Head injury as a cause of internal carotid thrombosis.
نویسنده
چکیده
Thrombosis of the internal carotid artery with neurological signs may develop after direct violence to the wall of the artery in the neck. This has been known at least as far back as the last century and calls for little comment. A description of two such cases was published in 1936 by Caldwell, who warns against the error of attributing to concomitant head injury the symptoms and signs which develop as a result of traumatic thrombosis of the internal carotid artery in the neck. Ramsay Hunt first called attention to the occurrence of spontaneous thrombosis of the internal carotid artery in 1914. He and most successive authors conclude that arteriosclerosis is the most important aetiological factor. In this communication evidence is produced and the mechanism suggested whereby, in some cases of internal carotid thrombosis, a major or minor head injury may be instrumental in precipitating the thrombotic process. The clinical evidence of such a thrombosis may be immediate or delayed and in the latter event may present, some time after the injury, as a case of "spontaneous " thrombosis. Of the other known aetiological factors, thromboangiitis obliterans has been discussed by Davis and Perret (1947) and Cloake (1951). Thrombosis occurring after rupture of an intracranial aneurysm has been recorded. Only two cases are established in the literature in which a thrombotic process resulted from a head injury. One of these cases was described by the late Sir Hugh Cairns (1942) and he quoted another case under the care of Lohr. It is of interest that in these cases thrombosis occurred ,in the intracranial segment of the artery. The present series consists of six such cases; in five, a major head injury, and in one, minor trauma to the skull, are held responsible for the development of thrombosis of the intracranial segments of the artery.
