<h3>BACKGROUND AND PURPOSE:</h3> Endoluminal reconstruction with flow diverting devices represents a novel constructive technique for the treatment of cerebral aneurysms. We present results first prospective multicenter trial flow-diverting construct intracranial <h3>MATERIALS METHODS:</h3> Patients unruptured aneurysms that were wide-necked (>4 mm), had unfavorable dome/neck ratios (<1.5), or failed previous therapy enrolled in PITA between January and May 2007 at 4 (3 European 1...
<h3>BACKGROUND AND PURPOSE:</h3> FD technology enables reconstructive repair of otherwise difficult-to-treat intracranial aneurysms. These stentlike devices may induce progressive aneurysm thrombosis without additional implants and initiate complete reverse vessel remodeling. The associated vascular biologic processes are as yet only partially understood. <h3>MATERIALS METHODS:</h3> From 12 different centers, 13 cases delayed postprocedural rupture were recorded analyzed. Symptom, location...
We endeavored to develop an unruptured intracranial aneurysm (UIA) treatment score (UIATS) model that includes and quantifies key factors involved in clinical decision-making the management of UIAs assess agreement for this among specialists UIA research.
Clazosentan, an endothelin receptor antagonist, has been shown to reduce vasospasm after aneurysmal subarachnoid hemorrhage (aSAH). CONSCIOUS-3 assessed whether clazosentan reduced vasospasm-related morbidity and all-cause mortality postaSAH secured by endovascular coiling.This double-blind, placebo-controlled, phase III trial randomized patients with aSAH coiling ≤ 14 days intravenous (5 or 15 mg/h) placebo. The primary composite end point (all-cause mortality; new cerebral infarcts delayed...
<b>BACKGROUND AND PURPOSE:</b> Endovascular therapy of intracranial arteriovenous malformations (AVMs) is increasingly used. However, it still under discussion which embolic material optimal. We report our experience in the treatment AVMs with ethylene-vinyl alcohol copolymer (Onyx). <b>MATERIALS METHODS:</b> Between July 2002 and January 2008, brain were embolized Onyx 82 consecutive patients department. There 41 females males a mean age 44.2 years (range, 15–85 years). Clinical...
Background and Purpose— The introduction of flow diverters (FDs) has expanded the possibilities for reconstructive treatment difficult intracranial aneurysms. Concern remains as to long-term patency perforating arteries side branches covered during stent placement. Our purpose was evaluate performance early effect on after implantation Silk FD in basilar artery Methods— Twelve patients with an aneurysm that treated by were included our retrospective study. Both unruptured previously...
Higher magnetic field strengths and continuous improvement of high-resolution imaging in multiple sclerosis (MS) are expected to provide unique in-vivo non-invasive insights pathogenesis clinical monitoring. The purpose this study was investigate the potential MS lesions vivo comparing 7T with conventional 1.5T.Twelve consecutive patients clinically definite were scanned on a whole-body scanner 1.5T Avanto. protocol consisted axial proton density (PD) + T2-weighted turbo spin-echo...
To investigate the role of prophylactic cranial irradiation (PCI) within a trimodality protocol (chemotherapy, chemoradiotherapy, surgery) for patients with operable stage IIIA non-small-cell lung cancer (NSCLC).After mediastinoscopic staging, NSCLC were enrolled to German multicenter trial and randomly assigned receive either primary resection followed by adjuvant thoracic radiation therapy (50 60 Gy; arm A) or preoperative chemotherapy (cisplatin/etoposide [PE]; three cycles) concurrent...
Ruptured aneurysms of < 2 mm are not amenable to endovascular coiling and therefore pose a significant treatment challenge.To test recently introduced flow diverters that allow reconstruction via another method may represent new option for such lesions.Three female patients presented with acute subarachnoid hemorrhage. An aneurysm was identified in all as the cause bleeding. The were located at C2 segment internal carotid on basilar bifurcation other. All had failed early attempts. Flow...
Background and Purpose— To address the increasing need to counsel patients about treatment indications for unruptured intracranial aneurysms (UIA), we endeavored develop a consensus on assessment of UIAs among group specialists from diverse fields involved in research UIAs. Methods— After composition group, Delphi was initiated identify rate all features, which may be relevant assess their by using ranking scales analysis inter-rater agreement (IRA) each factor. IRA categorized as very high,...
High blood pressure is one of the main risk factors for cerebral white matter lesions (WMLs). There limited evidence from randomized trial that pressure-lowering able to slow WML progression. We investigated whether telmisartan prevents progression in imaging substudy Prevention Regimen Effectively Avoiding Second Strokes (PRoFESS) trial.This predefined comprised 771 patients (mean age, 65 years) with recent ischemic stroke noncardioembolic origin who received or placebo during a mean...
✓ The authors present two cases of patients with small, acutely ruptured, wide-necked aneurysms the distal vertebral artery that were not amenable to conventional coil embolization and instead treated by means a double-stent method in which one stent was placed inside another. Angiography performed immediately after procedure revealed significant reduction aneurysm filling; total occlusion lesion observed 7 days confirmed 6 months later both aneurysms. By placing other, permeability can be...
