Abstract

Incidence. Risk factors. Precipitating factors and clinical symptoms and signs were obsenied in 52 patients with borderzone infarction. The proportion of borderone infarction was 10% of all infarction. The site of borderzone infarction was subcortical borderzone in 23 cases, posterior borderzone in 20 cases and anterior borderzone in 17 cases. Borderzone infarction was localized in unilateral single borderzone in 45, unilateral multiple borderzone in 4 and bilateral borderzone in 3 cases. Risk factors of borderzone infarction were hypertension, smoking, hyperlipidemia, previous stroke history. Diabetes mellitus and cardiac disease. The frequency of hypertension was higher in borderzone infarction than in territorial infarction. Precipitating factors of borderzone infarction were dehydration due to sweating, diarrhea or vomiting and moderate or severe anemia. Neurologic findings in patients with borderzone infarction were hemiparesis, aphasia. Homonymous hemianopsia, rnental change and hemihypoesthesia. Aphasia was developed in 53.6% of all left hemispheric single borderzone infarction and the type of language disturbance was global. Sensory, motor, anomic or thanscortical motor aphasia. From the above results, it is postulated that the frequency of hypertension is higher and the frequency of cardiac disease is lower and that precipitating factors, can lead to hemodynarnic cerebral hypoperfusion, such as severe vomiting, sweating, diarrhea and anemia are more common in borderzone infarction than in territorial infarction.
