Statin Therapy Does Not Affect the Radiographic and Clinical Profile of Patients with TIA and Minor Stroke EDITOR'S CHOICE
CONCLUSIONS: Prestroke or early-stroke statin therapy was not associated with a reduction in the number of DWI lesions, infarct volume, or improved clinical or functional outcome at 3 months. The effect of acute statin treatment in patients with ischemic stroke/TIA remains unclear and needs further investigation.

Evaluating the use of gradient echo imaging for the detection of cerebral microbleeds in acute stroke cases: A retrospective data analysis in a UK stroke unit
Imaging in stroke, allows its classification into ischaemic stroke (IS) or intracranial haemorrhagic stroke (ICH), ensuring time-sensitive treatment to be administered. Imaging can also allow detection of cerebral microbleeds (CMBs), which may further determine pharmacological intervention in acute stroke. True gradient echo (T2 ∗GRE) or susceptibility weighted imaging (SWI) have high sensitivity for the detection of CMBs. These two sequences are included in the national guidelines; however, the implementation of these guidelines can vary depending on local interpretation and scanner capabilities.

Emergent extracranial internal carotid artery stenting and mechanical thrombectomy in acute ischaemic stroke.
CONCLUSIONS: Treatment of tandem extracranial ICA and intracranial occlusions in the setting of acute ischaemic stroke with extracranial carotid artery stenting followed by adjunctive intracranial mechanical thrombectomy is both safe and effective, but further evaluation of this treatment modality is necessary.

The Clinical and Radiographic Importance of Distinguishing Partial from Near-Complete Reperfusion Following Intra-Arterial Stroke Therapy INTERVENTIONAL
CONCLUSIONS: Significant differences exist in outcomes and infarct volumes between partial (TICI 2a) and near-complete (TICI 2b/3) reperfusion following intra-arterial stroke therapy. Further trials should separately report these groups to facilitate comparison among treatment paradigms.

Degree of Collaterals and Not Time Is the Determining Factor of Core Infarct Volume within 6 Hours of Stroke Onset FELLOWS' JOURNAL CLUB
CONCLUSIONS: Collateral status but not time from stroke onset to imaging was a predictor of the size of core infarct in patients with anterior circulation large-vessel occlusion presenting within 6 hours from onset.

Influence of carotid tortuosity on internal carotid artery access time in the treatment of acute ischemic stroke.
Conclusion Supraaortic vessel tortuosity significantly influences ICA-AT in mechanical thrombectomy for an acute large vessel. There furthermore was a trend for lower successful recanalization rates with increasing ICA-AT. PMID: 28944705 [PubMed - as supplied by publisher]

The Dilator-Dotter Technique: A Modified Method of Rapid Internal Carotid Artery Revascularization in Acute Ischemic Stroke INTERVENTIONAL
CONCLUSIONS: The dilator-Dotter technique may be a safe and effective modification of the traditional Dotter technique in allowing rapid ICA recanalization in cases of acute ischemic stroke due to tandem occlusions.

Dual antiplatelet use in the management of COVID-19 associated acute ischemic stroke reocclusion
CONCLUSION: COVID-19 AIS may be associated with a hypercoagulable state which risks malignant reocclusion complicating MT. We found antithrombotic treatment periprocedural cangrelor with or without argatroban transitioned to oral aspirin with ticagrelor to be a viable method for management of these patients.PMID:35549746 | DOI:10.1177/15910199221097484

Imaging Characteristics of Cerebrovascular Arteriopathy and Stroke in Hutchinson-Gilford Progeria Syndrome PEDIATRICS
CONCLUSIONS: We report a unique intracranial and superior cervical arteriopathy in HGPS distinct from other vasculopathies of childhood, such as Moyamoya, and cerebrovascular disease of aging, including atherosclerosis. Arterial features of the mid and lower neck are less distinctive. For the first time, we identified early and clinically silent strokes as a prevalent disease characteristic in HGPS. Longitudinal analysis of stroke incidence and vasculopathy may provide an outcome measure for future treatment interventions for children with HGPS.

Portal–Left Atrium Shunt Leading to Stroke
A 37-year-old man presented acutely with a stroke, ataxia, and left upper limb weakness. His medical history was positive for congenital low-grade liver fibrosis and for a single episode of paresthesia of the left upper limb (4 y previously). Magnetic resonance imaging showed acute ischemic lesions in the right cerebellum and temporal region (). Chest radiography, blood tests, and echocardiography were normal. Computed tomography demonstrated dilatation of the portal vein and gastroesophageal varix arising from the left gastric vein (arrowhead) and reaching the left atrium (arrow), which is partially contrasted in the veno...

FLAIR Vascular Hyperintensity is a Surrogate of Collateral Flow and Leukoaraiosis in Patients With Acute Stroke Due to Proximal Artery Occlusion
CONCLUSIONSFVH score detected on acute MRI can be used as a surrogate of collateral flow grade in AIS patients. FVH degree is inversely associated with WMHV, possibly signifying diffuse disease of cerebral vasculature in patients with severe leukoaraiosis.
