Exchange of intraoperative balloon occlusion of the internal iliac artery for the common iliac artery during cesarean hysterectomy in a patient with placenta percreta

PATIENT Female, 36 FINAL DIAGNOSIS: Pregnancy - placenta increta Symptoms: - MEDICATION - Clinical Procedure: Cesarean hysterectomy Specialty: Obstetrics and Gynecology. OBJECTIVE Unusual clinical course. BACKGROUND The generally accepted treatment for placenta percreta is cesarean hysterectomy without attempts to detach the placenta. Preoperative internal iliac artery balloon occlusion (IIABO) has been widely performed to minimize blood loss during cesarean hysterectomy for an abnormal attachment of the placenta. Our case is the first reported case of common iliac artery balloon occlusion (CIABO) being more effective than IIABO for reducing blood loss during a cesarean hysterectomy in the same patient. CASE REPORT We performed cesarean hysterectomy with IIABO in a 36-year-old Japanese female who had placenta percreta. However, there was still a large amount of blood loss. We immediately changed the balloon from the internal iliac artery to the common iliac artery, which visibly reduced the amount of blood loss. We finally achieved cesarean hysterectomy. CONCLUSIONS CIABO was found to be more effective than IIABO for reducing blood loss during cesarean hysterectomy. Failure of IIABO can be explained by the presence of extensive anastomoses in the pelvic vasculature.
