Prevalence of unruptured intracranial aneurysms (UIAs) examined in the trauma population
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 ...

Improved technical outcomes with converting thrombectomy techniques after failed first pass recanalization
Background A higher number of recanalization attempts reduces the efficacy of endovascular thrombectomy (EVT) for acute ischemic stroke secondary to large vessel occlusion (LVO). We assessed the ...

Effects of different endovascular treatments on cerebral perfusion changes and stroke recurrence in patients with intracranial atherosclerosis
Background In patients with refractory intracranial atherosclerotic disease (ICAD), percutaneous transluminal balloon angioplasty (PTBA) is less complex but typically results in higher postprocedural ...

Cerebral venous pressures, sinus trans-stenosis gradients, and intracranial pressures are dramatically augmented by head position
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 ...

The need for thoracic magnetic resonance imaging before vertebral augmentation surgery in patients with lumbar vertebral fractures
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 ...

Vessel wall MRI evaluation for the safety of endovascular recanalization of non-acute intracranial anterior circulation artery occlusions
Background Vessel wall MRI (VWMRI) can reveal the morphological features of intracranial artery occlusion (ICAO). This study aimed to investigate the imaging features of ICAO on VWMRI and explore ...

Intraoperative cerebral angiography reveals microsurgically occult sequelae of temporary clip application during elective cerebral aneurysm surgery
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.

Radiomic profiling of high-risk aneurysms with blebs: an exploratory study
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 ...

Neurointerventional payment for out-of-network mechanical thrombectomy in the era of the No Surprises Act
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 ...

Endovascular thrombectomy for large ischemic strokes: meta-analysis of six multicenter randomized controlled trials
Background Six randomized controlled trials have concluded their investigations on the efficacy and safety of endovascular thrombectomy (EVT) for patients with large infarcts. To synthesize the ...

Rupture risk assessment in cerebral arteriovenous malformations: an ensemble model using hemodynamic and morphological features
Background Cerebral arteriovenous malformation (AVM) is a cerebrovascular disorder posing a risk for intracranial hemorrhage. However, there are few reliable quantitative indices to predict hemorrhage ...

Combined collaterals and hemodynamic features to predict the prognosis in acute ischemic stroke patients undergoing mechanical thrombectomy
Background Despite successful recanalization via mechanical thrombectomy (MT), only half of acute ischemic stroke (AIS) patients achieve functional independence. Post-MT hemodynamic features are ...
