Item Acesso aberto (Open Access) Achados incidentais de aneurismas torácicos e abdominais(Universidade Federal do Pará, 2016-06) GÓES JUNIOR, Adenauer Marinho de Oliveira; FREIRE, Bárbara Íris Mascarenhas; RODRIGUES, Sofia Cunha; ANDRADE, Mariseth Carvalho de; FRANCO, Reinaldo Sérgio MonteiroBackground: Abdominal aortic aneurysms (AAAs) are the most common. The annual incidence of AAA rupture is eight cases per 100,000 inhabitants. Incidental detection can benefit patients if diameter is monitored and the correct treatment provided. Objectives: To estimate the prevalence of incidental diagnosis of thoracic aortic aneurysm (TAA) and AAA by computed tomography (CT); to determine prevalence by age and sex of patients and determine which arteries are involved and the morphological characteristics of the aneurysms; to determine the indications for CT most associated with incidental diagnosis of aneurysms. Methods: This was a descriptive, retrospective and randomized study. Inclusion criteria: patients over 50 years of age examined with CT of the thorax, abdomen or pelvis. Exclusion criteria: follow-up or diagnostic suspicion of aneurysms. Data collection instruments containing questions covering demographic and anatomic data were used. Results: A sample of 1,202 radiology reports was reviewed. A total of 27 aneurysms were detected (prevalence of 2.2%). Patients: 60% were male and 40% were female (p < 0.05). Sites: there were 13 cases (48.2%) in the ascending aorta (TAA); 7 (25.9%) in the infrarenal aorta (AAA); 2 (7.4%) at the thoracoabdominal transition of the aorta (TTA); 2 (7.4%) in the common iliac artery ; 1 (3.7%) in the internal iliac artery; 1 (3.7%) in the splenic artery; and 1 (3.7%) in the renal artery. Conclusions: The majority of patients were male (60%); TAA was the most common type (mean diameter: 4.1 cm), followed by AAA (mean diameter: 4.0 cm) and ATA (mean diameter: 3.9 cm). The most common indication for the CT examination that led to incidental diagnosis of an aneurysm was respiratory symptoms.
