Hypodense regions demonstrated by CT within 6 hours of the onset of stroke may reflect irreversibly damaged tissue, and some have suggested that patients with such findings should be spared the risks of thrombolytic therapy since they are unable to benefit from it. We report here a patient with a low-density area demonstrated by CT less than 6 hours after onset of symptoms who improved dramatically after successful intra-arterial thrombolysis.
中风发作6小时内CT显示的低密度区域可能反映了不可逆损伤的组织，一些人认为有此类表现的患者应避免溶栓治疗的风险，因为他们无法从中获益。我们在此报告一名患者，其症状发作后不到6小时CT显示有低密度区，在成功进行动脉内溶栓后显著好转。
