Hypothermic retrograde cerebral perfusion has been a successful method of cerebral protection during aortic

The Surgical Management of a Giant Innominate Artery Aneurysm in a Patient With Coronary Disease: A Case Report

“…Studies have shown that IAA is mainly caused by atherosclerosis; however, other causes may include vasculitis, either infectious like syphilis or tuberculosis [4][5]. A study reported that among 120 patients with IAA, the etiology was unknown in 58.3% [6][7]. IAA represents 3% of supra-aortic vessel aneurysms and can lead to devastating complications [8].…”

“…IAA represents 3% of supra-aortic vessel aneurysms and can lead to devastating complications [8]. The rupture rate is 11% in these patients, especially when the diameter exceeds 3 cm, in which case the risk of rupture will be higher [3][4][5][6][7][8][9].…”

Early Diagnosis and Treatment of a Posttraumatic Pseudoaneurysm/Dissection of the Innominate Artery

“…Radiologic clues of thoracic vascular injury include widening (> 8 centimeters) of the superior mediastinum, apical pleural capping, obscuration of the aortic knob, fractured first rib, depression of the left main bronchus (> 140 degrees from trachea) and deviation of nasogastric tube in the esophagus away from the midline 9 …”

“…140 degrees from trachea) and deviation of nasogastric tube in the esophagus away from the midline. 9 In a hemodynamically stable patient, angiography is mandatory. Computerized tomography and magnetic resonance imaging (MRI) are not recommended because they provide only circumstantial evidence of aortic injury.…”

Lesão do esôfago e de tronco braquiocefálico em trauma fechado: uma associação incomum

“…Em virtude dos fatos relatados, o diagnóstico das lesões supra-aórticas está diretamente ligado a exames subsidiários, em especial radiografia simples de tórax e angiografia 3,13,15,16 , como foi feito no caso relatado. As principais alterações na radiografia são o alargamento em mediastino superior (63%), fraturas de costela, clavícula, pneumotórax, derrame pleural, aumento da inclinação do brônquio fonte esquerdo, hematoma extrapleural, entre outros 10,15,16,18 . A angiografia é o principal método responsável por 77% dos diagnósticos 15 , sendo considerado o exame padrão 3,13,15,16 .…”
