Review Case Reports Historical ArticlePituitary apoplexy: an overview of 186 cases published during the last century.
Pituitary apoplexy is a rare and life-threatening complication occurring in 0.6-10.5% of all cases of pituitary adenomas. Although the association between pituitary apoplexy and visual dysfunction has been recognized for a long time, the optimal management of this problem still remains controversial. The purpose of this overview was to present the surgical experience by analyzing the literature on the management of pituitary apoplexy for better treatment of these cases. ⋯ Based on an overview of 186 cases of apoplectic pituitary adenoma presenting with monocular or binocular blindness, we highlight the importance of correct diagnosis and an early, but not necessarily emergency, surgery within the first week of admission to optimize visual outcome of such patients. The illustrative case further exemplifies the value of close interaction between members of the management team for optimal outcome.

Pedicle screw-based dynamic stabilization of the thoracolumbar spine with the Cosmic-system: a prospective observation.
The objective of the study was to generate prospective data to assess the clinical results after dynamic stabilization with the Cosmic system (Ulrich Medical). ⋯ Dynamic stabilization with Cosmic achieved significant improvement of pain, related disability, mental/physical health, and mobility, respectively, and a high rate of satisfied patients. A reoperation rate of 10% during follow-up seems relatively high at first glance. Comparable data, however, are scarce, and a prospective randomized trial (spondylodesis vs. dynamic stabilization) is warranted based on these results.

Image-guided surgical planning using anatomical landmarks in the retrosigmoid approach.
The suboccipital lateral or retrosigmoid approach is the main neurosurgical approach to the cerebellopontine angle (CPA). It is mainly used in the treatment of CPA tumors and vascular decompression of cranial nerves. A prospective study using navigation registered with anatomical landmarks in order to identify the transverse and sigmoid sinuses junction (TSSJ) was carried out in a series of 30 retrosigmoid craniotomies. The goal of this study was to determine the accuracy of this navigation technique and to establish the relationship between the location of the asterion and the TSSJ. ⋯ Navigation using anatomical landmarks for registration is a reliable method in the localization of the TSSJ for retrosigmoid craniotomies and thereby avoiding unnecessary sinus exposure. In addition, the method proved to be fast and accurate. The asterion was found to be a less accurate landmark for the localization of the TSSJ using navigation.

Case ReportsNatura abhorret a vacuo--use of fibrin glue as a filler and sealant in neurosurgical "dead spaces". Technical note.
The objective of this study is to report our experience and illustrate our technique in the use of fibrin glue in the treatment of post-operatory cerebrospinal fluid (CSF) leaks and collections following different neurosurgical procedures. ⋯ In our experience, the injection of fibrin glue has proved to be effective in filling or sealing post-operative "dead spaces" and treating minor or initial CSF leaks resulting from procedures of transsphenoidal, cranial and spinal surgery, adding another possibility in the management of many of these dreadful complications.

Circulatory arrest and deep hypothermia for the treatment of complex intracranial aneurysms--results from a single European center.
Vascular neurosurgery faces the controversial discussion about the need for deep hypothermia and circulatory arrest (dh/ca) for the treatment of complex cerebral aneurysms. In this retrospective analysis, we present our experience in the treatment of 26 giant and large cerebral aneurysms under profound hypothermia and circulatory arrest. ⋯ We observed neurological deterioration immediately postoperatively in 13 patients, but all patients fully recovered within 6 months except for four patients. A long cardiac arrest time reflected complex pathoanatomical conditions. We conclude that the clipping procedure under deep hypothermia and circulatory arrest remains a pivotal armament in complex vascular neurosurgery.
