Abstract

Transcranial Doppler ultrasonography is the most commonly used method of cerebrovascular blood flow velocity measurement, but it is subject to certain technical and anatomic limitations. The Doppler velocity guidewire measures blood flow velocity within any vessel during cerebral angiography, overcoming these limitations. We report the first use of this guidewire in the measurement of blood flow velocity during balloon test occlusion, with results similar to simultaneously measured transcranial Doppler ultrasonography. Velocity measurement by Doppler guidewire could be useful in balloon test occlusion for vertebrobasilar circulation, where transcranial Doppler ultrasonography is limited, and provide anatomically specific blood flow velocity measurements in the diagnosis and treatment of stroke and other cerebrovascular diseases.

摘要

经颅多普勒超声是最常用的脑血管血流速度测量方法，但它受到一定的技术和解剖限制。多普勒速度导丝在脑血管造影期间测量任何血管内的血流速度，克服了这些限制。我们报告了该导丝首次用于在球囊闭塞试验期间测量血流速度，结果与同时测量的经颅多普勒超声相似。在经颅多普勒超声受限的椎基底动脉循环的球囊闭塞试验中，多普勒导丝的速度测量可能有用，并为中风和其他脑血管疾病的诊断和治疗提供解剖特异性的血流速度测量。
