Surgical treatment of truncus arteriosus has been demonstrated to be optimized when approached in early infancy. In the past, the materials available, namely the 12-mm porcine valve Dacron conduit, restricted the size of the patient in whom early repair could be performed with increasing risk associated with decreasing age and size. The availability of homografts for reconstruction of right ventricular pulmonary artery continuity has allowed repair even in the neonatal period. Two hundred forty-four patients with truncus arteriosus have been operated on at the University of California San Francisco since 1975. In the past 5 years, 49 have been repaired using homograft reconstruction. The method of repair differs markedly from that of Dacron conduits, and specific points concerning homograft insertion including orientation, method of proximal anastomosis, and sizing are discussed in detail and the difference in insertion from the Dacron bovine heterograft conduit are discussed.
动脉干的外科治疗已证明在婴儿早期进行时效果最佳。过去，可用的材料，即12毫米的猪瓣膜涤纶管道，限制了能够进行早期修复的患者的体型，随着年龄和体型的减小，相关风险增加。同种异体移植物用于重建右心室肺动脉连续性，使得即使在新生儿期也能进行修复。自1975年以来，加利福尼亚大学旧金山分校已对244例动脉干患者进行了手术。在过去5年中，49例采用同种异体移植物重建进行了修复。修复方法与涤纶管道的方法明显不同，详细讨论了同种异体移植物植入的具体要点，包括方向、近端吻合方法和尺寸确定，并讨论了与涤纶牛异种移植管道植入的差异。
