Analysis of the clinical features and risk factors of hemorrhagic infarction

Objective:To investigate the nosogenesis,risk factors and clinical features of hemorrhagic infarction(HI).Methods: 108 patients with CT-documented or MRI-documented HI among 2496 cerebral infarction patients were collected and information about their clinical and image document was analyzed retrospectively.The cortical infarction,infarct size,neurologic impairment,blood glucose and blood pressure between HI and non-hemorrhagic infarction(NHI) were compared.Results:Hemorrhagic infarction incidence rate was 4.3%.Hemorrhage often appeared in two week of cerebral infarction,most of them were negative hematoma,and hematoma were few,but parenchymal hematoma type 2 were unfavorable prognosis.HI was related to cortical infarction,large areas of infarction,severe neurologic impairment,high blood pressure and high blood sugar.Conclusions:Only parenchymal hematoma type 2 independently causes clinical deterioration and impairs prognosis.The patients with cortical infarction,large areas of infarction,severe neurologic impairment,high blood pressure,or high blood sugar should be closely observed dynamically,attention to the possibility of hemorrhagic infarction,timely reviewing head CT/MRI and adjusting the treatment program.For the diagnosis of HI,MRI was better than CT.
