Hemodynamic repair in patients with pulmonary atresia, ventricular septal defect, hypoplastic pulmonary arteries with arborization defects, and major aortopulmonary collaterals necessitates prior unifocalization of pulmonary artery blood supply. When direct anastomosis between these collateral vessels and the central pulmonary arteries is not technically feasible, an interposition graft is required. Dacron, polytetrafluoroethylene, and pericardium have been used for this purpose. We describe our experience with the use of azygos vein as an interposition graft in 3 patients who underwent unifocalization of the pulmonary blood supply to the right lung. Our experience suggests that the azygos vein is a useful graft for use in this specific form of unifocalization procedure.
对于患有肺动脉闭锁、室间隔缺损、伴有分支缺陷的肺发育不全以及主要主肺动脉侧支的患者，进行血流动力学修复需要先对肺动脉供血进行单灶化处理。当这些侧支血管与中央肺动脉之间的直接吻合在技术上不可行时，就需要使用中间移植物。涤纶、聚四氟乙烯和心包已被用于此目的。我们描述了我们在3例接受右肺肺供血单灶化手术的患者中使用奇静脉作为中间移植物的经验。我们的经验表明，奇静脉是用于这种特定形式单灶化手术的有用移植物。
