Abstract

Four patients (3 with surgically corrected tetralogy of Fallot and 1 with atrial septal defect) received 6 stents for peripheral pulmonary artery stenoses. In 3 patients, stenting was performed for inadequate results of balloon dilatation (elastic recoil in 2 and incomplete dilatation in 1). One patient received a stent without prior angioplasty. Three Palmaz-Schatz stents (6-14 mm diameter, 15-30 mm length) and 3 Strecker stents (7-9 mm diameter, 40 mm length) were used. The procedure was successful in 2 cases, in whom pulmonary artery pressures dropped from a peak of 90 and 94 mm Hg, to 60 and 30 mm Hg, respectively. Translesional gradients diminished from 78 to 20 mm Hg and 90 to 10 mm Hg, respectively, and pulmonary perfusion scintigraphy revealed an increase in perfusion of the affected lung from 28% to 49% and 22% to 46%,respectively. In 1 patient stenting was only partially successful dueto incomplete expansion and distal migration of a Strecker stent in apressure resistant stenosis. In another patient stenting failed for the same reason. Stenting for peripheral pulmonary artery stenoses may be effective, but has to be restricted to lesions which yield to priorballoon dilatation.
