Completeness of the circle of Willis and risk of ischemic stroke in patients without cerebrovascular disease
Conclusions An incomplete anterior CoW combined with an incomplete posterior CoW is related to future anterior circulation stroke. CoW completeness has no large effect on the relation between asymptomatic ICA stenosis/occlusion and future stroke.

Value of CT angiography in anterior circulation large vessel occlusive stroke: Imaging findings, pearls, and pitfalls
Publication date: July 2015 Source:European Journal of Radiology, Volume 84, Issue 7 Author(s): Sarah Power , Sinead H. McEvoy , Jane Cunningham , Joanna P. Ti , Seamus Looby , Alan O'Hare , David Williams , Paul Brennan , John Thornton Hyperacute stroke imaging is playing an increasingly important role in determining management decisions in acute stroke patients, particularly patients with large vessel occlusive stroke who may benefit from endovascular intervention. CT angiography (CTA) is an important tool in the work-up of the acute stroke patient. It reliably detects large occlusive thrombi in proximal cerebral arter...

Presence and extent of coronary calcified plaque evaluated by coronary computed tomographic angiography are independent predictors of ischemic stroke in patients with suspected coronary artery disease
Abstract Although ischemic stroke and coronary artery disease (CAD) share common risk factors and pathophysiology, the risk of stroke in patients with CAD remains unclear. We sought to evaluate the risk of ischemic stroke in patients with suspected CAD according to coronary computed tomographic angiography (CCTA) and single-photon emission computed tomography (SPECT) findings. Presence, severity, and extent of CAD were evaluated in 1137 patients with suspected CAD who underwent CCTA and SPECT. Primary outcome was the occurrence of ischemic stroke. During follow-up (median 26 months), ischemic stroke was obse...

Vessel Wall Enhancement on Black-Blood MRI Predicts Acute and Future Stroke in Cerebral Amyloid Angiopathy FUNCTIONAL
CONCLUSIONS: Vessel wall enhancement is associated with both acute and future stroke in patients with cerebral amyloid angiopathy.

Prediction of the Multisegment Clot Sign on Dynamic CT Angiography of Cardioembolic Stroke ADULT BRAIN
CONCLUSIONS: The presence of the multisegment clot sign on dynamic CTA specifically indicates intracranial large-artery occlusion caused by an embolism from a cardiac source, which may be useful for acute management and secondary prevention of stroke.

Diagnostic Accuracy of Electrocardiogram-Gated Thoracic Computed Tomography Angiography without Heart Rate Control for Detection of Significant Coronary Artery Stenosis in Patients with Acute Ischemic Stroke: A Comparative Study.
Conclusion: Electrocardiogram-gated TCTA without HR control facilitates the identification of significant coronary stenosis in patients with ischemic stroke. PMID: 30174480 [PubMed - in process]

Consensus Statements by Korean Society of Interventional Neuroradiology and Korean Stroke Society: Hyperacute Endovascular Treatment Workflow to Reduce Door-to-Reperfusion Time.
Authors: Kim DH, Kim B, Jung C, Nam HS, Lee JS, Kim JW, Lee WJ, Seo WK, Heo JH, Baik SK, Kim BM, Rha JH Abstract Recent clinical trials demonstrated the clinical benefit of endovascular treatment (EVT) in patients with acute ischemic stroke due to large vessel occlusion. These trials confirmed that good outcome after EVT depends on the time interval from symptom onset to reperfusion and that in-hospital delay leads to poor clinical outcome. However, there has been no universally accepted in-hospital workflow and performance benchmark for rapid reperfusion. Additionally, wide variety in workflow for EVT is present b...

Mechanical Thrombectomy Using the New ERIC Retrieval Device Is Feasible, Efficient, and Safe in Acute Ischemic Stroke: A Swiss Stroke Center Experience INTERVENTIONAL
CONCLUSIONS: In this observational study, the new ERIC retrieval device was technically feasible, safe, and effective in acute ischemic stroke with large-vessel occlusion.

Stroke Recurrence in Children with Vertebral Artery Dissecting Aneurysm PEDIATRICS
CONCLUSIONS: Vertebral artery dissecting aneurysm is often missed on the initial diagnostic evaluation of children presenting with stroke. In children with vertebral artery dissection, the presence of an aneurysm is associated with stroke presentation at a younger age and stroke recurrence.

Comparison of carotid artery calcification between stroke and nonstroke patients using CT angiographic and panoramic images
CONCLUSIONS: On both CTA and panoramic images, although CAC is found more frequently in the stroke group, vessel-outlined shaped CAC in the nonstorke group shows significant differences compared to other shapes.PMID:35925038 | DOI:10.1259/dmfr.20210500
