急性大脑中动脉主干闭塞的超早期OCSP分型

目的：探讨牛津郡社区卒中项目（OCSP）分型在发病6小时内判断急性大脑中动脉M1段主干闭塞的可信度.方法：回顾性分析49例经过急诊头颅MRI和MRA证实为大脑中动脉M1段主干闭塞患者在发病6小时内和7天时OCSP分型情况.结果：发病后6小时内TACI 5例（10.20%）,PACI36例（73.47%）,LACI8例（16.32%）,POCI0例.7天时TACI 13例（26.53%）,PACI 34例（69.39%）,LACI 2例（4.08%） POCI0例.结论：急性血栓性（MACO）后6小时内和7天时均以PACI为主,且进展性卒中的发生率高,因此OCSP分型的临床价值有限,不能替代超早期的血管层面评价.

Exploring of ultra--early OCSP classification in MCAO stroke

Objective：To explore the credibility of Oxfordshire Community Stroke Project （OCSP） classification to evaluate the middle cerebral artery M1 segment oeclusion stroke patients with onset time less than 6 hours. Methods：The OCSP types of 49 cases with of acute MCA M1 segment occlusion stroke were retrospectively analyzed who exanimated by MRI and MRA with onset within 6 hours and On the 7^th day. Results：There were TACI 5 cases （10.20%）,PACI 36 eases（73.47%）,LACI 8 cases（16.32%）,and POC1 0 case with onset within 6 hours;TACI 13 cases （26.53%）, PACI 34 cases （69.39 % ）, LACI 2 cases （4.08%）and POCI0 case On the 7^th day. Conelusion：PACI was the main type among all the acute thrombosis MCAO within 6 hours and On the 7^th day, because thrombotic MACO had a higher ineidence of progression,the OCSP classification is not a substitute for the method of ultra--early evaluation of the blood vessels with limited clinical value.
