FET results are comparable with those of the published results of the conventional elephant trunk technique. FET is an ideal landing zone for subsequent transfemoral endovascular completion. Patients with graft infections may have dismal results.
The Thoraflex Hybrid graft adds to the frozen elephant trunk concept for treating aortic arch and descending aortic disease. Implantation of the Thoraflex Hybrid graft resulted in excellent outcomes and beneficial aortic remodeling during follow-up. This graft increases surgeons' armamentarium in the treatment of complex and diverse aortic arch pathology.
In selected patients with combined aortic arch and descending aortic aneurysms limited to the proximal descending aorta, the FET approach potentially allows for single-stage therapy, whereas a second-stage operation is inevitable with the classic ET approach. Moreover, owing to the availability of prefabricated, easy-to-use, FET, hybrid prostheses that result in significantly better outcomes in patients who have acute aortic dissection, type A, and if necessary, and provide an ideal "landing zone" for future endovascular completion, the classic ET procedure is "freezing," in the sense that it is being replaced by the FET approach.
In situ graft-sparing surgical therapy is safe and effective if diagnosis and treatment of aortic graft infection is initiated promptly and aggressively (ideally <1 month post-surgery). Our method produces good midterm results (3 years). For aortic graft infections that become clinically apparent >3-6 months after surgery, replacement of grafts with biological conduits (homografts or pericardial xenografts) most likely remains the best treatment option.
Medium-term results after lung transplantation with organs procured after circulatory death are comparable with those obtained after standard lung transplantation. Therefore, DCD could be used to significantly increase the donor pool.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
