Abstract:
Objective To assess the value of CTA and DSA in neurovascular diseases.Methods 20 cases with suspected neurovascular disorders who received CTA and DSA examination between March 1999 and August 2000 were retrospectively collected.The sensitivity,specifility and accurate rate of CTA were analysed compared with DSA as gold standard.Results In 20 cases,neurovascular disorders were found in 17 on CTA.18 lesions were detected,including 6 aneurysms,9 arteriovenous malformations(AVM),2 carotid cavernous fistulae(CCFs)and 1 arterial stenosis.By contrast,19 lesions in 17 cases were detected by DSA,including 7 aneurysms,8 AVMs,2 arterial stenoses and 2 CCFs.The sensitivity,specificity and accuracy of CTA in the detection of neurovascular disorders were 90.6%,95.2% and 90.6% respectively.Conclusion 3D-CTA is a new modality with high sensitivity and specificity in the detection of neurovascular disorders.As it can be obtained simply,conveniently and safely with mild injury to the patient,CTA can be used in the diagnosis of neurovascular diseases,especially in the AVMs.
