[摘要] 目的：研究大脑中动脉区进展性脑梗死在DWI梗死类型及相关MRA血管狭窄表现，探讨其发病机制。方法：MCA区进展性脑梗死112例为进展组，同期MCA区完全性梗死130例为完全组，研究两组患者缺血性卒中类型及相关血管狭窄情况。急性期DWI上梗死类型分为4种：区域梗死、皮质下梗死、边缘带梗死、弥散小梗死。结果：进展组中边缘带梗死发生率较完全组高(60.7% vs 13.1%；P<0.05)，以MCA狭窄为主(49.1% vs 20.8%；P<0.05)，且易出现多支血管狭窄；完全组中区域梗死发生率较进展组高(56.2% vs 8.9%；P<0.05)，以MCA闭塞(38.4% vs 8.9%；P<0.05)为主。结论：MCA区进展性脑梗死易发生于MCA狭窄及多支血管狭窄引起的边缘带梗死，脑灌注不足可能是其主要原因。

[Abstract] Objective: To investigate lesion patterns on DWI and stroke mechanism in acute progressive cerebral infarction in middle cerebral artery area, and its MRA angiostenosis performance. Methods: The MCA area progressive cerebral infarction patients 112 examples for the progress group, the MCA area complete cerebral infarction patients at the same time 130 examples were a complete group. Studies two group of patients lesion patterns and the correlation angiostenosis situation. On acute stage DWI the lesion patterns divides into 4 kinds: territor infarcts, subcortical infarcts, border-zone infarcts, and several disseminated small infarcts. Results: The incidence ratio of border-zone infarcts was greater in the progress group than in the complete group(60.7% vs 13.1%; P<0.05), by MCA severe stenosis primarily(49.1% vs 20.8%; P<0.05), and also easy to appear many angiostenosis; the incidence ratio of territor infarcts was greater in the complete group than in the progress group(56.2% vs 8.9%; P<0.05), by MCA occlusion primarily(38.4% vs 8.9%; P<0.05). Conclusion: Border zone infarcts are more seen inMCA severe stenosis and many angiostenosis in MCA area progressive cerebral infarction, the brain irrigation insufficient is possiblyits primary cause.
