Traumatic aorta injuries in a rural area: late manifestations and review of therapeutic aspects.

Traumatic thoracic aortic injuries (TTAI) are associated with high rates of morbidity and mortality. They are classified according to the extent of damage and computed tomography angiography has the highest sensitivity and specificity for identifying the degree of injury and potential associated lesions. Treatment strategies for TTAI are based on the type and extent of injury and associated lesions. The patient's degree of stability can also help to define the choice of treatment, which can be conventional or endovascular surgery (EVAR) or even conservative management in selected cases. Among patients with adequate vascular anatomy, endovascular surgery is associated with better survival and fewer risks. The objective of this article is to describe a series of four cases followed up at a tertiary service in a Brazilian state that has few centers that provide high complexity care. Endovascular therapy was employed as the preferred method. All four patients had favorable outcomes, with no complications up to discharge, and are currently in outpatient follow-up.

Incidental cardiovascular findings on chest CT scans requested for suspected COVID-19.

BACKGROUND: Computed tomography scans of the chest are often requested as a complementary examination to investigate a clinical suspicion of pulmonary disease caused by the novel coronavirus 19 (COVID-19). OBJECTIVES: Our objective was to analyze the prevalence of incidental cardiovascular findings on chest CT scans requested to assess radiological signs suggestive of COVID-19 infection. METHODS: This cross-sectional, descriptive, and retrospective study reviewed 1,444 chest tomographies conducted in the Radiology department of the Hospital de Clínicas Gaspar Vianna, from March 1 to July 30, 2020, describing the prevalence of images suggestive of viral pneumonia by COVID-19 and incidental pulmonary and cardiovascular findings. RESULTS: The mean age of the patients was 50.6 ± 16.4 years and female sex was more frequent. Computed tomography without contrast was the most frequently used method (97.2%). Aortic and coronary wall calcification and cardiomegaly were the most prevalent cardiovascular findings. CT angiography revealed aortic aneurysms (9.7%), aortic dissection (7.3%) and thoracic aortic ulcers (2.4%). CONCLUSIONS: Incidental cardiovascular findings occurred in about half of the chest CT scans of patients with suspected COVID-19, especially aortic calcifications, cardiomegaly, and coronary calcification.
