Carotid Artery Stent Continued Expansion Days After Deployment, Without Post Stent Deployment Angioplasty
نویسندگان
چکیده
This is a carotid artery stent (CAS) case report, which avoids post-stent deployment angioplasty (Post-SDA), with duplex confirmed continued stent expansion at 1, 3 and 30-day post deployment. This report confirms that self-expanding nitinol stents in the carotid artery may not require Post-SDA. We believe CAS can be performed without Post-SDA, which helps reduce the occurrence of intraoperative hemodynamic depression.

Efficacy of treatment of severe carotid bifurcation stenosis by using self-expanding stents without deliberate use of angioplasty balloons.
BACKGROUND AND PURPOSE One of the limitations of carotid artery angioplasty is the potential for embolic stroke. Our purpose was to assess whether the force of a self-expanding stent alone is usually sufficient to dilate severely stenotic atherosclerotic plaques without the deliberate use of an angioplasty balloon. If so, the procedural stroke risk might be reduced. METHODS Over a 30-month pe...
متن کاملStent deployment resolves a petrous carotid artery angioplasty dissection.
A patient with a symptomatic petrous carotid artery stenosis underwent balloon angioplasty, which was complicated by a flow-limiting dissection. The problem was resolved by deploying a balloon-expandable coronary stent. The patient suffered no neurologic deficit, was discharged within 12 hours, and was asymptomatic at last follow-up, 5 months after the procedure, without warfarin therapy. This ...
متن کاملTransarterial wall oxygen gradients at the deployment site of an intra-arterial stent in the rabbit.
Intimal hyperplasia, common at the deployment site of an intra-arterial stent, may be caused by artery wall hypoxia. The purpose of this study was to determine the effect of an intra-arterial stent on artery wall oxygen concentrations. Transarterial wall oxygen gradients were measured by microelectrode at stent deployment sites in New Zealand White rabbits. Thinned artery walls and decreased ox...
متن کاملPredictors and outcomes of stent thrombosis: an intravascular ultrasound registry.
AIMS To investigate whether intravascular ultrasound provides additional information regarding the prediction of stent thrombosis, a retrospective multicentre registry was designed to enrol patients with stent thrombosis following stent deployment under ultrasound guidance. METHODS AND RESULTS A total of 53 patients were enrolled (mean age 61+/-9 years) with stable angina (43%), unstable angi...
متن کاملMechanisms and predictors of carotid artery stent restenosis: a serial intravascular ultrasound study.
OBJECTIVES The aim of this study was to determine the mechanisms and predictors of carotid artery restenosis after carotid artery stenting (CAS) using serial intravascular ultrasound (IVUS) imaging. BACKGROUND Carotid artery stenting is increasingly used to treat high-grade obstructive carotid disease, but our knowledge of carotid in-stent restenosis and remodeling remains limited. METHODS ...
