Facial thermography in the diagnosis of cerebrovascular disease and in evaluation of carotid endarterectomy.
Some 60% of strokes are due to extracranial occlusive arterial lesions, most frequently at the bifurcation of the common carotid artery. Since these lesions are accessible to endarterectomy, their prestroke diagnosis is very important. Facial thermography quickly supplies reliqble information on the circulatory area in which these lesions occur, and this information can be atraumatically obtained in an out-patient setting. The success rate of facial thermography versus aortic arch angiography was 83% and 80%, respectively, in our case material, and this rate corresponds with data in the literature. In a series of 23 patients with facial thermograms and angiograms obtained before and after endarterectomy, facial thermography proved to be a useful diagnostic and prognostic aid in neurological out-patient guidance after carotid endarterectomy. By virtue of its rapidity and atraumatic character, because it can be carried out by technicians and because the findings are suitable for computer data processing, facial thermography would seem to be suitable for potential stroke screening of a high-risk asymptomatic population.
