RT Journal Article SR Electronic T1 Percutaneous device closure of a large complex aortic root pseudoaneurysm JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e235545 DO 10.1136/bcr-2020-235545 VO 13 IS 9 A1 Patrick Tran A1 Jamal Nasir Khan A1 David Hildick-Smith A1 Martin Been YR 2020 UL http://casereports.bmj.com/content/13/9/e235545.abstract AB Pseudoaneurysm of the aorta is a rare and high-risk complication of native aortic valve endocarditis and can develop following cardiac surgery for aortic valve and root disease. If left untreated, there is a significant risk of aortic wall rupture and fatality. Given the high risk of mortality associated with traditional open surgical repair of aortic pseudoaneurysms, endovascular approach is a potentially favourable alternative. We describe a unique case of a young woman with a large and complex paraprosthetic pseudoaneurysm with multiple communicating fistulae which was successfully percutaneously treated with two occluder devices. In this technically challenging case, a minor but unique procedural complication is also illustrated.
