心肌梗塞面积 infarct size
Background: When cerebral ischemia occurred, it is important for confining or deflating infarct volume and improving prognosis to remove obstacles from obstructive blood vessel and to recuperate hemoperfusion as early as possible.
研究背景:脑缺血发生后,尽早开通闭塞的血管,恢复血液灌流,是限制和缩小梗塞面积,改善预后的关键。
