Abstract:
Pseudoaneurysms are a rare complication of cardiovascular surgery, caused by disruption of the aortic structure (adventitia, media, and intima). Some reports have observed an extremely high mortality rate associated with the open surgical repair of pseudoaneurysms. In elderly or highly frail patients, the use of less invasive procedures is preferable. In this article, we report a case of an octogenarian who had a symptomatic ascending aortic pseudoaneurysm and a history of two sternotomies and present the successful treatment strategy. We treated the patient via an endovascular procedure using an Amplatzer Vascular Plug II (AVP II). After the intervention, the symptoms of the patient resolved. A computed tomography scan performed 1 year after the procedure confirmed the exclusion of the pseudoaneurysm.
