Active clinical trials for "Placenta Accreta"

The placenta accreta spectrum (PAS) which includes accreta, increta, and percreta represents a significant obstetric challenge. PAS complicates as many as 1 per 500 pregnancies and this risk is increased with prior cesarean deliveries. Antenatal diagnosis of PAS allows for multidisciplinary planning and delivery before the onset of labor and/or vaginal bleeding. This approach has reduced maternal morbidity rates, including less blood loss, fewer transfusion requirements and, intraoperative urologic injuries as well as improve fetal outcome. Ultrasound evaluation, with grayscale and color Doppler imaging, is the recommended first-line modality for diagnosing PAS. Grayscale ultrasound features suggestive of placenta accreta include an inability to visualize the normal retroplacental clear zone, irregularity and attenuation of the uterine-bladder interface, retroplacental myometrial thickness, presence of intraplacental lacunar spaces, and bridging vessels between the placenta and bladder wall when using color Doppler. Magnetic resonance imaging (MRI) has been used to predict the depth of placental invasion, but it is expensive and often not immediately available. Recently, a new imaging technique utilizing three-dimensional (3D)/four-dimensional (4D) volume rendering ultrasound (VRU) was proposed as a promising tool for the preoperative diagnosis of placenta previa accerta spectrum. By using "crystal vue" and "realistic vue" volume rendering mode, it could detect 11 out of 12 cases (91.6%) of PAS which was subsequently confirmed during surgery. Accordingly, The aim of this study is to examine the diagnostic performance of 3D/four-dimensional (4D) volume rendering ultrasound (VRU) for placenta previa accerta spectrum in correlation with the clinical (operative) and pathological findings.

Cell free fetal DNA might predict abnormal placental invasion

The accuracy of sonographic prenatal detection of invasive placentation is unclear. The objective of this prospective, multicenter, observational study is to assess the performance of ultrasound for prenatal identification of invasive placentation in women with placenta previa. This study involves more than 25 hospitals in Italy.

comparative study between the incidence of urological injury in case of placenta accreta in cases where urological surgical staff are participating in the operation from the start and in cases where the operation is carried by the gynecological staff only

Placenta accreta spectrum (PAS) is a set of placentation disorders that are associated with trophoblastic invasion through the physiologic decidual-myometrial junction zone. PAS may be associated with massive obstetric hemorrhage, surgical injuries, maternal intensive care unit (ICU) admission, reoperation, and prolonged hospitalization. This study aims at estimating the validity of "MOGGE placenta accreta risk-antepartum score" or "MOGGE PAR-A score" in predicting potential outcomes once PAS is diagnosed antenatally. In addition, it evaluates the validity of "MOGGE placenta accreta risk-peripartum score" or "MOGGE PAR-P score" in calculating the probability of the same outcomes using baseline features in conjugation with both disease-and surgery-related peripartum variables,thereby,assist designation of the most suitable management. Finally , MOGGE CON-PAS score was created for the subgroup of women who were subject to conservative management to predict probability of uterine preservation success.

Cases of previous cesarean with placenta previa anterior underwent cesarean section. Placenta accreta is diagnosed during cesarean section &confirmed by pathology. All complications are monitored in cases with placenta accreta and without.
