Abstract/OtherAbstract:
|
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. |
