title: Prophylactic bilateral internal iliac artery balloon occlusion in the management of placenta accreta: A 36-month review.
abstract: The contemporary obstetrician is increasingly put to the test by rising numbers of pregnancies with morbidly adherent placenta. This study illustrates our experience with prophylactic bilateral internal iliac artery occlusion as part of its management.
  
  
  
  Between January 2011 to January 2014, 13 consecutive patients received the intervention prior to scheduled caesarean delivery for placenta accreta. All cases were diagnosed by ultrasonography, color Doppler imaging and supplemented with MRI where necessary. The Wanda balloon(TM) catheter (Boston Scientific, Natick, MA, U.S.A) were placed in the proximal segment of the internal iliac arteries preceding surgery. This was followed by a midline laparotomy and classical caesarean section, avoiding the placenta. Both internal iliac balloons were inflated just before the delivery of fetus and deflated once haemostasis was secured. Primary outcomes measured were perioperative blood loss, blood transfusion requirement and the need for ICU admission.
  
  
  
  The mean and median intraoperative blood loss were 1076mls±707 and 800mls (300-2500) respectively while mean perioperative blood loss was 1261mls±946. Just over half of the patients in our series required blood and/or blood products transfusion. Two patients (15.4%) required ICU admission.
  
  
  
  Our study suggests that preoperative prophylactic balloon occlusion of bilateral internal iliac arteries reduces both blood loss and transfusion requirement in patients with placenta accreta, scheduled to undergo elective caesarean hysterectomy. It is an adjunct to be considered in the management of a modern day obstetric problem, although the authors are cautious about generalizing its benefit without larger, randomized trials.
