Introduction: New treatment options, like endovascular aortic repair, reduced the mortality rate of patients suffering from complications after an acute type A aortic dissection repair. Nevertheless, initial successful treatment of an aortic dissection does not fully eliminate the risk of later adverse aortic events like anastomotic pseudoaneurysm. Pseudoaneurysm of the
anastomosis between the ascending and the arch graft could initiate complications like peripheral embolization, dysphagia or compression of mediastinum organs. Re-operation via re-sternotomy bears enormous morbidity and mortality for these patients. There is a high unmet need for percutaneous therapeutic options to treat pseudoaneurysms.

Case Presentation: A 59-year-old-man treated 15 years ago for type A aortic dissection, was hospitalized due to intermittent abdominal pain. A detailed examination revealed 2 pseudoaneurysms: 1 symptomatic at the level of the reimplanted celiac trunk and 1 asymptomatic at the anastomosis between the brachiocephalic trunk and the aortic arch graft. Due to multiple co-morbidities and previous operations, the risk for surgery was considered too high. Both pseudoaneurysm were treated percutaneously, the symptomatic 1 with covered stent and the asymptomatic with Amplatzer septal-occluder.

Discussion: We present an alternative percutaneous therapy approach for treatment of pseudoaneurysm using a septaloccluder. A follow-up computed tomography 3 months later showed successfully excluded pseudoaneurysm.
