ReviewSurgical anatomy of the sacral hiatus for caudal access to the spinal canal.
The sacral hiatus is used for access to the spinal canal in many neurosurgical and anesthesiologic procedures. The aim of the present paper is to give a review of its anatomical characteristics relevant to permit correct and uncomplicated accesses. ⋯ The mean sacral space depth has been observed to be 4.6 mm in adults and 3.5 mm in infants. On the basis of anatomical measurements of the sacral hiatus, lower insertion angles have been suggested in infant with respect to adult subjects (21° vs. 58°).

Review Historical ArticleA clinical review of cerebral vasospasm and delayed ischaemia following aneurysm rupture.
The continuation of a review of delayed vasospasm after aneurysmal subarachnoid haemorrhage, originally published in 1994 and partially updated at the ninth vasospasm conference in Turkey, is presented. Further online and physical searches have been made of the relevant literature. The incidence of delayed ischaemic deficit (DID) or symptomatic vasospasm reported in 1994 was 32.5% in over 30,000 reported cases. ⋯ It thus appears likely that delayed vasospasm is still common but less so, and that the overall outcome has improved. This may be due to the more widespread use of calcium antagonists and more effective fluid management. A number of other mechanical and drug treatments are also mentioned.

Case ReportsInformation-guided surgical management of gliomas using low-field-strength intraoperative MRI.
Contemporary technological developments revolutionized management of brain tumors. The experience with information-guided surgery of gliomas, based on the integration of the various intraoperative anatomical, functional, and histological data, is reported. ⋯ Information-guided management of gliomas using low-field-strength ioMRI provides a good opportunity for maximal possible tumor resection, and may result in survival advantage, particularly in patients with WHO grade III neoplasms.

Comparative StudyDecompressive hemi-craniectomy is not necessary to rescue supratentorial hypertensive intracerebral hemorrhage patients: consecutive single-center experience.
A consensus on decompressive surgery for hypertensive intracranial hemorrhage (ICH) has not been reached. We retrospectively analyzed our single-center experience with ICH. ⋯ Decompressive craniectomy is not necessary for rescue in ICH if the hematoma can be removed completely.

Multicenter StudyPercutaneous surgical treatment in lumbar spinal stenosis with Aperius-PercLID: indications, surgical technique and results.
Interspinous spacers have recently been used in the treatment of lumbar spinal stenosis. In vitro studies have demonstrated a reduction in facet joint forces by 68% and annulus pressures by 63%. MRI studies have demonstrated increased canal and neural foraminal area after implantation of these devices. ⋯ The average VAS pain score improved from 8.2 to 3.6 (scale of 1 to 10). The overall patient satisfaction rate was 76%. No complications were detected at 6 months' follow-up.
