Bilateral multiple cervical root avulsions without skeletal or ligamentous damage resulting from blast injury: case report.

OBJECTIVE AND IMPORTANCE: We describe a unique case of multiple bilateral cervical root injuries without ligamentous or bony injury secondary to a sandblast accident. CLINICAL PRESENTATION: A 19-year-old man sustained a sandblast injury to his face, neck, chest, and upper extremities, with immediate loss of motor and sensory function occurring in both of his upper extremities. Cervical spine x-rays, computed tomography, and magnetic resonance imaging demonstrated no fracture, soft tissue abnormality, or malalignment. The restriction of deficits to the patient's upper extremities suggested a central cervical spinal cord injury, bilateral brachial injuries, or a conversion disorder. INTERVENTION: Cervical computed tomographic myelography revealed multiple bilateral nerve root injuries. CONCLUSION: This case report is unique in the literature in that it describes a patient with multiple cervical nerve root injuries secondary to sandblast injury without ligamentous or bony injury. Although magnetic resonance imaging remains the diagnostic modality of choice in patients with acute spinal cord injury, it is deficient in demonstrating cervical root injury in the acute setting. In this setting, computed tomographic myelography is superior.

Recombinant activated factor VII for cerebral injury-induced coagulopathy in pediatric patients. Report of three cases and review of the literature.

Brain injury remains one of the leading causes of death and disability in children. Appropriate therapy involves aggressive management of intracranial pressure (ICP) and cerebral perfusion pressure, which often requires placement of an intraparenchymal ICP monitor or intraventricular catheter. These potentially life-saving interventions require normal coagulation function; however, several factors may lead to coagulopathy in the head-injured patient. Standard therapies, which often include multiple doses of fresh frozen plasma (FFP), have a number of drawbacks when used in the pediatric population. The use of FFP requires time to type and crossmatch, thaw, and administer. It imposes a significant volume load on a child in whom cerebral edema remains a problem. Success in using recombinant activated factor VII (rFVIIa) in the hemophiliac population suggests an alternative therapy. Three patients suffered severe coagulopathy after cerebral injury. One patient received rFVIIa after repeated doses of FFP had failed to correct the coagulopathy; the other two patients received rFVIIa as the initial therapy. Treatment with rFVIIa consisted of a bolus of 90 microg/kg. Recombinant activated factor VII rapidly corrected the patients' coagulopathies, which allowed placement of intraparenchymal fiberoptic lines and intraventricular catheters to monitor ICP. The patients suffered no complication from the placement of ICP monitoring devices, as demonstrated on computerized tomography scans obtained within 24 hours after placement. Brain injury-induced coagulopathy may lead to significant secondary injury and delays the invasive monitoring necessary for the aggressive management of intracranial hypertension. Fresh frozen plasma takes time to administer. may require repeated doses of significant volume for the pediatric patient, and may ultimately fail. Preliminary data indicated that rFVIIa provides a rapid and successful correction of coagulopathy in the head-injured patient.
