title: Proposed methodology and classification of Infarct in New Territory (INT) after endovascular stroke treatment.
abstract: While the overall complication rates for endovascular treatment for acute stroke has been extremely low in recent trials, it is important to separate out and accurately document complications. One of these complications that is usually related to the endovascular intervention is Infarct in New Territory (INT). We propose a standardized methodology for documenting INT after the procedure. This new classification takes into account variations in vascular anatomy and location of the occlusion. In addition, given that after the recent trials, vascular imaging (eg, CT angiography (CTA)) is now the standard of care in the work up of acute ischemic stroke, this classification utilizes the information on the pre-procedure non-invasive vascular imaging, the angiography images from end of procedure and the location of lesions on the follow-up scan.
