Abstract

SUBSTITUICAO DA VÁLVULA AÓRTICA COM HOMO E AUTOENXERTOS

É analisado o comportamento, por um período de mais de 15 anos, de 6/5 homoenxertos e autoenxertos em posição aórtica. A incidência de morte relacionada com o enxerto foi de 6,7%. A frequência de tromboembolismo foi de 1 por 2314 doentes-anos. A insuficiência valvular foi mais frequente no caso de homoenxertos «freeze-dried». A endocardite infecciosa foi rara. Pensa-se que poucos homoenxertos continuarão a funcionar bem 20 anos após a implantação, mas 42% entrarão na 2ª década de existência sem terem tido complicações. Os autoenxertos revelaram uma incidência muito menor de degenerescência. Muitas das complicações associadas com os homo e autoenxertos aparecem gradualmente uma reintervenção electiva
