Delayed detection of carotid-cavernous fistulas associated with wartime blast-induced craniofacial trauma.

Blast-induced neurotrauma is a leading cause of military casualties. Its effects on cerebrovascular structures are not well understood. Vascular injury resulting from overpressure shock wave impact may have a delayed presentation and detection. The authors present the cases of 2 patients who sustained blast-induced craniofacial trauma and brain injury. Detection of a cervical dissection was delayed in one patient, and detection of carotid-cavernous fistulas was delayed in both patients. The authors report the successful obliteration of both the dissection and the carotidcavernous fistulas via an endovascular approach. Endovascular management provides both a reasonable and effective therapeutic option to blast-induced cerebrovascular injuries.
