Treatment of an Acute Common Carotid Artery Occlusion Using a Large-Bore Aspiration Thrombectomy Device
An 86-year-old man presented with acute ischemic stroke in the left middle cerebral artery territory due to complete occlusion of the left common carotid artery (CCA) extending into the left internal and external carotid artery up to the carotid terminus (C7) (Fig 1). The etiology was surmised to be cardioembolic, in the setting of atrial fibrillation with subtherapeutic anticoagulation (international normalized ratio, 1.8). After presentation, the National Institutes of Health Stroke Scale (NIHSS) score increased from 4 (baseline) to 8 points; mechanical recanalization by percutaneous thrombus aspiration was planned.

MRI and Traumatic Brain Injury: Where Are We Heading?
Traumatic brain injury (TBI) is currently very much in the public consciousness. A quick Google search reveals over 150 million TBI-related hits, including several National Institute of Neurological Disorders and Stroke, Department of Defense, and even National Football League (NFL) funded initiatives, such as the National Institutes of Health –sponsored TRACK-TBI study. I was therefore delighted when Drs Maralani and Symons invited me to write this introduction for their issue on “MRI and Traumatic Brain Injury,” for this issue of the Neuroimaging Clinics series.

Basilar artery occlusion: A review of clinicoradiologic features, treatment selection, and endovascular techniques
Interv Neuroradiol. 2022 Jun 12:15910199221106049. doi: 10.1177/15910199221106049. Online ahead of print.ABSTRACTBasilar artery occlusion (BAO) is an infrequent but often fatal subtype of stroke. Predicting outcomes and selecting patients for endovascular therapy (EVT) remains challenging. Advances in neuroimaging and the development of prognostic scoring systems have augmented clinical decision-making over time. Recent randomized trials, BEST (Basilar Artery Occlusion Endovascular Intervention vs. Standard Medical Treatment), BASICS (Basilar Artery International Cooperation Study), BAOCHE (Basilar Artery Occlusion CHinese...

Risk and Benefit Evaluation: Application of Multiphase Computed Tomography Angiography in Mechanical Thrombectomy for Patients With Acute Ischemic Stroke
The objective of this study was to evaluate the collateral circulation in patients with acute ischemic stroke (AIS) by multiphase computed tomography angiography (mCTA) and explore its application value in the risk and benefit assessment after thrombectomy. Methods Clinical and imaging parameters of AIS patients who underwent thrombectomy were consecutively collected. The 90-day modified Rankin Scale (mRS) score was used as the standard for evaluating the recovery of neurological functions. The receiver operating characteristic curve and correlation analysis were used to evaluate the diagnostic efficacy of collatera...

Texture analysis based on ADC maps and T2-FLAIR images for the assessment of the severity and prognosis of ischaemic stroke
To explore the feasibility of texture analysis based on T2-weighted fluid-attenuated inversion recovery (T2-FLAIR) images and apparent diffusion coefficient (ADC) maps in the assessment of the severity and prognosis of ischaemic stroke using the National Institutes of Health Stroke Scale (NIHSS) and modified Rankin scale (mRS) scores, respectively.

Endovascular repair of an acute symptomatic carotid artery dissection through the false dissecting carotid lumen.
Authors: Befera N, Griffin AS, Hauck EF Abstract A 48-year-old woman presented with an acute ischemic stroke (National Institutes of Health Stroke Scale (NIHSS) 21) six hours after symptom onset. Workup revealed a left cervical internal carotid artery (ICA) occlusive dissection, which was emergently reconstructed with a flow-diverting stent. A routine Duplex scan one hour later suggested reocclusion of the ICA, confirmed by angiography. The true lumen of the ICA could not be accessed and therefore the "false lumen" of the ICA dissection was entered proximally. The true lumen and ultimately the flow-diverting stent ...

Compliant balloon angioplasty for the treatment of internal carotid artery dissection.
This report describes the innovative management of a severe haemodynamic stroke related to an occlusive extracranial internal carotid artery dissection. Intravenous thrombolysis combined with endovascular treatment were undertaken on the basis of a total mismatch profile (National Institutes of Health stroke scale (NIHSS) score of 27 and infarct volume on diffusion-weighted imaging of 0 mL). Balloon angioplasty using a long and compliant balloon microcatheter allowed complete recovery of the intracranial blood flow. The patient showed dramatic clinical improvement (day 1, NIHSS 5) and favourable functional outcome (day 9...

Successful endovascular recanalization of a partially occluded basilar artery fenestration.
Authors: Meinel TR, Pult F, Gralla J, Arnold M, Bassetti C, Jung S Abstract A 76-year-old man with a history of arterial hypertension, obstructive sleep apnea, dyslipidemia, family history of cardiovascular events, prestroke and overweight presented 90 minutes after acute onset of right-sided sensorimotor hemiparesis, hemiataxia and dysarthria (National Institutes of Health Stroke Scale (NIHSS) 9/42). Magnetic resonance imaging (MRI) revealed a pontine ischemia and MR angiography showed a thrombus in the middle to distal portion of the basilar artery. Owing to the location, an occlusion of one lumen of a fenestrate...

Telestroke Imaging: A Review
ABSTRACT The use of telecommunications technology to provide the healthcare services, telemedicine, has been in use since the 1860s. The use of technology has ranged from providing medical care to far‐off places during wartimes to monitoring physiological measurements of astronauts in space. Since the 1990s, reports have been published on diagnoses of neurological diseases with the use of video links. Studies confirm that the neurological examinations, including the National Institutes of Health Stroke Scale, performed during teleneurology are dependable. The transfer of stroke patients in rural hospitals to bigger medic...
