Background and purpose Stroke recurrence is high in patients with symptomatic intracranial stenosis despite best medical treatment. Based on evidence from past studies using previous stent generations ...

Background We investigate the association of imaging biomarkers extracted from fully automated body composition analysis (BCA) of computed tomography (CT) angiography images of endovascularly treated ...

Background Blebs significantly increase rupture risk of intracranial aneurysms. Radiomic analysis offers a robust characterization of the aneurysm wall. However, the unique radiomic profile of various ...

Background Previous data on the prevalence of unruptured intracranial aneurysms (UIAs) vary widely, and studies based on these data are plagued with unintentional bias. Accurate prevalence data are ...

Background Osteoporotic vertebral compression fractures (OVCFs) of the lumbar region may be accompanied by thoracic fractures. Treating only the lumbar fractures can lead to worsening of the thoracic ...

Background Carotid blowout syndrome is a serious complication of head and neck cancer (HNC) that may involve the intracranial or extracranial internal carotid artery (ICA). Although parent artery ...

Objective To investigate the intracranial manifestations of these changes in patients with cerebral venous outflow disorders (CVD). Methods A retrospective chart review was conducted on 22 consecutive ...

Background In patients with refractory intracranial atherosclerotic disease (ICAD), percutaneous transluminal balloon angioplasty (PTBA) is less complex but typically results in higher postprocedural ...

Background Congress enacted the No Surprises Act (NSA) in 2021. The NSA relies on the ability for providers to appeal their out-of-network (OON) payment through an arbitration process known as ...

Background The angiographic shape of an occlusion, like the clot meniscus sign and the claw sign, has been reported to potentially impact the recanalization rate and clinical outcome in patients ...

Background Despite the increasing use of non-invasive imaging, DSA remains the gold standard for cerebrovascular imaging. However, trends in DSA utilization are poorly understood. The goal of this ...

Background Temporary clipping (TC) is an essential adjunct in cerebral aneurysm (CA) surgery. Despite appearing insignificant to the surgeon under the microscope, TC may cause parent vessel injury.
