摘要
目的 探讨无局灶体征脑于梗死的临床特征,提高临床医师对不典型脑干梗死的认识。方法 对23例无局灶体征的脑干梗死(A组)与26例椎基底动脉供血不足(V-BAI)(B组)患者的临床表现、CT、MRI、经颅多普勒(TCD)进行分析。结果 A组以持续症状为主,治疗效果较差,其TCD改变不如B组明显;A组所有患者脑干MRI上均可见到等或长T1W、长T2W梗死灶。结论 凡症状持续、疗效较差、TCD改变不明显,要高度怀疑脑干梗死;MRI是无局灶体征脑干梗死最可靠的检查方法。
Objective To explore the clinical characteristics of brainstem infarction without signs of localization. Methods 23 patients with brainstem infarction without signs of localization (group A)were compared with 26 i;ases of vertebrobasilar artery insufficiency( V-BAI)( group B)by clinical features, CT, MRI and transcranial Doppler (TCD). Results The patients in group A had persistent symptoms of V-BAI, unsatisfactory therapeutic results and no obvious changes at TCD,as compared with those in group B.The identical or long T1 W and T2W infarction fous could be found in the brainstems of all the patients in group A by MRI. Conclusion Brainstem infarction should Be highly suspected in the patients presenting persistent symptoms of V-BAI with unsatisfactory therapeutic results and no obvious changes at TCD. MRI examination is necessary for the patients with brainstem infarction.
