目的:CTA对于评估颅内动脉狭窄程度和颅内支架随访是一种无创性检查。我们通过分析一组病例来评估CTA关于颅内血管支架成形术前后的动脉狭窄程度及支架随访的可行性。方法:颅内放置支架前后的8例患者接受CTA检查,一共有9个动脉狭窄并有临床症状。用CTA与传统血管造影对观察血管 Purpose: CTA is a noninvasive method for assessing the extent of intracranial arterial stenosis and follow-up of intracranial stents. We analyzed a group of patients to assess the CTA on the degree of arterial stenosis before and after intracranial stent and the feasibility of stent follow-up. METHODS: CTA was performed in 8 patients before and after intracranial stent placement, with a total of 9 arterial stenoses and clinical signs. CTA and conventional angiography on the observation of blood vessels
