Interpretable Machine Learning Modeling for Ischemic Stroke Outcome Prediction
ConclusionMachine learning that is applied to quantifiable image features from CT and CTA alongside basic clinical characteristics constitutes a promising automated method in the pre-interventional prediction of stroke prognosis. Interpretable models allow for exploring which initial features contribute the most to post-thrombectomy outcome prediction overall and for each individual patient outcome.

The FAST VAN for Field Identification of Large Vessel Occlusion in Acute Stroke
DISCUSSION: The FAST VAN tool for identification of LVO meets desired characteristics of an effective screening tool in ease of use, efficiency, and accuracy. Aphasia remains the most challenging cortical feature to identify accurately.PMID:35581931 | DOI:10.1017/cjn.2022.32

Endovascular Revascularization of Multi Segment Chronically Occluded ICA
This case report describes a novel endovascular method for treating chronically occluded internal carotid artery (COICA). The patient is a 55-year-old male with vascular risk factors who presented to an outside institution with right-sided weakness and dysarthria, was diagnosed as having a stroke, and discharged with medical management. The patient's symptoms failed to improve throughout the week prompting him to visit another outside institution, where computed tomography (CT) angiography showed bilateral occlusion of the ICAs at their origins extending intracranially.

Carotid Micromesh Stent for the Cervical Carotid Artery Dissecting Aneurysm in a Patient with Vascular Eagle Syndrome
A 38-year-old man was brought to the emergency room with sudden onset of aphasia and right hemiplegia. Magnetic resonance imaging (MRI) (Fig. 1A, B) showed an occlusion in the left middle cerebral artery (MCA) and left frontal and parietal lobes infarction. Cerebral angiography (Fig. 1C) showed a cervical carotid artery (CCA) dissecting aneurysm and stenosis. The superior trunk of the left MCA was occluded. The patient underwent emergent thrombectomy. The occluded artery was partially recanalized.

Association of Systolic Blood Pressure and Cerebral Collateral Flow in Acute Ischemic Stroke by Stroke Subtype
ConclusionsElevated initial SBP was associated with poor cerebral collateral flow and more severe symptoms in the CE group, but not in the LAA group in patients with AIS-LVO. These findings suggest differential effects of initial SBP elevation on collateral flow by stroke subtypes.

Filling Defect of Ipsilateral Transverse Sinus in Acute Large Artery Occlusion
ConclusionFilling defect of the ipsilateral transverse sinus was associated with edema expansion and an unfavorable outcome irrespective of the baseline arterial collateral status in patients with acute LAO, indicating that FDITS may be an important stroke-related prognostic imaging marker.

Predictors and Outcomes of Salvaging the Corticospinal Tract After Thrombectomy in Basilar Artery Occlusion Stroke
ConclusionCST salvage was associated with good functional outcomes in patients with BAO treated with thrombectomy. The presence of atrial fibrillation, location and length of BAO may predict CST salvage after thrombectomy, and rapid treatment with thrombectomy may protect this eloquent tract in these patients.

Hypoperfusion Intensity Ratio is Associated with Stroke Mechanism in Patients Undergoing Mechanical Thrombectomy
Hypoperfusion Intensity Ratio (HIR), defined as Tmax>10s/Tmax>6s on computed tomography perfusion (CTP), and stroke mechanisms have been independently correlated with angiographic collaterals and patient outcomes. Slowly developing atherosclerotic stenosis may foster collateral development, whereas cardioembolic occlusion may occur before collaterals mature. We hypothesized that favorable HIR is associated with large artery atherosclerosis (LAA) stroke mechanism and good clinical outcome.

Stroke and the Bovine Aortic Arch: Incidental or Deliberate ? A Comparative Study and our Experience
Conclusions: Bovine aortic arch is a risk factor for young-onset anterior circulation stroke. Bilateral and left-sided infarcts were more common. Endovascular procedures are difficult to perform through conventional routes, so brachioradial access is preferred.
