【摘要】：目的采取超聲微泡(聲諾維)造影測定非動脈炎性前部缺血性視神經(jīng)病變(NAION)的患者視網(wǎng)膜中央動脈(CRA)的血液流動速率及血管走形。方法選取2016年1月至2016年10月之間于我院住并院確診為NAION的病患16例(17眼)和正常人13例(13眼),設計為患病組與對照組。分別對其進行超聲造影,造影劑采用聲諾維,采集兩組研究對象CRA的超聲造影的實時圖像,測定CRA血流速度,對結果進行統(tǒng)計分析。結果患病組CRA血流速度為(7.15±0.89)cm/s,對照組視CRA血流速度為(9.64±0.87)cm/s,其差別具有統(tǒng)計學意義(P0.01)。結論本實驗為首次采用超聲造影測量NAION患者CRA流速,直觀動態(tài)的觀察CRA的血流狀態(tài),并能評估血管走形,更優(yōu)于彩色超聲多普勒,為臨床評估CRA提供了一種新的技術手段。
[Abstract]:Objective to determine the blood flow rate and vascular deformity of central retinal artery (CRA) in patients with non-arteritis anterior ischemic optic neuropathy (NAION) by ultrasound microbubble angiography. Methods from January 2016 to October 2016, 16 patients (17 eyes) and 13 normal subjects (13 eyes) with NAION diagnosed in our hospital were selected as the disease group and the control group. Contrast-enhanced ultrasound was performed, and sonowei was used as contrast agent. The real-time images of CRA were collected, the blood flow velocity of CRA was measured, and the results were statistically analyzed. Results the CRA blood flow velocity in the diseased group was (7.15 鹵0.89) cm/s, and the CRA blood flow velocity in the control group was (9.64 鹵0.87) cm/s, which was significantly different from that in the control group (P 0.01). Conclusion this experiment is the first time to measure the velocity of CRA in patients with NAION, observe the blood flow state of CRA intuitively and dynamically, and evaluate the shape of blood vessels, which is better than color Doppler ultrasound, and provides a new technical method for clinical evaluation of CRA.
