Analysis of vertebrobasilar atherosclerosis by using dual-source CT angiography in patients with transient ischemia attack / 中华老年医学杂志

ABSTRACT

Objective To investigate the diagnostic value of dual-source CT angiography (DSCTA) for vertebrobasilar atherosclerosis in patients with transient ischemia attack (TIA).Methods 80 TIA patients underwent DSCTA.Common data were collected.Vertebrobasilar plaques and stenosis degree were analyzed by using CT reconstruction.Results 152 plaques were found in 69 patients(86.2％,69/80),59 plaques(38.9％,59/152)in unilateral vertebral artery in 31 patients,83 plaques (54.6％,83/152) inbilateral vertebral artery in 28 cases,10 plaques (6.6％,10/152) in basilar artery in 10 patients,among which 51(33.6％,51/152)plaques were hard,69(45.3％,69/ 152)plaques were soft,32(21.1％,32/152)plaques were mixed.There were 31 cases (44.9％,31/ 69) with mild stenosis,27 cases (39.1％,27/69) with moderate stenosis,7 cases (10.1％,7/69) with severe stenosis,and 4 cases (5.8％,4/69) had vascular occlusion.Conclusions Vertebrobasilar atherosclerosis is a common cause of TIA.DSCTA can be used to analyze the vertebrobasilar plaques and stenosis degree.Soft plaques and severe stenosis promote TIA.
