“…Simulated head injury in animals has been shown to produce narrowing of the exposed basilar artery ~ as well as the perforat-ing arteries of the cerebral cortex. 17 Arteriographic demonstration of arterial narrowing in patients with acute head injury has recently been reported. 2,7,9,12,~,26,27 The incidence of arterial narrowing ranges from 2% to 31%.…”

✓ Arteriography in 350 patients with a moderate to severe head injury, including repeated studies in 40 patients, revealed narrowing of one or more of the intracranial arteries in 65 patients (18.6%). Narrowing of the intracranial portion of the internal carotid artery and the first part of the anterior and middle cerebral arteries was found in 18 patients and was believed to be responsible for the clinical symptoms in some. Narrowing of the branches of the cerebral arteries at the site of the cerebral contusion was seen in 33 patients and diffuse narrowing of the intracranial arteries in 12. In two additional patients with gunshot wounds of the brain, there was narrowing of the cerebral artery adjoining a torn vessel. The evidence suggests that vascular spasm is responsible for the narrowing in some patients, while contusion and hemorrhage in the arterial wall is the cause in others. Whatever the mechanism, the occurrence and significance of cerebral arterial narrowing in association with acute head injury needs to be emphasized.

“…, Nagai et al 1974. The importance of blood in the cerebrospinal fluid of the basal cisterns in triggering off cerebral vasospasm has been already stressed by many investigators (Echlin 1965, Lin et al 1966, Chow et al 1968, Echlin 1971, Nagai et al 1974, Simeone et al 1975). In particular, serotonin, which is released within minutes from clots around the ruptured aneurysm, has been shown to exert a marked vasoconstrictive effect on the main cerebral arteries (Raynor et al, 1961, ^Jilkins et al 1966, Chow et al 1968, Allen et al 1974.…”

Severe vasospasm of the supraclinoidal portion of the internal carotid artery and the proximal part of the anterior and middle cerebral arteries was displayed by cerebral angiography in a 45 year old female patient who had developed progressive disturbance of consciousness and marked meningism with extremely bloody lumbar CSF within a few days after craniocerebral trauma. Aneurysm could be excluded angiographically and operatively. One and a half weeks after evacuation of a subdural haematoma and an intracerebral contusional bleeding, when the patient was discharged without any neurological deficit, control angiography showed that angiospasm had disappeared. The scanty literature on cerebral vasospasm after brain trauma is reviewed. The role of traumatic angiospasm in prognosis and the necessity for broad indications for cerebral angiography in cases with brain contusion is emphasized.
