Role of Interventional Radiology in Pregnancy Complicated by Placenta Accreta Spectrum Disorder: Systematic Review and Meta-analysis

摘要

The increase in cesarean sections performed in the last 20 years has also led to a large increase in the incidence of placenta accreta spectrum (PAS) disorders. Prenatal diagnosis of a PAS disorder, by ultrasound or magnetic resonance imaging, has been shown to improve maternal outcome by letting providers plan surgical treatment for these disorders. The best surgical approach to PAS disorders, however, has not been determined and there has been no randomized controlled trial comparing the management options. Endovascular interventional radiology (IR) procedures are used for postpartum hemorrhage of various etiologies, and while there has been some evidence a role for IR in reducing maternal mortality, there are mixed results on the use of IR in improving surgical outcome for PAS disorder pregnancies.The researchers sought to evaluate the potential benefit of IR in improving outcomes for women who undergo surgery for a PAS disorder.
