title: [Anastomotic Pseudoaneurysm after Aortic Root Replacement].
abstract: Aortic root replacement has been an established standard procedure to treat annuloaortic ectasia (AAE) or aortic root aneurysm associated with significant aortic valvular disease. The long-term outcome after the surgery has also been favorably reported;however, an occurrence of anastomotic pseudoaneurysm remains a dreadful and serious complication. Detection of asymptomatic pseudoaneurysm used to be a challenge, because conventional computed tomography (CT) scan often fails to reveal a presence of pseudoaneurysm formation mainly due to remarkable artifact from prosthetic valve or motion effect. Recent advance in electrocardiogram (ECG)-gated 3-dimentional (3D)-CT has led to visualize even a small pseudoaneurysm and delineate an exact origin of a pseudoaneurysm. This powerful diagnostic modality enables us to precisely plan therapeutic strategy to accomplish efficacious surgical repair or interventional radiological treatment when possible.
