摘要 目的探讨颈内动脉闭塞后临床症状、影像表现与侧支循环的关系。方法48例颈内动脉闭塞患者,分析临床表现、症状转归、MR I、TCD、MRA及DSA表现。结果48例患者39例以TIA的形式发病,28例最终发展成重偏瘫,32例伴发头痛。25例MRA上出现巨大病灶,交界区多发腔隙性梗死10例,单一腔隙性梗死6例,介于两者之间7例,合并脑萎缩12例。重症患者MR I表现病灶大,多合并其他血管病变,侧支循环不完全,患侧大脑中动脉灌注明显不足;轻症患者MR I表现病灶小,侧支循环完全开放,患侧大脑中动脉血流受损不明显。结论颈内动脉闭塞后临床症状、症状转归、表现与侧支循环建立的好坏有密切关系。血管损害单一,侧支循环好的患者病灶小,症状轻;血管损害广泛,侧支循环差的患者病灶大,症状重。
