A pulmonary artery band should be easy to apply and easy to remove at the definitive (second-stage) operation. It should be wide enough to allow pressure to be distributed over a large area to avoid erosion and scarring secondary to focal necrosis of the pulmonary artery.
We have used a knitted tubular Dacron lacing material, 5-mm wide when flattened, in 41 cases at the University of California, San Francisco, without acute injury or late rupture of the pulmonary artery (Fig 1). During later total correction of the ventricular septal defect in eight patients, the band was easily removed and the diameter of the pulmonary artery was restored by dilatation without the need for angioplasty.
Muller and Damman1 first described the clinical use of pulmonary artery constriction in 1952. The procedure has since been used extensively in infants to protect the lungs from the deleterious effects of excessive pulmonary blood
