Abstract:O tratamento cirúrgico, iniciado há muitos anos 1. 3. 8, vem sofrendo modificações técnicas 2. 4-7, sendo hoje realizado com bons resultados em um grande núme-ro de pacientes.Neste trabalho, será analisada a experiência acumulada nos últimos 11 anos, para o tratamento da dissecção da aorta e suas complicações, assim como as diferentes técnicas operatórias.
CASUfSTICA E MÉTODOSEntre janeiro de 1979 e dezembro de 1,989, 81 pacientes foram operados para tratamento da dissecção da aorta, com um total de 85 operaçõ… Show more
“…Deep hypothermia, with or without cardiocirculatory arrest, has been used for treating thoracic and thoracoabdominal aortic aneurysms and has been performed by establishing extracorporeal circulation between the aortic arch and right atrium 22,23,25,26 . In this study, deep internal hypothermia was induced by establishing extracorporeal circulation between the left atrium and the ascending aorta through the left auricle, because it provides more space for acting on the aneurysms of the aortic arch, mainly when those aneurysms are close to the subclavian artery, or yet, due to the large diameter of the descending aorta.…”

“…Currently, several methods of spinal cord protection exist, such as temporary bypass 13,14 , reimplantation of the intercostal arteries 15,16 , drainage of the cerebrospinal fluid [17][18][19] , deep hypothermia [20][21][22][23][24][25][26] , selective cooling of the spinal cord 21 , and pharmacological agents 27 . This study aimed at demonstrating the viability of the use of the extracorporeal circulation established between the left atrium and ascending aorta combined with deep hypothermia for correcting thoracic or thoracoabdominal aortic aneurysms.…”
ObjectiveTo demonstrate the viability of the use of extracorporeal circulation established between the left atrium and ascending aorta to induce deep hypothermia for correcting thoracic and thoracoabdominal aortic aneurysms.
MethodFrom January 1994 to July 2001, 38 patients (mean age, 54.6 ± 12.7 (20.6 ± 3.2ºC).
Results
Of the neurological complications, paraplegia occurred in
