Endovascular Treatment Following Gauze Packing for the Control of Massive Bleeding from Traumatic Transverse Sinus Lesion.

Posterior fossa epidural hematoma (EDH) is uncommon, but the related clinical deterioration can occur suddenly. Accompanying venous sinus injury and lacerations are associated with 40% to 80% mortality. The authors present one clinical case of a patient with posterior fossa EDH from transverse sinus bleeding. A 57-year-old male was injured after falling while working. He was taken to the hospital, where computed tomography scans of his brain revealed a right posterior temporal and cerebellar EDH with a right temporo-occipital fracture. He underwent a right parieto-occipital craniotomy, incorporating the fracture line. Longitudinal laceration of the right transverse sinus extending to the sigmoid sinus with profuse bleeding was identified. Four gauzes were inserted in the epidural space for tamponade of the injured sinus. Conventional angiography and coil embolization for the injured sinus were immediately performed. Subsequently, the patient was transferred to the operating room, wherein staff members removed the gauzes and remnant hematoma. Based on this experience, the authors recommend that for posterior fossa EDH from transverse sinus bleeding, bleeding control should be performed by gauze packing and endovascular treatment.
