Abstract
<h4>Objective</h4>To examine the management of distal aortic disease after total arch replacement with the frozen elephant trunk (TAR + FET) in patients with chronic thoracic aortic disease.<h4>Methods</h4>Two centre retrospective study of consecutive patients treated between January 2010 and December 2019. Primary endpoint was 30 day/in hospital mortality. Secondary end point was mid-term survival. Data are presented as median (IQR). Chi squared or Fisher's exact test was used as appropriate. Estimated survival (standard error) was assessed by the calculating Kaplan-Meier product limit estimator with right censoring of survival data. A p value of < .050 was considered to be statistically significant. STROBE guidelines were followed.<h4>Results</h4>A total of 158 patients (72 men; median age 70, IQR 64, 75; median distal aortic diameter 58 mm (46, 68; 127 aneurysmal disease, 31 chronic dissection) underwent TAR + FET. Peri-operative mortality was 10.1% (9/107 elective, 7/51 non-elective). Of 74 (46.8%) patients with a primary distal seal, seven (9.5%) died peri-operatively, distal seal was maintained during follow up in 51, nine underwent late distal repair (two planned, seven unplanned; one open, eight endovascular; one peri-operative death) with a median interval to unplanned repair of 777 days (462, 1480), and seven with loss of seal had no intervention. Distal seal failed in 2/28 (7%) patients with a distal seal length > 30 mm and device oversizing > 10%, compared with 12/39 (31%) patients who did not meet these criteria (p = .031). In 84 patients without primary distal seal, nine (10.7%) died peri-operatively, the distal aorta remained below the size threshold for repair during follow up in 12 patients, 44 had distal repair (median aortic diameter 64 mm, 60, 75; eight open, one hybrid, 35 endovascular repairs; no mortality) at a median of 256 days (135, 740), and 19 did not have distal repair at the end of the follow up period: six died before planned repair at a median interval of 115 days (85, 120); eight were considered unfit; one was assessed as fit but declined; and four patients were awaiting assessment). Median follow up was 46 months (26, 75): no patients were lost to follow up. Estimated ± standard error five year survival was 61.5 ± 4.1%: elective 70.6 ± 4.7%, non-elective 43.2 ± 7.2%.<h4>Conclusion</h4>TAR + FET achieved primary distal seal in 47% of patients, but late failure occurred in 21% of patients. Distal repair was ultimately indicated in 84% of survivors without primary distal seal and of these 70% underwent repair, almost 10% died before planned repair, and 13% were considered unfit. Earlier distal endovascular repair and better assessment of patient fitness may improve mid-term outcomes.
