摘要
目的探讨后循环梗死患者MR／所示的病变分布与cT血管造影（computerizedtomographyangiography，CTA）表现之间的联系。方法纳入急性后循环梗死患者，依据MRI检查结果将梗死灶部位分为近段梗死、中段梗死和远段梗死。所有患者均行头颈部CTA检查。分析后循环梗死灶分布与椎基底动脉系统病变部位之间的联系。结果共纳入急性后循环梗死患者203例，主要临床症状和体征包括单侧肢体无力（77例，37．93％）、头晕（129例，63．55％）、构音障碍（31例，15．27％）、恶心和呕吐（61例，30．05％）、头痛（79例，38．92％）、步态异常（50例，24．63％）、眼球震颤（34例，16．75％）和共济失调（21例，10．34％）。近段梗死35例（17．24％）：延髓梗死28例（13．79％），小脑后下部梗死7例（3．45％）；中段梗死95例（46．79％）：脑桥梗死80例（39．4％），小脑前下梗死15例（7．39％）；远段梗死73例（35．96％）：中脑梗死6例（2．96％），小脑上梗死16例（7．88％），丘脑梗死34例（16．75％），枕叶梗死10例（4．93％），颞叶梗死7例（3．44％）。椎动脉颅外段病变以远段梗死组最多见，达53．42％，显著性高于近段梗死组的22．86％（P=0．003）和中段梗死组的33．68％（P=0．010）；椎动脉颅内段病变以近段梗死组最多见，达57．14％，其次为中段梗死（41．05％），均显著性高于远段梗死组的15．07％（P均=0．000）；基底动脉病变以中段梗死组最多见，达20．00％，显著性高于远段梗死组的4．11％（P=0．002）；大脑后动脉病变以远段梗死组最多见，达27．40％，显著性高于近段梗死组的5．71％（P=0．009）和中段梗死组的5．26％（P=0．000）。结论后循环梗死患者MRI所示的病变分布与椎基底动脉系统CTA显示的血管病变范围有着一定的联系。在近、中段梗死时，存在�
Objective To investigate the correlation between the distribution of lesions on MRI and the fnadings of computerized tomography angiography （CTA） in patients with posterior circulation infarction. Methods Patients with acute posterior circulation infarction were enrolled in the study. The sites of the infarcts were divided into proximal, middle and distal infarctions according to the results of MRI. All the patients received head and neck CTA. The correlation between the distrbution of posterior circulation infarcts and the sites of vertebrobasilar system lesions was analyzed. Results A total of 203 patients with acute posterior circulation infarction were enrolled. Their primary clinical symptoms and signs were unilateral limb weakness （n = 77, 37. 93%）, dizziness （n = 129, 63.55%）, dysarthrla （n = 31, 15.27%）, nausea and vomiting （n= 61, 30. 05%）, headache （n = 79, 38.92%）, gait abnormal （n= 50, 24. 63%）, nystagmus （n= 34, 16.75%）, and ataxia （n=21, 10.34%）. Proximal infarction （n= 35, 17.24%）：medullary infarction （n =28, 13.79%）, posterior inferior cerebellar artery infarction （n =7, 3.45%）; middle infarction （n =95, 46. 79% ）： pontine infarction （n = 80, 39.4% ）, anterior inferior cerebellar infarction （n = 15, 7.39%）; distal infarction （n= 73, 35.96%）： middle cerebral infarction （n= 6, 2.96%）, superior cerebellar infarction （n = 16, 7. 88% ）, thalamic infarction （n = 34, （16. 75% ）, occipital lobe infarction （n = 10, 4. 93%）, temporal lobe infarction （n= 7, 3.44%）. Extracranial vertebral artery lesions were most common in the distal infarction group. It reached 53.42%, and was significantly higher than 22.86% in the proximal infarction group （P =0. 003） and 33.68% in the middle infarction group （P =0. 010）. Intracranial vertebral artery lesions were most common in the proximal infarction group. It reached 57. 14%, and then followed by the middle infarction （41.05%）. They were all significantly higher than
