Transcatheter Arterial Embolization for Hemorrhagic Pelvic Fracture: Review Article

Pelvic fractures are severe trauma that can cause hemorrhagic shock. The mortality rate is high when patients fall into shock. Therefore, prompt diagnosis and treatment are necessary. Hemostasis for hemorrhage associated with pelvic fractures is achieved through the mechanical stabilization of the fracture site, preperitoneal pelvic packing, and transcatheter arterial embolization. These techniques are frequently employed in hemodynamically unstable patients presenting with pelvic fractures. Among them, transcatheter arterial embolization is often considered the first-line choice: it is a particularly effective hemostatic method for arterial hemorrhage caused by pelvic fracture. An embolization technique and embolic agents should be considered comprehensively while considering the patient's hemodynamics, angiographic findings, and the urgency of the situation. This article describes the indications, techniques, results, and complications of transcatheter arterial embolization for pelvic fractures.
