首诊于眼科的颈动脉海绵窦瘘临床及影像学特征分析

The Clinical and Imaging Features of carotid artery cavernous sinus fistula by ophthalmologists

目的探讨颈动脉海绵窦瘘的临床特征及影像学检查在颈动脉海绵窦瘘诊断中的价值。方法回顾分析首诊于我院眼科的28例颈动脉海绵窦瘘的眼部特征及B超、彩色多普勒超声、CT、MRI检查。结果颈动脉海绵窦瘘临床表现眼红、眼球运动障碍、搏动性眼球突出等,B超显示眼上静脉不同程度扩张,部分可见搏动。彩色多普勒超声检查显示眼上静脉扩张动脉化并可探及搏动性动脉频谱。眼眶CT显示扩张的眼上静脉。MRI检查在T1WI和T2WI均显示扩张的眼上静脉,且均呈低信号。结论颈动脉海绵窦瘘因其临床眼部特征明显而首诊于眼科,需要引起眼科医生的高度重视。影像学检查有助于诊断,各种影像学检查各有其特点,互相结合多可作出正确诊断。

Objective To study the clinical features of the carotid artery cavernous sinus fistula(CCF)by ophthalmologists and the useful value of the imaging in the diagnosis.Methods To retrospective analysis the ocular signs and B-ultrasonic,the Color Doppler imaging(CDI),CT detection,and MRI of the 28 cases of CCF.Results B-ultrasonic could determine the enlarged superior ophthalmic vein(SOV)and most could detect the pulsation.;The CDI could determine dilated superior ophthalmic vein(SOV)with arterialized blood flow;CT revealed the enlarged superior ophthalmic vein(SOV);MRI showed the enlarged superior ophthalmic vein(SOV)and showed low signals on TIWI and T2WI.Conclusions The typical eye signs of CCF often be diagnosis by ophthalmologists,so the ophthalmologists should pay attention to it.Imaging is helpful for the diagnosis,each method of examination has its own advantages,combining of various methods can lead to an accurate diagnosis of CCF.
