High grade occlusion of the iliac vein by a traumatic pelvic hematoma without fracture.

A case of a man with a massive pelvic hematoma from blunt trauma without bony fracture is presented. The pressure of the hematoma on the iliac vein prevented fluid resuscitation using this route. A pelvic hematoma should be suspected in patients with iliac vein obstruction after blunt pelvic trauma even in the absence of fractures.
