Key result
Repeat carotid stenting resolves symptomatic stent fracture with zero restenosis at 12 months.
Why the study?
With increasing carotid stent implantations, detection and management of carotid stent fractures causing symptoms remain important clinical concerns.
Case Report (n=2)
Repeated stent implantation appears to be an effective and durable treatment for symptomatic carotid stent fractures, with no recurrence of symptoms or restenosis at 12 months.
Stent fracture warrants consideration in symptomatic post-carotid stent patients; leaves open incidence, risk factors, and surveillance needs.
With increasing numbers of carotid stent implantations, stent fractures likely will be detected in this vessel region. The authors report two cases of stent fracture: one balloon expandable and one self expandable stent fractured and caused symptoms. CT angiography identified the stent fractures. One partial stent fracture in the internal carotid artery caused a significant restenosis. One complete stent fracture in the common carotid artery caused neurological symptoms, but no significant restenosis. Computerized tomographic angiography (CTA) findings were confirmed by conventional angiography and treated by repeated stent implantation. In a 12-month follow-up period, both patients remained further neurologically asymptomatic and there was no restenosis in duplex sonography or CTA.

Boehm et al. (2009) conducted a case report in Carotid stent fracture (n=2). Repeated stent implantation was evaluated on Neurological symptoms and restenosis. Repeated stent implantation successfully treated two cases of symptomatic carotid stent fracture, with both patients remaining neurologically asymptomatic and free of restenosis at 12 months.
