Objectives
The aim of this study is to evaluate the efficacy of prophylactic internal iliac artery balloon occlusion combined with Pituitrin intra-arterial infusion in the control of postpartum hemorrhage in women with placenta accreta spectrum (PAS).
Methods
This is a prospective and non-randomized controlled study. The participants were assigned into three groups: without balloon catheterization (non-BC) group, balloon catheterization (BC) group, and Pituitrin combined with balloon catheterization (PBC) group. The primary outcomes were estimated blood loss (EBL) and the units of transfused packed red blood cells (PRBC). The secondary outcome was the incidence of hysterectomy.
Results
A total of 100 participants were recruited between August 2013 and November 2018 and assigned into the respective groups as follows: 27 in the non-BC group, 22 in the BC group, and 51 in the PBC group. No statistical differences were found in demographic characteristics among the three groups. There was a trend of lower EBL, PRBC, and hysterectomy rate in the BC group than those in the non-BC group, while all values showed no significant differences (all p > 0.05). Patients in the PBC group had significantly lower EBL, PRBC, and hysterectomy rate compared with those in the non-BC group (all p < 0.05). Linear regression analysis revealed that the PBC (vs. others) was negatively correlated with EBL and the non-BC (vs. others) independently predicted more EBL.
Conclusions
Balloon occlusion combined with Pituitrin infusion is an effective treatment method which significantly reduced EBL, PRBC, and hysterectomy rate in patients with PAS.
Key Points
• Internal iliac artery balloon occlusion combined with Pituitrin intra-arterial infusion can significantly decrease EBL, PRBC, and hysterectomy rate during cesarean section in patients with PAS.
• Cesarean section without balloon occlusion and placenta accreta depth are two independent risk factors for EBL in patients with PAS.
