[Extradural hematoma in the Emergency Medical Assistance System and scanners. Comparison between 2 series at the Sainte-Anne Hospital Center]. / L'hématome extra-dural à l'ère du S.A.M.U. et du scanner. Comparaison de deux séries du Centre Hospitalier Sainte-Anne.

The authors compare two groups of intracranial epidural hematomas treated in the Neurosurgical department of Sainte-Anne Hospital in Paris: the first group includes 262 patients operated upon between 1965 and 1977; the second group concerns 124 patients operated during the period 1979-1984. The mortality rate has been progressively diminishing from 1969 (50%) to 1984 (12.5%). Among the survivors, functional sequellae are still frequent; some improvement in the functional prognosis has although been noted; in the first group, 41% of patients are cured and 56% of them returned to work; in the second group, 50% are cured, and 62% returned to their professional activities. The detailed analysis of those data emphasizes the importance of CT-Scan and of the improvement of specialized neurosurgical intensive care; on the other hand, the particular role of an emergency care organisation, such as the SAMU, appears rather discreet referring to this type of pathology.
