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.

Sarcopenia did not predict hospital death following total arch replacement, but it was negatively associated with overall survival. Sarcopenia can be an additional risk factor to estimate the outcomes of thoracic aortic surgery.

Aortoesophageal fistula is a critical and life-threatening disease. The cardiovascular strategy for graft replacement has been widely discussed. However, the surgical strategy of esophageal resection and reconstruction for aortoesophageal fistula has rarely been discussed. The objective of this study is to establish a surgical strategy and procedure of esophageal resection and reconstruction for aortoesophageal fistula. Eleven patients with aortoesophageal fistula who underwent aortic graft replacement and esophagectomy between 2008 and 2015 at Kobe University Hospital were enrolled in this study. Patient characteristics, operative methods, and clinical outcomes were obtained by retrospective chart review. All 11 patients underwent graft replacement, esophagectomy, and omental wrapping. Ten esophagectomies were simultaneously accomplished in the same operative field as aortic graft replacement. Seven patients underwent subtotal esophagectomy from a left thoracotomy, and three patients underwent upper hemiesophagectomy from a median sternotomy. The other patient underwent staged esophagectomy from a right thoracotomy. Seven of 11 patients (63.6%) successfully underwent staged esophageal reconstruction. Pedicled jejunal transfer with supercharge and superdrainage were performed in six patients, and ileocecal reconstruction was performed in one patient. Median survival time in the patients with esophageal reconstruction was 21 months while that in the patients without esophageal reconstruction was 10 months. Six of 7 patients (85.7%) who underwent esophageal reconstructions were alive. Our surgical strategy for aortoesophageal fistula, which includes simultaneous graft replacement and esophagectomy in the same operative field and staged reconstruction by pedicled jejunal transfer to ensure omental wrapping, is feasible and promising.

In terms of freedom from aortic regurgitation and valve function, similar outcomes were achieved in both despite different repair techniques used for fixation of commissures during valve-sparing aortic root replacement in BAV. However, attention should be paid to patients with 180° commissural reposition because of a trend towards higher TVPG.

IntroductionAlthough thoracic endovascular aortic repair (TEVAR) has become a promising treatment for complicated acute type B dissection, its role in treating chronic post-dissection thoraco-abdominal aortic aneurysm (TAA) is still limited owing to persistent retrograde flow into the false lumen (FL) through abdominal or iliac re-entry tears.ReportA case of chronic post-dissection TAA treatment, in which a dilated descending FL ruptured into the left thorax, is described. The primary entry tear was closed by emergency TEVAR and multiple abdominal re-entries were closed by EVAR. In addition, major re-entries at the detached right renal artery and iliac bifurcation were closed using covered stents. To close re-entries as far as possible, EVAR was carried out using the chimney technique, and additional aortic extenders were placed above the coeliac artery. A few re-entries remained, but complete FL thrombosis of the rupture site was achieved. Follow-up computed tomography showed significant shrinkage of the FL.DiscussionIn treating post-dissection TAA, entry closure by TEVAR is sometimes insufficient, owing to persistent retrograde flow into the FL from abdominal or iliac re-entries. Adjunctive techniques are needed to close these distal re-entries to obtain complete FL exclusion, especially in rupture cases. Recently, encouraging results of complete coverage of the thoraco-abdominal aorta with fenestrated or branched endografts have been reported; however, the widespread employment of such techniques appears to be limited owing to technical difficulties. The present method with multiple re-entry closures using off the shelf and immediately available devices is an alternative for the endovascular treatment of post-dissection TAA, especially in the emergency setting.

In the first case, a 60-year-old man was referred to our hospital for a sudden stomachache. A computed tomography scan revealed a thrombus at ascending aorta with acute mesenteric ischemia. In the second case, a 62-year old man developed a hypoglycemic attack with unbalanced diet. A computed tomography showed a thrombus at ascending aorta without thromboembolism. Laboratory data of both cases showed elevated platelet and a loss of antithrombin III. We administered a resection of thrombus to prevent a systemic embolism. We suggested that the risk of ascending aorta thrombus was elevated platelet and a loss of antithrombin III.
