title: Infarction and circulation in cerebrum. Effect of recanalization and/or collateral circulation on the lesion and prognosis.
abstract: Findings of computed tomography (CT) and angiography in supratentorial cerebral infarction associated with complete stroke were compared with regard to prognosis. It was found that the extent of low-density areas on CT was perfectly in accordance with the areas of occluded arteries on angiograms. However, the low-density areas on CT were always smaller than the areas involved angiographically when early recanalization and/or collateral circulation were carried out within 2 to 3 days of onset. It was also found that smaller low-density areas only had favorable effect. We concluded that the prognosis was better with early recanalization and/or collateral circulation, despite the general acceptance of its poor prognostic implication.
