Clinical indications for arteriography in pelvic trauma
The pelvis represents a very large potential space, often able to accommodate 4 to 5 L of blood. Traumatic diastasis of the symphysis pubis can double the effective potential space of the pelvis. Pelvic bleeding can be difficult to control surgically. Splinting and external fixation are usually performed first to help reduce bleeding. Indications for arteriography include open pelvic fracture, expanding pelvic hematoma, and transfusion requirement greater than 4 U over 24 hours.
