Objectives: The aim of this study was to evaluate the fate of the downstream aorta following open aortic repair for acute DeBakey type I aortic dissection comparing total arch replacement (TAR) with the elephant trunk (ET) technique versus non-total arch replacement (non-TAR)., Methods: From October 1999 to December 2016, 267 patients underwent open repair for acute DeBakey type I aortic dissection. A tear-oriented strategy was mainly used to determine the extent of graft replacement. Hospital mortality was 10.0% (12/120 patients) in the TAR group and 17.0% (25/147 patients) in the non-TAR group (P = 0.070). Late outcomes were compared in 230 hospital survivors (TAR: n = 108 and non-TAR: n = 122). Mean follow-up was 6.5 ± 4.6 years. The aortic diameters were measured at 4 levels, across 6 time points using computed tomography., Results: Freedom from additional aortic surgery for distal dilation was significantly better in the TAR group than the non-TAR group (TAR: 97.5 ± 1.8% at 5 years and non-TAR: 88.2 ± 3.4% at 5 years, P = 0.045). Freedom from a distal aortic event was also significantly better in the TAR group compared with the non-TAR group (TAR: 97.2 ± 1.6% at 5 years and non-TAR: 80.7 ± 4.2% at 5 years, P = 0.013). In the non-TAR group, the aortic arch diameter significantly increased (P < 0.001). Significant aortic remodelling occurred at the proximal descending aorta in the TAR with ET group (P < 0.001)., Conclusions: The TAR with ET reduced the need for additional distal aortic repair compared to non-TAR. TAR with ET prevented unfavourable aortic growth in both the aortic arch and the proximal descending aorta., (© The Author(s) 2018.

Objective: To present a surgical strategy for aortoesophageal fistula (AEF)., Methods: From October 1999 to May 2017, 27 patients with AEF were treated at Kobe University Hospital. After 9 patients with malignancies or fish bone penetration were excluded, 18 patients who had AEF secondary to aortic lesions were investigated. The mean age was 67.2 ± 10.4 years, and the male/female ratio was 16:2. Twelve patients had a nondissection thoracic aneurysm, and 6 patients had a chronic aortic dissection. Six patients were in shock. Seven patients had a previous thoracic endovascular aortic repair (TEVAR) in the descending aorta, 2 patients had descending aorta replacement, 1 had hemiarch replacement, and 2 had total arch replacement. As the first treatment for AEF, 3 patients underwent TEVAR as destination therapy, 3 patients had a bridge TEVAR to open surgery, 1 patient had an extra-anatomical bypass from the ascending aorta to the abdominal aorta, and 11 patients had an in situ reconstruction of the descending aorta. The esophagus was resected in 16 patients, and an omental flap was installed in 16 patients. Additional procedures were extra-anatomical bypass in 2 patients and in situ reconstruction of the aorta in 3 patients., Results: Hospital mortality was noted in 4 patients (22.2% persistent sepsis, n = 3: pneumonia, n = 1). However, since 2007, only 1 of 13 patients has died (pneumonia). Late death occurred in 5 patients, due to pneumonia, cerebral bleeding, diarrhea, sudden death, and persistent infection. Actuarial survival was 42.4 ± 12.8% at 5 years and freedom from aorta-related death was 59.4 ± 13.5% at 5 years. Nine patients achieved completed reconstruction of the esophagus 172 ± 57 days after initial surgery., Conclusions: Although a comparative study was not performed, 1-stage surgery consisting of resection of an aneurysm and esophagus, in situ reconstruction of the descending aorta, and omental flap installation provided a better outcome in the treatment for AEF. Bridging TEVAR to the open surgery is a useful adjunct in patients with AEF with hemorrhagic shock. Later reconstruction of the esophagus can be performed in the survivors., (Copyright © 2017 The American Association for Thoracic Surgery. Published by Elsevier Inc. All rights reserved.)
