Background: The placenta accreta spectrum is a complex disorder characterized by abnormal invasion of the placenta into the uterine wall, posing a significant risk of life-threatening haemorrhage for patients. Its incidence is on the rise, largely attributed to the increasing rates of caesarean sections. Management of this spectrum involves a multidisciplinary approach, although standardized protocols are not yet established. While caesarean hysterectomy remains the standard Gold, several adjunctive treatments have emerged in recent years to mitigate bleeding risk and associated morbidity. Among these, prophylactic occlusion balloons placed in the internal iliac arteries have shown promise. The aim of our study is to demonstrate the effect of prophylactic occlusion balloons in both uterine iliac arteries in the management of placental accreta spectrum disorders. Methods: A retrospective monocentric cohort study was conducted in the Department ''C'' of Gynaecology and Obstetrics at the Maternity Center of Tunis. The study spanned three years, from January 2nd, 2020, to December 31st, 2022. The study population consisted of two groups: Control Group (CG) comprised patients who underwent caesarean hysterectomy without internal-iliac prophylactic occlusion balloons, and Occlusion balloons of both internal iliac arteries Group (OBIIAG) included patients who underwent caesarean hysterectomy with internal-iliac prophylactic occlusion balloons. Results: A total of 38 patients were included in the study, all of whom exhibited similar epidemiological characteristics and comparable personal and obstetric histories. The most prevalent risk factor among the patients was a history of caesarean section (92%). On average, patients were diagnosed at 30 weeks of gestation, with third-trimester bleeding being the most common presentation (71% of cases). The median gestational age at delivery was between 36 and 37 weeks. We observed a significant difference in blood loss between the two groups (2888 ml in the control group and 1828 ml in the group with internal-iliac prophylactic occlusion balloons, p < 0.05). Implementation of this technique resulted in a reduced need for massive transfusions (p < 0.01) and shorter operating times (126 min for the control group and 92 min for the group with internal-iliac prophylactic occlusion balloons; p = 0.04). There were no significant differences in morbidity between the two groups. Conclusion: The intra-iliac prophylactic occlusion balloons can help reduce the risk of hemorrhage and the morbidities that come with the placenta accreta spectrum disorder.
