Technique and Clinical Results of Carotid Stenting under Distal Protection

Abstract

We perfomed carotid artery stenting(CAS) in 215 patients from August 1997 to October 2003 mainly using the distal protection technique. Our technique and clinical results are described in this paper.

Angiographic findings: A) Left common carotid angiogram (oblique view). The left internal carotid artery was faintly opacified but the distal portion was not identified in arterial phase. B) Right internal carotid angiogram (anteroposterior view). The left anterior and middle cerebral artery were opacified via the anterior communicating artery. C) Left common carotid angiogram two weeks after onset. The left internal carotid artery was opacified like a string in arterial phase. D) Lateral view of PTA using Parodi's system. The common carotid artery and the orifice of the external carotid artery was occluded with a balloon and the stenotic portion was dilated with a PTA balloon. E) Lateral view of stent deployment using Parodi's system. The SMART stent was deployed under common and external carotid occlusion. F) A left common carotid angiogram after stenting. The stenotic portion was well dilatated after stenting. G) A left common carotid angiogram 6 months after stenting. The stenotic portion was wide open.
