BACKGROUND AND PURPOSE ISRs remain a major issue in the endovascular management of ICAD, requiring retreatment by reangioplasty. The aim of the present study was to evaluate the technical feasibility, safety, and efficiency of the novel DEBs for neurovascular ISRs. MATERIALS AND METHODS Fifty-one patients (median age, 67 years; age range, 34-82 years;(More)
We evaluated the coronary balloon-expandable cobalt chromium stent Coroflex Blue for the treatment of intracranial atherosclerotic arterial stenoses (IAAS). Between March 2007 and October 2007, a total of 25 patients (20 male, age median 67 years) with 30 IAAS underwent endovascular treatment using Coroflex Blue stents (B. Braun, Germany). Location and(More)
BACKGROUND Balloon dilatation and deployment of a self-expanding stent is a safe treatment for intracranial atherosclerotic stenoses. The significant recurrence rate might be related to the high radial force of the Wingspan stent. OBJECTIVE To evaluate the procedural safety and stenosis recurrence rate by the use of a stent with reduced radial force(More)
BACKGROUND AND PURPOSE Recent studies on stent placement of significant stenoses at the origin of the vertebral artery reported excellent immediate results. Long-term outcomes, however, were disappointing due to high restenosis rates and stent breakage. In the present study, we evaluated the application of a short drug-eluting balloon-expandable coronary(More)
Intracranial arterial stenosis is a frequent cause of major stroke [1]. Medical treatment with either platelet antiaggregation or anticoagulation may be an option for asymptomatic patients and for those not suitable for endovascular therapy. In patients with high-grade symptomatic stenoses, balloon dilatation using coronary stents [2], neurovascular(More)
Stenting in intracranial atherosclerotic disease (ICAD) is increasingly debated, due to issues of procedural safety, technical efficacy, and in-stent recurrent stenoses (ISR). In the present study, feasibility, safety, and efficacy of angioplasty using a drug-eluting balloon (DEB) followed by the implantation of a self-expanding stent (Enterprise) were(More)
INTRODUCTION With the widespread use of carotid artery stenting, previously unknown technical mistakes of this treatment modality are now being encountered. There are multiple strategies for the treatment of in-stent restenosis. With regard to surgical management, endarterectomy and patch plasty are favored. To the best of our knowledge, this report is the(More)
Advances in medical devices technology now allow the endovascular treatment of stenotic lesions of the intracranial arteries with the help of the implantation of microstents. The technical development in stent, catheter and guidewire technology now allows the application of these devices in the intracranial arteries, where access issues due to difficult(More)
