摘要

A total of 5 Johnson and Johnson stents were implanted in two patients with significant residual peripheral pulmonary arterial stenosis. These were a 15-year-old boy with post-open heart surgery for tetralogy of Fallot and a 3 8/12 year-old boy with D-transposition of great vessels. Immediately after balloon dilatation and implantation of the stents, the diameter of the narrowing pulmonary arteries increased significantly from 6.0±0.8mm to 13.5±1.7mm (P＜0.001) and the systolic pressure gradients across the stenosis of peripheral pulmonary artery dropped significantly from 33.0±16.OmmHg to 10.2 ±4.4mmHg (P＜0.01). One year later, repeated cardiac catheterization was performed on both patients. In the patient with tetralogy of Fallot, a 20mmHg pressure gradient was found between the main and left pulmonary artery. This patient then received another stent implantation to release the residual stenosis. The boy with D-transposition of great vessels had only 9 mmHg gradient between main and right pulmonary artery. Transcatheter placement of the stent is a feasible and effective method to treat certain patients with significant pulmonary arterial stenosis if surgical correction can not be performed.
