BACKGROUND AND PURPOSE: VB artery stenosis is associated with a high risk of recurrent ischemic events, and knowledge about the hemodynamic relevance of VB stenosis is important for clinical decision making. In this study, multiple inflow pulsed ASL MR imaging was assessed for its ability to measure CBF and ATT in patients with VB disease.
BACKGROUND: Technological advances have resulted in diminishing perioperative complications reported during carotid artery stenting (CAS) trials. Because trial experience lags behind technological advances, an understanding of the incidence of perioperative complications after CAS remains in flux.
Background and Purpose—National registration studies (the Japanese Registry of Neuroendovascular Therapy [JR-NET] and JR-NET2) have determined the current status and outcomes of neuroendovascular therapy (neuro-EVT). We analyzed short-term outcomes of EVT for asymptomatic unruptured intracranial aneurysms (UIAs).
Background and Purpose—Mechanical thrombectomy using stent retriever devices have been advocated to increase revascularization in intracranial vessel occlusion. We present the results of a large prospective study on the use of the Solitaire Flow Restoration in patients with acute ischemic stroke.
Background and Purpose—Depression after stroke has been associated with increased mortality, but little is known about this association among very old people.
Background and Purpose—Previous economic studies outside Australia have demonstrated that patients treated with tissue-type plasminogen activator (tPA) within 4.5 hours of stroke onset have lower healthcare costs than those not. We aim to perform cost-effectiveness analysis of intravenous tPA in an Australian setting.
BACKGROUND AND PURPOSE: Flow-diverting devices now offer a new treatment alternative for cerebral aneurysms. We present the results of a large single-center series of patients treated with the PED, including long-term follow-up.
Background and Purpose—Recanalization status after intravenous thrombolysis (IVT) in patients with ischemic stroke is a reference point to proceed with a rescue reperfusion intervention, although early neurological improvement (NI) may preclude endovascular procedures. We aimed to evaluate the importance of restoration of blood flow at the arterial occlusion site in subgroups of patients with stroke stratified by early NI after IVT.
BACKGROUND AND PURPOSE: Paraclinoid aneurysms represent challenging lesions for which endovascular techniques have gained widespread application in their treatment. A new endovascular strategy, flow diversion, is gaining importance in the treatment of these aneurysms. Before embracing flow diversion in larger numbers of patients with paraclinoid aneurysms, it is important to know the safety and efficacy of “traditional” endovascular methods for these aneurysms. We review complications and outcomes of patients with unruptured paraclinoid aneurysms treated with coils, with or without balloon and stent assistance, over the past 12 years at our institution.
BACKGROUND: Seizures are a common presenting symptom of arteriovenous malformations (AVMs). However, the impact of treatment modality on seizure control remains unclear.
BACKGROUND AND PURPOSE: Whether to treat UIAs is controversial. The aim of the study was to compare the clinical outcome of patients with UIAs who were either treated conservatively or preventively.
Background and Purpose—Knowledge of the long-term excess mortality in pediatric aneurysm patients is lacking. The aim of this study was to assess the long-term excess mortality of 102 pediatric patients with cerebral aneurysm treated at the department of neurosurgery at Helsinki University Central Hospital between 1937 and 2009.
BACKGROUND: Cardiac dysfunction is a well-known complication of aneurysmal subarachnoid hemorrhage (aSAH). However, the clinical significance of cardiac complications is largely unknown.
SUMMARY: POC testing is defined as diagnostic testing at or near the site of patient care. Rapid measurement of the intensity of anticoagulation and, more recently, platelet inhibition allows dose titration of adjuvant medications such a heparin and antiplatelet agents during neuroendovascular procedures. However, knowledge among practicing physicians regarding the pathophysiologic basis of these measurements and variations in knowledge about the differences among devices is often limited. This review discusses the role of anticoagulation in endovascular procedures and the currently available POC tests for anticoagulation monitoring.
Background and Purpose—The ideal timing of coiling or clipping after aneurysmal subarachnoid hemorrhage is unknown. Within the International Subarachnoid Aneurysm Trial we assessed differences in incidence of delayed cerebral ischemia and clinical outcome between different timings of treatment.
