Abstract:

Objective To compare the incidence, amounts and distribution of cerebral microbleeds (CMBs) in cerebral hemorrhage patients and cerebral infarction patients. Methods Stroke patients with complete data from Department of Neurology of People Hospital of Beijing Daxing District from August 2017 to December 2018 were consecutively enrolled in this study. All subjects were divided into cerebral hemorrhage and cerebral infarction groups. The image data of MRI SWI of all the patients within two weeks of onset were collected, to analyze the incidence, amounts and distribution of CMBs of the two groups. Results A total of 234 patients were selected, including 79 cases of cerebral hemorrhage and 155 cases of cerebral infarction. 65 (82.3%) cerebral hemorrhage patients had CMBs, and 41/65 (51.9%) patients had the amount of CMBs >5; 73 (47.1%) cerebral infarction patients had CMBs, 21/73 (13.6%) patients had the amount of CMBs >5. and the difference between the two groups was statistically significant (P <0.001). In cerebral hemorrhage group, CMBs involved both lobes and deep brain tissue in 40 patients (50.6%); in cerebral infarction group, CMBs involved both lobes and deep brain tissue in 25 cases (16.1%), and the difference between the two groups was statistically significant (P <0.001). Conclusions The amount of CMBs >5 were more common in cerebral hemorrhage patients than in cerebral infarction patients. CMBs involving both cerebral lobe and deep brain tissue were also more common in cerebral hemorrhage patients than in cerebral infarction patients.

摘要：

目的 探讨ICH和脑梗死患者合并脑微出血（cerebral microbleeds，CMBs）数量分级及部位分布差异。 方法 连续选取2017年8月-2018年12月在北京市大兴区人民医院神经内科病房住院且资料完整的 卒中患者，分为ICH和脑梗死两组。收集患者发病2周内头颅MRI磁敏感加权成像影像，统计ICH与脑梗 死患者中CMBs数量分级及部位分布特点。 结果 共入组患者234例，其中ICH组79例，脑梗死组155例。ICH组合并CMBs 65例（82.3%），其中 CMBs＞5个的患者41例（51.9%）；脑梗死组合并CMBs 73例（47.1%），其中CMBs＞5个的患者21例 （13.6%），两组差异有统计学意义（P＜0.001）。ICH组中，CMBs同时累及脑叶和深部脑组织的患者40例 （50.6%）；脑梗死组中，CMBs同时累及脑叶和深部脑组织的患者25例（16.1%），两组差异有统计学意 义（P＜0.001）。 结论 CMBs病灶＞5个多见于ICH患者；CMBs同时累及脑叶及深部脑组织多见于ICH患者。
