Optimal management of cervical cord injury in the presence of documented instability and/or compression of neural elements remains a controversial topic. Surgery and internal stabilization of cervical spine fracture/dislocations are effective and well accepted, but controversy exists on the relative merits of the anterior versus the posterior approach as well as the optimal timing of surgical intervention. We report our experience with the Caspar technique and instrumentation for anterior stabilization in 54 patients for acute cervical spine injury. ⋯ Because this route has the potential for more serious complications, it should be reserved for the cases in which anterior decompression is deemed necessary or posterior fusion was unsuccessful. With appropriate selection of patients, no adverse effect of early surgery was demonstrated. In fact, neurologically compromised patients had the benefits of increased ease of patient care and early transfer to rehabilitation.

Case Reports
Traumatic carotid-cavernous sinus fistula associated with an intradural pseudoaneurysm: a case report.
A case of traumatic carotid-cavernous sinus fistula (CCF) associated with an intradural pseudoaneurysm is reported. A 42-year-old man developed traumatic CCF after severe head trauma. Cerebral angiography demonstrated a direct CCF associated with an intradural pseudoaneurysm at the C2 portion. ⋯ A CCF with an intradural pseudoaneurysm is life-threatening and requires emergency treatment. However, balloon occlusion in such cases is contraindicated because of possible rupture of a pseudoaneurysm. Trapping or a direct surgical approach is the treatment of choice.

Analysis of 314 cases of penetrating craniocerebral missile injuries in civilians revealed a high rate of early mortality, with 228 victims having died at the scene and a further 38 dead within 3 hours. Surgery was performed in 44 patients who had a preoperative Glasgow Coma Score of at least 4. ⋯ Vigorous resuscitation and early surgery often resulted in useful survivals and occasionally in spectacular recoveries. However, the high mortality rate on the scene or soon after the injury restricted the possibility of effective management to a minority of cases.

Review Case Reports
Brain abscess associated with congenital pulmonary arteriovenous fistula.
A case of brain abscess associated with congenital pulmonary arteriovenous fistula was presented and 52 reported cases were reviewed. The brain abscess was successfully treated with repeated aspiration and drainage, and the pulmonary arteriovenous fistula, located in the right lower lobe, was resected. ⋯ Brain abscesses can be an initial clinical manifestation in asymptomatic pulmonary arteriovenous fistula. This possible association should be borne in mind in cases of brain abscesses of unexplained etiology.

The authors have developed and patented a neurosurgical retractor system incorporating an infrared emitter and detector that allows detection of cerebral pulsations. Gentle contact with the surface of cat brains shows cerebral pulsations that correlate with arterial pulse as well as mechanical ventilation. ⋯ The pressure on the surface of the brain decreased 50% in 5 minutes even though the position of the retractor was maintained constant. The authors postulate that monitoring cerebral pulsation may prove useful in clinical neurosurgery with respect to avoiding excessive retraction, which causes brain damage.
