OBJECT The objective of this report is to describe a new approach to identify the optimal cortical target point for extracranial-intracranial (EC-IC) bypass surgery, to reliably find suitable recipient vessels for the anastomosis. METHODS Thirty consecutive patients (17 men and 13 women; mean age 54.6 +/- 11.79 years [+/- standard deviation]) with(More)
OBJECT Different revascularization procedures are used in the treatment of patients with moyamoya disease (MMD). The aim of this study was to investigate the relative contribution of direct and indirect revascularization procedures to the restoration of collateral blood supply in adult and pediatric patients with MMD. METHODS The authors performed 39(More)
Leukocyte recruitment to sites of infection or inflammation requires multiple adhesive events. Although numerous players promoting leukocyte-endothelial interactions have been characterized, functionally important endogenous inhibitors of leukocyte adhesion have not been identified. Here we describe the endothelially derived secreted molecule Del-1(More)
Even after gross tumor resection and combined radiochemotherapy, glioblastomas recur within a few months. Salvage therapy often consists of rechallenging with temozolomide in a dose-intensified schedule. Previously, low-dose metronomic temozolomide in combination with cyclo-oxigenase 2 inhibitors has had a beneficial effect as first-line treatment for(More)
OBJECT Several approaches have been established for the treatment of intracranial hypertension; however, a considerable number of patients remain unresponsive to even aggressive therapeutic strategies. Lumbar CSF drainage has been contraindicated in the setting of increased intracranial pressure (ICP) because of possible cerebral herniation. The authors of(More)
Endovascular occlusion of hemorrhagic dissecting aneurysms of the vertebral artery (VA) is not possible when the posterior inferior cerebellar artery (PICA) originates from the dissecting aneurysm or when the contralateral VA provides inadequate collateral blood flow to the distal basilar circulation. The authors introduce a VA-PICA bypass with radial(More)
There is a lack of relevant prognostic and predictive factors in neurooncology besides mutation of isocitrate dehydrogenase 1, codeletion of 1p/19q and promoter hypermethylation of O (6) -methylguanine-DNA-methyltransferase. More importantly, there is limited translation of these factors into clinical practice. The cancer genome atlas data and also clinical(More)
During the metastatic process tumor cells circulate in the blood stream and are carried to various organs. In order to spread to different organs tumor cell-endothelial cell interactions are crucial for extravasation mechanisms. It remains unclear if tumor cell dissemination to the spinal bone occurs by passive entrapment of circulating tumor cells or by(More)
BACKGROUND AND PURPOSE Occlusive cerebrovascular moyamoya disease (MMD) is rare and has been characterized mainly in Asian countries, so far. In recent years, MMD has been increasingly reported worldwide, raising the question whether its clinical presentation would vary amongst different ethnic backgrounds. Here, a homogeneous series of 153 patients with(More)
In patients with complex intracranial aneurysms or skull base tumors, parent vessel occlusion and flow replacement by high-flow bypass surgery is a demanding therapy, both for the neurosurgeon and the neuroanesthesiologist. One reason for this is the need for prolonged temporary occlusion of a major cerebral artery, which carries a high risk of(More)
