Abstract
Background: We report 2 patients who underwent thoracic endovascular aortic repair (TEVAR) for type I endoleak after open stent surgery for thoracic aortic arch aneurysms.
Cases: Case1: An 80-year-old man had undergone aortic valve replacement and total aortic arch repair with the open stent method for aortic valve incompetence and distal aortic arch aneurysm 3 years previously; he developed type-I endoleak 6 months later. Case 2: A 60-year-old man had undergone total arch replacement for type-A aortic dissection 9 years earlier; 5 years later he underwent open stent repair for pseudoaneurysm and reconstruction of the right subclavian artery which had originated from the descending aorta, however, type I endoleak was observed at the anastomotic site. He received resection and suture of the anastomosis and the endoleak disappeared. Then, one year later, follow-up computed tomography (CT) showed type I endoleak at the tip of the stent-graft.
Results: Stent-graft placement was technically successful; neither patient developed major complications. In Case 1 type I endoleak due to migration of the stent-graft developed after the first stent placement, therefore, we performed TEVAR again one year after. In both cases, CT performed during follow-up demonstrated complete thrombosis and patency of the stent-graft during the follow up period.
Conclusion: We performed TEVAR for type I endoleak after open stent surgery for thoracic aortic arch aneurysms in two cases. TEVAR was minimally invasive, safe and effective treatment for type I endoleak after open stent surgery for thoracic aortic arch aneurysms.
