Spontaneous abdominal aortic rupture from erosion by a lumbar spine fixation device: a case report.

Spontaneous retroperitoneal hemorrhage is an uncommon event. A case of delayed postoperative aortic rupture from erosion by a spinal fixation device, heretofore not previously described, is presented to call attention to this potential catastrophe. Appropriate management includes aggressive patient resuscitation and early surgical intervention with initial proximal and distal control of the aorta, removal of the offending prosthetic appliance, and repair of the vascular injury. Prevention of this complication of vascular erosion by an implanted foreign body requires absolute avoidance of impingement on any medium or large artery.
