Background: The objective of this study was to evaluate the efficacy of
intraoperative aortic balloon occlusion (IABO) during caesarean section for
placenta accreta, increta or percreta and explore the relationship between
different profile balloon catheters and catheter-related complications.
Methods: This retrospective case control study included 295 patients
with pathologically confirmed placenta accreta spectrum (PAS) disorder at the
Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital
between 2013 and 2019. The characteristics of 162 patients who had aortic balloon
occlusion (balloon group) were compared with those of 133 patients who had no
catheterization (control group). Results: There were significant
differences between the two groups in estimated blood loss, calculated blood
loss, number of transfusions, transfused packed red blood cells (PRBCs),
haemoglobin reduction, operation time and caesarean hysterectomy (P
