目的 探讨出血性脑梗死 (HI)的临床与CT表现特点。方法 利用同期住院脑梗死患者 ,根据其临床症状变化并动态观察头颅CT表现 ,然后进行临床与CT分析。结果 HI发生占同期住院脑梗死患者的 4.3% ,且在病后 1～ 2周发生率最高 ,发生HI时部分患者病情再度加重 ,且以头痛频度最高 ,也有部分患者临床症状可无变化。头颅CT多表现为低密度影内可见散在斑点、斑片状或团块状高密度影。结论 掌握HI的临床特点 ,对脑梗死患者特别是大面积脑梗死患者 ,不论其临床症状有无加重 ,均须定期作头颅CT检查 ,以便及时发现本病 ,争取合理治疗。
Objective To investigate the clinical and CT features of hemorrhagic cerebral infarction (HI). Methods Patients in the same period of hospitalized cerebral infarction, according to their clinical symptoms and dynamic observation of head CT findings, and clinical and CT analysis. Results HI accounted for 4.3% of hospitalized patients with cerebral infarction in the same period, and the incidence was highest in 1 ~ 2 weeks after HI. Some patients experienced aggravated again with HI, and some patients had no clinical symptoms. Skull CT showed low-density intracranial scattered spots, patchy or massive high-density shadow. Conclusion To master the clinical features of HI, patients with cerebral infarction, especially large area cerebral infarction, regardless of whether the clinical symptoms aggravate, must be regularly skull CT examination in order to find the disease in time, for a reasonable treatment.
