Background The currently available mechanical devices fail to achieve recanalization in as many as 20–40% of proximal arterial occlusion strokes.
Background Integration of data from clinical trials and advancements in technology predict a change in selection for treatment of patients with cerebral aneurysm.
Introduction Aneurysm recurrence is a principle limitation of endovascular coiling procedures, with recurrence rates reported of >30%. The adjunct use of self-expandable stents has revolutionized the treatment of intracranial aneurysms, especially for complex morphologies, wide necks or unfavorable dome to neck ratios. However, further investigation into the durability and outcomes of stent assisted coiling procedures is required.
This report evaluated the short and midterm results of the safety and effectiveness of the treatment technique with hybrid and non-hybrid Y-configured, dual stent-assisted coil embolization of wide-neck intracranial aneurysms, and reviewed the literature concerning this technique.
BACKGROUND AND PURPOSE: Hospitals struggle to provide care for elderly patients based on Medicare payments. Amid concerns of inadequate reimbursement, we sought to evaluate the hospitalization costs for recipients of CEA and CAS placement, identify variables associated with increased costs, and compare these costs with Medicare reimbursements.
BACKGROUND AND PURPOSE: Membrane filters are EPDs, which preserve ICA flow during CAS. However, ICA flow arrest may occur with filter use. This report describes the angiographic, clinical, and histopathologic features of the filter occlusion.
BACKGROUND AND PURPOSE: Stent-like, self-expandable devices, the so-called flow diverters, are increasingly used for the treatment of wide-neck cerebral aneurysms. The immediate and short-term results are promising, but no long-term results are available. The purpose of our research was to report the long-term angiographic and cross-sectional imaging results after placement of a PED in 12 patients with wide-neck intracranial aneurysms.
BACKGROUND AND PURPOSE: Therapeutic carotid occlusion is an established technique for treatment of large and giant aneurysms of the ICA, in patients with synchronous venous filling on angiography during BTO. Concern remains that hemodynamic alterations after permanent occlusion will predispose the patient to new ischemic injury in the ipsilateral hemisphere. The purpose of this study was to assess whether BTO with synchronous venous filling is associated with normal CBF long term after carotid sacrifice.
BACKGROUND AND PURPOSE: Palpebral AVMs (pAVMs) are rare vascular lesions for which the treatment is challenging. Our aim was to present the technical aspects of the presurgical treatment by interventional neuroradiology of pAVMs and to report the clinical and angiographic results of combined (interventional neuroradiology/surgery) treatment of these malformations.
BACKGROUND AND PURPOSE: OCT has been reported as a high-resolution imaging tool for characterizing plaque in the coronary arteries. The present study aimed to evaluate the ability of OCT to visualize carotid artery plaques compared with that of IVUS in asymptomatic and symptomatic patients.
BACKGROUND AND PURPOSE: Stent-supported aneurysm coiling has been utilized with increasing frequency over the past few years, particularly for addressing treatment of complex and wide-neck aneurysms. A sizable body of literature describing various experiences with stent-supported coiling now exists. The purpose of this research was to carry out a comprehensive literature survey of stent-supported aneurysm coiling.
Objective: To review retrospectively experience with stent-assisted coiling of ophthalmic segment internal carotid artery (ICA) aneurysms to report outcome data and identify the rate of associated visual complications.
BACKGROUND AND PURPOSE: Aneurysms of the cavernous segment of the internal carotid artery generally exhibit a benign clinical course, with mass effect on cranial nerves. Rupture generally leads to carotid cavernous fistula and, rarely, to subarachnoid hemorrhage. In this study we report results of treatment in 85 patients with 86 cavernous sinus aneurysms.
Objective: Pediatric spinal arteriovenous malformations (AVMs) are rare and complex lesions to treat. There are few reports of the endovascular and microsurgical treatment of these lesions in the pediatric population, and the treatment outcomes of these patients are not well described. The aim of this study was the clinical and radiographic outcomes of spinal AVMs in pediatric patients treated via endovascular and microsurgical modalities.
BACKGROUND AND PURPOSE: Matrix coils have been developed to prevent aneurysm recanalization. Midterm anatomic results in a prospective multicenter consecutive series including patients treated with GDC or Matrix coils for ruptured aneurysms are presented.
