Interventional radiology for critical hemorrhage in obstetrics : Japanese Society of Interventional Radiology (JSIR) procedural guidelines

There has been an increasing demand for interventional radiology (IR) procedures for the treatment of severe postpartum hemorrhage (PPH) (also called critical hemorrhage in obstetrics). The Japanese Society of Interventional Radiology Guideline Committee developed the practical guidelines for IR procedures for severe PPH using evidence-based methodology. This article aimed to describe the rationale for developing these guidelines and to provide the answers for clinical questions about IR procedures consisting of current available evidence and the consensus among experts.
