Application of 16-slice Spiral CT in the Diagnosis of Carotid Cavernous Fistula

Object To study the value 16-slice Spiral CT angiography in the diagnosis of carotid cavernous fistula. Material and methods 18 patients with carotid cavernous fistula were examined both with routine CT scanning and CTA,all performed Volume Rendering(VR),Maximum Intensity Projection(MIP)、Multiplanar(MPR). Results : Under Reconstruction,enlargement of cavernous sinus and development and enlargement of superior ophthalmic vein happened in 18 cases,development and enlargement of middle cerebral vein occurred in 8 cases at the arterial phase. A aneurysm was located at left middle cerebral artery in 18 cases. Conclusion 16-slice Spiral CT is of great value in the diagnosis of carotid cavernous fistula.
