BACKGROUND Brain arteriovenous malformations (BAVMs) are a rare but important cause of hemorrhagic stroke in young adults. Functional polymorphisms in proinflammatory cytokines have been associated with various cerebrovascular phenotypes, including ischemic stroke, aneurysmal subarachnoid hemorrhage, and BAVM. OBJECTIVE To investigate whether functional(More)
BACKGROUND AND PURPOSE Flow diversion is a new strategy for the treatment of complex paraclinoid aneurysms. However, flow diverters have, to date, not been tested in direct comparison with other available treatments. We present a matched-pair comparison of paraclinoid aneurysms treated with the PED versus other endovascular techniques. MATERIALS AND(More)
Glioblastoma Multiforme, the most common and aggressive primary brain tumor, remains incurable despite of the advent of modern surgical and medical treatments. This poor prognosis depends by the recurrence after surgery and intrinsic or acquired resistance to chemotherapy and radiotherapy. Nitric oxide is a small molecule that plays a key roles in glioma(More)
SUMMARY Angiographic recurrence following endovascular therapy is an indirect measure of the potential for hemorrhage. Because patients and physicians consider recurrence to be a suboptimal outcome with some chance of future hemorrhage, much effort has been expended to reduce the incidence of recurrence. The literature regarding aneurysm recurrence(More)
BACKGROUND AND PURPOSE Patients with aneurysmal subarachnoid hemorrhage are typically kept in the intensive care unit to be monitored for signs of delayed cerebral ischemia (DCI). Identifying patients at lower risk for DCI could have a positive financial impact by allowing earlier transfer from the intensive care unit. METHODS We analyzed 307 consecutive(More)
BACKGROUND Flow diversion represents a major paradigm shift in the treatment of unruptured intracranial aneurysms. The potential impact of this technique on coil utilization and adjunctive techniques such as balloon-assisted and stent-assisted coiling is unknown. In this study, the effect of introduction of flow diversion devices on the utilization of coil(More)
Knowledge of spinal cord arteriovenous malformations (AVMs) has recently been improved by studies on pathophysiology, neuroimaging, and genetic data. Nevertheless, the natural history of these lesions remains poorly understood. The authors present the case of an angiographic regression of a nidal-type spinal AVM at T-12 to L-1 in a 46-year-old woman with no(More)
OBJECTIVE The worldwide population aging and the nowadays medical advances impose to consider new management guidelines for elderly. Aim of this study was to assess the best treatment in elderly with multiple intracranial aneurysms (MIA). METHODS From 1994 to 2011, we admitted 1462 patients with ruptured cerebral aneurysm. Among those aged ≥65 years, 43(More)
Flow-diverters are used in the treatment of large and complex intracranial aneurysms. One major concern with this concept is the potential for compromise of side branches and perforators covered by the device. We describe three patients treated with the Pipeline embolization device (PED; ev3 Endovascular, Plymouth, MN, USA) who developed immediate(More)
