脑血管造影未发现血管闭塞的急性脑梗死患者梗死区域与预后关系的研究

Study of relationship between infarction area and prognosis in acute cerebral infarction patients without vessel occlusion in brain angiography

目的研究脑血管造影未发现血管闭塞的急性脑梗死(ACI)患者的梗死区域与预后的关系。方法 49例发病<6h脑血管造影未发现血管闭塞的ACI患者,在发病<3d进行头颅CT或MRI检查,发病3个月后进行改良Ranking量表(mRS)评分,mRS评分≤2分为预后好。结果头颅MRI检查示,前循环梗死28例、后循环梗死21例。发病3个月后,前循环梗死组患者预后好的为20例(71.4%);而后循环梗死组为9例(42.8%);两组间差异有统计学意义(P<0.05)。结论脑血管造影未发现血管闭塞的ACI患者中,前循环梗死患者的预后大部分较好,而且预后好的比率明显高于后循环梗死患者。

Objective To study the relationship between infarction area and the prognosis in acute cerebral infarction （ACI） patients without vessel occlusion in brain angiogtaphy. Methods Forty-nine ACI patients without vessel occlusion by brain angiography within 6 d after onset were examined by cranial CT or MRI in 3 d after onset. The modeled Ranking scale （mRS） score was investigated at 3 months after onset,and the mRS score ≤2 showed good prognosis. Results The cranial MRI showed 28 patients with anterior circulation infarction and 21 patients with posterior circulation infarction. At 3 months after onset,20 patients （71. 4% ） of anterior circulation infarction group had good prognosis,while 9 patients （42. 8% ） of posterior circulation infarction group had good prognosis. The difference was statistically significant between the two groups （P 0. 05） . Conclusions Among ACI patients without vessel occlusion in brain angiogtaphy,most of those with anterior circulation infarction may have good prognosis,and the rate of which is significantly higher than that of posterior circulation infarction group.
