Over the past decades, great progress has been made in the treatment modalities for aortic arch diseases. Open surgical repair is considered the gold standard for patients suitable for surgery, but is associated with high invasiveness and significant morbidity and mortality. Recently, significant advances in the endovascular repair of lesions to reconstruct the aortic arch branches have emerged; hybrid techniques, chimney stents, preloaded fenestration, in situ fenestration, and branched stent-grafts are used as alternatives to open surgery. However, these endovascular techniques vary in characteristics, procedures, postoperative risks (especially for neurological complications), and prognosis.
Traditional stent-grafts are not designed for the aortic arch and the ascending aorta, resulting in an unclear impact on long-term patient outcomes. The aortic arch has specific tortuous anatomy and complex interactions between blood flow and the aortic wall. Stent-grafts implanted in the arch and the ascending aorta might have additional effects on the aortic wall, flow dynamics, and safety of patients. It's urged to deeply understand the interaction of the stent-graft with the aortic wall, investigate the fluid mechanics of the arch and ascending aorta, and ultimately develop further stent-grafts that suit the arch and favor the safety of patients.
In this Research Topic, we would like to create a forum for current advances in the endovascular repair and branch reconstruction technique for the aortic arch, the long-term prognosis, and the related challenges we are facing. Furthermore, submissions on the development of new stent-grafts and new techniques, basic research examining the interaction between the stent and aorta, and the fluid mechanics of the arch and the ascending aorta are also encouraged.
We welcome articles on the subjects of, but not limited to:
1) Long-term outcomes of parallel graft (chimney or periscope stent) and how to reduce endoleak.
2) Precise location, patency of bridging stents, durability, experimental analysis on fenestrations, including customized or physician-modified preloaded fenestrations (or scallop) and in situ fenestrations.
3) Inner or outer branched, 1 or 2 branches (even 3), requirements for landing zone, patency of bridging stents on branched stent-grafts.
4) Personalized prostheses or approaches to endovascular management of arch lesions.
5) New stent-grafts suitable for the arch, less harm to the aortic wall, more prevention from cerebral perfusion and stroke, and also new delivery systems suitable for the arch with precise location.
6) How to decrease the risk of complications, such as stroke during these endovascular procedures, retrograde type A dissection after TEVAR, etc.
7) Curvature of the arch: anatomy, flow dynamics, and interaction with stent-grafts.
