Abstract: | PurposeInfectious aortic aneurysms are rare, being responsible of less than 3% of aortic aneurysms. In this study, we report the clinical characteristics and the outcome of patients presenting with infectious aortic aneurysms in an internal medicine unit.MethodsDiagnosis of infection-related aortic aneurysm was obtained using: computed tomographic scan; and blood cultures, cultures and molecular biology testing of aortic wall and intra-aneurismal thrombus.ResultsThe 10 consecutive patients included in this study consisted in eight men and two women with a mean age of 61.7 years. Patients presented with fever (n = 9), asthenia (n = 2), abdominal (n = 4) or chest pain (n = 1), lumbar pain (n = 3). Computed tomographic scan showed aneurysm involving both thoracic and abdominal aorta (n = 1), abdominal (n = 8) or thoracic aorta (n = 1). Isolated microorganisms were: positive Gram cocci (70%) and negative Gram bacilli (30%). All patients underwent both medical and surgical therapy. Outcome was favorable in nine patients; the remaining patient died from aneurismal aortic rupture.ConclusionClinical manifestations revealing infectious aortic aneurysms are variable, including aneurysm rupture as well as atypical abdominal pain with inflammatory syndrome. These latter presentations are more common in patients, who are hospitalized in internal medicine. Our study underlines that this clinical pattern should not be ignored, in order to avoid both diagnostic and therapeutic delay that could lead to life-threatening complications and poor prognosis. |
