摘要
目的探讨CT血管造影术(CTA)与数字减影血管造影术(DSA)相比在诊断颈动脉狭窄疾病方面的可靠性。方法选健康成年犬解剖显露颈动脉后用缝合线部分缩窄颈动脉建立颈动脉狭窄动物模型,行CTA和DSA检查并进行比较分析。结果当颈动脉狭窄率<95%时CTA与DSA所测量的结果具有一致性,当狭窄率超过≥95%时CTA会夸大狭窄程度。结论CTA具有微创、安全、费用低、准确、高敏感度等优点,可用于颈动脉狭窄疾病的术前诊断、术后效果评价和随访以及流行病学调查研究。
Objective To explore the reliability of computer tomography angiography （CTA） and digital subtraction angiography （DSA） in the diagnosis of carotid artery stenosis. Methods The healthy adult dogs were exPosed and partly sutured carotid artery to establish carotid artery stenosis model and to examine by CTA and DSA. Results The detection results of CTA and DSA had concordance at carotid artery stenosis 〈 95%, but CTA exaggerated stenosis degree at carotid artery stenosis t≥95%. Conclusions CTA has advantages, such as mini-trauma, safety, low expense, accuracy and high sensitivity, which could be used in pre-operation diagnosis of carotid artery stenosis, post-operation evaluation, following up and epidemiological investigation.
