A method of guiding an intermediate catheter from a new alpha-type guiding catheter placed in the ascending aorta to the carotid artery is evaluated in neuroendovascular treatment in challenging anatomic directions of the guiding catheter, such as the bovine aortic arch and type III aortic arch. ⋯ The 8-Fr alpha shape guiding catheter quickly guides the inner catheter into the bovine and the type III aortic arch by looking up from the ascending aorta.

Thrombolysis (rTPA) and mechanical thrombectomy (MT) are cost-effective treatments for ischemic stroke. However, little is known about the impact of different types of health systems (HSs) on the outcome and cost of ischemic stroke. ⋯ MT and rTPA are independently cost-effective among different HS.

To obtain the quantitative measurements of the muscle morphology of cervical extensors in patients with multilevel cervical spondylotic myelopathy, and determine whether the morphological parameter of each muscle correlates with the patients' demographic features, symptoms, and cervical sagittal balance. ⋯ In patients with multilevel CSM, age and sex were demographic factors that were highly correlated with muscle morphology changes. Extensor muscles, especially DEM, play important roles in maintaining cervical sagittal balance and are associated with the severity of neck symptoms.

Blunt cerebrovascular injury (BCVI), defined as blunt traumatic injury to the carotid or vertebral arteries, is associated with significant risk of stroke and mortality. Cervical spine trauma is a recognized risk factor for BCVI. ⋯ While BCVI is rare following cervical spine injury due to blunt trauma, it is a significant predictor of stroke and mortality. The risk factors associated with BCVI, stroke, and mortality identified here should be used in the development of more effective predictive tools to improve care.

Solitary fibrous tumor/hemangiopericytoma (SFT/HPCT) is a rare tumor characterized by high recurrence rate and metastatic potential, even after surgical resection. We report on the clinical outcomes and risk factors for metastasis and progression-free survival (PFS) of patients diagnosed with SFT/HPCT. ⋯ Our data demonstrate a strong association between male sex and the outcomes of shorter PFS and higher risk for metastases. Further research is warranted to understand the clinical characteristics and outcomes of this rare tumor.
