  • Title: Additional frozen elephant trunk as a bailout for a misdeployed frozen elephant trunk in the false lumen in a patient with acute aortic dissection.

    Journal: Eur J Cardiothorac Surg; 2020 Feb 01; 57(2):399-401. PubMed ID: 31364695.
    Abstract:
    Using a frozen elephant trunk (FET) in patients with acute aortic dissection is an effective method to induce aortic remodelling after surgery. A 40-year-old man with Stanford type A acute aortic dissection underwent emergency total arch replacement with FET. The FET was inserted into the descending aorta under direct vision. However, transoesophageal echocardiography after the deployment of the FET revealed that it was misdeployed in the false lumen. An additional FET was deployed in the true lumen to redirect the blood flow to the true lumen. The patient was discharged from the hospital without any major complications. Computed tomography 6 months after surgery revealed enhanced aortic remodelling without any signs of stent graft-induced new entry. Additional deployment of a FET into the true lumen could be an option for a misdeployed FET in the false lumen.
