Application of Thigh Cuffs Release Test in the Evaluation of Cerebral Autoregulation

doi:10.3969/j.issn.1673-5765.2019.03.009

Abstract

Abstract:

The thigh cuffs release test (TCRT) is a common method of evaluating dCA. The test method is as follows: in?ating the above-knee cuffs at first, subsequently de?ating the cuffs rapidly, which causes a sudden fall of arterial blood pressure (ABP)and cerebral blood flow velocity (CBFV), the changes of ABP and CBFV are recorded to evaluate the dCA. This method is cheap, simple and convenient, non-invasive and repeatable, because of these advantages, it is widely used in the evaluation of dCA in patients with acute ischemic stroke, severe head trauma and severe preeclampsia. This article reviewed the present status of application of TCRT in the evaluation of dCA .

Key words: Thigh cuffs release test; Cerebral autoregulation; Transcranial Doppler

摘要：

下肢袖带释放实验（thigh c uffs r elease t est，TCRT）是由Rune A aslid于1989年首先提出，在双侧大腿绑上袖带，先充气，后快速放气，使血液重新汇集于双侧大腿，造成动脉血压（arterial blood pressure，ABP）与脑血流速度（cerebral blood flow velocity，CBFV）急骤下降，同时记录ABP和 CBFV的变化，进而评估dCA，是评估dCA常用诱发方法之一。目前临床上TCRT多应用于急性缺血性卒中、头外伤、重度子痫等的dCA评估。该方法具有价廉、简便、无创、可重复等优势。本文就TCRT在dCA评估中的应用现状做一简要综述。
