Management of Venous Sinus-Related Epidural Hematomas.

ABSTRACT

BACKGROUND: Epidural hematomas (EDHs) involving the venous sinuses are uncommon and carry the risk of hemorrhage or venous infarction. We report the largest case series for superior sagittal sinus- and transverse sinus-related EDHs including surgical and nonsurgical management. We compare our findings to the relevant literature. METHODS: A retrospective review of the EDH cases at our center was performed from 2013-2018. Patients were analyzed by surgical versus conservative management, outcomes, and complications. RESULTS: Of the 268 EDH patients identified, 32 involved the venous sinuses (23 supratentorial and 9 infratentorial). Ten of the patients had surgery, and 22 were managed conservatively. No surgical complications occurred, and all had a Glasgow Outcome Scale score of 5 at follow-up. All of the nonsurgical patients had a Glasgow Outcome Scale score of 4 or 5 at follow-up except for 1 patient with prior disability. The literature search resulted in 39 infratentorial and 47 supratentorial EDHs involving venous sinuses. CONCLUSIONS: Surgical and nonsurgical management of EDHs involving the venous sinuses are both viable options with good outcomes. Surgical intervention is based on location, size, neurologic examination, expansion on serial imaging, and vascular imaging findings. Surgery has the potential for significant complications, but all surgical patients in our series had good outcomes at follow-up. Similarly, nonsurgically managed patients had good outcomes and our overall series demonstrates better outcomes with fewer complications than other similar series in the literature.
