ABSTRACT
Objective To study the operative technique and effect of temporary balloon occlusion of the abdominal aorta for preventing intraoperative bleeding during cesarean for patients with pernicious placenta previa and placenta accreta. Methods Retrospective analysis was conducted on the intraoperative situation of forty-one cases and information of follow-up twenty-nine cases, which were pernicious placenta previa and placenta accreta and delivered in the First Affiliated Hospital of Zhengzhou University from May 1, 2013 to June 30, 2014. Diagnosis was confirmed by line of color Doppler ultrasound and MRI for all patients before operations. An interventional physician performed right femoral artery puncture and preset the abdominal aortic balloon catheter in the digital subtraction angiography operation room before cesarean. At the same time of fetal delivery, 10 ml normal saline was injected into the balloon immediately, which results in filling of the balloon and blocking of the aorta. According to the area and depth of placenta implantation and implantation or penetration of the posterior bladder wall, placenta separation, partial resection of the uterine wall and partial bladder resection and repair were performed correspondingly. Meanwhile, saline in the balloon was pumped out gradually until empty. Condition of placenta implantation, blood loss and blood transfusion volume during the operation, intraoperative and postoperative complications, the duration and dose of fetal radiation exposure, and Apgar score of neonates were analyzed. Results Among the 41 cases, penetrative placenta and implanted placenta were observed in five cases and 36 cases, respectively. The latter 36 cases including 28 cases of bladder posterior wall accreta and eight cases of bladder posterior wall penetration. For all cases, the average operation time was (68.5±15.3) min, the mean blood loss in the operation was (1 058±960) ml, among which eight received blood transfusion with an average of (600±400) ml, and the mean hospital stay was (8.2±2.3) d. Uteruses were reserved in all cases. The mean duration and dose of fetal radiation exposure was (8.1±3.6) s and (5.2±2.9) mGy, and the Apgar score of neonates was 8.7±0.5 at 1 min and 9.5±0.3 at 5 min, respectively. The patients were followed up until October 31, 2014. Among them, six were lost, six were still in puerperium, 18 were breast-feeding, and the menses of 11 had returned. Conclusion Preset abdominal aortic balloon catheter in pernicious placenta previa and placenta accrete patients might effectively reduce the blood loss during cesarean section as well as the risk of hysterectomy through temporary occlusion of the abdominal aorta.
