Objectives: Vertebral artery injury (VAI) during foraminal decompression in cervical spine surgery in the absence of repositioning or screw stabilization is rare. Without immediate recognition and treatment, it may have disastrous consequences. We aimed to describe the incidence and management of iatrogenic VAI in low-risk cervical spine surgery.

Despite good neurological outcome after the treatment of ruptured or incidental cerebral aneurysms, many patients complain about mood disturbances such as anxiety and depression. The present study investigated the nature of these affective disorders, their trigger factors, and corresponding structural brain changes. We assessed 63 patients matched by history of previous subarachnoid hemorrhage (SAH) and treatment modality (clipping vs.

Background: Aneurysmal subarachnoid haemorrhage (SAH) WFNS grade V is commonly known to be associated with high mortality and a very poor prognosis for survivors. Therefore, maximal invasive therapy is frequently delayed until any spontaneous improvement with or without an external ventricular drainage occurs. The aim of the study was to verify possible predictive factors and the probability of a favourable outcome in maximally treated patients.

Background: Despite the increased risk of hemorrhage and deteriorating neurological function of once-bled cerebral cavernous malformations (CM), the management of eloquently located CMs remains controversial.

Methods: All eloquently located CMs (n = 45) surgically treated between 03/2006 and 04/2011 in our department were consecutively evaluated. Eloquence was characterized according to Spetzler and Martin's definition.

Encapsulated human mesenchymal stem cells(MSC) are studied in a double transgenic mouse model of Alzheimer's disease (AD) after intraventricular implantation at 3 months of age. Abeta 40/42 deposition, and glial (GFAP) and microglial (CD11b) immunoreactivity were investigated 2 months after transplantation of either native MSC or MSC transfected with glucagon-like peptide-1 (GLP-1). CD11b immunostaining in the frontal lobes was significantly decreased in the GLP-1 MSC group compared to the untreated controls.
