Application of 3D CT Angiography in Review of Intracranial Aneurysm Clipping

Objective:To evaluate the value of 3D CT angiography(3D-CTA) in review of intracranial aneurysm clipping.Methods:42 cases of intracranial aneurysm postoperative patients(45 aneurysms) of our department from August 2010 to January 2012,at the clip-ping of the aneurysm after 5-7 days,5-6 months,12 months to accept inspection of the three-dimensional CT angiography(3D-CTA) and digital subtraction angiography(DSA).DSA as the gold standard to evaluate the sensitivity and specificity of CTA in detected postopera-tive residual aneurysm,vascular occlusion and stenosis after clipping.Results:3D-CTA found four cases of residual aneurysm neck were consistent with vascular occlusion,28 cases of the parent artery patency,6 cases were blocking the parent artery does not develop,61 aneurysm clips can be clearly identified,with DSA consistent.3D-CTA evaluation of residual aneurysm neck and parent artery anasto-mosis patency of sensitivity and specificity were 100% consistency 1.0.Conclusion:3D-CTA examination is simple and the result is reli-able.With high clinical application valuation,3D-CTA is a good way for evaluating postoperative intracranial aneurysm that can be used as the primary method of intracranial aneurysm after long-term and multiple times follow-up.
