摘要 目的：结合CTA检查结果评估高血压和非高血压患者颅内外斑块特征，并分析其与高血压的相关性。方法：随机收集我院2019年5月-2020年5月行头颈部CTA检查的高血压患者60例（其中3级、2级、1级高血压患者分别为20例），择取同期非高血压患者60例，对所有患者CTA检查结果进行分析，对比两组患者的颅内外斑块特征。结果：存在斑块的概率上，高血压组的检出率显著高于非高血压组，且在高血压组中斑块数量与高血压等级呈一定程度正相关；此外，不同性质的斑块在不同高血压等级中分布不同。结论：颅内外斑块的发生与高血压有显著相关性，CTA是一项可以用于血管斑块特征分析的良好技术，可以为临床预测脑卒中风险提供有益思考。

Abstract: Objective: Combine the results of CTA to evaluate the characteristics of intracranial and extracranial plaques in patients with hypertension and non-hypertension, and analyze the correlation between plaques and hypertension. Methods: The 60 patients with hypertension who underwent head and neck CTA examinations in our hospital from May 2019 to May 2020 (including 20 patients with grade 3, grade 2, and grade 1 hypertension respectively) were collected, then we selected 60 patients with non-hypertension during the same period, at last, we analyzed the CTA results of all patients and compared the characteristics of intracranial and extracranial plaques between two groups. Results: In terms of the probability of plaque, the detection rate of hypertension group was significantly higher than that of non-hypertension group, and in the hypertension group, the number of plaques was positively correlated with the level of hypertension; In addition, plaques of different nature are distributed differently in different hypertension levels. Conclusion: The occurrence of intracranial and extracranial plaques is significantly related to hypertension; CTA is an excellent technology that can be used to analyze the characteristics of vascular plaques and can provide the useful thinking for clinical prediction of stroke risk.
