Staged Treatment of the Placenta Accreta Spectrum: A Combined Surgical and Radiologic Approach

Abstract

(Aust N Z J Obstet Gynaecol. 2023; 63: 372–377) The placenta accreta spectrum (PAS) is defined by aberrant placental invasion into the uterine myometrium. Globally, the prevalence of PAS is rising, which affects maternal health outcomes. The depth of invasion into the uterus determines how it is classified, with placenta accreta (villi connecting to the muscle layer), placenta increta (myometrial invasion), and placenta percreta (transmural invasion beyond the serosa) being the most severe. This study evaluated maternal and neonatal outcomes following a combined surgical and interventional radiology (IR) approach for managing the PAS.
