Key result
Bare metal stenting closes tears and reduces false-to-true lumen ratio ~50% in simulated aortic dissection.
Why the study?
Endovascular repair for aortic dissection with stent grafts has limitations in application scope and complications, prompting evaluation of a large self-expandable bare metal stent.
Does a 32mm self-expandable bare metal stent improve remodeling outcomes in a computational model of aortic dissection?
Population

Does a 32mm self-expandable bare metal stent improve remodeling outcomes in a computational model of aortic dissection?
Finite element analysis demonstrates that a large self-expandable bare metal stent can successfully close tears and improve true lumen area in an ideal aortic dissection model, suggesting feasibility as an alternative to stent grafts.
Hou et al. (2024) studied Aortic dissection. 32mm bare metal stent was evaluated on Remodeling outcomes of the dissected aorta (tear closure, lumen area ratio, vessel diameter, stent apposition). Deployment of a 32mm bare metal stent in a simulated aortic dissection model successfully closed tears and decreased the false-to-true lumen area ratio by more than 50%.
