Clinical analysis of 52 patients with cerebral hemorrhagic infarction

[Objective] To study the incidence,causes,clinical and radiological characteristics as well as the short-term prognosis in patients with cerebral hemorrhagic infarction(HI).[Methods] Clinical data were collected and analyzed retrospectively on 52 patients with HI admitted to our hospital between 2001 and 2005.[Results] The incidence of HI was 7.3%(52/713).The major causes of HI were cerebral embolism(78.8%),especially cardiogenic embolism(61.5%).The secondary bleeding most commonly occurred within two weeks after ischemic stroke,31(59.6%) within the first week,and 17(32.7%)the second.Patients with HI occurred within the first week presented poorer short-term prognosis than those occurred later than one week(P0.05).HI was categorized according to radiological characteristics: hematomic and nonhamotomic type.The short-term prognosis of the hematomic type was significantly worse than that of the nonhamotomic type(P0.05).The overall mortality was 15.4%.[Conclusion] The incidence of HI is not rare.It is worthy to emphasized that the radiological reexamination in patients with cerebral embolism or large infarction during 1～2 weeks after stroke will be helpful for the diagnosis and treatment of HI without delay.
