Bilateral internal carotid artery thrombosis. Prognosis and risk factors.

Fourteen patients with bilateral internal carotid artery thrombosis were analysed with respect to long-term prognosis and the prevalence of risk factors of cerebrovascular disease. The patients comprised seven per cent of all patients with internal carotid thrombosis treated in 1966-73 at the Department of Neurology, University of Helsinki. During the follow-up period of 3 to 86 months (median 50 months) five patients died, three during the first, and two during the second year of follow-up. Of the surviving patients: two needed institutionalization; three were able to take care of themselves; and four who were virtually symptom-free, were able to work. The risk factors of cerebrovascular disease were analysed: 91 per cent were cigarette smokers; 70 per cent had serum triglycerides of 140 mg/100ml or higher; and 62 per cent had cholesterol values of 280 mg/100 ml or higher. Fasting glucose values higher than 95 mg/100 ml, and ECG abnormalities were encountered in every third, and obesity and hypertension in every fourth patient. Cigarette smoking and high triglycerides were more prevalent than in the general population. No association between the number of risk factors in the individual patients and the prognosis could be found.

'Iatrogenic' brain stem infarction. A complication of x-ray examination of the cervical spine and following posterior tamponation of the nose.

Two patients sustained an ischemic brain stem infarction during medical examination and treatment. The first patient lost consciousness and the spontaneous respiration ceased during X-ray examination of the cervical spine when the neck was hyperextended. After some minutes he regained conciousness but was found to be tetraplegic, and the patient deceased 4 months later. The angiogram revealed thrombosis of the basilar artery. The other patient had profuse nosebleed and was treated with posterior tamponation during which she sat for about 10 min with the neck hyperextended. Some hours after this procedure symptoms and signs of lateral caudal brain stem infarction emerged.

The transient global amnesia syndrome. An analysis of 35 cases.

On basis of 35 patients who have suffered from transient global amnesia the pathophysiological mechanisms of this syndrome are discussed. Our impression is that the primary cause of this syndrome is a transient ischemia of the hippocampus, an opinion common with most earlier authors. The possibility of a unilateral hippocampal disturbance resulting in transient global amnesia is discussed. We are inclined to regard the local hippocampal ischemia as arising from insufficiency of the anterior chorioidal artery and thus as a sequel of internal carotid insufficiency, which has earlier been proved to result from various rotatory, flexion, and extension movements of the neck.

Chronic subdural hematoma in adults. Influence of patient's age on symptoms, signs, and thickness of hematoma.

The relationship of age to clinical and pathological findings was analyzed in 109 adult patients operated on because of chronic subdural hematoma. A well-formed membrane on the inner and outer surface of the hematoma was used as the criterion for chronicity of the hematoma. Younger patients had more evidence of increased intracranial pressure; older patients had more evidence of mental deterioration and pyramidal tract lesions. The interval from trauma to operation was shorter in the young patients. The thickness of the hematoma as measured from angiograms increased with the age of the patient. The cause of this difference is discussed.

Radiation myelopathy of cervical spinal cord simulating intramedullary neoplasm.

Radiation myelopathy is a well-known complication of irradiation therapy of neoplasms in the vicinity of the spinal cord. Most earlier authors have stressed the association of a normal myelogram and normal CSF protein level with this condition. One case of radiation myelopathy with a myelogram simulating intramedullary neoplasm and with extremely high CSF protein concentration is presented. Six months after myelography necropsy revealed severe atrophy of the previously thickened lower cervical spinal cord. The pathogenetic mechanisms are discussed.
