When pelvic trauma leads to ongoing bleeding after initial stabilization, the priority is stopping arterial hemorrhage. External fixation helps stabilize the pelvic ring and can reduce venous bleeding, but it doesn’t reliably control arterial bleeding. Angiographic embolization uses interventional radiology to locate and occlude the bleeding vessel, offering targeted, definitive control of arterial hemorrhage with less invasiveness than open surgery. Surgical exploration in the retroperitoneum is not a first-line solution for pelvic arterial bleeding and carries high risks and limited effectiveness for stopping such hemorrhage. Observation isn’t appropriate when active bleeding persists. Therefore, angiographic embolization is the most appropriate intervention in this scenario.
