ObjectiveTo evaluate outcomes of women undergoing cesarean hysterectomy for abnormal invasive placenta (AIP) with and without preoperative balloon catheter placement in internal iliac arteries.Study DesignA prospective observational study of women with ultrasound diagnosis of AIP and a planned delivery at our institution. From January 2004 to June 2009, all AIP cases were treated with planned multidisciplinary cesarean hysterectomy alone (CHa group). From July 2009 to September 2013 a pre-operative balloon catheter protocol was introduced (BC group). Statistical analysis considered the entire sample (placenta accreta/increta and percreta) and the individual subgroups (accreta/increta vs percreta).ResultsTwenty-three cases of AIP (10 accreta/increta and 13 percreta) were treated with cesarean hysterectomy alone, and 30 cases of AIP (12 accreta/increta and 18 percreta) were treated with cesarean hysterectomy and pre-operative balloon catheters. For the entire sample, a significant difference in estimated blood loss and transfused blood products units was observed between CHa group and BC group. When women with placenta accreta/increta and women with placenta percreta were analysed separately, no difference in estimated blood loss and transfused blood products units was found between the BC and the CHa groups in women with placenta accreta/increta. However, in women with placenta percreta, mean estimated blood loss and transfused blood products units were higher in the CHa group compared with BC group (1507ml vs 933.33ml; 3.31 units vs 0.67 units). Postoperative recovery differed between the two groups, but no differences were observed in any other outcomes.ConclusionsPre-operative placement of intravascular balloon catheters is a feasible treatment for AIP, and is particularly useful in cases of placenta percreta.Copyright © 2014 Elsevier Ireland Ltd.
