目前无创性检查是估价颈动脉狭窄的可靠方法,本研究目的,(1)应用无创技术,眼肺体积描记法(简称OPPG)和Doppler眼试验(简称DOT)对疑有颈动脉狭窄者作颈内动脉血流减慢所致损害测定。(2)了解神经病变及其后遗症能否由有血液动力学意义的颈动脉狭窄所预测。
At present, noninvasive examination is a reliable method to evaluate carotid artery stenosis. The purpose of this study is: (1) Noninvasive techniques, ophthalmic lung plethysmography (OPPG) and Doppler eye test (DOT) Internal arterial blood flow slowed damage determination. (2) To understand whether neuropathy and its sequelae can be predicted by hemodynamically significant carotid stenosis.
