Abstract:
Objective To observe the head and neck CTA application value in the diagnosis of ischemic cerebrovascular disease.Methods 430 patients with suspected diagnosis of ischemic cerebrovascular disease were adopted with head and neck CTA examination.The carotid artery stenosis degree,grade and plaque formation were observed,and the sensitivity and specificity of CTA in the diagnosis of ischemic cerebrovascular disease were calculated.Results After CTA examination,a tctal of 293 cases (68.14％) with carotid artery stenosis symptoms,among them 87 cases of mild stenosis,moderate stenosis in 169 cases,35 cases of severe stenosis and occlusion in 2 cases.430 plaques were detected in 430 patients,in extracranial arteries,81 soft plaques were identified,as well as 134 calcified plaque and 107 cases of mixed plaque,totally 322 cases;in intracranial arteries 312 cases of the soft plaque were identified,as well as 115 cases of calcified plaque and 97 cases of mixed plaque,totally 524 cases.The sensitivity of CTA in the diagnosis of ischemic cerebrovascular disease was 97.09％ and the specificity was 83.33％.Conclusion In the diagnosis of ischemic cerebrovascular disease,head and neck CTA examination for head and neck vascular stenosis and plaques has visual assessment,and high sensitivity,specificity.
