Background: To compare the efficacy of temporary abdominal aortic occlusion with internal iliac artery occlusion for the management of placenta accreta.
Patients and methods: 105 patients with placenta accreta were selected for treatment with temporary abdominal aortic occlusion (n = 57, group A) or bilateral iliac artery occlusion (n = 48, group B). Temporary abdominal aortic and internal iliac artery balloon occlusions were performed during caesarean sections. Data regarding the clinical success, blood loss, blood transfusion, balloon insertion time, fluoroscopy time, balloon occlusion time, foetal radiation dose, and complications were collected.
Results: Temporary abdominal aortic occlusion and bilateral internal iliac artery occlusion were technically successful in all patients. The amount of blood loss (P < 0.001), amount of blood transfusion (P < 0.001), balloon insertion time (P < 0.001), foetal radiation dose (P < 0.001) and fluoroscopy time (P < 0.01) in group A were significantly lower than those of patients in group B. No marked differences were found between these 2 groups with respect to age, mean postoperative hospital stay, balloon occlusion time, and Apgar score (p > 0.05).
Conclusions: Temporary abdominal aortic balloon occlusion resulted in better clinical outcomes with less blood loss, blood transfusion, balloon insertion time, fluoroscopy time and foetal radiation dose than those in bilateral internal iliac balloon occlusion. .
