Penetrating craniocerebral injuries in the Israeli involvement in the Lebanese conflict, 1982–1985

Abstract

✓ From June, 1982, through June, 1985, 113 patients were evacuated to Rambam Maimonides Medical Center with penetrating craniocerebral injuries sustained in ongoing military hostilities in Lebanon. Two factors distinguished this group of patients from those presenting in earlier conflicts: 1) this was the first large series in which computerized tomography (CT) was routinely used to initially evaluate combat head injuries; and 2) in an effort to preserve maximum cerebral tissue, intracranial debridement was significantly less vigorous than that advocated during the Korean or Vietnam conflicts. No efforts were made to locate or remove indriven bone or metal fragments visualized on CT unless they readily presented themselves on gentle irrigation. In fact, it was elected to treat a number of patients without intracranial hematomas nonoperatively. The acute outcome was quite similar to that reported in Vietnam series in respect to both complications and mortality. Of the 83 survivors, 46 were Israeli citizens and thus were available for follow-up review. These 46 patients were reevaluated in late 1988, a mean follow-up period of 5.9 years. None had died in the interim; 10 had developed chronic seizure disorders, and there was one case of delayed meningitis in a patient with no retained fragments. Repeat CT scans were performed on 43 patients; 22 (51%) were found to have retained intracranial bone fragments. No relationship existed between the presence of retained fragments and the development of either a seizure disorder or an infection of the central nervous system. These findings suggest that not only is it unnecessary to reoperate for retained bone fragments, but it may also be possible to temper the initial debridement in an effort to preserve additional cerebral tissue.
