Vascular graft infection (VGI) is a serious complication, prognosis and treatment depend on early diagnosis. Current imaging methods have different applications and value in VGI. Plain film does not have a major role for diagnosis of VGI. It is suspected when perigraft gas is present. Ultrasound (US) is used for basic diagnostic due to availability, costs and rapid use. Evaluates graft morphology, anastomosis, native vessels, surrounding tissues and fluid collections. DopplerUS determines flow disturbances. Computed Tomography (CT) is currently the choice imaging method. Examines all anatomic regions. Grafts are visualised to full extension. Detects perigraft fluid, perigraft soft-tissue attenuation, ectopic gas and pseudoaneurysms. In low-grade infection, sensitivity decreases as morphological changes are difficult to distinguish from postoperatory changes. CT examines vascular and perivascular masses, ectopic gas and fluid collections, native adjacent arteries, arterial grafts and their lumen, venous system and other pathologies that can explain graft infection. CT detects aortoenteric fistulas, can distinguish between enteric loops and interenteric abscess and bleeding after graft infection. Provides image guidance for aspiration of fluid collections and percutaneous drainage placement. Magnetic Resonance Imaging (MRI) has proven accuracy in diagnosis of aortic VGI. Some disadvantages compared with CT are higher costs, less availability and more time spending procedure. It Is superior to CT for detection of perivascular inflammatory changes and small amounts of periprosthetic fluid MRI evaluation. Angiography has limited value for VGI diagnosis but is used for complications of VGI as pseudoaneurysms, rupture or graft thrombosis in order to perform endovascular treatment.
