Microfocal X-Ray Computed Tomography Post-Processing Operations for Optimizing Reconstruction Volumes of Stented Arteries During 3D Computational Fluid Dynamics Modeling [PDF]

, 2005
Restenosis caused by neointimal hyperplasia (NH) remains an important clinical problem after stent implantation. Restenosis varies with stent geometry, and idealized computational fluid dynamics (CFD) models have indicated that geometric properties of ...

Lateral Mucosal Flap With Steroid‐Eluting Implant in Revision Draf Type III Frontal Sinus Surgery

The Laryngoscope, EarlyView.
This technical note introduces a novel endoscopic strategy that integrates a laterally based endonasal mucosal flap with a bioabsorbable steroid‐eluting implant to prevent restenosis following revision of Draf type III frontal sinus surgery. The vascularized flap is stabilized and maintained in close apposition to the underlying bone by a self ...

Influence of Tracheostomy Level on Surgical Management of Pediatric Airway Stenosis

The Laryngoscope, EarlyView.
Tracheostomy location is a critical determinant of surgical complexity and outcomes in pediatric laryngotracheal stenosis. Misplacement may lead to longer tracheal resections, an increased need for stoma relocation, more complex reconstruction, and secondary stenosis. Strategic planning of tracheostomy position can improve surgical outcomes.

Mono‐ and Bivalent Poly(iso‐butylene)‐Alanines for Drug‐Delivery of Nimodipine and Triamcinolone Acetonide

Macromolecular Rapid Communications, EarlyView.
Mono‐ and bivalent‐, alanine‐modified poly‐iso‐butylenes, folding into beta‐sheets, were prepared by living carbocationic polymerization and subsequent endgroup modification. These PIB‐conjugates are useful as solid polymers for the drug release of triamcinolone and nimodipine. ABSTRACT Poly‐iso‐butylene (PIB) is a well known biocompatible polymer with

In Stent Restenosis Predictors after Carotid Artery Stenting

Stroke Research and Treatment, 2010
Purpose. The long-term efficacy of carotid artery stenting is debated. Predictors of stent restenosis are not fully investigated. Our aim was to assess the incidence of long term restenosis after CAS and to identify some predictors of restenosis. Methods.

Radiofrequency wire-assisted recanalization of chronic venous stent occlusions

Journal of Vascular Surgery Cases and Innovative Techniques
Venous in-stent reocclusion can result in recurrent obstructive symptoms. Occlusions that are recalcitrant to traditional crossing techniques are inaccessible to effective therapies. However, radiofrequency-assisted recanalization techniques can mitigate
