Interventional Radiology Role in Conservative Management of Placenta Accreta Spectrum: A Narrative Review

Placenta accreta spectrum (PAS) is a significant obstetric complication characterized by abnormal placental attachment and invasion into the myometrium, leading to severe risks during delivery, including substantial hemorrhage. This systematic review the evolving role of interventional radiology (IR) in the conservative management of PAS. It highlights various IR techniques, including pelvic arterial embolization, pre-operative arterial access with intra-operative embolization, and balloon occlusion methods. Those innovative techniques can effectively control hemorrhage, reduce the need for hysterectomy, and preserve fertility in appropriately selected PAS patients. The review underscores the importance of a multidisciplinary approach and individualized management strategies to optimize patient outcomes in this challenging obstetric condition.
