We introduce a technique that uses intraoperative flat-panel detector computed tomography (FD-CT) and three-dimensional rotational angiography (3D-RA) acquired in the hybrid operative suite to provide full neuronavigation capabilities during cerebrovascular surgery without the use of preoperative imaging studies. ⋯ Hybrid operating suites equipped with FD-CT, 3D-RA, and NNS capabilities can be used to provide intraoperative 3D image guidance during cerebrovascular surgery with excellent accuracy and without the need for preoperative angiography. Furthermore, this technique required less than 15 minutes for image acquisition and utilizes digitally subtracted angiographic images that are superior to conventional CT or MRI for the imaging of cerebrovascular pathology.

Review Meta Analysis
Neurotrauma outside the high-income setting: a review of audit and data-collection strategies.
To review the sparse literature that exists on the topic of head injury assessment and management outside high-income settings and attempt to: 1) identify strengths and weaknesses of the currently published clinical data relating to head injuries in lower-income countries; and 2) consider specific objectives for future head injury research in the resource-limited setting. If levels of excellence in neurosurgery are to be sustainably achieved outside high-income countries, there must be good systems of research and audit in place both to identify where development is needed and to evaluate the efficacy of development projects already in progress. ⋯ The use of standardized scoring systems and outcome measures is likely to improve the comparability of data between studies. A multicenter collaborative approach towards data collection in resource-limited settings may be the most efficient and productive strategy for future research.

Multicenter Study Comparative Study
Comparisons of 30-day mortalities and 90-day functional recoveries after first and recurrent primary intracerebral hemorrhage attacks: a multiple-institute retrospective study.
The aim of this study was to determine and compare 30-day mortalities and 90-day functional recoveries after first and recurrent primary intracerebral hemorrhage (PICH) attacks. The investigators sought to identify factors predisposing 30-day mortality and functional recovery and to compare patients after first and recurrent PICH attacks. ⋯ The factors found to predispose clinical outcome were similar in the two groups. This study shows that given optimal treatment, recurrent PICH patients can achieve the same clinical outcomes as first PICH patients.

The outcome of patients with aneurysmal subarachnoid hemorrhage (SAH) has improved slowly over the past 25 years. This improvement may be due to early aneurysm repair by endovascular or open means, use of nimodipine, and better critical care management. Despite this improvement, mortality remains at about 40%, and many survivors have permanent neurologic, cognitive, and neuropsychologic deficits. ⋯ The primary aim of the SAHIT data repository is to provide a unique resource for prognostic analysis and for studies aimed at optimizing the design and analysis of phase III trials in aneurysmal SAH. With this aim in mind, we convened a multinational investigator meeting to explore merging individual patient data from multiple clinical trials and observational databases of patients with SAH and to create an agreement under which such a group of investigators could submit data and collaborate. We welcome collaboration with other investigators.
