CT-guided fine needle aspiration of a periaortic collection.
Patients with infected aortic grafts suffer considerable morbidity and mortality. Therefore, it is important to make the diagnosis of infection to provide a reasonable chance for survival. Clinical signs of infection are usually apparent in the postoperative period. If absent, the diagnosis becomes more difficult. CT scanning is beneficial in detecting periaortic fluid and gas collections; however, it cannot differentiate postoperative gas from infection in all cases. This is especially true during the first 2 weeks after operation. CT-guided fine needle aspiration can provide a safe and reliable means to answer this clinical question.
