  • Title: Frozen Elephant Trunk Without Circulatory Arrest in Acute Aortic Dissection.
    Author: Di Eusanio M, Gatta E.
    Journal: Ann Thorac Surg; 2021 Aug; 112(2):e143-e145. PubMed ID: 33667459.
    Abstract:
    Aortic arch repair with frozen elephant trunk is increasingly offered to patients with extensive thoracic aortic disease. Given the magnitude of such a procedure, reported postoperative mortality and morbidity have to be considered adequate but not negligible. To further improve postoperative outcomes we developed a hybrid approach allowing frozen elephant trunk to be performed without hypothermia and circulatory arrest. After an initial experience in patients with chronic aneurysms, we successfully adopted the same approach in a patient with type 1 acute aortic dissection. Transfemoral stent-graft deployment, balloon clamping, and an always antegrade aortic perfusion are key elements of the approach presented here.
