摘要
目的通过比较复发性脑梗死与首发性脑梗死患者CT血管成像(CTA)的特点,探讨复发性脑梗死患者可能的影响因素。方法回顾分析140例复发性脑梗死患者和235例首发性脑梗死患者头颈部CTA检查结果,比较两组患者头颈部血管病变的特点。结果复发性脑梗死患者头颈部动脉狭窄发生率明显高于首发性脑梗死患者(90.0%比64.7%;P<0.01),复发性脑梗死患者头颈部动脉中、重度狭窄发生率高于首发性脑梗死患者(分别为34.9%和45.2%比19.7%和15.8%;P<0.01),复发性脑梗死患者头颈部动脉斑块发生率明显高于首发性脑梗死患者(91.4%比66.4%;P<0.01),复发性脑梗死患者头颈部动脉软斑、溃疡斑发生率明显高于首发性脑梗死患者(分别为36.3%和48.0%比22.7%和37.3%;P<0.05)。结论复发性脑梗死与头颈部动脉狭窄及狭窄程度和不稳定性斑块有关,动脉狭窄的程度和斑块性质可能是引起复发性脑梗死的原因之一。
Aim By comparing characteristics in patients with recurrent cerebral infarction and first cerebral infarction with computed tomography angiography（ CTA）,to explore possible factors in patients with recurrent cerebral infarction. Methods We retrospectively analysed the test results of 140 cases of recurrent cerebral infarction patients and 235 cases of patients with head and neck CTA,and compared the characteristics of the two groups of patients with head and neck vascular lesions. Results Head and neck artery stenosis rate in patients with recurrent cerebral infarction was higher than that in patients with first cerebral infarction（ 90. 0% vs. 64. 7%; P〈0. 01）. Head and neck artery moderate stenosis and severe stenosis proportions in patients with recurrent cerebral infarction were higher than those in patients with first cerebral infarction（ 34. 9% and 45. 2% vs. 19. 7% and 15. 8%; P〈0. 01）. The incidence of head and neck artery plaque in patients with recurrent cerebral infarction was higher than that in patients with first cerebral infarction（ 91.4% vs. 66.4%,P〈0.01）. The proportion of soft plaque and ulcer plaque in patients with recurrent cerebral infarction were significantly higher than those in patients with first cerebral infarction（ 36. 3% and 48. 0% vs. 22. 7% and37. 3%; P〈0. 05）. Conclusions Recurrent cerebral infarction is related to head and neck artery stenosis,the degree of stenosis and unstable plaque,the degree of stenosis and plaque may be one cause of recurrent cerebral infarction.
