Pulmonary artery banding is a palliative surgical procedure used to decrease excessive pulmonary blood flow. It is usually used for neonates and infants with left-to-right shunts unable to withstand complete surgical correction.
Some indications include:
single ventricle
multiple ventricular septal defects
unrepaired transposition of the great arteries in neonates to prepare the left ventricle to receive a higher systemic pressure load prior to arterial switch procedure

Procedure
The technique of pulmonary artery banding usually involves encircling the main pulmonary artery with a ring of prosthetic material, which restricts pulmonary blood flow, increases systemic perfusion and protects the pulmonary vasculature from changes of pulmonary hypertension.
Complications
Complications of pulmonary artery banding include:
dilatation of the proximal pulmonary artery
pulmonary valve insufficiency
pulmonary valve injury
band migration which may compromise blood flow
History and etymology
The procedure was introduced by William H Muller, Jr and J Francis Dammann, Jr in 1951 and was initially used in an infant with a ventricular septal defect.
