The purpose of this study is to investigate the efficacy and safety of mechanical thrombectomy in patients with acute vertebrobasilar artery occlusion (VBAO) using the Trevo Stentriever™ device. ⋯ Thrombectomy in patients with acute VBAO using the Trevo Stentriever™-either as the sole device or in conjunction with other devices-is feasible and seems to be similarly effective and safe as in the anterior circulation compared to reported data in the literature.

Many studies have reported on vulnerable areas and neural tracts of the brain after hypoxic-ischemic brain injury (HI-BI). However, little is known about injury of the ascending reticular activating system (ARAS). We attempted to investigate on injury of the lower portion of the ARAS in patients with HI-BI using diffusion tensor tractography (DTT). ⋯ Injury of the lower portion of the ARAS was found between the pontine reticular formation and the thalamus in patients with impaired arousal after HI-BI. We believe that analysis using DTT could be helpful in the evaluation of patients with impaired arousal after HI-BI.

Infundibular dilation (ID) and aneurysm at the internal carotid artery (ICA)-posterior communicating artery (PComA) junction can be difficult to distinguish but may differ in clinical significance. The aim of this study was to evaluate the utility of CT angiography (CTA) in differentially diagnosing IDs and small unruptured aneurysms at the ICA-PComA junction. ⋯ CTA may be a useful noninvasive modality for differential diagnosis of ID and aneurysm at the ICA-PComA junction.
