Otsuka H, et al. - In order to address the challenge of performing interventional radiology (IVR) in life-threatening trauma settings, researchers practiced and evaluated a trauma-management system with emergency physicians who trained for both severe trauma management, and techniques of surgery and IVR. Findings suggested that IVR could be the best first measure for resuscitative hemostasis in some cases with potentially lethal multiple injuries, given efficient diagnoses/actions and the ability to deal with complications.
