[Stent-in-Stenting for In-Stent Stenosis after Carotid Artery Stenting:A Report of 2 Cases].

ABSTRACT

Standard strategy for the treatment of subacute in-stent stenosis after carotid artery stenting remains controversial. We report the successful application of stent-in-stenting in 2 patients with subacute in-stent stenosis of the internal carotid arteries (ICA). The postoperative courses of both patients were uneventful, and the patency of the ICA was confirmed at the 2-year follow-up. In this study, medical treatment was not effective, and therefore, stent-in-stenting was used as an alternative treatment for subacute in-stent stenosis.
