Insertion of cerebrospinal fluid (CSF) shunts in patients with idiopathic intracranial hypertension (IIH) is challenging mainly due to the small ventricles and phenotypical body habitus. In this report the authors present their surgical protocol for insertion of a ventriculoperitoneal shunt (VPS) in patients with IIH and the associated revision rates. ⋯ The components of the Birmingham standardized IIH shunt protocol are evidence based and address the technical challenges of CSF diversion in patients with IIH. This protocol is associated with a low revision rate, and the authors recommend standardization for CSF shunting in IIH.

Dural venous sinus stenting (VSS) is an effective intervention for patients with idiopathic intracranial hypertension (IIH) refractory to medical treatment. Our goal was to evaluate the efficacy by utilizing a large multi-institutional sample. ⋯ VSS is an effective and safe procedure resulting in significant improvement of headaches, visual impairment, dizziness, and tinnitus, acetazolamide and topiramate usage were lower after VSS in patients with IIH. The paucity of pre-VSS and post-VSS CSF shunt and ONSF procedure data does not provide enough evidence to establish significance.

Inflammatory atherosclerotic remodeling of unruptured intracranial aneurysms (UIAs) wall, which could be detected as aneurysm wall enhancement (AWE) in MR vessel wall imaging (VWI), plays a pivotal role in pathophysiology of progression to rupture. On the other hand, abdominal aortic calcification reflects the extent of systemic atherosclerosis, which in turn predicts the risk of atherosclerotic cardiovascular as well as cerebrovascular diseases. This study sought to investigate whether the abdominal aortic calcification was associated with increased wall enhancement of UIAs in VWI. ⋯ The ACV was significantly associated with increased wall enhancement of UIAs. Systemic atherosclerosis might be a risk factor for the instability of UIAs. Future studies examining the effect of medications for systemic atherosclerosis on the extent of AWE in UIAs is warranted.

To evaluate the usefulness and degree of perfusion abnormalities in pediatric head injury patients by using computed tomography perfusion (CTP) and to assess its co-relation with neurologic outcome based on Glasgow Outcome Scale Extended Pediatric revision (GOSE-P). ⋯ We conclude that CBF and MTT are 2 important radiologic parameters that can be used as prognostic indicators in pediatric head injury patients.

The microscopic transciliary SupraOrbital keyhole (mtSO) approach has been used for a wide variety of anterior and middle fossa pathologies, including aneurysms, meningiomas, craniopharyngiomas, and other skull-base tumors. Several clinical series have proven its efficacy and safety, but detailed anatomical demarcations of the anterior and middle cranial base exposure are lacking. Our aim was to define the surgical limitations of the mtSO approach to the ipsilateral and contralateral anterior and middle skull base. ⋯ Our findings define the surgical limitations of the mtSO approach for the treatment of anterior and middle cranial base pathologies. These limits can be reliably identified on imaging studies allowing assessment of exposure to guide preoperative case selection.
