Prophylactic Internal Iliac Artery Occlusion Balloon Placement to Reduce Operative Blood Loss in Patients with Invasive Placenta

Abstract

Purpose: To evaluate efficacy and safety of prophylactic internal iliac occlusion balloon placement before cesarean hysterectomy for invasive placenta.

Material and methods: A retrospective analysis was performed of patients with invasive placenta treated with and without occlusion balloon placement. Preoperative occlusion balloons were placed in 90 patients; 61 patients were treated without balloon placement (control group). Baseline demographics, including patient age, gestational age at delivery, gravidity, parity, and number of previous cesarean sections, were not significantly different (P > .05). Of the balloon placement group, 56% had placenta percreta compared with 25% in the control group (P < .001), and 83% had placenta previa compared with 66% in the control group (P = .012).

Results: Median blood loss was 2 L (range, 1.5-2.5 L) in the balloon placement group versus 2.5 L (range, 2-4 L) in the control group (P = .002). Patients with occlusion balloons were transfused a median of 2 U (range, 0-5 U) of packed red blood cells versus 5 U (range, 2-8 U) in patients in the control group (P = .002). In the balloon placement group, 34% had large volume blood loss > 2,500 mL versus 61% in the control group (P = .001), and 21% required blood transfusion > 6 U versus 44% in the control group (P = .002). Eight complications (9%) were attributed to occlusion balloon placement.

Conclusions: Prophylactic internal iliac artery occlusion balloon placement reduces operative blood loss and transfusion requirements in patients undergoing hysterectomy for invasive placenta.
