This study was performed to analyze the outcome of multisession gamma knife radiosurgery (GKS) in benign tumors located at the orbital apex. ⋯ Multisession GKS proved to be an effective and safe management strategy for benign orbital apex tumors. Response to treatment was different according to the pathology, and multisession GKS may be considered as the initial treatment of choice for specific pathology such as cavernous hemangioma.

The endoscopic endonasal approach for pituitary neoplasms has shown similar efficacy compared with the microscopic approach. However, outcomes and complication rates with larger macroadenomas is not as well documented. This study addresses the efficacy and outcome of the fully endoscopic endonasal approach for large and giant pituitary adenomas. ⋯ Endoscopic endonasal resection of large and giant pituitary macroadenomas is safe and efficient. Postoperative complications, including cerebrospinal fluid leak, are low. Surgical efficacy of the fully endoscopic endonasal approach for large and giant macroadenomas makes the technique a preferable option in this subset of patients.

Subarachnoid hemorrhage (SAH) occasionally originates from extracranial arteries, and SAH caused by cervical trauma is even rarer. ⋯ In young adult patients with SAH of unexplained origin, we suggest that the cervical region be considered as the bleeding focus; in such cases, surgical evacuation of bleeding can save some patients.

Middle cerebral artery (MCA) aneurysms represent 20% of intracranial aneurysms. Most (80%) of them are located on the sylvian bifurcation, the seat of hemodynamic turbulence flow. Morbidity and mortality related to surgery of MCA aneurysms are not negligible. MCA vascularization areas are important eloquence functional territorial of Brain tissue. Indocyanine green videoangiography assistance (ICG-VA) is an emergent tool for intraoperative assessment of aneurysmal occlusion and for checking a possible stenosant clip in vascular area. The purposes of this study were to evaluate the safety of clipping procedure in terms of morbidity, mortality, and efficiency of aneurysm occlusion without using ICG-VA, recurrence and bleeding/rebleeding at short and long terms, and angiographic and clinical follow-ups. ⋯ Surgical management is relatively safe for patients, with an acceptable complication rate in the era when ICG-VA was not yet available. Indeed, the main source of procedural ischemia microsurgery is stenosant clip. To limit the occurrence of malposition, the author's center began using ICG-VA a few months ago and expects to reduce its rate of incomplete occlusion.

Deep brain stimulation (DBS) is a cost-effective strategy for the treatment of different neurologic disorders. However, DBS procedures are associated with high costs of implantation and replacement of the internal pulse generator (IPG). Different manufacturers propose the use of rechargeable IPGs. The objective of this study is to compare the implantation costs of nonrechargeable IPGs versus the estimated costs of rechargeable IPGs in different categories of patients to evaluate if an economic advantage for the health care system could be derived. ⋯ Implantation of rechargeable IPGs presents clinical advantages compared with nonrechargeable devices. A huge economic savings can be realized with the implantation of rechargeable IPGs in categories of patients implanted with IPGs for DBS.
