The incidence of placenta accreta ( PA ) has markedly increased in the United States, from 1/30 000 in 1950 to 1/731 deliveries in 2011. Although placenta praevia after prior caesarean sections ( CS ) is the most important risk factor for PA , other risk factors make up 1–5% of PA occurrences. At our referral hospital, we use the pre‐caesarean prophylactic balloon catheter with or without post‐surgery embolisation in a hybrid room. Here, we evaluate the role of prior CS and placenta praevia on the outcome of this procedure. Materials and Methods This retrospective cohort analysis included 61 women during the years 2004–2016 with sonographic suspicion of PA who underwent balloon catheterisation prior to CS . Results Eleven women had no previous CS (18%). Mean previous CS rate was 1.85. Six women (9.8%) had previous dilatation and curettage (D&C); 36.4% of women with no previous CS had previous D&C compared with 4% of women with previous CS ( P = 0.008). Placenta praevia was sonographically diagnosed in 55 women (90.2%). There was a higher rate of caesarean hysterectomy in women with previous CS than in those without (32% vs 0%, P = 0.052) but no significant difference in blood product requirements (45.5% vs 66%, P = 0.303). There was no significant difference in hysterectomy rate, blood transfusion or surgery duration between women with and without placenta praevia ( P = 0.648, 0.594, 0.995, respectively). Conclusion Previous CS rather than placenta praevia is a strong indicator of hysterectomy in cases of PA . Different risk factors for PA do not affect blood transfusion rates or surgery duration.
