BACKGROUND AND PURPOSE A number of flow-diverting devices have become available for endovascular occlusion of cerebral aneurysms. This article reports immediate and midterm results in treating unruptured aneurysms with the PED. MATERIALS AND METHODS A prospective registry was established at 3 Australian neurointerventional units. Aneurysms were treated on the basis of unfavorable anatomy or r...

afford this method of treatment. The lack of available endovascular expertise in many state and academic hospitals is related in part to the high costs related to these cases, but also to a lack of neurointerventional expertise within many academic and state institutions. Neither interventional radiology nor neurointervention is recognised locally as a subspeciality despite the availability of ...

Although liquid adhesives or glue have been used as embolic agents for nearly three decades, experience with them outside of neurointerventional indications is generally limited. Cyanoacrylates are the main liquid adhesives used in the vascular system and have an important role in managing vascular abnormalities, especially arteriovenous malformations. Vascular occlusion results as these agents...

Over a 31-month period, we performed four neurointerventional procedures after which unexpected foreign bodies were noted in multiple arteries. All four procedures had in common the use of Fastracker-18 infusion microcatheters. Histologically, the intravascular debris looked strikingly similar to the hydrophilic coating on the catheter. An in vitro test mimicking clinical use of the microcathet...

BACKGROUND AND PURPOSE Advances in thrombolytic therapy, brain imaging, and neurointerventional techniques provide new therapeutic options for acute stroke. Intra-arterial thrombolysis has proved to be a potent therapeutic tool. To show that this procedure can be performed in community hospitals, we describe our experience with a group of 11 patients treated for middle cerebral artery occlusion...

BACKGROUND AND PURPOSE Recent neurointerventional and neurosurgical technologies require an understanding of lesions and adjacent structures in three dimensions. To clarify the clinical benefits of rotational 3D digital subtraction angiography (DSA), we retrospectively analyzed its advantages and disadvantages at the time of interventional procedures for ruptured cerebral aneurysms. METHODS F...

Intracranial atherosclerosis accounts for 5 to 10% of all strokes. The natural history is poor, especially among patients with a greater than 70% stenosis. Studies of medical therapy have shown no benefit to warfarin over aspirin in these patients. In fact, patients with a greater than 70% stenosis who present with a stroke in the territory at risk have a 25% risk of stroke in the subsequent 24...

This is the first in a set of documents intended to standardize techniques, procedures, and practices in the field of endovascular surgical neuroradiology. Standards are meant to define core practices for peer review, comparison, and improvement. Standards and guidelines also form the basic dialogue, reporting, and recommendations for ongoing practices and future development.

BACKGROUND AND PURPOSE Antiplatelet therapy is associated with decreased ischemic events after neurointerventional procedures. Antiplatelet resistance negates the protective effects of antiplatelet medication, leading to a higher incidence of ischemic events. A possible link between antiplatelet hyper-response and increased hemorrhagic complications has been inadequately investigated. We aimed ...

The use of certain large-caliber (ie, 7F to 9F) coronary guiding catheters for selected neuroendovascular procedures is described in the context of surveying recently developed neurovascular guiding catheters. These large-caliber guiding catheters have proved useful in situations requiring proximal access to tortuous brachiocephalic arteries, permitting coaxial delivery of relatively large neur...
