Interventional Radiology for Primary Postpartum Hemorrhage: Optimal Strategy Based on the Pathogenesis of Bleeding

抄録

The need for interventional radiology in hemostatic strategies for postpartum hemorrhage has been growing as a reliable and hopeful treatment method because of its non-invasive characteristics, high success rate of hemostatic outcomes, and potential to preserve fertility. Moreover, with the global trend of increasing postpartum hemorrhage, interventional radiology is expected to play an important role. An accurate pre-procedural diagnosis of the underlying cause of bleeding, including tone, trauma, tissue, or thrombin, utilizing contrast-enhanced computed tomography and clinical information, is essential for planning the appropriate technical approach to interventional radiology. This study outlines the fundamental aspects of primary postpartum hemorrhage, compares the computed tomography imaging characteristics associated with various causes, and discusses the appropriate procedural choices of interventional radiology based on the identified etiology.
