The pterional/frontotemporal orbitozygomatic (FTOZ) approaches are the 2 most widely used procedures for resection of sphenoid wing meningiomas; however, a comparison of outcomes and complications of these 2 approaches has not been well described yet. Here, we investigated the outcomes, complications, and predictors of favorable outcomes of these 2 approaches. ⋯ In summary, sphenoid wing meningiomas undergoing extensive skull base approach (FTOZ) and GTR had a low recurrence rate and greater RFS. Even though FTOZ with GTR is preferable to resect the sphenoid wing meningiomas, the procedure should be tailored to each patient depending on the risks and surgical morbidity.

We previously showed that cervical pedicle screw (CPS) placement is safe even with the freehand technique. The posterolateral fusion rate 1 year after CPS placement, as measured by computed tomography (CT), is reported here. The graft resorption rates when different graft materials were used were also analyzed. ⋯ CPS placement yielded a posterolateral cervical fusion rate of 98.2%. Despite the high resorption rate of allograft only, this material yielded fusion rates that were similar to those of the other materials. Thus, the strong fixation power of CPS might compensate for the delayed fusion and high resorption rates of allograft bone chips.

The Potentially Fatal Ogilvie's Syndrome in Lateral Transpsoas Access Surgery: A Multi-Institutional Experience with 2930 patients.
Ogilvie's syndrome (OS) is a relatively uncommon pathology characterized by significant colonic dilation in the absence of mechanical obstruction. If unrecognized and untreated, cecal perforation resulting in a mortality rate of 25%-71% may occur. It is a potentially underdiagnosed condition in the lateral transpsoas approach population because of its uncommon nature and imitation of other well-known pathologies. ⋯ Ogilvie's syndrome is a rare but potentially fatal complication that can mimic a postoperative ileus. It is likely underdiagnosed in the lateral transpsoas approach population because of its uncommon nature and a high index of suspicion should remain. Neostigmine can be administered safely under close observation with immediate and successful outcomes. Patients with perforation require urgent laparotomy and primary repair.

Occurrence of cerebral vasospasm after onset of aneurysmal subarachnoid hemorrhage (SAH) is a critical factor determining clinical prognosis. Eicosapentaenoic acid and docosahexaenoic acid, both ω-3 fatty acids (ω-3FA), can suppress cerebral vasospasm, and docosahexaenoic acid can relax vessel vasoconstriction and have neuroprotective effects. We investigated whether administration of ω-3FA prevented cerebral vasospasm occurrence and improved clinical outcomes after aneurysmal SAH. ⋯ Administration of ω-3FA after aneurysmal SAH may reduce the frequency of cerebral vasospasm and may improve clinical outcomes.

The PulseRider® for the treatment of wide-neck bifurcation intracranial aneurysms: 6 months results.
PulseRider is a new endovascular stent dedicated to treat bifurcation intracranial aneurysms with a wide neck. Our purpose was to evaluate 6-month clinical and anatomic results of the device when used to facilitate endovascular coiling of wide-neck bifurcation aneurysms. ⋯ The PulseRider allows endovascular treatment of wide-neck bifurcation intracranial aneurysms. Larger series are needed to confirm our preliminary results.
