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...

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...
