Development of a prostacyclin-agonist-eluting aortic stent graft enhancing biological attachment to the aortic wall.
Stent graft-related complications, including endoleaks and graft migration, are partly attributed to insufficient graft attachment to the aortic wall. ONO-1301, a stable synthetic prostacyclin agonist, reportedly reorganizes extracellular matrices, enhancing tissue healing. We hypothesized that ONO-1301-eluting stent grafts may strengthen graft attachment to the aortic wall. ⋯ In canines, the ONO-1301-eluting stent graft enhanced tissue reorganization and improved the attachment between the graft and the aortic wall. This new device may be useful in preventing inadequate graft attachment to the aortic wall.
