经颅多普勒超声(transcranialDoppler,TCD)是目前常用的脑血流动力学检测方法,具有无创、便捷、价廉等特点。应用TCD监测脑血流储备能力可为颈动脉狭窄治疗的临床决策提供相关信息。颈动脉血管成形支架置入术(carotidangioplastyandstenting,CAS)时,TCD既可用来评估支架置入对血流动力学的影响,也可用来预测手术并发症(特别是术后过度灌注)。
Transcranial Doppler (TCD) is a non-invasive, convenient and inexpensive method for cerebral hemodynamic assessment widely used in clinical practice. Monitoring of cerebrovascular reserve capacity with TCD can provide relevant information for clinical decision making in the treatment of carotid stenosis. During carotid angioplasty and stenting, TCD can be used to evaluate effect of stenting on hemodynamies, and predict major complications, particularly postoperative hyperperfusion.
