“…Previous studies revealed anterior placentation and complete placenta previa as independent risk factors for massive hemorrhage during CS (9,10,26); however, in the present study, they were not associated with significant hemorrhage possibly due to the added value of occlusion of the blood supply to the uterus and placenta by the UAE procedure.…”

“…Placenta percreta is the most severe form of abnormal placental adherence, and the incidence is the lowest, accounting for only 7% of placenta invasion (26). The patient always experiences a significant hemorrhage during delivery when placenta removal is attempted.…”

AimsWe investigated whether common iliac artery balloon occlusion (CIABO) was effective for decreasing blood loss during cesarean hysterectomy (CH) in patients with placenta previa with accreta and was safe for mothers and fetuses.MethodsOf the 67 patients who underwent CH for placenta previa with accreta at our facility from 1985 to 2014, 57 patients were eligible for the study. The amount of intraoperative bleeding during CH was compared between three groups: surgery without blood flow occlusion (13 patients), internal iliac artery ligation (15 patients) and CIABO (29 patients). Additionally, multivariate analysis was performed to assess risk factors for massive bleeding during CH.ResultsThe mean blood loss in the CIABO group (2027 ± 1638 mL) was significantly lower than in the other two groups (3787 ± 2936 mL in the no occlusion, 4175 ± 1921 mL in the internal iliac artery ligation group; P < 0.05). Multivariate analysis showed that spontaneous placental detachment during surgery (odds ratio [OR] 49.174, 95% confidence interval [CI] 4.98–1763.67), a history of ≥ 2 cesarean sections (OR 9.226, 95% CI 1.07–231.15) and no use of CIABO (OR 26.403, 95% CI 3.20–645.17) were significantly related to massive bleeding during surgery. There was no case of necrosis resulting from ischemia. The mean radiation dose during balloon placement never exceeded the threshold value for fetal exposure.ConclusionBleeding during CH for placenta previa with accreta can be decreased by CIABO. This study also confirmed the safety of CIABO in regard to maternal lower limb ischemia and fetal radiation exposure during balloon placement.

“…The incidence has increased sharply from 1 in 533 pregnancies for the periods of 1982-2002 to 1 in 4 027 pregnancies in the 1970s, and to 1 in 2 510 pregnancies in the 1980s. [3][4][5] In a 2015 review of birth registries, Mehrabadi et al, noted an incidence of placenta accrete of 14.4 per 10 000 deliveries. 6 Myometrial damage caused by a previous caesarean delivery with either anterior or posterior placenta previa overlying the uterine scar contribute the greatest risk for developing placenta accrete.…”

Morbidly adherent placenta (MAP) can be divided into placenta accrete, placenta increta and placenta percreta. It is associated with high parity, multifetal gestation, advanced maternal age, assisted reproductive technologies, placenta previa, and more importantly a history of caesarean section or uterine surgery. Globally, the incidence of placenta accrete has increased and seems to be in parallel with the increasing rate of caesarean section delivery.Despite rapidly evolving diagnostic imaging, and growing of surgical expertise, morbidly adherent placenta (MAP) remains an important cause of maternal morbidity and mortality, especially related with life-threatening postpartum haemorrhage. Although the choice of treatment for placenta accrete is puerperal hysterectomy, this procedure itself involves a greater risk of intra-operative haemorrhage.Elective caesarean hysterectomy using prophylactic bilateral internal iliac artery balloon occlusion offer an interesting approach which can minimize the risk of intra-operative haemorrhage. However, our case report describes the case of a 28-year old Gravida 3 Para 2 morbidly obese parturient diagnosed to have placenta previa type 3 posterior with accrete who experienced a complication of life threatening massive bleeding post-operatively after an elective caesarean hysterectomy using a prophylactic bilateral internal iliac artery balloon occlusion intra-operatively.
