Utility of Intravascular Ultrasound in Neurointerventions
Utility of Intravascular Ultrasound in Neurointerventions
Intravascular ultrasound (IVUS) generates high-resolution cross-sectional images and sagittal reconstructions of the vessel wall and lumen. As a result, this imaging modality can provide accurate measurements of the degree of vessel stenosis, allow the detection of intraluminal thrombus, and analyze the plaque composition. The IVUS modality is widely used in interventional cardiology, and its use in neurointerventions has gradually increased. With case examples, the authors illustrate the utility of IVUS as an adjunct to conventional angiography for a wide range of intracranial and extracranial neurointerventions.
Intravascular ultrasound is widely used in interventional cardiology. It is routinely used to assess proper stent apposition after coronary stent placement and to determine the most appropriate treatment for indeterminate lesions on the basis of conventional coronary angiography. Recently, IVUS assessment of coronary atherosclerotic plaque progression was used as a surrogate primary end point in large statin trials. Few reports have been published regarding the use of IVUS in neuroendovascular interventions. In this review, we discuss IVUS technology and our clinical experience with this modality over a wide range of extra- and intracranial neurointerventions, and we also present illustrative cases.
