摘　　要：目的探讨CT血管造影(CTA)对缺血性脑卒中(CIS)患者颈动脉粥样硬化斑块性质的诊断价值。方法选取2022年1月~2023年12月在本院收治的100例颈动脉粥样硬化斑块患者,根据CIS发生情况,分为CIS组(n=38)和非CIS组(n=62),比较两组颈动脉粥样硬化及斑块性质情况。结果经CTA检测,CIS组检测颈动脉血管314支,非CIS组检测颈动脉血管496支,CIS组关于颈动脉血管无狭窄及轻度狭窄率低于非CIS组,中度以上颈动脉血管狭窄率高于非CIS组(P<0.05)。CIS组314支颈动脉血管中,88支存在粥样硬化,硬化斑块占比为28.03%,斑块分布以颈内动脉颅内段处为主;非CIS组496支颈动脉血管中,62支存在粥样硬化,硬化斑块占比为12.50%,斑块分布以颈动脉分叉处为主(P<0.05)。CIS组颈动脉粥样硬化斑块以不规则形态、斑块溃疡以及环形状为主,非CIS组以规则形态、无斑块溃疡以及无环形状为主(P<0.05)。CIS组颈动脉粥样硬化斑块性质以软斑块和混合斑块为主,非CIS组以钙化斑块和纤维斑块为主(P<0.05)。结论CTA能够较好诊断CIS患者颈动脉狭窄情况、粥样硬化斑块分布以及斑块性质。Objective To explore the diagnostic value of CT angiography(CTA)in natures of carotid atherosclerotic plaques in patients with cerebral ischemic stroke(CIS).Methods A total of 100 patients with carotid atherosclerotic plaques in the hospital were enrolled between January 2022 and December 2023.According to presence or absence of CIS,they were divided into CIS group(n=38)and non-CIS group(n=62).The carotid atherosclerosis and plaque natures in the two groups were compared.Results CTA showed that there were 314 carotid vessels in CIS group and 496 carotid vessels in non-CIS group.The incidence of carotid non-stenosis and mild stenosis in CIS group was lower than that in non-CIS group,and incidence of moderate or above carotid stenosis was higher than that in non-CIS group(P<0.05).Among 314 carotid vessels in CIS group,there were 88 vessels(28.03%)with atherosclerosis,and plaques were mainly located in intracranial segment of internal carotid artery.Among 496 carotid vessels in non-CIS group,there were 62 vessels(12.50%)with atherosclerosis,and plaques were mainly located at bifurcation of carotid arteries(P<0.05).The atherosclerotic plaques were mainly characterized by irregular morphology,plaque ulceration and ring shape in CIS group,while which were mainly characterized by regular morphology,no plaque ulceration or ring shape in non-CIS group(P<0.05).The natures of carotid atherosclerotic plaques were mainly on soft and mixed plaques in CIS group,while which were mainly on calcified and fibrous plaques in non-CIS group(P<0.05).Conclusion CTA can better diagnose carotid stenosis,distribution and natures of atherosclerotic plaques in CIS patients.
