摘　　要：目的　分析小脑前下动脉 (AICA)梗死的临床表现及 MR改变 ,并探讨 AICA梗死形成的原因。方法　对 2 2例 AICA梗死患者的临床表现、MRI及 MRA进行分析。结果　 AICA梗死的主要累及小脑中脚和 (或 )脑桥外下方 ,其症状体征以眩晕及共济失调为主 ,可合并多组颅神经受累 ,以 对颅神经受累最具特征性。MRA上单纯 AICA梗死单侧者 ,基底动脉 (BA)显示良好 ,双侧 AICA梗死及合并其它小脑梗死者 BA未显影或显示狭窄。结论　 AICA梗死的诊断主要依靠 MRI,MRA对判定病因及预后有重要意义。Objective To analyse the clinical features and MRI manifestations of the anterior inferior cerebellar artery(AICA) territory infarction,and to explore it’s pathogenesis cause. Methods 22 cases of AICA territory infarction were retrospectively studied by clinical features,MRI and MRA manifestations. Results The mid cerebellar peduncle and the inferior lateral pontine area were always involved in AICA infarction. The main clinical features of AICA territory infarction were vertigo and ataxia. There could be multiple cranial nerves involvement,of which,the typical one was the 8th cranial never involvement. MRA show normal basilar artery(BA) in simple unilateral AICA infarction,whereas in bilateral AICA infarction or complicated with the infarction of other parts of the cerebellum,MRA showed BA occlusion or stenosis. Conclusion The diagnosis of AICA infarction is mainly dependant on MRI. MRA bears great significance in assessing its causes and prognoses.
