When cesarean hysterectomy is scheduled in cases of placenta previa accreta/increta/percreta, it is necessary that the departments of obstetrics, anesthesiology, blood transfusion, urology, and radiology hold a preoperative conference to assure full preparation for the surgery. A ureteral stent inserted just before cesarean section serves as a marker. A uterine incision should be made at a site free of placental contact.

Cesarean section for placenta previa accreta spectrum carries a significant risk of massive hemorrhage. Hence, it is necessary to understand the various hemostatic procedures, damage control surgery and resuscitation for massive hemorrhage, and systemic management against hypovolemic shock and coagulopathy. In cases of placenta previa with previous cesarean section, the operation should be performed in a tertiary medical facility with well-trained staff and blood availability for transfusion.

Article Synopsis
  • A study examined the effectiveness and safety of common iliac artery balloon occlusion (CIABO) in reducing blood loss during cesarean hysterectomy for patients with placenta previa and accreta.
  • The results showed that the average blood loss in the CIABO group was significantly lower compared to surgery without occlusion or with internal iliac artery ligation.
  • Additionally, the study concluded that CIABO is safe for both mothers and fetuses, with no cases of ischemic necrosis or harmful fetal radiation exposure detected.

Article Synopsis
  • * Researchers analyzed records from 80 patients who received transfusions, comparing several shock indicators, such as estimated blood loss, fibrinogen levels, hemoglobin concentration, and the Japan Society of Obstetrics and Gynecology disseminated intravascular coagulation (JSOG DIC) score, to assess their correlation with transfusion volume.
  • * Findings reveal that while the SI correlates positively with transfusion volume, fibrinogen levels and the JSOG DIC score provide a stronger correlation, suggesting that these indicators

Background. Since cryoprecipitate, fibrinogen concentrate, or recombinant activated factor VII is not approved by public medical insurance in Japan, we retrospectively assessed blood product usage in patients with obstetric hemorrhage at our tertiary obstetric center. Material and Methods.

Aim: Our purpose was to evaluate the effect of internal iliac ligation as a bleeding control during cesarean hysterectomy for placenta accreta.

Methods: We retrospectively reviewed the cases of placenta accreta receiving cesarean hysterectomy during the period of 1987-2006 in the Saitama Medical Center. The clinical outcomes of these patients either receiving or not receiving internal iliac artery ligation were compared in terms of bleeding amount, and length of hospitalization.
