摘　　要：目的研究动脉粥样硬化所致单侧颈内动脉闭塞卒中类型。方法2006—10～2008—10收治的急性前循环脑梗死患者，行颈动脉超声、经颅多普勒超声（TCD）和磁共振血管成像（MRA），部分行数字减影全脑血管造影（DSA）检查，发现48例单侧颈内动脉闭塞患者为动脉粥样硬化所致，颈内动脉颈段闭塞28例，脑段闭塞20例。根据MRI分析单侧颈内动脉闭塞卒中类型。结果显著皮质下梗死20例（41．7％），边缘带梗死13例（27．1％），区域梗死8例（16．7％），弥散小梗死灶7例（14．5％）。结论动脉粥样硬化所致单侧颈内动脉闭塞卒中类型多为显著皮质下梗死和边缘带梗死。颈内动脉颈段闭塞组中边缘带梗死、区域梗死的发生率较颈内动脉脑段闭塞组高（42．8％vs 5．0％，28．6％vs 0），脑段闭塞组皮质下梗死的发生率较颈段闭塞组高（80．0％vs 14．3％）。Objective To study atherosclerotic occlusion of unilateral internal carotid artery＇s stroke types. Methods In the patients with acute ischemic cerebrovascular disease who were tilted by using TCD and MRA, partly by DSA,we discovered 48 patients with atherosclerotic occlusion of unilateral internal carotid artery and analyzed the stroke types according to their MRI. Results The number of predominant subcortex cerebral infaction was 20 cases （41.7%）, the number of boundary zone cerebral infaction was 13 cases（27.1%）, the number of sector cerebral infaction was 18 cases（ 16.7 % ）, and the number of diffusion sterigma was 7 cases（14.5%）. Conclusion Internal carotid artery occlusion（ICAO） stroke types most are the predominant subeortex and boundary zone cerebral infaction. The boundary zone and the sector cerebral infaction in the ICAO cervical segment groups are higher than the ICAO cerebral segment groups（42.8% vs 5.0%, 28.6%vs 0）. The predominance subcortex cerebral infaction in the ICAO cervical segment groups are higher than the ICAO cervical segment groups（80. 0%vs 14.3%）.
