We report a 6-month-old infant with pulmonary atresia with ventricular septal defect who was successfully treated with a novel technique of percutaneous major aortopulmonary collateral artery (MAPCA) banding with a covered stent. He suffered from heart failure due to a residual MAPCA of 4.5 mm in diameter. A covered stent tied with 2 5-0 size nylon threads was successfully deployed into the MAPCA in a dumbbell shape with a banding diameter of 2.8 mm. Banding covered stent implantation is a useful method to reduce the pulmonary blood flow in patients with MAPCA, which could be a less-invasive alternative to surgery.
我们报告了一例 6 个月大的婴儿患有肺动脉闭锁伴室间隔缺损，成功地接受了经皮大主肺动脉侧支（MAPCA）带膜支架捆绑的新技术治疗。他因残留的 MAPCA 直径为 4.5mm 而患有心力衰竭。一个用 2 根 5-0 号尼龙线系住的带膜支架成功地以哑铃状形式部署到 MAPCA 中，其捆绑直径为 2.8mm。带膜支架捆绑术是一种减少 MAPCA 患者肺血流量的有效方法，它可能是一种比手术更具侵入性的替代方法。
