ABSTRACT

OBJECTIVE:

Patients undergoing intracranial operations often suffer from post-operative epidural hematoma (EDH). The incidence and risk factors for with the occurrence of EDH after intracranial operations are not well described previously. The objective of this study was to identify the risk factors and the incidence of post-operative EDH adjacent and regional to the craniotomy.

METHODS:

This was a retrospective study of 23 (2.4%) patients, between January 2005 and December 2011, who underwent epidural hematoma evacuation after primary intracranial during this period, 941 intracranial operations were performed. The control group (46 patients) and hematoma group (23 patients) were categorized on the basis of having undergone the same pre-operative diagnosis and treatment within 3 months of their operations. The ages of the hematoma and control group were individually matched to similar ages within 10 years of each other to minimize bias of age.

RESULTS:

Univariate analysis showed that the significant pre-operative and intra-operative factors associated with post-operative EDH were a pre-operative Glasgow Coma Scale (GCS) scored 1.0 (p=0.014), prothrombin time (PT) >11.3 sec (p=0.008), intra-operative blood loss >650 mL (p=0.003) and craniotomy size >7,420 mm2 (p=0.023). In multivariate analysis, intra-operative blood loss exceeding 650 mL (median of total patients) placed a patient at significantly increased risk for post-operative EDH.

CONCLUSION:

Recognizing the limitations of the study, large intra-operative blood loss, wide craniotomy area, prolonged PT and a pre-operative GCS <8 are presented implicated with an increased risk of post-operative EDH after intracranial surgery.
