174. Post-Deployment Modifications of Stent with Endothelial Cells

Carotid Artery Stent Continued Expansion Days After Deployment, Without Post Stent Deployment Angioplasty

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 intraoperativ...

Post-biliary sphincterotomy bleeding despite covered metallic stent deployment

OBJECTIVES Several endoscopic techniques have been proposed for the management of post-sphincterotomy bleeding. Lately, self-expandable metal stents deployment has gained popularity especially as a rescue therapy when other endoscopic techniques fail. METHODS-RESULTS We report the case report of a massive post-sphincterotomy bleeding in a patient with a self-expandable metal stent in the bili...

Antiplatelet therapy following stent deployment.

Material-based deployment enhances efficacy of endothelial progenitor cells.

Cell-based therapies are attractive for revascularizing and regenerating tissues and organs, but clinical trials of endothelial progenitor cell transplantation have not resulted in consistent benefit. We propose a different approach in which a material delivery system is used to create a depot of vascular progenitor cells in vivo that exit over time to repopulate the damaged tissue and particip...

Genetically engineered endothelial cells remain adherent and viable after stent deployment and exposure to flow in vitro.

Intravascular stents, currently in experimental human use for recurrent arterial stenosis, are plagued by subacute thrombosis. As a therapeutic approach to stent-related thrombosis, we and others have suggested coating stents with endothelial cells before implantation. In a previous study we demonstrated the feasibility of coating stents with endothelial cells that were genetically modified to ...
