“…In the 7 non-comparative arch zone 2 and proximal studies, one reported both 30-day and in-hospital mortality ( 19 ), four in-hospital ( 18 , 25 , 27 , 28 ) and only two 30-day mortality ( 26 , 29 ). Here, the overall mortality rate ranged from 2.8–9.2% with an average rate of 5.4% ( Table 3 ).…”

Background and Objective: Since 2003, the Frozen Elephant Trunk (FET) technique has attained rising popularity for treating extensive aortic arch pathologies such as acute and chronic aortic dissection, as well as thoracic aortic aneurysm. Conventionally, the FET procedure included a complete resection of the aortic arch and, subsequently, a distal aortic anastomosis of the prosthetic part of the hybrid graft in arch zone 3. Simultaneous to the introduction of the FET technique, the traditional Elephant Trunk technique was simplified by adding debranching techniques which allows for proximalization of the distal aortic anastomosis. Nowadays, modern concepts of aortic arch surgery combine the FET technique with proximalization of the distal anastomosis in arch zone 2 or further proximal, achieved by using different debranching techniques. This review describes different debranching techniques to facilitate arch reconstruction, and aims to critically assess the outcomes and potential clinical advantages of proximalization using debranching in FET surgery. Methods: We conducted a search using the PubMed and Google Scholar electronic databases to evaluate published outcomes of different debranching techniques. An overview of the data synthesis of 21 included studies is reported.

Background: The aim of our study was to provide a summary of applied percutaneous aortic anastomosis leak (AAL) closure techniques after frozen elephant trunk (FET) procedure for aortic dissection and describe the procedural and mid-term outcomes in a consecutive cohort of patients at our center. Methods: All patients who underwent percutaneous closure of AAL after FET between January 2018 and December 2020 were identified. Three different strategies were employed: (I) the retrograde technique; (II) the true-to-false lumen loop technique; and (III) the antegrade technique. Procedural and short-term results were assessed.Results: A total of 34 AAL closure procedures were performed in 32 patients. The mean age was 44.3±9.1 years, and 87.5% of patients were male. Successful device deployments were achieved in 36 leaks (100%). Immediate residual leaks were mild and moderate in 37.5% and 9.4% of patients, respectively. After a mean follow-up of 47.1±24.6 months, reduction in AAL to mild or less was accomplished in 90.6% of patients. Complete thrombosis and basically complete thrombosis of the FET's segment false lumen were achieved in 75.0% and 15.6% of patients, respectively. The maximal diameter of FET's segment false lumen significantly decreased by 13.6±8.7 mm (from 33.0±9.4 to 19.4±16.2 mm, P<0.001).Conclusions: Percutaneous closure of AAL after FET procedure was associated with false lumen reduction of aortic dissection. The magnitude of benefit was greatest with AAL reduction to a grade of mild or less. Therefore, attempts should be made to reduce AAL as much as possible.
