Objective: Current numbers on demographic information from Austria as well as population projections for 2017-2080 were obtained from Statistics Austria (STAT). To provide reasonable lower and upper bounds for the projections, three scenarios were used: a lower/main/upper scenario reflecting[for full text, please go to the a.m. URL], 69.

Objective: Standardized treatment algorithms for recurrent glioblastoma multiforme (rGBM) are still lacking. The neurosurgical armamentarium for circumscribed rGBMs comprises resection and stereotactic brachytherapy (SBT) as possible local treatment concepts.

Objective: Aneurysms of the middle cerebral artery are primarily considered to be treated by surgical clipping due to easy surgical exposure. The main advantage of aneurysm clipping is its potential ability to occlude aneurysms totally and permanently.

Background: An intimate knowledge of the so called first order anastomotic veins of the supratentorial cerebral drainage is of crucial importance for exact planning of microneurosurgical procedure, for implantation of grid electrodes in epilepsy surgery and for decompressive craniectomies.

OBJECTIVE: A spinal perimedullary arteriovenous fistula (PMAVF) is a direct fistula of one or more spinal arteries into the perimedullary venous network with reversed venous flow and subsequent venous congestion of the spinal cord. The therapeutic goal of surgery is to normalize the venous drainage by obliterating the fistula. Strictly ventral lesions typically require an anterior approach to ensure adequate exposure of the fistula as well and the preservation of the physiological blood supply to the spinal cord. CLINICAL PRESENTATION: We present a case of a ventral PMAVF at the level of T10 with feeders from the anterior spinal artery, caudally draining veins on the ventral spinal cord, and a dilated transmedullary vein filling cranially draining veins on the dorsal aspect of the spinal cord. TECHNIQUE: The dilated transmedullary vein was approached by a laminectomy. The vein was coagulated, and the gliotic channel was used to approach the ventral fistula site from the dorsal surface of the spinal cord. Complete obliteration of the fistula was achieved, and the preoperative neurological deficit improved. CONCLUSION: We conclude that transmedullarly draining veins offers a possible dorsal approach for the occlusion of some ventral PMAVFs, thus avoiding more complex anterior approaches to the ventral spinal cord.

Objective: The correct and safe multisegmental posterior cervical stabilization is still challenging. Main risks are screw dislocations and secondary instability, distortion of the alignment of the cervical spine and the intraoperative damage to neural and vascular structures.

Prognosis after subarachnoid haemorrhage secondary to a ruptured intracranial aneurysm is greatly influenced by arterial vasospasm. In 50 patients the influence of the amount of subarachnoid blood detected by CT and the amount of the nonionic contrast medium on the postoperative vasospasm and the outcome of the patient were investigated. For angiographically proven vasospasm, a grading system is suggested. There was a good correlation between the extent of the haemorrhage and the development of cerebral vasospasm. If used within limits, the volume of the contrast medium does not seem to exercise any influence on the development of vasospasm and on the results after treatment. Therefore, a complete investigation of the cerebral vascular system should be performed before surgical management of the ruptured cerebral aneurysm is initiated.
