    Abstract:
    INTRODUCTION: A late aortic aneurysm at the site of previous open surgery for coarctation of the aorta (CoA) is a life threatening complication. Several strategies have been reported, however, these strategies have issues. This is the report of a case involving successful ascending to descending aortic bypass concomitant with endovascular embolisation for a pseudoaneurysm. REPORT: The patient was a 23 year old man with a history of patch aortoplasty for coarctation of the aorta (CoA) via a left thoracotomy and patch closure of a ventricular septal defect. Enhanced computed tomography (CT) angiography performed in 2014 revealed a pseudoaneurysm at the site of the previous patch aortoplasty. CT also revealed a hypoplastic and severely kinked aortic arch that made it difficult to perform conventional thoracic endovascular aortic repair for this aneurysm. Therefore in order to prevent rupture, a combination of ascending to descending aortic bypass and endovascular embolisation using Amplatzer vascular plugs and coils was employed. Transection of the aortic arch and transposition of the left subclavian artery were performed to prevent antegrade flow into the aneurysm. DISCUSSION: The aneurysm was successfully excluded without complications. CT performed three years after the operation showed that the pseudoaneurysm had shrunk completely. Extra-anatomic bypass concomitant with endovascular embolisation for a late coarctation patched site aneurysm might be an alternative strategy that should be carefully considered in specific cases.
