Proximal migration of a tapered open-cell stent after carotid artery stenting for restenosis following endarterectomy

Delayed Migration of Tapered Open-Cell Design Carotid Stent: A Case Report

“…In published cases, stent migration was observed not only during follow-up, as in our case, but also immediately after CAS ( Table 1 ) [ 4 - 7 , 10 ]. In general, endothelial growth after stenting integrates the stent into the vessel wall and prevents migration.…”

“…Interestingly, stent migration does not appear to be affected by stent design, such as open-cell [ 7 , 10 ] or closed-cell [ 4 , 6 ]. Closed-cell stent migration may result from the watermelon-seeding effect, where the stent moves toward the larger proximal vessel due to diameter differences [ 6 ].…”

“…In published cases, stent migration was observed not only during follow-up, as in our case, but also immediately after CAS (Table 1). [4][5][6][7]10 In general, endothelial growth after stenting integrates the stent into the vessel wall and prevents migration. Within a few weeks, the stent struts are expected to be integrated into the vessel wall, making migration or dislodgement difficult.…”

“…Previous studies have reported various complications associated with CAS, including stroke, intracranial hemorrhage, in-stent stenosis, and occlusion, complicating folding deformity [ 2 , 3 ]. Especially, delayed migration of an open-cell design carotid stent is a very rare complication [ 4 - 7 ]. Herein, we present a case of delayed migration of a tapered opencell design carotid stent.…”
