在法乐氏四联症的修复中,决定是否需要施行跨越肺动脉瓣环的补片矫形很为重要。有些研究显示,施行这种矫形有较高的医院死亡率,其造成的肺动脉瓣关闭不全较单纯瓣膜交界切开者更为严重。因此,仅对那些确实需要的病人才作跨越瓣环的矫形术(以下简称越环矫形)。 In the repair of tetralogy of Fallot, it is important to decide whether or not to have a patch orthopedic across the pulmonary valve annulus. Some studies have shown that the implementation of this orthosis has a higher hospital mortality rate, resulting in pulmonary insufficiency than simple valvular junction incision were more serious. Therefore, orthopedic surgery (hereinafter referred to as “ring-ring orthopedic”) is performed only for those patients who really need it.
