Diagnosis of aortic graft infection is challenging, and delayed diagnosis is associated with poor prognosis. Positron emission tomography/computed tomography (PET/CT) has improved diagnostic accuracy.
A patient with a history of congenital heart disease was admitted due to fever. He had a history of four cardiac surgeries, including the Bentall procedure for endocarditis. Blood cultures were negative. A semi-mobile mass was detected in the distal portion of the aortic tube graft in echocardiography. PET/CT scan was used to confirm tube graft infection and to support proceeding to cardiac surgery.
Using multimodality imaging, including PET/CT scan in combination with echocardiography, can improve diagnostic accuracy for the detection of aortic tube graft infection, infection of prosthetic valves, or intra-cardiac devices, especially in high-risk surgical cases.
主动脉移植物感染的诊断具有挑战性，延迟诊断与不良预后相关。正电子发射断层扫描/计算机断层扫描（PET/CT）提高了诊断准确性。
一名有先天性心脏病史的患者因发热入院。他有四次心脏手术史，包括因心内膜炎进行的Bentall手术。血培养阴性。超声心动图检查发现主动脉人工血管远端有一个半活动肿物。PET/CT扫描用于确诊人工血管感染并支持进行心脏手术。
使用多模态成像，包括PET/CT扫描结合超声心动图，可以提高检测主动脉人工血管感染、人工瓣膜感染或心内装置感染的诊断准确性，尤其是在高风险手术病例中。
