USE OF COLOR POWER TRANSCRANIAL DOPPLER SONOGRAPHY TO MONITOR ANEURYSMAL COILING

We describe the use of a recently developed technique in the field of color Doppler sonography, called power Doppler or color Doppler energy , that produces better images of the intracranial arteries than those obtained by conventional color Doppler techniques. Color Doppler energ y makes it possible to identify aneurysms and their relationship to th e parent artery, thus allowing one to observe how much of an aneurysm remains patent and the condition of adjacent arteries during endovascu lar treatment. We describe the use of this technique during the insert ion of Guglielmi detachable coils into aneurysms and during subsequent follow-up examination.
