BACKGROUND: There is limited knowledge about associated rates, aneurysm characteristics, technical factors, and immediate impact of unsuccessful placement of the lead (first) coil during endovascular embolization of intracranial aneurysms. OBJECTIVE: To determine the rates, associated risk factors, and consequences of lead coil placement failure in consecutive embolization procedures.
Background: In patients with ischemic stroke, endovascular treatment results in a higher rate of recanalization of the affected cerebral artery than systemic intravenous thrombolytic therapy. However, comparison of the clinical efficacy of the two approaches is needed.
Background Endovascular treatment of intracranial aneurysms relies on coaxial catheter support systems to provide safe and stable access. Large-bore distal intracranial catheters have become necessary for aneurysm treatment with flow diverting devices including the Pipeline embolization device (PED). These catheters must accommodate 0.027 inch microcatheters, be supple enough to track distally and be able to provide sufficient support for manipulations required for PED deployment.
Background and Purpose—Therapeutic hypothermia improves clinical outcome after cardiac arrest and appears beneficial in other cerebrovascular diseases. We conducted this study to investigate the relationship between surface head/neck cooling and brain temperature.
Background and Purpose—This study aimed at evaluating whether ultrasound monitoring of moderate asymptomatic carotid stenosis may help in identifying subjects at high risk for vascular events.
Objectives To investigate long-term mortality and cause of death after acute stroke in adults aged 18 through 50 years and to compare this with nationwide age- and sex-matched mortality rates.
Background: Endovascular mechanical revascularization (thrombectomy) is an increasingly used method for intracranial large vessel recanalization in acute stroke. The purpose of the study was to analyze the recanalization rate, clinical outcome, and complication rate in our stroke patients treated with mechanical revascularization.
Purpose: Percutaneous vertebroplasty with polymethylmethacrylate (PMMA) is used increasingly for pain relief in symptomatic neoplastic or osteoporotic compression fractures. However, restoration of the stiffness of the treated vertebrae might propagate secondary fracture of adjacent vertebrae. Elastoplasty might prevent these secondary fractures. We assessed retrospectively our experience with elastoplasty in 12 patients, focusing on silicone migration.
Background—Fixed-dose unmonitored treatment with dabigatran etexilate is effective and has a favorable safety profile in the prevention of stroke in atrial fibrillation patients compared with warfarin. We hypothesized that genetic variants could contribute to interindividual variability in blood concentrations of the active metabolite of dabigatran etexilate and influence the safety and efficacy of dabigatran.
Introduction: Since the flow diverters (FDs) have been introduced it is possible to treat aneurysms that are considered difficult or impossible to treat with usual endovascular or surgical methods. It is still uncertain which aneurysms are suitable for this new treatment. We present the periprocedural complications, immediate result, late complications, imaging follow-up at 6 and 12 months and clinical follow-up at 2–23 months.
Objectives: Carotid angioplasty with stenting (CAS) in patients with carotid stenosis (CS) has become more restricted in France especially since the disclosure of such studies as EVA-3S and Stent-supported percutaneous angioplasty of the carotid artery versus endarterectomy (SPACE). This report is of a series of CS cases contraindicated for endarterectomy that underwent CAS at a French center of interventional neuroradiology.
Objective: Perioperative stroke and death (PSD) are more common after carotid artery stenting (CAS) than after carotid endarterectomy (CEA) in symptomatic patients, but whether this is also true in asymptomatic patients is unclear. Furthermore, use of both CEA and CAS varies geographically, suggesting possible variation in outcomes. We compared odds of PSD after CAS and CEA in asymptomatic patients to determine the impact of this variation.
Background and Purpose—Flow diverters are important tools in the treatment of intracranial aneurysms. However, their impact on aneurysmal occlusion rates, morbidity, mortality, and complication rates is not fully examined.
Objective: Among patients with symptomatic carotid artery stenosis, carotid artery stenting (CAS) is associated with a higher risk of periprocedural stroke or death than carotid endarterectomy (CEA). Uncertainty remains whether the balance of risk changes with time since the most recent ischemic event.
Introduction: Our purpose was to analyze the long-term evolution of wide neck cerebral aneurysms treated with stent assistance.
