Comparative Study
Endovascular surgery for proximal posterior inferior cerebellar artery aneurysms: an analysis of Glasgow Outcome Score by Hunt-Hess grades.
Proximal posterior inferior cerebellar artery (PICA) aneurysms represent a subset of posterior circulation aneurysms that can be routinely treated with either clipping or coiling. The literature contains limited numbers of patients with proximal PICA aneurysms treated with endovascular surgery. We report our experience with endovascular surgery of proximal PICA aneurysms with emphasis on patients with poor Hunt-Hess grades. ⋯ This series demonstrates the safety and efficacy of endovascular surgery for proximal PICA aneurysms. Many patients with poor Hunt-Hess grades from ruptured PICA aneurysms ultimately had a good outcome. This could be secondary to early, aggressive treatment of hydrocephalus and the minimally invasive nature of the endovascular approach.

Comparative Study Clinical Trial
Subpectoral implantation of the vagus nerve stimulator.
To report the technique of subpectoral (SP) implantation of the vagus nerve stimulator (VNS) generator. ⋯ The SP implantation technique provides an attractive alternative to SQ VNS implantation. With increased soft tissue coverage, we provide improved cosmesis, increased wound durability to tampering and trauma, and a comparable infection rate with the SQ group.

Embolization is an important therapeutic modality in the multidisciplinary management of arteriovenous malformations (AVM); however, prior series have reported a wide variability in overall complication rates caused by embolization (10-50% neurological deficit, 1-4% mortality). In this study, we reviewed our experience with AVM embolization and analyzed factors that might predict complications and clinical outcomes after AVM embolization. ⋯ In a single-center, retrospective, nonrandomized study, 90.5% of patients had excellent or good outcomes after AVM embolization, with a complication rate lower than previously reported. Spetzler-Martin grade III to V and periprocedural hemorrhage were the most important predictive factors in determining outcome after embolization.

Comparative Study Clinical Trial
Endoscopic endonasal approaches for repair of cerebrospinal fluid leaks: nine-year experience.
To describe surgical endoscopic experience in the repair of cerebrospinal fluid leaks treated by transnasal approaches. ⋯ The target of endoscopic endonasal technique in the repair of cerebrospinal fluid leaks is to ensure a stable duraplasty with the least invasive approach avoiding craniotomy. A correct diagnosis surely allows the choice of the best treatment, surgical approach, graft, and technique. Our multidisciplinary approach to this pathology during these years has been essential to gain our challenging results.

Comparative Study Clinical Trial
Dual electrode thalamic deep brain stimulation for the treatment of posttraumatic and multiple sclerosis tremor.
To report the results of ventralis intermedius nucleus/ventralis oralis posterior nucleus (VIM) plus ventralis oralis anterior (VOA)/ventralis oralis posterior (VOP) thalamic deep brain stimulation (DBS) for the treatment of posttraumatic and multiple sclerosis tremor. ⋯ Tremors, such as those examined in this study, that are refractory to medications and have a poor response to VIM DBS monotherapy, may respond favorably to VIM plus VOA/VOP DBS. Two electrodes may be better than one for the treatment of certain disorders; however, more study will be required to confirm this hypothesis.
