Abstract:
Objective To study the value of 256 spiral CTA and DSA in diagnosis of carotid artery stenosis (CAS) and cerebral collateral circulation in acute ischemic stroke (AIS) patients.Methods The imaging data of 256 spiral CTA and DSA in 30 AIS patients were retrospectively analyzed.The sensitivity,specificity and consistency of 256 spiral CTA and DSA in diagnosis of CAS and cerebral collateral circulation were compared.Results The consistency rate of 256 spiral CTA and DSA was 82.8％ in diagnosis of CAS,especially in diagnosis of severe stenosis (κ=0.75).Cerebral collateral circulation was detected in 18 patients by 256 spiral CTA and in 19 patients by DSA with a consistency of 90 ％.Cerebral collateral circulation was detected in 40 by CTA and in 43 by DSA out of the 330 collateral arteries with a high consistency (κ=0.925,0.894).Conclusion The consistency of 256 spiral CTA and DSA is very high in diagnosis of CAS and cerebral collateral circulation in AIS patients.
