“…Without existing evidence to guide practice, clinicians should individualize the decision to modify activity or recommend pelvic rest for women with placenta accreta spectrum. Antenatal bleeding, preterm labor, and preterm prelabor rupture of membranes (also referred to as premature rupture of membranes) are associated with unscheduled delivery as well as maternal and neonatal morbidity (9,26,57). Women with these complications are most likely to benefit from hospitalization.…”

“…Multiple morbidities are associated with placenta accreta spectrum (PAS), including but not limited to, hemorrhage, the need for massive crystalloid and blood transfusion, acute kidney injury, and iatrogenic surgical injury to ureter, bowel, bladder and major pelvic vessels . Acute severe hypocalcemia is a life‐threatening complication of massive blood transfusion that requires prompt treatment to avoid catastrophic cardiac consequences.…”

Introduction We aimed to determine predictive factors for severe hypocalcemia in women with placenta accreta spectrum. Material and methods Study of 123 women with histology‐proven placenta accreta spectrum with cesarean hysterectomy between 2011 and 2017. Two groups were selected: Cases: critically low (“panic value”) serum total calcium (≤7 mg/dL) and Controls: normal serum total calcium (≥8.5 mg/dL). Regression and receiver operating characteristic (ROC) analyses were performed to evaluate the potential associations. Results There were 13 women with critically low (cases) and 18 with normal calcium (controls). Baseline characteristics were not statistically different. The median estimated blood loss, units of red blood cells (RBCs) transfused and volume of crystalloid transfused, were higher in the low calcium group. Six out of 13 (46.2%) cases had received ≥4 units of RBCs during surgery vs 2 of 18 (11.1%) controls (P = 0.04). ROC analysis showed that estimated blood loss, units of RBCs transfused, and crystalloid transfused were associated with severe hypocalcemia and univariate regression analysis confirmed that estimated blood loss ≥1500 mL, RBC transfusion ≥4 units, and crystalloid transfused ≥4L were associated with severe hypocalcemia. Conclusions Intraoperative transfusion of ≥4 units RBCs is predictive of the development of severe hypocalcemia in placenta accreta spectrum patients experiencing active bleeding. Empiric replacement of 1 g CaCL2 is recommended for every 4 U RBC transfused.

Background The present study aims to determine the predictive value of vascular endothelial growth factor (VEGF) and placenta growth factor (PLGF) for placenta accreta and for the comparison of the serum level of VEGF and PLGF in normal pregnant women and women with placenta accreta spectrum (PAS).Methods This prospective case-control study was conducted during the 2 years in two hospital in Shiraz, Iran from 2017 to 2019. The inclusion of the study was 90 singleton pregnant women: 45 of them in gestational ages of 28-34 weeks with pathological confirmation of placenta accreta spectrum and 45 healthy pregnant women. In the PAS group, according to pathology reports on the placenta, we divided all cases to placenta accreta, percreta, and increta. Maternal serum level of VEGF and PLGF were measured before the termination of pregnancy and diagnostic accuracy of each factor was evaluated.Results In PAS group, 75 percent of patients had placenta previa and unlike the control group, there was a significant difference in the gravidity, number of cesarean section, maternal age, and serum level of PLGF (p< /001); while in VEGF, the difference was not statistically significant. ConclusionsThe results of the present study revealed that the maternal serum level of PLGF could be considered as an accurate predictive test in patients with PAS. BackgroundWith the rising rate of cesarean section (C/S) worldwide, placenta accreta is considered as a new pathological matter [1]. According to the depth of invasion of placenta to myometrium, the placenta accreta spectrum (PAS), formerly known as morbidly adherent placenta, is divided into three groups: placenta accreta with superficial myometrial invasion, placenta increta with deep myometrial invasion, and placenta percreta with deep invasion of placenta to serosa of uterus and sometime to adjacent organs [1,2].In normal placentation, extravillous trophoblasts containing interstitial and endovascular cells invade decidua and superficial myometrium and cause remodeling of the basilar and spiral artery [3, 4].Thus, excessive trophoblastic invasion, abnormal decidualization, abnormal angiogenesis, and 4 decrease of apoptosis of trophoblasts can result in abnormal adherence of placenta [5, 6].In uterine scars such as site of C/S, total or partial absence of decidua, thinning, irregularity or absence of Nitabuch's layer, and subsequently, placenta accreta can happen [4,[7][8][9].Also, deficient trophoblastic invasion can be harmful and is related to abortion, preeclampsia, intrauterine growth restriction (IUGR), and preterm delivery [3].The most important risk factors of PAS are previous C/S and intrauterine operation [10][11][12]. Other risk factors included placenta previa, multiparity, maternal age, any previous uterine surgery, surgical abortion, radiation, endometrial ablation, in vitro fertilization (IVF), chemotherapy, and adenomyosis [7,[10][11][12].The rate of C/S in the United States is 32-33% and placentas accreta is equal to 1/540-1/2500 of total deliveries[1]. It has increased...
