Endovascular reconstruction of internal carotid artery dissection in patients with acute ischemic stroke using the Wingspan stent

Abstract

Objective The purpose of this study is to demonstrate our experience in endovascular reconstruction of carotid dissections using the Wingspan Stent System™ (Boston Scientific, Natick, MA, USA), a device we use because of its high radial force and its navigation in extreme curves. Methods We treated 11 consecutive patients with acute ischemic stroke due to carotid dissection with the Wingspan stent, in the cervical carotid artery. Results Functional evaluation revealed that 10 of the 11 patients were independent at 3 months post surgery and that the 11 stents used were found to be patent at the 6-month follow-up digital subtraction angiography (DSA). Conclusions The Wingspan stent is an alternative to classic carotid stents and flow diverters for the treatment of cervical internal carotid artery (ICA) dissection associated with ectasias or large loops. The device remains patent over the long term and it is not associated with arterial wall complications.
