BACKGROUND AND PURPOSE: Not all tandem occlusions diagnosed on traditional
vascular imaging modalities, such as MRA, represent actual complete ICA occlusion. This …

Background High-resolution vessel wall imaging (HR-VWI) can provide information about
exact occluded length, etiology, and the presence of intraluminal thrombus or residual …

ABSTRACT BACKGROUND Differentiation between true acute tandem occlusion involving
the extracranial internal carotid artery (ICA) from pseudotandem occlusion with a patent …

Background and Purpose—The National Institutes of Health Stroke Scale (NIHSS) is
predictive of thrombus presence but has limited ability to identify occlusion location in the …

Background and Purpose: Differentiation between pseudo-occlusion and true occlusion of
internal carotid artery (ICA) is important in treatment planning for acute ischemic stroke …

Introduction A debate is emerging over whether the treatment time window in acute stroke
can be extended beyond 6 h if penumbral tissue can be identified. Treatment decisions are …

In cases of acute stroke, differentiation between an occluded and a patent internal carotid
artery (ICA) is crucial for diagnosis and management. Although CT angiography (CTA) can …

Background and Purpose—Our study evaluated noninvasive tests for the diagnosis of
atheromatous internal carotid artery (ICA) pseudo-occlusion. Methods—Twenty patients (17 …

Background We aimed to analyze angiographic and clinical outcomes according to the
sequence of treatment (antegrade versus retrograde) in patients with acute ischemic stroke …

Background and Purpose—To determine the accuracy of multislice computed tomographic
(CT) angiography in diagnosing total versus near occlusions of the internal carotid artery …
