MSCTA在诊断外伤性颈动脉海绵窦瘘中的应用价值

Application of Multislice Spiral CT Angiography (CTA) in the Diagnosis of Traumatic Carotid Cavernous Fistula

目的:探讨64排螺旋CT血管造影(CTA)在诊断外伤性颈动脉海绵窦瘘中的应用价值。方法分析8例外伤性颈动脉海绵窦瘘病例。对受检者行颅脑CT平扫及CTA检查,采用容积再现(VR)、最大密度投影(MIP)、多平面重建(MPR)、曲面重建(CPR)技术处理图像。结果:8例均海绵窦扩大、动脉期眼上静脉显影并扩张。结论:64排螺旋CT血管造影对诊断外伤性颈内动脉海绵窦瘘有重要的应用价值。

Objective： To study the value of 64-slice Spiral CT angiography in the diagnosis of traumatic carotid cavernous fistula.Methods： 8 patients with traumatic carotid cavernous fistula were examined both with routine CT scanning and CTA,all performed Volume Rendering（VR）,Maximum Intensity Projection（MIP）、multi plane reconstruction （MPR）.Results： 8 cases were cavernous sinus to expand,Ophthalmic vein in arterial phase,and expansion.Conclusion： 64-slice Spiral CT is of great value in the diagnosis of traumatic carotid cavernous fistula.
