Aneurismas e dissec？？es da aorta: progresso nos resultados imediatos do tratamento cirúrgico

after 1989, modifications were made for treatment of aortic aneurysm and dissection, they included: cardiocirculatory arrest, deep hypothermia, hemodynamic monitoring and others. between january 1980 and july 1994, 520 patients were submitted to surgical treatment of aortic aneurysms and dissection. the patients was divided into three groups according todiagnoses: ？ ascending aortic aneurysms (aaas) ？ aortic arch aneurysm (aaao) ？ aortic dissections type i and ii (daao i and ii) in the three groups the mortality was inferior to patients operated before 1989, predictive variables of death for aaas were: pulmonary complications (p = 0.0210), renal (p = 0.0310), neurological (p < 0.0001); for daao i and ii: arterial hypertension (p < 0.0001), cardiac complications (p < 0.0001), neurological (p < 0.0001), renal (p < 0.0001) and rupture (p < 0.0001) and for aaao, age (p = 0,001) and renal complications (p = 0.0015). the authors conclude that the modifications utilized in the method of surgical treatment for aortic aneurysm and dissections achieved better results.
