Traumatic occlusion of both internal carotid arteries

Dissection of the anterior and middle cerebral artery with fatal ischemia following kicks to the head

A 19-year-old male received kicks to his head in the course of a fight with other young people. On admission to hospital he became drowsy and developed a hemiparesis and a facial paralysis on the right. After 3-4 days of continuous improvement the patient suddenly fell unconscious again and died on the seventh day after the trauma due to an increase of the intracranial pressure. Neuropathologic examination revealed an extensive dissection of the wall of the left anterior and middle cerebral artery. The age of the recurring infarction in the dependent areas of blood supply corresponded to the biphasic clinical course.

The causes of stroke in the young

In a group of 75 patients under the age of 45 years with stroke, ischaemic cerebral infarction was diagnosed in 60 patients and primary intracerebral haemorrhage in 15. Trauma was found to be the commonest identifiable predisposing factor to cerebral infarction, being present in 13 cases (22%). Migraine was the second most commonly identified predisposing factor while atheroma and hypertension were infrequent. Such a high frequency of preceding trauma has not previously been described, perhaps because it is not generally appreciated that the delay between the traumatic event and subsequent stroke may be considerable. The diagnostic management of young stroke patients is considered with particular reference to the indications for specialized cardiac and neuroradiological investigations.
