We evaluated the risk factors for massive bleeding based on angiographic findings in patients with placenta previa and accreta who underwent balloon occlusion of the internal iliac artery (BOIA) during cesarean section. ⋯ Angiographic visualization of collateral circulation from the round ligament artery to the uterus may be a risk factor for massive bleeding in patients with placenta previa and accreta who have undergone BOIA during cesarean section.

Random placenta margin incision for control hemorrhage during cesarean delivery complicated by complete placenta previa: a prospective cohort study.
Introduction: Complete placenta previa (CPP) is one of the most problematic types of abnormal placenta, which is further complicated by placenta accreta or percreta that can unexpectedly lead to catastrophic blood loss, infection, multiple complications, emergency hysterectomy, and even death. The present study aimed to assess the efficacy of random placenta margin incision in controlling intraoperative and total blood loss during cesarean section for CPP women. Methods: A prospective cohort study, including a total of 100 consecutive pregnant women with CPP, was performed at a tertiary university-affiliated medical center between March 2016 and July 2017. ⋯ No women had an intraoperative urinary bladder injury, postoperative wound infection, and required relaparotomy, owing to intra-abdominal bleeding. The median hospitalization time was 5.41 (4.18-7.58) d. Conclusion: The random placenta margin incision may be a potentially valuable surgical procedure to control the volumes of intraoperative and postoperative blood loss and reduce the incidence of postpartum hemorrhage among women with complete placenta previa.

Observational Study
Uterine artery ligation before placental delivery during caesarean in patients with placenta previa accreta.
To investigate the influence of uterine artery ligation before placental delivery during cesarean section on postpartum hemorrhage (PPH) and related complications in patients with placenta previa accreta. A retrospective study was conducted of data from 78 patients with pernicious placenta previa, treated at Fujian Provincial Maternal and Child Health Hospital (Fuzhou, China) between January 2014 and June 2018. Twenty-nine patients underwent uterine arterial ligation before placental delivery (UALBPD), and the other 49 patients in the control group did not undergo peri-paracentesis before the delivery of the placenta. ⋯ The reduction in hemoglobin was 2.63 ± 1.85 g/L in the UALBPD group and 5.41 ± 2.38 g/L in the control group (P < .0001). The reduction in hematocrit was 2.96 ± 4.07 in the UALBPD group and 6.77 ± 8.74 (%) in the control group (P = .009). Bilateral uterine artery ligation before the delivery of the placenta in women with placenta accreta can effectively reduce the amount of intraoperative blood loss, the incidence of PPH, and the risk of complications, such as hysterectomy.

Associated factors of blood transfusion for Caesarean sections in pure placenta praevia pregnancies.
This study aimed to evaluate associated factors of blood transfusion for Caesarean sections in pure placenta praevia pregnancies. ⋯ Previous Caesarean section, anterior placentation, major placenta praevia, preoperative bleeding of more than 250 mL, preoperative anaemia and emergency Caesarean section were independent factors that increased the risk of blood transfusion for Caesarean section in pure placenta praevia pregnancies.

The incidence of pernicious placenta previa (PPP) and placenta accreta (PA) is increasing in China. Excessive blood loss in these women is an important cause of maternal death and emergency hysterectomy. Performing a traditional cesarean section (CS) in women with PPP is stressful for obstetricians because avoiding cutting the placenta is difficult. As a result, sudden life-threatening bleeding may be encountered. Therefore, there is an urgent need to establish a novel operative method for PPP and PA that is safe for both the mother and neonate, and less stressful for the surgeon. ⋯ If PPP and PA are suspected, placental magnetic resonance imaging is recommended for definitively determining whether a transverse fundal incision can be made. If feasible, we strongly recommend that PTUI CS combined with cell salvage are used to minimize bleeding for high-risk patients with PPP and PA complicated with anemia and an unexplained decrease in Hb levels after transfusion of 3 units of allogeneic red blood cells. Anesthesiologists should be vigilant to maintain uterine relaxation from the time of delivery of the neonate to a second transverse incision in the lower segment of the uterus. This is a key element of successful PTUI CS. Additionally, the use of intraoperative cell salvage is recommended when it can be expected to reduce the likelihood of donor red cell transfusion.
