Resumo

Contexto: Ainda são incomuns os estudos de prevalência de aneurismas viscerais raros, e os poucos estudos que focalizaram esses aneurismas observam taxas de prevalência em grupos de pacientes com aneurismas viscerais, mas pouco se conhece sobre a sua prevalência na população geral.

Objetivos: Avaliar a prevalência de aneurismas viscerais raros em angiotomografias realizadas para diagnóstico e seguimento de pacientes com diferentes patologias vasculares.

Métodos: Este estudo transversal partiu do acesso a todos os laudos de angiotomografias realizadas entre janeiro de 2005 e julho de 2021 em hospital privado de excelência situado na cidade de São Paulo. Foi utilizado um programa de mecanismo de busca de laudos pré-indexados, cuja base de dados é o Sistema de Informação Radiológica (RIS), para acesso aos laudos de pacientes com aneurismas intra-abdominais.

Resultados: Foram acessados laudos de angiotomografias de 92.883 pacientes, dos quais 2.597 (2,795%) apresentavam aneurismas intra-abdominais, sendo 937 (1,063%) viscerais, incluindo 158 (0,171%) aneurismas viscerais raros, mais frequente entre homens e nos seguintes segmentos: tronco celíaco (0,098%), artéria mesentérica superior (0,033%), artéria gástrica esquerda (0,010%), artéria pancreático-duodenal (0,009%), artéria gastroduodenal (0,005%) e arco pancreático (0,004%). Prevalências menores foram encontradas em outros diferentes segmentos. Achados adicionais revelaram taxa de concomitância de aneurismas viscerais raros com outros aneurismas intra-abdominais entre 11,11% e 66,67%.

Conclusões: A prevalência de aneurismas viscerais raros em ampla população submetida a angiotomografias foi de 0,171%, com maior comprometimento nos pacientes do sexo masculino.

Abstract

Background: Studies on the prevalence of rare visceral aneurysms are still scarce and the few studies that have focused on these aneurysms present prevalence rates in groups of patients with visceral aneurysms, but little is known about their prevalence in the general population.

Objectives: To assess the prevalence of rare visceral aneurysms on CAT scans performed for diagnosis and follow-up of patients with other vascular pathologies.

Methods: This cross-sectional study began by accessing all reports from CAT scans performed between January 2005 and July 2021 at a private hospital of excellence located in the city of São Paulo. A software program for pre-indexed reports was used to search the Radiological Information System (RIS) database to identify reports of patients with intra-abdominal aneurysms.

Results: CAT scan reports from 92,883 patients were accessed. Of these, 2,597 (2.795%) showed intra-abdominal aneurysms, 937 (1.063%) of which were visceral, including 158 (0.171%) rare visceral aneurysms, which were more frequent among male patients and in the following segments: celiac trunk (0.098%), superior mesenteric (0.033%), left gastric (0.010%), pancreatic-duodenal (0.009%), and gastroduodenal arteries (0.005%) and the pancreatic arch (0.004%). Lower prevalence was found in other segments. Additional findings revealed concomitance of rare visceral aneurysms with other intra-abdominal aneurysms ranging from 11.11% to 66.67%.

Conclusions: The prevalence of rare visceral aneurysms in a large population undergoing CAT scan was 0.171%, with greater involvement in male patients.
