1.Introduction
External iliac artery injury from a penetrating pelvic trauma although
rare can result in a life-threatening hemorrhage and death in up to 60%
of cases [1,2] . This type of injury is often associated with
simultaneous injuries of surrounding structures but rarely with bladder
injury. The formation of an acute ilio-vesical fistula or shunt as an
immediate complication of both the external iliac artery and bladder
injuries is extremely rare [1,2,3]. Of the few reported cases of
external iliac artery and bladder fistuli only 4 are related to pelvic
gunshot wounds with only 1 diagnosed at index presentation with an
obvious external iliac artery injury and the other 3 diagnosed later as
a result of posttraumatic external iliac pseudoaneurysm rupture into the
bladder [1,2,4] .
