Hybrid Treatment with Complete Transposition of Supra-Aortic Trunks versus Conventional Surgery for the Treatment of Aortic Arch Aneurysm.

OBJECTIVE: The disease of the aortic arch is traditionally approached by open surgical repair requiring cardiopulmonary bypass and circulatory arrest. This study performed a retrospective analysis comparing outcomes through primary hybrid patients submitted to aortic arch surgery without cardiopulmonary bypass with patients submitted to conventional open surgery. METHODS: 25 patients submitted to the aortic arch surgery were selected in the period 2003-2012 at the Madre Teresa Hospital in the city of Belo Horizonte, Brazil; 13 of these underwent hybrid technique without cardiopulmonary bypass and 12 underwent conventional open surgery. RESULTS: The mortality rate for the hybrid group was 23% and for the conventional surgery group was 17% (P=0.248). The postoperative complication rate was also similar in both groups, with no significant difference. CONCLUSION: Both techniques proved to be similar in mortality and morbidity. However, due to the small sample, more analytical studies with larger samples and long-term follow-up are needed to clarify this issue.

Substituiçäo do arco aórtico sem parada circulatória total: técnicas, táticas e resultados / Substitution of the aortic arch without total circulatory arrest: techniques, tactics and results

INTRODUÇÄO: A despeito dos avanços da cirurgia cardiovascular, das técnicas de circulaçäo extracorpórea e dos métodos de proteçäo cerebral, a mortalidade nas operaçöes de substituiçäo ou reparo do arco aórtico permanece elevada. As alteraçöes decorrentes da hipotermia profunda e as lesöes neurológicas ainda säo a maior causa de morbi-mortalidade. OBJETIVO: Demonstrar um conjunto de técnicas e táticas cirúrgicas que permite realizar a substituiçäo do arco aórtico sem a necessidade de hipotermia e parada circulatória total e apresentar os resultados alcançados em um grupo de 10 pacientes. CASUíSTICA E MÉTODOS: Dez pacientes do sexo masculino, com idade média de 48,7 anos, foram submetidos a substituiçäo do arco aórtico, utilizando-se hipotermia moderada, canulaçäo arterial em artéria subclávia direita e femoral esquerda, perfusäo cerebral seletiva pela artéria subclávia e confecçäo da anastomose dos vasos arco no primeiro tempo. RESULTADOS: O tempo médio de perfusäo cerebral seletiva foi de 14,1 minutos, de isquemia miocárdica 39,6 minutos e de circulaçäo extracorpórea 98,9 minutos. A temperatura esofágica média foi de 26,6º C (24º C a 30º C). O tempo médio de internaçäo foi de 18,4 dias (8 a 40). Näo ocorreram óbitos imediatos ou tardios. Dois pacientes apresentaram confusäo mental temporária e um apresentou hemiparesia que foi revertida. CONCLUSÖES: A combinaçäo de técnicas e táticas empregadas permitiu uma efetiva correçäo das lesöes em um campo cirúrgico amplo e seco. Ofereceu uma excelente proteçäo cerebral sem a necessidade de hipotermia profunda o que diminuiu substancialmente as complicaçöes pós-operatórias
