The presence of significant truncal valvular regurgitation presents a technically difficult and life-threatening challenge during operations for correction of the truncus arteriosus anomaly. The problem was encountered in 19 of 71 patients (26%) who underwent such operations. A simple technique for managing this problem, namely, temporary cusp approximation, has evolved and has proved successful in all 11 patients in which it was used. The indications for replacement of the regurgitant truncal valve have not yet been defined. The suggestion is made that in all but the most severe instances of truncal valvular regurgitation, persistence of the regurgitation postoperatively may currently be preferable to replacement of the valve.
在进行动脉干异常矫治手术时，显著的躯干瓣膜反流的存在带来了技术上困难且危及生命的挑战。在接受此类手术的71例患者中有19例（26%）遇到了这个问题。一种处理该问题的简单技术，即临时瓣叶靠拢术，已经形成并在其应用的所有11例患者中证明是成功的。反流性动脉干瓣膜置换的指征尚未明确。有人提出，除了最严重的动脉干瓣膜反流情况外，目前术后反流持续可能比瓣膜置换更可取。
