Evaluating stent optimisation technique (StentBoost?) in a dedicated bifurcation stent (the Tryton?)

摘要

Background/Purpose: To evaluate the use of StentBoost? in the Tryton? dedicated SideBranch Stent. Methods & Results: The Tryton? SideBranch Stent has been effectively used to manage complex bifurcations. However, the paucity of scaffolding in the proximal part of the stent makes it often difficult to visualise under standard radiographic imaging. We set out to evaluate whether by using an augmented radiographic imaging technique it was possible to aid visualisation of the stent. In particular the so call 'wedding ring' band which is crucial to the procedural success. We further evaluated whether it was possible to determine the apposition of the stent at the carina, its coverage and the ability to aid recrossing of the struts closest to the carina as well as the added radiation exposure. Conclusions: StentBoost? was found to be invaluable to the procedural success of the Tryton? deployment without adding any extra cost to the procedure and with only a 3.7% increase in radiation to the patient. It allowed enhanced visualisation in all cases to aid apposition, recrossing and coverage.
