Cannulation of the ascending aorta is the recognized method to achieve arterial return during cardiopulmonary bypass. Mediastinal infection after cardiac surgery can cause disruption at the point of insertion, and give rise to a pseudoaneurysm in the ascending aorta. Although rare, a pseudoaneurysm can occur without clear evidence of infection. Here we report two cases that received aortic valve replacement and that developed ascending aortic aneurysms after surgery. Based on our clinical findings, these aneurysms were related to the arterial cannulation into the aorta and not to any infection.
升主动脉插管是体外循环期间实现动脉回血的公认方法。心脏手术后纵隔感染可导致插管处破裂，并在升主动脉形成假性动脉瘤。尽管罕见，但假性动脉瘤可在无明确感染证据的情况下发生。在此，我们报告两例接受主动脉瓣置换术并在术后发生升主动脉瘤的病例。根据我们的临床发现，这些动脉瘤与主动脉插管有关，而非任何感染所致。
