To improve the result of surgery for replacement of both aortic valve and ascending aorta, we developed a new technique which is characterized as follows. 1) The composite graft is made during surgery according to the operative findings with tilting disc valve and very low porosity woven Dacron graft. 2) Proximal anastomosis is reinforced by double fixation method. 3) Coronary arteries are reimplanted directly into the graft as a Carrel patch. Thirty-four patients underwent this surgery with no operative death. One died in the hospital and 4 died in the late stage unrelated to the surgical technique. We recommend this method as a new standard technique for replacement of both aortic valve and ascending aorta.
为提高主动脉瓣和升主动脉置换手术的效果，我们开发了一种新技术，其特点如下：1）术中根据手术所见，采用倾斜碟瓣和极低孔隙率编织涤纶移植物制作复合移植物。2）近端吻合采用双重固定法加强。3）冠状动脉作为卡雷尔补片直接重新植入移植物。34例患者接受了该手术，无手术死亡。1例在医院死亡，4例在后期死亡，与手术技术无关。我们推荐这种方法作为主动脉瓣和升主动脉置换的新标准技术。
