versus those that resolved later or persisted until delivery are lacking. In this study, we aimed to create a clinical model that would predict persistent LLP, based on clinical and laboratory parameters among pregnant women with LLP diagnosed at 13-16 weeks of gestation.…”

“…Low-lying placenta (LLP) is diagnosed when the inferior placental edge is within 2 cm of the internal cervical os but does not overlie it. [1][2][3] The management of pregnancies with LLP is based on data published regarding placenta previa. Information regarding the natural course, clinical and laboratory parameters and outcomes of isolated, LLP has not been published.…”

Objective Finding a predictive model for persistent low lying placenta (LLP) based on early clinical and laboratory parameters. Methods This retrospective cohort study included patients with LLP detected during early anatomy scan. Additional transvaginal ultrasound exams assessed for resolution at 22–24 weeks and 36–39 weeks. Patients were categorized as: Group 1–LLP resolved by the second trimester scan, Group 2- LLP resolved by the third, and Group 3–LLP persisted to delivery. Clinical and laboratory parameters were compared between groups. A linear support vector machine classification was used to define a prediction model for persistence. Results Among 236 pregnancies with LLP, 80% resolved by 22–24 weeks, 10.5% resolved by 36–39 weeks and 9.5% persisted until delivery. Second trimester hCG levels were higher the longer the LLP persisted (0.8MoM + 0.7 vs. 1.13MoM + 0.4 vs. 1.7MoM + 1.5, P = 0.03, respectively) and Cervical length was shorter (P = 0.008, P = 0.02, respectively). A linear SVM classification model was calculated based on these parameters. The predictive accuracy of this model was 90.3%. Conclusion LLP persistence can be predicted with an accuracy of 90.3%, as early as the beginning of the second trimester. Persistence vs. resolution of LLP may represent different entities and not a spectrum of the same condition over time.

“…Vaginal bleeding and uterine contractions in the second trimester may be due to various conditions, including placental previa, placental abruption, chronic abruption‐oligohydramnios sequences, and subchorionic hematoma 7‐10 . Among these conditions, placental abruption has a high mortality rate 11 and should be excluded.…”

“…se catalogaría como placenta previa y la evaluación ecográfica y manejo clínico deben ser más estrictos. Esto concuerda con el estudio de Alouini et al donde se evidenció que la mayoría de placentas que se encontraban a menos de 1 cm del orificio cervical interno no presentaron migración, mientras que las que se encontraban por encima de 1 cm migraron de tres a cuatro semanas más tarde en su mayoría (42).…”

Placenta previa: factores de riesgo e impacto en la morbimortalidad materno-perinatal en Bogotá, Colombia

Introducción. La placenta previa puede causar hemorragias en la segunda mitad del embarazo que pueden llegar a comprometer la salud materno-perinatal. Conocer los factores de riesgo asociados permite identificar tempranamente gestantes con alto riesgo de placenta previa. Objetivo. Describir los factores de riesgo de placenta previa en una muestra de gestantes atendidas en Bogotá D.C., Colombia, así como su morbimortalidad materno-perinatal. Materiales y métodos. Estudio descriptivo retrospectivo. Se incluyeron 17 gestantes diagnosticadas con placenta previa que ingresaron entre 2013 y 2017 a la Unidad de Alto Riesgo Obstétrico de un hospital de tercer nivel. Se revisaron las historias clínicas para recolectar datos sobre los factores de riesgo y sobre características clínicas y sociodemográficas. En el análisis descriptivo, para las variables cuantitativas se calcularon medias y desviaciones estándar y para las cualitativas, frecuencias absolutas y relativas. Resultados. Los factores de riesgo más frecuentes fueron número de embarazos ≥4 (64.70%), edad materna >35 años (29.41%) y aborto previo (29.41%). La morbilidad materna fue mayor que la fetal: tres pacientes requirieron transfusión de hemoderivados y en otra fue necesario realizar histerectomía subtotal, mientras que no se reportaron complicaciones perinatales, a excepción de un mortinato. Conclusiones. Haber tenido ≥4 embarazos, tener una edad materna >35 años y el antecedente de aborto fueron los factores de riesgo más frecuentes; además, el grado de las complicaciones materno-perinatales fue independiente del tipo de placenta previa. Saber cuáles son las gestantes con mayor riesgo de presentar esta condición mediante la identificación temprana de estos factores permite brindarles un mejor abordaje clínico, lo que permitirá disminuir la morbimortalidad del binomio madre-hijo.
