Percutaneous Drainage of Aortic Aneurysm Sac Abscesses Following Endovascular Aneurysm Repair

Purpose: To report preliminary experiences with the treatment of aortic aneurysm sac abscesses following prior endovascular aortic aneurysm repair (EVAR) using computerized tomography (CT)-guided percutaneous drainage. Case Reports: Three patients aged 73 to 78 years with aortic aneurysm sac infections following prior EVAR, 2 of which were associated with aortoduodenal fistula, underwent CT-guided percutaneous drainage and catheter placement. One patient had complete resolution of the aortic aneurysm sac abscess following percutaneous drainage; 1 patient was stabilized to eventual extraanatomic bypass, graft explantation, and fistula repair; and 1 patient was temporized to debridement and fistula repair with endograft preservation. Conclusion: CT-guided percutaneous drainage may be a helpful therapy in selected patients for the treatment of aortic aneurysm sac infections following EVAR.
