Methods: This was a retrospective single-centre analysis of patients who received TEVAR after FET for rTAAD from January 2012 up to December 2021. The primary endpoint was technical success. Safety parameters included 30-day\/in-hospital morbidity and mortality. Furthermore, mid-term clinical and morphological outcomes were evaluated. Results: Among 587 TEVAR procedures, 60 patients (11 with connective tissue disorders) who received TEVAR after FET for rTAAD were identified. The median interval between FET and TEVAR was 28.5 months. Indications for TEVAR after FET were true lumen collapse distal to FET prosthesis (n = 7), dSINE (n = 2), planned completion (n = 13) and aortic diameter progression (n = 38). In forty-seven patients, TEVAR was performed in an elective setting; eight and six patients were operated on in an urgent or emergency setting, respectively. All TEVAR procedures were successfully completed. The 30-day mortality and spinal cord ischemia rates were 1.7%. During a median follow-up of 37 months, two further patients died. Nine patients had to undergo a further aortic intervention: fenestrated stent-graft (n = 3) or open repair of the infrarenal abdominal aorta (n = 6). Conclusions: Complementary TEVAR following FET for rTAAD showed excellent technical success and low perioperative risk, supporting the feasibility and safety of this strategy. Despite the favourable mid-term survival, certain patients might require a further aortic procedure.<\/jats:p>","DOI":"10.3390\/jcm13103007","type":"journal-article","created":{"date-parts":[[2024,5,20]],"date-time":"2024-05-20T06:31:58Z","timestamp":1716186718000},"page":"3007","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Complementary Thoracic Endovascular Aortic Repair (TEVAR) after Frozen Elephant Trunk for Residual Type A Aortic Dissection: Perioperative and Mid-Term Outcomes"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9875-4614","authenticated-orcid":false,"given":"Spyridon N.","family":"Mylonas","sequence":"first","affiliation":[{"name":"Department of Vascular and Endovascular Surgery, Faculty of Medicine, University Hospital of Cologne, University of Cologne, 50937 Cologne, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8788-8238","authenticated-orcid":false,"given":"Ravan","family":"Mammadov","sequence":"additional","affiliation":[{"name":"Department of Vascular and Endovascular Surgery, Faculty of Medicine, University Hospital of Cologne, University of Cologne, 50937 Cologne, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8262-8381","authenticated-orcid":false,"given":"Bernhard","family":"Dorweiler","sequence":"additional","affiliation":[{"name":"Department of Vascular and Endovascular Surgery, Faculty of Medicine, University Hospital of Cologne, University of Cologne, 50937 Cologne, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e334","DOI":"10.1161\/CIR.0000000000001106","article-title":"2022 ACC\/AHA Guideline for the Diagnosis and Management of Aortic Disease: A Report of the American Heart Association\/American College of Cardiology Joint Committee on Clinical Practice Guidelines","volume":"146","author":"Isselbacher","year":"2022","journal-title":"Circulation"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Czerny, M., Grabenwoger, M., Berger, T., Aboyans, V., Della Corte, A., Chen, E.P., Desai, N.D., Dumfarth, J., Elefteriades, J.A., and Etz, C.D.
