“…Studies that have been done of angiography/embolization are difficult to directly compare with PPP because indications for intervention for pelvic fracture related hemorrhage or angiography vary from institution to institution; for example, some institutions send every unstable patient with a pelvic fracture directly to angiography, while some patients are excluded with a positive FAST; other institutions only send patients with a positive blush on CT scan, a large pelvic hematoma, or persistent hypotension [8, 9, 15•, 28, 37•, 45, 47•, 48, 49]. It has been recognized that a blush on CT scan is not a specific indicator of need for angioembolization [11]. While there is a role for angioembolization, there are potential deterrents to using this as a first-line treatment.…”
