【 摘 要 】

Background: The frozen elephant trunk technique is useful in aortic arch repair; however, some adverse events are associated with the Frozenix J-graft. We designed a technique to prevent these adverse events and achieve easy anastomosis (Total Exclusion of the Non-Stent part of Frozenix using an Everting anastomosis [TENSE]), and we assessed the outcomes of this technique in the present study. Methods: From April 2017 to May 2021, 44 patients with aortic arch disease underwent TENSE, in which the proximal stump of the stent part of Frozenix was matched to the distal anastomosis end between the left common carotid and left subclavian arteries. Results: The median age of the patients (35 men, 9 women) was 76.5 years. The predicted mortality and morbidity rates were 10.0% and 40.2%, respectively, according to the JapanSCORE II. Two patients (4.5%) died of aneurysm rupture and interstitial pneumonia, respectively, during hospitalization. Four patients (9.1%) who developed postoperative cerebral infarction had a previous cerebral infarction (P=0.010). No patients developed spinal cord complications or Frozenix kinking. Follow-up computed tomography showed no endoleaks or aneurysmal dilatation, although one patient had possible distal stent graft-induced new entry. Conclusions: Our strategy provided good early outcomes without spinal cord complications or Frozenix kinking in patients with aortic arch disease. Continuous follow-up is needed to avoid missing distal changes.
