[Partial Arch Repair for Reruptured Aortic Arch Aneurysm due to Endoleak After 2-debranching Thoracic Endovascular Aortic Repair:Report of a Case].

ABSTRACT

A 67-year-old male was admitted to our hospital for sudden onset chest pain and hoarseness. He underwent 2-debranching thoracic endovascular aortic repair for a ruptured aortic arch aneurysm four years prior. However, computed tomography (CT) revealed an aneurysmal rerupture due to a typeⅠa endoleak. We performed partial arch replacement with uncovered stent removal under intermittent hypothermic circulatory arrest. We needed to be more careful than usual open heart surgery because a non-anatomical bypass procedure was performed. The surgery was successful without any major complications, and the patient was discharged on the 23th postoperative day. Reinterventions post-endovascular repair are sometimes difficult;thus, open surgery could be useful for arch replacement.
