Abstract
BACKGROUND: Accurate diagnosis of infected aortic and iliac aneurysms is often delayed, hampering timely treatment and potentially resulting in a fatal consequence. The aim of this study was to discover useful clinical features that can help physicians to identify these patients. METHODS: We reviewed the discharge notes from two hospitals and identified all patients who had a diagnosis of infected aneurysms of the thoracoabdominal aorta and iliac arteries between July 2009 and December 2013. Eighteen patients, aged from 41 to 93, were reviewed. Only 6 patients were diagnosed accurately in their first visit to our ED. RESULTS: Most patients had at least one underlying illness, and it took 1 to 30 (9.9±6.5) days for physicians to diagnose their infected aneurysm. Localized pain and fever were the two most commonly presented symptoms. The majority (92%) of isolated microorganisms were gram-negative bacilli, including Salmonella spp, Klebsiella pneumoniae, and Escherichia coli. Two of the 3 patients who underwent non-operative therapy died, and all of the patients who underwent a combination of medical and operative therapies survived. CONCLUSION: We suggest that physicians liberally use computed tomography scans on patients with unknown causes of pain and inflammatory processes. A combination of surgical and medical treatments is indicated for all patients with infected aortic and iliac aneurysms.
