Placenta accreta and balloon catheterization: the experience of a single center and an update of latest evidence of literature.

PURPOSE: We studied the efficacy of using pre-cesarean delivery (CD) temporary occlusion of internal iliac arteries with balloon catheters in case of placenta previa-accreta in terms of maternal and neonatal outcomes and to test accuracy of ultrasound (US) and magnetic resonance imaging (MRI) for prenatal diagnosis.

METHODS: From March 2014 to January 2018, women with an US and/or MRI diagnosis of placenta previa-accreta and a planned delivery were enrolled and divided into two groups: balloon catheterization group (women treated with preoperative catheters and CD) and control group (women candidates to elective CD).

RESULTS: 37 patients were enrolled: 16 in balloon catheterization group and 21 in control group. Significant differences were detected in estimated blood loss. Prophylactic balloon catheterization could reduce intraoperative red blood cell transfusion. The incidence of hysterectomy was lower in balloon group. No statistical difference was found for neonatal outcomes. Both US and MRI have showed to be useful and complementary to diagnose placenta previa-accreta.

CONCLUSIONS: Temporal, perioperative, and prophylactic positioning of balloon vascular catheters is an effective method for managing severe hemorrhage caused by placenta previa-accreta as it reduced intraoperative blood loss, lessened perioperative hemostatic measures and intraoperative red cell transfusions, and reduced hysterectomies.
