The new MRI modalities "BPAS and VISTA" for the diagnosis of VA dissection.
Recently VA dissection has drawn attention as a relatively common cause of stroke because of the introduction of MRI as a diagnostic technique. Basiparallel anatomic scanning (BPAS) was designed to visualize the surface appearance of the vertebrobasilar artery within the cistern. Volumetric isotropic TSE acquisition (VISTA) is a sort of black blood imaging method to evaluate the arterial wall and lumen. In this study, we aimed to evaluate the efficacy of the new MRI modalities "BPAS and VISTA," and to present a retrospective analysis of our experience with the diagnosis. ⋯ Dilatation of the external diameter was shown highly frequently in VA dissections. In addition, a discrepancy between BPAS and MRA as well as the intramural hematoma on VISTA was found comparatively frequently. BPAS and VISTA are minimally invasive and useful methods as screening tests.

Improving patient safety in the intra-operative MRI suite using an on-duty safety nurse, safety manual and checklist.
This paper describes the use of an on-duty safety nurse, a surgical safety manual and a checklist as an essential precursor to evaluating how these approaches affect surgical quality, communication in surgery crews and contribute to the safety of surgical care in the intra-operative magnetic resonance imaging (MRI) suite.

Case ReportsIntraoperative MRI (ioMRI) in the setting of awake craniotomies for supratentorial glioma resection.
Both awake craniotomy under conscious sedation and use of intraoperative MRI can increase the efficiency and safety of glioma resections. In contrast to craniotomies under general anesthesia, neurosurgery under conscious sedation requires several changes to the routine operative setup when performed in the ioMRI environment. ⋯ Seven patients underwent awake-craniotomies for resection of supratentorial gliomas using ioMRI at the Ohio State University Medical Center and James Cancer Hospital by a single surgeon. ioMRI can be safely employed in patients who are undergoing craniotomies under conscious sedation. Particularly important is the evaluation by the anesthesiologist whether the patient is a good candidate to sustain a likely longer than average procedure in a setting where his active cooperation is not only required, but also the essential aspect of this procedure.

Comparative StudyComparison of nimodipine delivery routes in cerebral vasospasm after subarachnoid hemorrhage: an experimental study in rabbits.
nimodipine is the most widely preferred and administered calcium channel blocker in cerebral vasospasm prevention and treatment. There is no experimental or clinical study investigating the comparative effects of routine treatment modalities. ⋯ this is the first study to show the most effective drug delivery route in CVS after SAH. Nimodipine treatment in cerebral vasospasm is useful. This study showed that selective IA nimodipine treatment and IT nimodipine treatment must be preferred to IV and oral treatments of chronic vasospasm following SAH.

The prediction of 30-day mortality and functional outcome in spontaneous intracerebral hemorrhage with secondary ventricular hemorrhage: a score comparison.
The original ICH (oICH) score was tested in different populations and showed good accuracy in the prediction of outcome and 30-day mortality after spontaneous ICH. The oICH was developed to stratify patients with all types of spontaneous intracerebral hemorrhage (SICH). Several modifications of the oICH score exist in the literature. ⋯ The best AUC for functional outcome was observed for the mICH-B score (0.823). For the mICH-A and the IVH score, an AUC of 0.811 was calculated. The scores that include the quantification of IVH or the grading of hydrocephalus show good accuracy in the prediction of 30-day mortality and functional outcome at 6 months in SICH with secondary IVH.
