We encountered three cases of cervical spinal cord injury with development of clinical evidence of coagulopathy. Hemorrhagic diathesis was diagnosed 2-3 days after the spinal cord injury. Laboratory studies showed decreased fibrinogen and platelet levels, and increases in fibrin degradation products. Although treatment was symptomatic, the laboratory data returned to the normal range after a few days, and no organic dysfunction was observed. We were unable to detect any marked differences between these three cases and other spinal cord injuries with respect to onset, severity or methods of treatment.
