摘　　要：目的 :通过对位于眶上缘皮下的眼动脉终支 -滑车上动脉 (STCA)的彩色多普勒超声 (CDFI)检测 ,观测急性眼外伤眼部血流动力学改变。方法 :在正常对照组 2 0例和急性眼外伤患者 2 4例的眶上缘内侧 STCA出眶部位行 CDFI及脉冲多普勒超声检测。结果 :对照组 STCA出眶处彩色血流信号及多普勒频谱检出率为 10 0 % ,其频谱特征与眼动脉相似 ,为正向三峰型 :SP1 峰、 SP2 峰、 DP峰 ,SP1 >SP2 ;其血流速度 Vs为 32 .2～ 32 .4 cm/ s,与眼动脉相似。眼外伤患者 Vs、 Vd明显高于对照组及健侧眼 (P<0 .0 0 1) ,其双眼 Vs比值亦高于对照组 (P<0 .0 5 )。结论 :STCA的 CDFI检测是一种实时、准确、方便、价廉、无损伤性、易于掌握。Objective:To observe the hemodynamics in acute eye injury through detecting supratrochlear artery (STCA) which was the end branch of ophthalmic artery at supraorbital foramen.Methods:Twenty normal controls and 24 acute eye injury patients facial STCA were detected at the supraorbital foramen by color and pulsed Doppler ultrasound.Results:STCA could be displayed at supraorbital foramen.with 100%.there were similar frequency spectra between STCA and ophthalmic artery with three peaks,SP 1, SP 2,DP and SP 1>SP 2.Vs was 32 2～32 4cm/s, Vs and Vd in acute eye injury were higher than those in the control and the contralateral groups ( P <0 001).The Vs ratio of double eyes was higher than that in the control group also ( P <0 05).Conclusions:Color Doppler ultrasound is a new real-time, accurate noninvasive,convenient and cheep method for diagnosing the hemodynamics of acute eye injury through detecting STCA It is easy to master and common to use.
