We report a case of successful reoperation with a bifurcated nonvalved extracardiac conduit for stenosis of the valved conduit and the pulmonary bifurcation after a Ross-Rastelli operation. The patient was 11-year-old female, who had undergone Ross-Rastelli operation with a 16 mm Carpentier-Edwards valved conduit for pulmonary atresia with ventricular septal defect at six year-old following Blalock-Taussig shunt at four year-old. She required reoperation for progressive right heart failure due to stenosis of the valved conduit and the pulmonary bifurcation. The reoperation was performed under cardiopulmonary bypass with aortic crossclamp. The stenosed valved conduit placed between the right ventricle and the right pulmonary artery was removed and replaced with 18 mm EPTFE graft. Because the direct repair of the pulmonary bifurcation stenosis was thought to be difficult, a 12 mm ringed EPTFE graft was anastomosed to the left pulmonary artery distal to the bifurcation stenosis as a branch of the 18 mm EPTFE main graft. Although transitional heart failure required IABP support in her early postoperative course, she subsequently recovered and discharged the hospital at the 37th postoperative day. Her right ventricular pressure reduced from 105 mmHg to 54 mmHg by the cardiac catheterization. She is now alive and well without any complaints.
我们报告了一例在Ross-Rastelli手术后,使用分叉无瓣心外管道成功进行再次手术,以治疗带瓣管道和肺动脉分叉处狭窄的病例。患者为11岁女性,4岁时接受了Blalock-Taussig分流术,6岁时因室间隔缺损合并肺动脉闭锁接受了Ross-Rastelli手术,使用了16mm的Carpentier-Edwards带瓣管道。由于带瓣管道和肺动脉分叉处狭窄导致进行性右心衰竭,她需要再次手术。再次手术在体外循环和主动脉阻断下进行。移除了位于右心室和右肺动脉之间的狭窄带瓣管道,并用18mm的eptfe移植物进行替换。由于认为直接修复肺动脉分叉处狭窄困难,将一个12mm的带环eptfe移植物作为18mm eptfe主移植物的分支,吻合到分叉处狭窄远端的左肺动脉。尽管术后早期因过渡性心力衰竭需要IABP支持,但她随后康复,并在术后第37天出院。通过心导管检查,她的右心室压力从105mmHg降至54mmHg。她现在生活良好,无任何不适。
