OBJECTIVE: To evaluate the diagnostic accuracy of three-dimensional CT angiography in the surgical treatment of @entity438 . METHODS: Twenty-four @entity1 suspected of @entity438 underwent routine catheter four-vessel angiography, three dimensional CT angiography (3D-CTA), magnetic resonance angiography (MRA) or conventional digital subtraction angiography (DSA). RESULTS: A total of 28 @entity439 were detected by CT angiography in this study. Twenty-one @entity1 each had a single @entity439 , two @entity1 each had two @entity439 , and one had three @entity439 . The shapes of @entity439 revealed by 3D-CTA were round in 20 lesions, elliptical in 5, and 1 obulated in 3. Of the 24 lesions which were completely disclosed during surgery, the shapes correlated well with the 3D-CT angiograms. The mean diameter of the @entity439 was 5.9 mm in 3D-CTA images, with the smallest being 1.6 mm and the largest 13.7 mm. The size was very close to the actual size measured at surgery (P < 0.001), revealing that 3D-CT angiograms correlated well with surgical findings. Compared with images obtained by routine catheter four-vessel angiography, MRA and DSA, 3D-CTA images depicted the relationship of @entity439 to parent vessels and other branches more clearly. CONCLUSION: 3D-CTA enables surgeons to understand the 3D structure of @entity438 and is very useful in planning the surgical treatment of @entity438 .
