Traumatic vascular injury to the intracranial and extracranial circulation can be sequelae of blunt, penetrating, or iatrogenic insults to the head, face, or neck. Treatment options include conservative medical management, or more invasive surgical or endovascular therapy. ⋯ Need for treatment is partly determined by the collateral circulation to the brain, and the degree to which the lesion is thrombogenic. Advances in endovascular devices and techniques provide us with less invasive alternatives to surgery intervention or allow the interventionalist to treat lesions not treatable by any other modality.

Facial trauma is a commonly encountered injury in the emergency department. Facial fractures can be categorized into limited, transfacial, and smash fractures. ⋯ Smash fractures are comminuted fractures that do not follow classical facial fracture patterns. Depending on the severity of injury, treatment may be conservative or surgical. [figure: see text] Computed tomography is superior to conventional radiography, tomography, and MRI in detecting facial fractures, defining their direction, extent, and displacement.
