Disseminated intravascular coagulation (DIC) is reported in neurosurgical patients; however, the incidence of DIC after craniotomy procedures is unknown. Using a surgical database, we identified 3164 patients who underwent primary craniotomy at Mayo Clinic Rochester between January 1, 2000 and December 31, 2004. Potential cases of DIC in this population were identified using 3 search triggers, patients: (1) in whom the diagnosis of DIC was noted on their hospital discharge summary, (2) who received red blood cell-free blood products, or (3) in whom a blood fibrinogen or d-dimer concentration was assessed. ⋯ Although this small sample of patients receiving salvaged blood requires caution in interpreting the results, the risk of DIC seemed to be greater with salvaged blood than without [odds ratio 24 (CI=2.5-237)]. In children, 2 of 3 patients who developed DIC had congenital malformations of the brain. Findings from this study suggest that DIC is rare after craniotomy, but is often associated with mortality.
