Traumatic carotid-cavernous fistula: pathophysiology and treatment

Traumatic carotid-cavernous fistulae are rare yet potentially lethal vascular anomalies in the skull base seen after craniomaxillofacial trauma. This aberrant vascular communication has been extensively evaluated and classified, with a number of treatment modalities available to clinicians. The ultimate and definitive treatment of carotid-cavernous fistulae falls beyond the scope of craniomaxillofacial surgery. Nevertheless, clinicians treating patients with craniofacial injuries should have a complete understanding of this pathological entity, because urgent intervention may improve patient outcome.
