A Case Report on Successful Nonsurgical Treatment Using Antibiotics Alone in Aortic Stent Infection Diagnosed by Positron Emission Tomography / 감염과화학요법

ABSTRACT

Aortic stent infection is a rare problem, but severe sequelae such as stent occlusion, aortic necrosis and rupture, and life-threatening sepsis can occur. Surgical removal and antibiotic therapy has been the mainstay of treatment, but the management of stent infection still remains controversial as to the time of removal operation or the prognosis regarding the use of antibiotics alone as the treatment modality. Recently, we experienced a case of delayed aortic stent infection that was treated with antibiotics alone. A 68-year-old man presented with unexplained fever of several days' duration. The patient had a history of having had an aortic stent inserted 8 years ago due to traumatic aortic rupture. Blood culture was positive for Staphylococcus aureus and positron emission tomography revealed focal intense nodular uptake at medial and inferior aspect of the aortic arch. He was therefore diagnosed with aortic stent infection due to Staphylococcus aureus and was successfully treated with name of antibiotics alone without recourse to surgery.
