Ruptured aortic aneurysm associated with diffuse salmonellosis: A case report

Abstract

Case report: A 63-year-old female patient, hypertensive and diabetic, reported a sudden onset of chest pain at night, which persisted continuously for 20 days. According to CT scans and computed tomography angiography, the diagnostic hypothesis of ruptured thoracic aortic aneurysm was considered. During the postoperative evolution, the patient presented difficulty in extubation and persistence of infectious symptoms, because of this, new tests were performed, which indicated a possible fistula with subsequent upper digestive endoscopy. During this period, the patient persisted with infectious symptoms and lack of improvement. Bronchoalveolar lavage fluid culture was performed at the same time, which identified bacterial growth of Salmonella spp. Discussion: A study that analyzed 129 cases of Salmonella in a hospital in Massachusetts showed that DM is one of the most common risk factors for Salmonella spp in adults. In a study carried out in China, it was evident that 28.9% of the cases were considered asymptomatic, that is: presence of the bacteria, but absence of diarrhea. In the scientific society, there is concern about the antimicrobial resistance of Salmonella spp. Because of this, treatment with antibiotics is indicated, especially in cases with a higher risk of complications. It is considered that the consequences of the bacterium on the body can lead the patient to septic shock and death. Final considerations: Thus, having knowledge about triggering factors, main symptoms, and appropriate treatment becomes essential for the best evolution of the clinical condition of infected patients.
