OBJECTIVE: The objective of the study was to compare outcomes of women with placenta accreta spectrum(PAS) who underwent emergency cesarean hysterectomy with and without prophylactic intravascular balloon catheters. Methods Sixty-three cases who had emergency hysterectomy related to PAS disorders were retrospectively analyzed. Subjects with prophylactic intravascular balloon catheter placement plus hysterectomy were compared with those who had hysterectomy alone. The cases were divided into three groups: infrarenal aortic artery balloon occlusion (IAABC) group (who had IAABC plus hysterectomy, n  = 31), internal iliac artery balloon occlusion (IIABOC) group (who had IIABOC plus hysterectomy, n  = 17), and hysterectomy alone group (control group n  = 15)...

Background: Placenta accreta spectrum (PAS) is a major cause of maternal morbidity and mortality in modern obstetrics, however, few studies have explored the underlying molecular mechanisms and biomarkers. In this study, we aimed to elucidate the regulatory RNA network contributing to PAS, comprising long non-coding (lnc), micro (mi), and messenger (m) RNAs, and identify biomarkers for the prediction of intraoperative blood volume loss. Methods: Using RNA sequencing, we compared mRNA, lncRNA, and miRNA expression profiles between five PAS and five normal placental tissues...

Intentional retention of the placenta (IRP), or 'conservative' treatment or management, entails opening the uterus, delivering the baby, tying and cutting the umbilical cord at its placental insertion site, leaving the placenta in the uterus and waiting for its complete spontaneous resorption in women with placenta accreta spectrum (PAS). The uterine preservation rate with this approach is about 78%, and severe maternal morbidity about 6%; these rates are respectively lower and higher in subgroups of women with placenta percreta...

The incidence of placenta accreta spectrum (PAS) is increasing and will become more commonly encountered by obstetric anaesthetists in the elective and emergency settings. Significant maternal and neonatal morbidity is associated with these disorders, and hence it is important for anaesthetists to have early involvement in perioperative planning. Major haemorrhage should be anticipated and requires robust perioperative preparation including Patient Blood Management (PBM) and use of intraoperative strategies for haemorrhage management wherever possible...
