Abstract:
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.
