Retrograde suction decompression assisted clipping of large and giant cerebral aneurysms: our experience.
The aim of this study was to present our experience with retrograde suction decompression in clipping of large and giant cerebral aneurysms and analyze its advantages and pitfalls. ⋯ Retrograde suction decompression is a successful adjunct to clipping of large and giant cerebral aneurysms.

A laparoscopic approach to ventriculoperitoneal shunt placement with a novel fixation method for distal shunt catheter in the treatment of hydrocephalus.
The laparoscopically assisted ventriculoperitoneal (VP) shunt has been widely used in the clinical treatment of hydrocephalus for its simplicity and reliability. Despite significant improvements in shunt procedures, shunt complications remain common. Our clinical experiences suggest that the fixation of the distal (peritoneal) shunt catheter using threads and hemoclips may partially contribute to complications of the distal shunt including obstruction of the shunt and infection. In this study, we explored a novel fixation method in the laparoscopically assisted VP shunt with use of the liver falciform ligament as a natural support for fixation of the distal shunt catheter. ⋯ The modified laparoscopically assisted VP shunt in the treatment of hydrocephalus with fixation of the distal shunt catheter to a natural anatomic structure could potentially reduce the necessity of repeat surgery for addressing the complications caused by catheter obstruction and infections, reduce the chance of adhesions, and would be of benefit to those patients who need future revisions.

X-knife stereotactic radiosurgery on the trigeminal ganglion to treat trigeminal neuralgia: a preliminary study.
Stereotactic radiosurgery is an attractive option for elderly patients and those who do not tolerate the more invasive surgical procedures available for trigeminal neuralgia (TN). In the majority of the studies, the target location was designated as the proximal nerve at the root entry zone (REZ). The purpose of this article was to evaluate the efficacy of and complications associated with X-knife stereotactic radiosurgery on the trigeminal ganglion (TG) for TN. ⋯ Similar to other TN radiosurgery reports, X-knife stereotactic radiosurgery for TN provides effective pain relief with a low complication rate.

We present our experience using a standardized transnasal transclival approach (TTA) for endoscopic removal of chordomas of the clivus. ⋯ The TTA provides an elegant alternative to classical approaches to clival lesions especially for midline tumor locations. For large tumors iMRI is of significant help. Dural reconstruction of large defects emerged as the greatest challenge of this technique even for experienced endoscopic surgeons.

Comparative StudyClinical outcomes and quality of life 1 year after open microsurgical decompression or implantation of an interspinous stand-alone spacer.
Interspinous stand-alone implants are inserted without open decompression to treat symptomatic lumbar spinal stenosis (LSS). The insertion procedure is technically simple, low-risk, and quick. However, the question remains whether the resulting clinical outcomes compare with those of microsurgical decompression, the gold standard. ⋯ Implantation of an interspinous stand-alone spacer yields clinical success comparable to open decompression, at least within the first year of FU. The 1-year conversion rate of 27.3% is, however, decidedly too high.
