急性脑梗死OCSP分型与影像学分型的关系

目的探讨急性脑梗死牛津郡社区卒中项目(OCSP)分型与影像学分型的对应关系。方法回顾性分析236例急性脑梗死患者早期OCSP分型情况及其影像学特征。结果按OCSP分型:完全性前循环梗死(TAC I)28例(11.9%),部分性前循环梗死(PAC I)71例(30.1%),腔隙性梗死(LAC I)94例(39.8%),后循环梗死(POC I)43例(18.2%)。临床分型与影像学分型一致者共有171例,分型总准确率72.5%(171/236);各亚型分型准确率分别为TAC I 76%(25/33),PAC I 81%(34/42),LAC I71%(81/114),POC I 66%(31/47)。结论OCSP分型能正确预测梗阻部位和大小,与影像学检查结果有良好的对应关系。

Relationship between Oxfordshire community stroke project classification and imaging classification in acute cerebral infarction

Objective To investigate the relationship between Oxfordshire community stroke project(OCSP) classification and imaging classification in acute cerebral infarction. Methods Two hundred and thirty-six patients with acute cerebral infarction were retrospectively evaluated with OCSP classification and imaging characteristics. Results According to OCSP classification,of all the 236 patients with acute cerebral infarction,28(11.9%) experienced total anterior circulation infarction(TACI),71(30.1%) partial anterior circulation infarction(PACI),94(39.8%) lacunar infarction(LACI),and 43(18.2%) posterior circulation infarction(POCI).The consistency was found in 171 cases(72.5%) between the OCSP classification and imaging classification,with the accuracy of 76%(25/33) for TACI,81%(34/42) for PACI,71%(81/114) for LACI and 66%(31/47) for POCI. Conclusion OCSP classification can predict the location and size of cerebral infarction with a high accuracy,and is well consisted with the imaging findings.
