Placenta accreta spectrum disorder: a comparison between fertility-sparing techniques and hysterectomy

Abstract

This study aimed to compare fertility-sparing interventions and hysterectomy among women with placenta accreta spectrum disorder (PAS) who underwent caesarean deliveries. We retrospectively reviewed the data, and classified 148 patients as follows: group B: Bakri balloon without resection (n = 83); group R: segmental uterine resection (n = 23); and group H: hysterectomy (n = 42). The groups differed significantly with respect to operative time, transfused blood products, and post-operative intensive care unit and hospital stays. Morbidity was the highest in group H. The aforementioned parameters did not differ between Groups B and R. Groups R and H differed regarding the operative time, post-operative hospital stay, and transfused blood products. Although the treatment modality and PAS severity differed between the groups of patients with preserved fertility, the surgical outcome parameters did not differ. Hence, the effectiveness of these approaches may be similar without foregoing patient safety.

IMPACT STATEMENT

• What is already known on this subject? As caesarean delivery rates have increased worldwide, the incidence of placenta accreta spectrum disorder (PAS), which has high morbidity and mortality rates, has also risen. Planned caesarean hysterectomy is recommended to reduce mortality and morbidity, but fertility is lost.

• What do the results of this study add? The severity of PAS can range from mild to severe. A patient-tailored approach, which was based on the intra-operative findings and used either a Bakri balloon tamponade or segmental uterine resection, reduced morbidity and preserved fertility.

• What are the implications of these findings for clinical practice and/or further research? Instead of adhering to the conventional approach that involves an elective caesarean hysterectomy based on antenatal imaging, more suitable approaches should be considered from the spectrum of haemostatic and fertility-preserving options available, while considering a surgeon’s experience, the intra-operative findings, and patients’ needs.
