Covered stent implantation for the treatment of intracranial arterial disorders / 介入放射学杂志

ABSTRACT

The coronary covered stents have been more and more used to treat intracranial arterial diseases for recent years,and the hot point in study has gradually changed from clinical application of coronary covered stents to the fundamental and clinical trial of specially-designed intracranial covered stentsThe covered stents are mainly employed for the treatment of intracranial arterial disorders,including giant,wide-necked or minute cerebral aneurysms,intracranial pseudoaneurysms caused by a variety of reasons,fusiform or dissecting aneurysms of vertebral-basic artery,and internal carotid cavernous fistula,etc.It is very difficult for current surgical or endovascular treatment,both materially and technically,to deal with the above mentioned intracranial disorders.The covered stent can restore the anatomic shape of artery by direct sealing the aneurysmal neck and the fistula.The complications of covered stent treatment include defect of cranial nerves,occlusion of parent artery or branches.This article aims to review the related medical literature published both at home and abroad,to make a retrospective analysis of the therapeutic results,and to put forward some issues of common interest.
