目的评价双源CT血管造影对脑梗死(CI)患者动脉粥样硬化斑块的诊断价值。方法选取2016年12月—2017年3月青海省心脑血管病专科医院收治的CI患者120例,均行双源CT血管造影检查,计算双源CT血管造影对CI患者动脉粥样硬化斑块检出率,观察椎动脉、颈内动脉颅外段、颈总动脉中部、颈动脉分叉处及颈总动脉起始处动脉粥样硬化斑块性质及分布情况。结果 120例CI患者中共检出动脉粥样硬化斑块84例(117处),检出率为70.0%,包括钙化斑块45例(53.6%),混合型斑块29例(34.5%),软斑10例(11.9%)。117处动脉粥样硬化斑块中,颈动脉斑块107处(91.5%),椎动脉斑块10处(8.5%);107处颈动脉粥样硬化斑块中颈动脉分叉处50处(42.7%)、颈内动脉颅外段28处(23.9%)、颈总动脉中部16处(13.7%)、颈总动脉起始处13处(11.1%)。结论双源CT血管造影对CI患者动脉粥样斑块的检出率较高,并可准确观察斑块位置。
Objective To evaluate the value of dual-source CT angiography in the diagnosis of atherosclerotic plaque in patients with cerebral infarction (CI). Methods 120 cases of CI patients admitted from December 2016 to March 2017 in Cardiovascular and Cerebrovascular Diseases Hospital of Qinghai Province were enrolled in this study. All the patients underwent double-source CT angiography to evaluate the effect of dual-source CT angiography on atherosclerotic plaques Detection rate, observe the vertebral artery, internal carotid artery extracranial, common carotid artery, carotid bifurcation and common carotid artery atherosclerosis at the beginning of the nature and distribution. Results A total of 84 atherosclerotic lesions were detected in 120 CI patients, with a detection rate of 70.0%, including 45 calcified plaques (53.6%), 29 mixed plaques (34.5%), Soft spot in 10 cases (11.9%). Among the 117 atherosclerotic plaques, there were 107 carotid plaques (91.5%) and 10 vertebral artery plaques (8.5%). Carotid artery bifurcation at 107 carotid atherosclerotic plaques 42.7%), 28 (23.9%) of the extracranial carotid artery, 16 (13.7%) of the common carotid artery and 13 (11.1%) of the common carotid artery. Conclusion Dual-source CT angiography has a higher detection rate of atherosclerotic plaques in CI patients and can accurately detect plaque location.
