Risk Factors for Epidural Hematoma Expansion and the Need for Surgery
The presence of concurrent SAH was the strongest predictor of EDH enlargement, and radiologists should recommend short-term monitoring of patients with EDH and SAH. Repeat CT at 6-13 hours will detect nearly all cases of EDH enlargement, which may lead to subsequent surgery. Initial large size, midline shift, arterial sources of bleeds, and active bleeding imaging findings correlated with an early surgical intervention. Future multicenter studies are needed to refine risk stratification and optimize imaging follow-up to balance patient safety and health care resource use.
