Abstract
Objective To explore the time regularity of hemorrhagic transformation (HT) in cerebral infarction (CI) and the magnetic resonance imaging (MRI) classification.Methods A total of 93 cases of HT patients admitted to our hospital were analyzed retrospectively,including 35 cases of embolic cerebral infarction and 58 cases of thrombotic cerebral infarction.The time regularity of HT and the features of MRI images were analyzed.Results Most of HTs occurred during 1-3 d after the onset of embolic cerebral infarction and during 4-7 d after the onset of thrombotic cerebral infarction,so the onset of the former was significantly earlier than that of the latter (P ＜ 0.05).The proportion of HT only in the supratentorial region was 82.8％ and that only in the subtentorial region was 12.9％,while that in both supratentorial and subtentorial regions was 4.3％.In the form of HT hemorrhage,there were 49 cases of cerebral gyrus and linear hemorrhage (mainly in the lobes),39 cases of speckled and patch like bleeding (mainly in the lobes and basal ganglia),and five cases of hematoma (mainly in the lobes).The MRI classification for HT in cerebral infarction was proposed as:supratentorial non-hematoma type (type Ⅰ),subtentorial non-hematoma type (type Ⅱ),hematoma formation type (type Ⅲ) and mixed (supratentorial+subtentorial) non-hematoma type (type Ⅳ).Conclusion The onset time of HT in thrombotic cerebral infarction is earlier than that of embolic cerebral infarction.The standard for MRI classification proposed in this study is helpful for understanding the region of HT,the form of hemorrhage and the situation of hematoma,which is of certain guiding significance for clinical diagnosis and treatment.关键词
