目的探讨出血性脑梗塞（ＨＣＩ）的发病率、发病时间、易发于何种脑梗塞、继发性出血后的临床和脑ＣＴ表现。方法对２４例经脑ＣＴ检查证实的ＨＣＩ进行了回顾性分析。结果ＨＣＩ占我科同期脑梗塞的３．４％，占大面积梗塞的１１．８％，心源性脑栓塞出血者占同期脑栓塞的４７％，９１．６％的出血发生于脑梗塞后的２周内，７９．２％的病人临床症状加重，脑ＣＴ发现在原有梗塞灶内出现均匀的点状、斑片状出血（７５％）或单一血肿（２５％），９５．８％周围有不同程度的水肿。结论ＨＣＩ见于大面积脑梗塞，尤其是心源性者，出血多发生于脑梗塞后的２周内，可使临床症状加重，脑ＣＴ检查是确诊最常用和可靠的检查手段。
Objective To investigate the incidence of hemorrhagic cerebral infarction (HCI), the onset time, what kind of cerebral infarction is prone to occur, and the clinical manifestations after secondary hemorrhage. Methods A retrospective analysis of 24 HCI confirmed by brain CT examination was performed. Results HCI accounted for 3.4% of our department of cerebral infarction in the same period, accounting for 11.8% of the large infarction, cardiogenic cerebral embolism accounted for 47% of cerebral infarction over the same period, 91.6% of bleeding occurred after cerebral infarction In 79.2% of the patients within 2 weeks, the clinical symptoms were aggravated. Brain CT showed uniform punctate and patchy hemorrhage (75%) or single hematoma (25%) and 95.8% around the original infarct Have different degrees of edema. Conclusion HCI is found in large areas of cerebral infarction, especially those with cardiogenic origin. Bleeding occurs more than 2 weeks after cerebral infarction, which can aggravate clinical symptoms. Brain CT is the most commonly used and reliable method of diagnosis.
