Abstract

When a physician is faced by a patient suffering from transient ischemic attacks, the diagnosis is almost invariably determined by the clinical history. It becomes necessary to eliminate certain other medical conditions including migraine, focal epilepsy and cardiac disorders. Once he is satisfied with the diagnosis of TIA, then he must consider whether to employ medical or surgical therapy or a combination of both. It must be recognized that TIAs are not benign events since more than 50 p. 100 of individuals who develop completed strokes will have antecedent TIAs. Identification of the pathogenetic mechanism becomes important in choosing the specific therapy. Where the origin of the attacks is clearly thromboembolic, secondary to atherosclerosis, surgical intervention may be appropriate if the lesion is readily accessible. However, consideration of surgery is also determined by the risk of post-operative stroke or death at the hands of less experienced surgeons. The risk of stroke in a patient who is having frequent TIAs may be reduced initially by utilizing anticoagulants for a limited period. Long-term medical therapy requires the use of anti-platelet agents which have been shown to have a more beneficial effect in preventin...Continue Reading
