摘要
目的:评价B型超声波探查对外伤性颈动脉-海绵窦瘘的诊断价值。方法:回顾性分析4例4眼由外伤(头部车祸伤或跌倒头部着地伤)导致的颈动脉-海绵窦瘘患者的B型超声波扫查的声像特征。结果:超声探查发现4例患者球后脂肪垫内见B型超声声像图为眼上静脉为圆形或椭圆形回声区,内界为弱或无回声,边界清晰。眼眶压迫试验为阳性,如果压迫试验用的压力大时,无回声区将消失,眼眶肌肉回声有增粗。结论:B型超声波探查特征性声像图结合患者头部外伤,眼球充血,球结膜及结膜下血管怒张,呈深红色,眼底视网膜静脉血管扩张、眼球突出、复视等典型临床表现,对外伤性颈动脉-海绵窦瘘提供临床有用的诊断价值。
AIM：To evaluate the diagnostic value of B ultrasound scan in traumatic carotid-cavernous sinus fistula（TCCF） .·METHODS：The ultrasound characteristics of four TCCF cases（4 eyes） caused by road accident or falling down steps were analyzed retrospectively.·RESULTS：After examining the B-scan images of the orbital fat of four patients,we found that the echo areas of the superior ophthalmic vein were either round or elliptic. The boundaries of these areas were distinct and no echoes were detected within these boundaries. When the eyeballs were pressed with the probe,the diameter of the superior ophthalmic vein became smaller. Furthermore,a higher pressure led to the disappearance of no-echo areas . Additionally,the echo of extraocular muscle was enlarged.·CONCLUSION：Our data indicate that B-scan charac-teristics provide very useful information for diagnosis of TCCF combined with clinical description such as head trauma,eyeball congestion,bulbar conjunctival and subconjunctival vascular dilatation with scarlet color,retinal venous dilatation,exophthalmus,and diplopia.
