✓ Elevation of systemic arterial pressure in seven patients with intracranial arterial aneurysms has been shown to be effective in alleviating ischemic symptoms attributed to cerebral vasospasm. Autoregulation is at least partially lost in patients with cerebral hemodynamic crisis. Blood volume expansion was used to augment vasopressors in maintenance of systemic hypertension. The management of these cases is discussed. Caution in the use of this technique is advised, since the regimen is not without risk.

✓ The history, physical findings, and treatment of dural arteriovenous malformations are reviewed. The importance of completely identifying and obliterating the fistula, even at the expense of obliterating major venous sinuses, is emphasized. Failure of surgical treatment usually is the result of mistaking the more obvious dilated feeding vessels for the lesion itself.

Pediatric neck injuries

A clinical study

Stephen A. Hill, Carole A. Miller, Edward J. Kosnik and William E. Hunt

✓ This review of pediatric neck injuries includes patients admitted to Children's Hospital of Columbus, Ohio, during the period 1969 to 1979. The 122 patients with neck injuries constituted 1.4% of the total neurosurgical admissions during this time. Forty-eight patients had cervical strains; 74 had involvement of the spinal column; and 27 had neurological deficits. The injuries reached their peak incidence during the summer months, with motor-vehicle accidents accounting for 31%, diving injuries and falls from a height 20% each, football injuries 8%, other sports 11%, and miscellaneous 10%.

There is a clear division of patients into a group aged 8 years or less with exclusively upper cervical injuries, and an older group with pancervical injuries. In the younger children, the injuries involved soft tissue (subluxation was seen more frequently than fracture), and tended to occur through subchondral growth plates, with a more reliable union than similar bone injuries. In the older children, the pattern and etiology of injury are the same as in adults. The entire cervical axis is at risk, and there is a tendency to fracture bone rather than cartilaginous structures.
