This study analyzes the results of surgical treatment in 377 patients with colloid cysts (CCs) of the third ventricle who were treated at the Burdenko Neurosurgery Institute from 1981 to 2015. Operations were performed by a single surgeon (the first author of the article). ⋯ We made a preliminary assessment of the reasonability of the infratentorial supracerebellar approach for removal of CCs in 10 cases.

Dissecting aneurysms of the basilar artery (BA) are rare lesions, and the management of them has been controversial and challenging. The treatment becomes much more difficult when the patient has a disorder such as aortitis syndrome, which makes cerebral arteries occluded and tortuous. We describe a case of a ruptured BA dissecting aneurysm associated with aortitis syndrome, successfully treated with hybrid neurovascular surgery. ⋯ To our knowledge, this is the first report of hybrid neurovascular surgery for a BA dissecting aneurysm. A ruptured BA dissecting aneurysm in a patient with aortitis syndrome was successfully treated with hybrid neurovascular surgery.

Hemodynamics in cerebral aneurysms are currently investigated toward clinical efficacy using nonstandardized computational simulation techniques. At the same time, flow patterns and velocities are accessible by 4-dimensional phase contrast magnetic resonance imaging (4D pcMRI). Complexity of protocol design and imaging duration has limited the use of this technique in clinical imaging. A new approach is presented to overcome these limitations. ⋯ 4D pcMRI flow imaging in cerebral aneurysms within a time frame suitable for clinical imaging applications is feasible with optimized acquisition parameters, thereby enabling quantification of intra-aneurysmal flow changes after flow diverter device treatment.

The association between obesity and nontraumatic subarachnoid hemorrhage (SAH) patient outcome is unclear. The aim of this study was to determine the impact of morbid obesity (body mass index ≥40 kg/m2) on nontraumatic SAH outcomes. ⋯ Morbid obesity is associated with increased LOS, hospital costs and charges and with acute respiratory failure. However, it is also associated with a decrease in hospital mortality.
