To determine whether preoperative chronic kidney disease (CKD) is associated with inferior perioperative outcomes in patients undergoing lumbar arthrodesis. ⋯ Our study suggests that patients with CKD may be more likely to develop perioperative complications after lumbar arthrodesis. Future studies are necessary to corroborate our findings.

Case Reports
Risks of endoscopic temporal ventriculocisternostomy for isolated lateral ventricle: Anatomical surgical nuances.
Entrapment of the temporal horn, known as isolated lateral ventricle (ILV), is a rare type of noncommunicating focal hydrocephalus, and standard treatment has not been established. We report 2 cases of endoscopic surgery for ILV and highlight the anatomic surgical nuances to avoid associated surgical risks. ⋯ Although endoscopic temporal ventriculocisternostomy is considered a safe and less invasive procedure for treatment of symptomatic ILV, the technique is still associated with risks. To avoid complications, it is necessary to be familiar with the anatomy of the choroidal arteries and the pertinent endoscopic intraventricular orientation. Additionally, sufficient experience is required before it can be recommended as the treatment of choice.

No true reference values for intracranial pressure (ICP) in humans exist; current values are estimated from measurements in adults who undergo treatment in order to correct ICP. We report ICP values in a "pseudonormal" group of children and adults to examine if age affects ICP. ⋯ We found similar differences in daytime and nighttime ICP between children and adults with no ICP-related disease. ICP seems to decrease with age across all ages. This has implications for therapeutic interventions (e.g., shunt valve selection or resistance in external ventricular drainage).

We aimed to determine the long-term effects of Gamma knife radiosurgery (GKS) on remnants in the cavernous sinus (CS) after transsphenoidal surgery (TSS) for acromegaly and to identify its possible adverse effects. ⋯ GKS is an effective adjuvant treatment option for remnant tumors inside the CS after TSS. Maximal surgical resection, leaving minimal volume of remnants only inside the CS, allows the safe and sufficient delivery of a radiation dose to tumors, thereby increasing the possibility of remission. However, the risk of new hypopituitarism and radiation necrosis should be considered when tumors inside the CS are treated with GKS.

Comparative Study
Posterior Cervical Laminectomy Results in Better Radiographic Decompression of Spinal Cord Compared to Anterior Cervical Discectomy and Fusion.
Cervical spondylitic myelopathy is a degenerative condition resulting from chronic spinal cord compression and a leading cause of nontraumatic spinal cord dysfunction. The chief surgical goal in the management of cervical spondylitic myelopathy is adequate spinal cord decompression with or without fusion to slow or prevent further neurologic decline. We conducted a radiographic analysis of canal parameters preoperatively and postoperatively for patients undergoing either anterior or posterior cervical decompression. ⋯ In this quantitative radiographic study, we found that although both posterior cervical laminectomy and anterior cervical discectomy yielded significant decompression, laminectomy yielded a greater degree of decompression of the posterior CSF space.
