Diagnostic imaging of traumatic pseudoaneurysm of the thoracic aorta Background. The purpose of the study was the presentation of findings and diagnostic imaging in patients with traumatic pseudoaneurysms of the thoracic aorta, as a rare consequence of road traffic accidents. Patients and methods. In 22 years we have found 8 traumatic pseudoaneurysms of the thoracic aorta, out of which 7 (87.5%) in male and 1 (12.5%) in female patients. At the time of accidents the youngest patient was 21 and the oldest was 55 (mean age 33.8 years), and at the moment of diagnosing a pseudoaneurysm they were 26 and 55 years old, respectively (mean age 38.7 years). In all patients chest radiography was performed as well as CT scan, in 6 (75%) patients intra-venous digital subtraction angiography was performed (i.v. DSA) and in 1 (12.5%) MRI. CT was performed with the application of 120 ml, and i.v. DSA with 60 ml of contrast medium, respectively. Results. In 8 (100%) patients, who suffered a road traffic accident, and whose chest radiograph showed the enlargement of the aortic knob and widening of the mediastinum, CT, i.v. DSA and MRI revealed a traumatic pseudoaneurysm of the thoracic aorta. Periods of time between the accidents and the initial diagnosis of the pseudoaneurysm varied from 7 days to 18 years (median 2.0 years). The diameter of the pseudoaneurysm was from 4.5 to 9.2 cm (median 5.5 cm). In 7 (87.5%) isthmus was involved, and in 1 (12.5%) descending thoracic aorta, respectively. The chest radiograph revealed marginal calcifications in 4 (50%), and on the CT in 5 (62.5%) patients. Intraluminal thrombosis was found by CT in 2(25%) traumatized patients. Conclusions. Traumatic pseudoaneurysm should be taken into consideration in blunt chest trauma, where a chest radiograph shows suspicious regions. A multislice CT is a diagnostic method of choice.

Review SUMMARY In recent years impressive progress is happening in information and telecommunication technologies. The application of computers in medicine allows permanent data storage, data transfer from one place to another, retrieving and data processing, data availability at all times, monitoring of patients over time, etc. This can significantly improve the medical profession. Medicine is one of the most intensive users of all types of information and telecommunication technology. Quickly and reliably store and transfer data (text, images, sounds, etc.) provides significant assistance and improvement in almost all medical procedures. In addition, data in locations far from medical centers can be of invaluable benefit, especially in emergency cases in which the decisive role has anesthesiologists.

Pacientes portadores de doenças crônicas em programa de transplante de órgãos sólidos apresentam condições sistêmicas que comprometem seu sistema imune, o que os predispõe a risco potencial de infecções, que devem ser prevenidas para o momento pós-transplante, principalmente diante do uso de imunossupressores. Os focos infecciosos em cavidade oral após o transplante são uma preocupação com essa condição e merecem atenção especial. Objetivo: Avaliar dados referentes à condição da saúde bucal de pacientes em programa de transplante de órgãos sólidos, buscando evidenciar a importância da assistência odontológica prévia. Métodos: Este estudo teve caráter quantitativo, descritivo, exploratório e retrospectivo, onde foram analisados 225 prontuários de pacientes em programa de transplante de fígado, rim e coração, os dados referentes à condição bucal e os possíveis riscos infecciosos (cáries, doença periodontal e lesões infecciosas de mucosas) obtidos nos relatórios de avaliação odontológica. Foram aplicados métodos estatísticos para análise de relevância através do teste de qui-quadrado e teste exato de Fisher com significância (p<0,05). Resultados: Foi registrada a presença de alterações bucais sinalizadoras de focos de infecção em (134/166) 80,72% pacientes em programa de transplante hepático, (35/43) 81,39% em programa de transplante renal e (13/16) 81,25% de transplante cardíaco. Conclusão: Os dados obtidos permitiram concluir que nos pacientes em programa de transplantes de órgãos, a incidência de focos infecciosos bucais é significativa e sugerem que a adequação bucal prévia aos transplantes é relevante diante da condição de imunossupressão a que aqueles pacientes são submetidos.
